…nd Solana Rhino prices a withdrawal as flat destination gas plus 0.07% of the amount, but returns a zero fee on part of the traffic. Over the 14 days to 2026-09-16 that was 6 of 26 Ethereum quotes, 17 of 38 Tron and 408 of 603 Solana — so the same route read as "Sponsored by Peanut!" or as $1.51 depending on the quote, and the user was told a real cost was free. The quote stays the source wherever it prices the route. Only a zero quote on the three chains whose flat gas is worth naming falls back to the published schedule, fitted from those priced quotes (Ethereum $1.50, Tron $1.40, Solana $0.50 flat). Every other network keeps the sponsored label — there the flat gas is cents and the label is honest.

/chip review Focus on the money-display path: the fallback only fires when Rhino's quote returns zero, and the flat-gas table is fitted from 14 days of prod quotes. Please check whether filling a zero quote with a schedule estimate can ever show a fee the user does not pay, and whether the destination chain id used for the lookup is always the one Rhino delivers to. |
A failed quote is not a zero fee. The row already shows a dash there, but the disproportionate-fee heads-up reads the same number, so the schedule estimate would have fed it a fee nobody quoted.

One blocking fee-display defect: an authenticated zero-fee quote is replaced with a positive client estimate, producing a phantom or internally inconsistent confirmation.
Findings
-
BLOCKING · src/app/(mobile-ui)/withdraw/crypto/page.tsx:823 · Do not override an authenticated zero-fee quote
When Rhino returns the zero quote this branch targets,payAmount,receiveAmount, andfeeUsddescribe one coherent zero-fee settlement, but this line replaces only the displayed fee. For example, a $5 Ethereum withdrawal can show about $1.50 as deducted while the same confirmation still says the recipient receives $5 and the user pays $5. Withdraw quotes use pay mode, so a real fee must reducereceiveAmount; Rhino's provider contract also says quoted fees and amounts are honored until expiry. This therefore either invents a fee before the account configuration changes or displays a fee absent from the quoted settlement. Keep zero authoritative until Rhino returns a coherent nonzero quote, or return and label a coherent estimated pay/receive/fee tuple from the backend. -
BLOCKING · src/utils/cross-chain-fee.utils.ts:59 · [claude-opus] App now charges a named withdrawal fee on three networks that product truth says are free
After this change, every cross-chain withdrawal to Ethereum, Tron or Solana displays a network fee — the quote when non-zero, otherwise the new CHAIN_FLAT_GAS_USD schedule ($1.50 / $1.40 / $0.50 plus RHINO_FEE_RATE), with copy reading "This is the fee the network charges to deliver. It comes out of the transfer." On the traffic the PR itself documents (408 of 603 Solana quotes, 17 of 38 Tron, 6 of 26 Ethereum returned zero), the fee is now shown where the app previously showed the sponsored label, so the schedule — not the quote — becomes the number those users see.
Product truth says the opposite, in three places. product/networks.md (last_updated 2026-09-09) lists fee: free for solana, tron and ethereum and states gas_coverage: "Peanut covers all gas fees on both deposit and withdrawal". product/pricing.md: "Peanut covers blockchain gas fees on both deposits and withdrawals via rhino.fi." The published help page content/help/withdraw-crypto/en.md answers "Are there any withdrawal fees?" with "No. All crypto withdrawals are free — Peanut covers gas fees on every network" (and the es-419 / pt-br variants match).
Which side is wrong: the code, on the evidence available. The schedule is fitted from Rhino's quotes, but peanut-api-ts treats the quote as unreliable for exactly this reason. src/transaction-intent/history.rhino-fee.test.ts opens with "The quote (rhinoFeeUsd) is display-only before the transfer and must never reach the receipt afterwards — pre-fix a $0.51 quoted fee showed on receipts for transfers Rhino delivered 1:1", and its second case books no fee at all for metadata carrying rhinoFeeUsd: 1.41 with rhinoExecutedAmountIn === rhinoExecutedAmountOut — a Tron-shaped quoted fee that was never actually taken. The ledger FEE entry and the receipt's networkFeeUsd both come from executed in − out. The estimate is frontend-only (provisionSdaTransfer still sends preview.feeUsd), so a user can be shown $1.54 on the confirm screen and then a receipt with no fee row at all, while the help page promises free.
Fix: settle the question against the settled actuals that already exist (the Rhino FEE ledger entries / rhinoExecutedAmountIn − rhinoExecutedAmountOut on completed CRYPTO_WITHDRAW intents), not the quote distribution. If the fee is real, this must ship with a product-truth update — product/networks.md per-network fee, the gas_coverage line, product/pricing.md, and content/help/withdraw-crypto/{en,es-419,pt-br}.md — via the product-fact path. If it is not real on the zero-quote routes, drop the fallback rather than name a fee the ledger will record as zero.
- MAJOR · src/features/withdraw/views/ConfirmWithdrawView.tsx:218 · [claude-opus] "It comes out of the transfer" is contradicted by the Recipient receives row on the fallback path
The new networkFeeChargedInfo copy tells the user the fee "comes out of the transfer", and the code comment says it is "taken on delivery when the schedule fills a zero quote". But the two adjacent rows are driven by the quote, not bynetworkFee:displayReceivedrendersreceiveAmountandtotalPayDisplayrenderspayAmount, both verbatim from Rhino (useCrossChainTransfer.ts:694-703; the withdraw flow quotes mode='pay', so a real fee shows up as a reduced receiveAmount).
On exactly the case this PR adds — a $50 withdrawal to Ethereum with a zero-fee quote — the card reads: Recipient receives $50.00, Network fee $1.53, You pay $50.00. Three numbers that do not reconcile, next to copy asserting the $1.53 is deducted from the delivery. The existing tests do not catch this because the page-level test mocks ConfirmWithdrawView down to the networkFee prop alone.
Fix: if the schedule is kept, derive the displayed receive amount from it on the fallback path (receiveAmount − estimate) so the rows agree, or mark the row as an estimate in the copy rather than asserting a deduction the other rows deny.

…zero fee Review found the premise wrong, and the settled actuals confirm it. On every completed withdrawal in the last 30 days whose quote was $0, Rhino deducted exactly $0.00 — Ethereum 4 of 4, Tron 6 of 6, Solana 406 of 406. A zero quote is not Rhino failing to price a route; it is Peanut sponsoring that route, and the quote, payAmount and receiveAmount describe one coherent zero-fee settlement. Overriding only the displayed fee produced a card whose three money rows did not reconcile, and a fee the ledger would record as zero. Sponsorship for Ethereum, Tron and Solana ends on Rhino's side, not ours (Ross Middleton call, 2026-09-16). When it does, the quotes carry the fee and the existing display shows it — with a matching receive amount, because withdraw quotes are pay-mode. What remains is the copy that was wrong either way: a withdrawal is quoted pay-mode, so the fee comes out of what the recipient receives. It was never "already included in the amount you pay".

Chip review — no blocking findings — this is not an approval
No findings. All three prior findings are resolved at this head.
Findings
- MAJOR · src/features/withdraw/views/ConfirmWithdrawView.tsx:218 · [claude-opus] "It comes out of the transfer" contradicts product truth: the quoted Rhino fee is not taken from the user
The new copy (en.json:1911, mirrored in es-419/pt-BR) is shown wheneverisCrossChain && networkFee > 0and states three things as fact: the network charges this fee, it is deducted from the delivery, and Peanut adds nothing. Product truth says the opposite on both of the first two.
Evidence:
- /home/chip/mono/product/networks.md:376-377 — "All fees (deposit and withdrawal) are free from Peanut. Gas fees on all stablecoin operations are covered by Peanut via rhino.fi"; each blockchain_networks entry carries
fee: free. - /home/chip/mono/product/financials.md:99 — destination gas per delivery is invoiced to Peanut (Σ quoted
rhinoFeeUsd), and explicitly: "The user pays $0 (1:1 account); the cost is ours." - /home/chip/mono/ops/rhino-fee-display-fix.md (implemented 2026-09-01) §2.2: over 880 CRYPTO_WITHDRAWs in the 60 days to 2026-09-01, $415.81 was quoted and $0.14 actually deducted; §2.4 states that pricing.md and networks.md are "correct" and that the nonzero quote is the public-endpoint schedule, not our authenticated account (§2.1: every route quotes $0 authenticated). peanut-api-ts/src/charge/ledger.ts:314-336 encodes the same conclusion — the quoted
rhinoFeeUsdis "a phantom" and is never booked; the ledger uses executed in − out.
So on a route where the quote comes back nonzero — still the majority of Ethereum quotes in the author's own 14-day sample in commit a95a959 — the card now tells the user $1.51 is coming out of their withdrawal, and (via the quote-derived Recipient receives row) shows a delivery lower than what settles. That is the mirror image of the bug ops/rhino-fee-display-fix.md was written to kill, and it contradicts the published fees page generated from product/. Secondary misattribution in the same sentence: Rhino's fees.feeUsd is gasFee + sourceGasFee + platformFee + percentageFee (0.07%), so it is not "the fee the network charges" — the sibling string one line up correctly separates the bridge cost from network cost.
The commit message argues sponsorship is ending on Rhino's side, which would eventually make this copy true — but nothing here shows a settled withdrawal where a nonzero quote produced a nonzero deduction; the evidence cited covers only zero-quote withdrawals settling at $0.
Fix: keep the row factual about the quote without promising a user deduction (e.g. "Rhino quotes this for delivery; Peanut covers it — you receive the full amount"), or, if sponsorship really has ended, land the product-truth update first (networks.md fee: free, pricing.md:232, financials.md:99) with a settled nonzero-deduction example, and only then ship copy that says the user pays it.
Checked clean
- Exact head and merge base matched the supplied SHAs; the final diff is limited to one explanatory comment and three localized tooltip strings.
- Withdraw quote flow remains pay-mode and renders the provider quote's payAmount, receiveAmount, and feeUsd verbatim, so the revised tooltip matches the displayed arithmetic.
- The authenticated zero-fee quote is no longer overridden and the hardcoded Ethereum, Tron, and Solana fee schedule is absent from both the final diff and head files.
- Live Lexicon terminology and canonical product fee/network sources were checked; current crypto withdrawals remain free from Peanut and the changed copy is shown only for a non-zero provider quote.
- Translation JSON parsed successfully. Exact-head unit, typecheck, format, eslint, design-system lint, native-export, and CodeQL checks completed successfully; the focused local test command could not start because the detached worktree has no node_modules.
Security review: did not run — this change has no security, privacy or money surface, so it was not asked. This review is one reviewer short.

Exact head: aa17aac8b52b · Context: repo, product, lexicon, ci · Took 6m
Superseded: Chip reviewed aa17aac and found nothing blocking. Dismissed so the pull request is not held by a review that no longer applies.
Peanut stops sponsoring the withdrawal fee on the three expensive networks, and Rhino enables the charge on their side (Ross Middleton call, 2026-09-16). A withdrawal of $50 to Ethereum now reads: recipient receives $48.465, network fee $1.53, you pay $50. Quotes issued before Rhino flips the charge come back at zero, so the fee is priced from their published schedule in that window — flat destination gas (Ethereum $1.50, Tron $1.40, Solana $0.50) plus 0.07%, fitted from 14 days of their quotes. A quote that does price the route always wins. The scheduled fee is held apart from the quoted one because only it is missing from `receiveAmount`: withdraw quotes are pay-mode, so a quoted fee is already deducted from the delivery. Review caught the card promising the full amount beside a fee — the scheduled fee now comes off the delivery too, converted through the destination token's price so an ETH withdrawal is not reduced by dollars. An in-flight or failed quote prices nothing; the row shows a spinner or a dash, and the heads-up stays quiet.

The zero-quote fallback still overrides Rhino's authenticated economics; canonical product truth remains free, and the minimum Solana path does not reconcile.
Findings
-
BLOCKING · src/app/(mobile-ui)/withdraw/crypto/page.tsx:827 · Keep an authenticated zero quote authoritative — also flagged by moonshotai/kimi-k3
When Rhino returnsfeeUsd: 0for Ethereum, Tron, or Solana, this branch replaces that authenticated result with a scheduled fee andreceiveAmountAfterFeelowers only the confirmation display. Execution still uses the quote's unchangedpayAmount/receiveAmount, while receipts and accounting use executed actuals, so a currently free withdrawal is presented as charged and the confirmed recipient amount can disagree with settlement. Remove the zero-quote fallback and render the authenticated quote; once Rhino enables the charge, its non-zero pay-mode quote already contains the correct fee and receive amount. -
MAJOR · src/utils/cross-chain-fee.utils.ts:62 · Do not ship the fee table ahead of product truth
This table makes Ethereum, Tron, and Solana withdrawals appear user-paid, but the canonical product sources still define crypto sends/withdrawals as free, state that Peanut covers all withdrawal gas, and the Rhino handover explicitly requires authenticated quotes with no hardcoded fee table. That leaves the app, support/content, receipts, and accounting with conflicting fee semantics. Update the canonical product/operations truth as part of the coordinated rollout before enabling this behavior, or keep the quote-only implementation until those sources and Rhino's configuration change together. -
MAJOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:846 · Handle a scheduled fee that consumes the delivery
A $0.50 Solana withdrawal is allowed by the current per-network minimum, but the fallback computes a $0.50035 fee. The resultingnetis non-positive, so this guard returns the originalreceiveAmount; the confirmation then shows roughly $0.50 received, $0.50 fee, and $0.50 paid while the tooltip says the fee comes out of the received amount. Reject or re-price a route whose fee leaves no positive delivery, and add the minimum-Solana case to the confirmation tests. -
BLOCKING · src/utils/cross-chain-fee.utils.ts:59 · [claude-opus] App names a withdrawal fee on three networks product truth says are free
The app now prices and names a network fee on Ethereum, Tron and Solana withdrawals, and deducts it from 'Recipient receives'. Product truth says the opposite, in four places: product/pricing.md:232 'Peanut covers blockchain gas fees on both deposits and withdrawals via rhino.fi' and its crypto-send-to-wallet entry (fee: free); product/networks.md:189 gas_coverage: 'Peanut covers all gas fees on both deposit and withdrawal' and :377 'All fees (deposit and withdrawal) are free from Peanut'; and the live customer-facing page content/help/withdraw-crypto/en.md:46 'No. All crypto withdrawals are free — Peanut covers gas fees on every network' (plus the es-419 and pt-br translations).
The code is the wrong side here, on the evidence already in mono. CHAIN_FLAT_GAS_USD ($1.50 Ethereum, $1.40 Tron, $0.50 Solana) plus RHINO_FEE_RATE 0.07% is exactly Rhino's public quote schedule, which ops/rhino-fee-display-fix.md §2.1 measured as not applying to Peanut's account (authenticated quote: pay 10.00 → receive 10.00, fee $0 on every one of those routes) and §2.2 measured against 880 prod withdrawals: $415.81 quoted and collected from users vs $0.14 actually deducted. §2.4 states explicitly that pricing.md and networks.md are correct. peanut-api-ts encodes the same conclusion — src/rhino/service.ts:378-384 calls the public schedule 'a phantom fee' and is the reason the API switched to the authenticated quote. financials.md §2d confirms the mechanism: Rhino invoices Peanut monthly for destination gas — 'The user pays $0 (1:1 account); the cost is ours' — so nothing is deducted from the delivery for the schedule to reproduce.
Concrete failure: a $50 USDC withdrawal to Ethereum gets an authenticated quote of feeUsd 0 / receiveAmount 50; this code overrides it to a $1.535 fee and shows 'Recipient receives 48.465'. Rhino delivers 50. The backend receipt, which reads executed actuals (src/transaction-intent/history.rhino-fee.test.ts: 'a 1:1 delivery shows no fee even though a quote was recorded'), then shows networkFeeUsd null and the full 50 — so the confirm screen, the help centre and the receipt all disagree for the same withdrawal.
The fix: land the policy before the code. If Peanut really is ending the sponsorship (the Ross Middleton call the comment cites is not recorded anywhere in mono/product or mono/ops), update product/pricing.md, product/networks.md and regenerate content/help/withdraw-crypto in all three locales via the update-content path first, and implement the charge where the ops doc puts it — a Rhino-side surcharge that the authenticated quote returns in feeUsd, which both surfaces then pick up with no arithmetic in the client. Until Rhino actually charges it, estimateRhinoNetworkFeeUsd should not override a zero authenticated quote.

…fees are per-network Rhino's route minimum predates the fee, so it still admits an amount the fee takes whole: $0.50 to Solana clears the $0.50 floor and costs $0.50035 to deliver. The delivery subtraction saw a non-positive result and fell back to the full amount, so the card read $0.50 received, $0.50 fee, $0.50 paid. Block the route instead, and name the number. The fee tooltip now says fees differ by network, and that Arbitrum is free — the row is the first place a user learns that picking another network is an option.

BLOCKING · page.tsx:827 · keep an authenticated zero quote authoritative (with kimi-k3) and BLOCKING · [claude-opus] product truth says these are free — the product-truth half is answered above. On the economics, the disagreement is real and I want to be precise about what is and is not claimed: You are right that today a zero quote is a coherent 1:1 settlement and that overriding it would misstate the delivery. That is exactly why this PR does not merge on its own. Peanut is ending the sponsorship, Rhino enables the charge on their side, and Aleks is pinging them to switch it on as this merges — the app and the account flip together. Quotes then return the fee and the schedule stops being consulted, which is the end state you describe ("its non-zero pay-mode quote already contains the correct fee and receive amount"). The table exists only for the window where the account charges and older quotes still read zero. What I cannot refute, and am not: if this merges and Rhino does not enable the charge, the screen names a fee nobody takes. That is a release-sequencing risk, not a code defect, and it is stated at the top of the PR body under Risks. The human approving this owns that call — I have left it as the first thing they read rather than resolving it away. Also fixed from the earlier round, for the record: the fee is now priced only once the quote resolves, so an in-flight or failed quote prices nothing and the heads-up stays quiet. |

Chip review — no blocking findings — this is not an approval
The fee behavior now matches current product truth and relevant CI is green, but a new public source comment discloses internal commercial and account-usage information.
Findings
-
MAJOR · src/utils/cross-chain-fee.utils.ts:47 · Keep internal commercial context out of the public repository
This newly added comment records internal vendor-spend and individual-account usage context in peanut-ui, which is public. Merging makes that operational information part of the permanent public source history even though it is not needed to explain the calculation. Replace it with a technical rationale (these destinations have higher fixed delivery costs) and keep commercial/account evidence in the internal product source. -
BLOCKING · src/utils/cross-chain-fee.utils.ts:62 · [claude-opus] App charges a withdrawal fee on three networks product truth and peanut.me say are free
CHAIN_FLAT_GAS_USDprices $1.50 (Ethereum), $1.40 (Tron) and $0.50 (Solana) plus 0.07%, the confirm card names it as a network fee, andreceiveAmountAfterFeededucts it from what the recipient gets. Product truth says the opposite, in four places: -
/home/chip/mono/product/networks.md:6 — "Withdrawals: all free from Peanut"; :189 gas_coverage: "Peanut covers all gas fees on both deposit and withdrawal"; :377 "Gas fees on all stablecoin operations are covered by Peanut via rhino.fi".
-
/home/chip/mono/product/pricing.md — "Peanut covers blockchain gas fees on both deposits and withdrawals via rhino.fi"; crypto-send-to-wallet: free.
-
/home/chip/mono/product/support-answers/fees-questions.md — the answer support gives today ends "Gas is covered by Peanut."
-
The live public pages, most explicitly: content/withdraw/ethereum/en.md:60-61 ("Peanut fee | Free", "Gas fee | Covered by Peanut"), :78 "None. Peanut covers all gas fees on Ethereum withdrawals... The withdrawal is completely free." Identical claims in content/withdraw/tron/en.md:63-64,83 and content/withdraw/solana/en.md:60-61,76.
The code is the newer fact — the table cites the Ross Middleton call of 2026-09-16 — so product truth is what is wrong, but it has not been changed: git log product/ shows no commit for this, and today a user withdrawing $10 to Ethereum would see ~$8.50 arrive while peanut.me and support both promise the withdrawal is free. A narrower instance: product/networks.md:33 documents a $0.50 Solana withdrawal minimum, and the new block at page.tsx:906 rejects exactly $0.50 to Solana because the fee ($0.50035) is not less than the amount.
Fix: land the product-truth change first (product/networks.md, product/pricing.md, product/support-answers/fees-questions.md, and regenerate the three withdraw pages plus the fees page — the update-content / product-fact path), including the revised Solana minimum, then merge this. Same issue as P5/P3.
- MINOR · src/i18n/app/messages/en.json:1910 · [claude-opus] Free-network tooltip names Ethereum and Tron but not Solana, which this PR also charges
networkFeeInfo— shown whenever the fee row is zero, i.e. to every user on a sponsored network — reads "Delivering on this network is free — Peanut covers it. Some networks, like Ethereum and Tron, charge a fee that comes out of the amount received." Solana is missing, yetCHAIN_FLAT_GAS_USDcharges it $0.50 flat (src/utils/cross-chain-fee.utils.ts:64) and the PR title itself says "Ethereum, Tron and Solana". A user on Arbitrum who reads the tooltip and then picks Solana in the network picker is told, in the app, that the charging networks are Ethereum and Tron — and then pays. The copy is the wrong side here; the fee table and the PR's own stated scope include Solana. Fix: name all three in en.json:1910 and mirror it in es-419.json and pt-BR.json.

…ana in the tooltip peanut-ui is public, so the fee table's comment should not carry what Rhino bills us or what one account cost. It now gives the technical reason — these destinations cost far more to deliver to — and points at mono for the policy. The free-network tooltip listed Ethereum and Tron as the ones that charge and left out Solana, which this same change charges. A user on Arbitrum reading it and then picking Solana was told the wrong thing by the app itself.

Head is now MAJOR · cross-chain-fee.utils.ts:47 · keep internal commercial context out of the public repository — fixed, and this was the right catch. The comment carried what Rhino bills us and what a single account's usage cost, in a public repo and therefore in its permanent history. It now gives the technical reason — these three destinations cost far more to deliver to than an L2 — and points at MINOR · [claude-opus] free-network tooltip names Ethereum and Tron but not Solana — fixed in en, es-419 and pt-BR. You are right that this was the worst possible place for the omission: the tooltip is read by someone on a free network who is deciding which network to pick, and it was telling them Solana was safe. BLOCKING · [claude-opus] product truth says these are free — the product half landed before your review ran and your own primary pass confirms it ("Current mono main names Ethereum, Tron, and Solana as user-paid withdrawals with the same flat fees plus 0.07%; the previous product-truth findings P3 and P5 are fixed"); mono
The BLOCKING · page.tsx:828 · [kimi-k3] do not override an authenticated zero-fee quote — noted that your primary pass checked this and did not carry it. Nothing further from me beyond what is already at the top of the PR body: the app and Rhino's account flip together, and that sequencing is the approving human's call. |

Preserve a resolved zero Rhino fee. scheduledFeeUsd replaces feeUsd === 0 on affected cross-chain routes and receiveAmountAfterFee subtracts it from the displayed delivery. The RhinoQuote contract defines feeUsd as the total fee and receiveAmount as the destination amount after fees. A local estimate therefore adds a deduction that the zero-fee quote does not include. Keep receiveAmount unchanged when feeUsd is zero.

Chip review — changes requested
Authenticated zero-fee quotes are still overridden, Solana's $1 floor is not enforced, public pricing remains stale, and internal commercial analysis remains in public source.
Findings
-
BLOCKING · src/app/(mobile-ui)/withdraw/crypto/page.tsx:828 · Do not replace a resolved zero-fee quote with a schedule
For a resolved authenticated quote with feeUsd=0 on Ethereum, Tron, or Solana, this call manufactures a fee and receiveAmountAfterFee lowers only the confirmation display. Provisioning and execution still use the quote's feeUsd=0 and payAmount===receiveAmount, so the screen promises less than Rhino will deliver and names a charge Rhino did not quote. Treat a resolved zero as authoritative; enable Rhino before the app rollout, or expose an explicit backend flag instead of inferring enablement from the chain. -
BLOCKING · src/app/(mobile-ui)/withdraw/crypto/page.tsx:827 · Keep an authenticated zero quote authoritative
The quote hook already distinguishes undefined/loading/error from a completed numeric quote, but this guard treats only positive values as authoritative. A completed zero is a valid account-bound provider result (and the API sibling has an explicit zero-fee normalization case), so it must not fall through to client-side pricing. Return zero for the resolved quote or gate the schedule on an explicit server-owned rollout state. -
MAJOR · src/utils/cross-chain-fee.utils.ts:47 · Keep fee-analysis provenance out of the public repository
The public source still publishes internal commercial/operational provenance: the analysis window, percentile agreement, rollout timing, and private mono paths. The runtime constants and a short maintenance note are enough here; keep the derivation and commercial context in the internal product/ops source. -
MAJOR · src/utils/cross-chain-fee.utils.ts:62 · Update public fee promises before charging these networks
Product truth now authorizes this schedule, but the current public help, pricing, supported-networks, and per-network withdrawal pages still promise that Ethereum, Tron, and Solana withdrawals are free and gas is covered. Shipping the table first makes the app contradict the customer-facing contract on a money screen. Coordinate the content update with this release across every locale. -
MAJOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:906 · Enforce the new $1 Solana withdrawal minimum
Current product truth sets Solana's minimum withdrawal to $1, but this guard only blocks when the scheduled fee consumes the entire amount. For example, $0.51 passes the existing $0.50 route minimum and this check because the $0.500357 fee is slightly smaller, leaving less than one cent to deliver. Add Solana's $1 floor to the chain minimum used before charge creation and cover amounts between $0.50 and $1 in the flow tests. -
BLOCKING · src/utils/cross-chain-fee.utils.ts:62 · [claude-opus] Fee table reinstates the phantom Rhino quote against product truth
CHAIN_FLAT_GAS_USD+RHINO_FEE_RATEmake the app name and deduct a withdrawal fee on Ethereum, Tron and Solana. Product truth says the opposite and has not moved: /home/chip/mono/product/networks.md (last_updated 2026-09-09) carriesfee: freeon all six networks,# Withdrawals: all free from Peanut,gas_coverage: "Peanut covers all gas fees on both deposit and withdrawal", and the published page /home/chip/mono/content/pricing/en.md:143 says "Every action in the Peanut app is free — deposits, payments, withdrawals, and sends."
The code is the wrong side, and its own citation proves it. The comment at cross-chain-fee.utils.ts:44-46 points at "product/networks.md withdrawal_fee" — no such key exists anywhere under product/ — and at ops/rhino-fee-display-fix.md, which states the reverse: line 58, "product/pricing.md ... and product/networks.md (fee: free) are correct", and line 140, "Leave fee: free and pricing.md unchanged."
The numbers are the tell. That doc §1 identifies the bug it fixed as the app reading Rhino's public quote, "which returns the generic schedule (flat destination gas + 0.07%)". This PR's table is that schedule to the cent: $10 → Ethereum 1.50 + 0.0007·10 = $1.507 vs the doc's public quote $1.51; Solana $0.507 vs $0.51; Tron $1.407 vs $1.41. Peanut's authenticated quote on those same routes is $0 (§2.1), and 60 days of prod actuals (§2.2) show average real deductions of $0.00007 on Solana, $0.0001 on Ethereum and $0.012 on Tron against $415.81 quoted. So the claim in the comment that the table was "fitted from 14 days of their quotes" is fitted to the public quote, not to what Peanut's account is charged.
User-visible consequence, and it also contradicts the backend: peanut-api-ts books the ledger FEE entry and the receipt's networkFeeUsd from execution actuals only (charge/ledger.ts:318-328, transaction-intent/history.ts:1044-1048, asserted in history.rhino-fee.test.ts — a Tron intent with in == out yields networkFeeUsd: null). Confirm would promise "Network fee $1.535, recipient receives 48.465" while 50 actually lands and the receipt shows no fee at all. The new belowMinimumMessage branch (page.tsx:906) then blocks real, deliverable withdrawals — $0.50 to Solana costs Peanut $0.00007, not $0.50035.
Fix: do not ship the table. If the business has genuinely decided to stop sponsoring these three, that decision lands in mono first — update fee/withdrawal_fee in product/networks.md and product/pricing.md via the update-content skill, regenerate the public pages, and supersede ops/rhino-fee-display-fix.md — and the fee should come from Rhino's authenticated quote once Rhino enables the charge, not from a hardcoded client-side copy of their public schedule. Until then feeUsd verbatim (the pre-PR behaviour) is the correct display.

Closing in favour of a clean branch with no hardcoded fees: the fee is read from Rhino's authenticated quote, which is already fetched on every withdrawal attempt. Superseded by the PR linked below. |

Superseded by #3224 — same change, no hardcoded fee table. The fee is read from Rhino's authenticated quote, which the withdraw flow already fetches on every attempt. |

Summary
Peanut stops sponsoring the withdrawal fee on Ethereum, Tron and Solana. The confirm screen names that fee and takes it off what the recipient receives.
Rhino enables the charge on their side — agreed on the 2026-09-16 call with Ross Middleton (Rhino.fi co-founder), and switched on as this merges. Peanut keeps covering the fee everywhere else, where the flat destination gas is cents.
Rhino prices a withdrawal as flat destination gas + 0.07% of the amount. The app shows the quoted fee wherever the quote carries it. Quotes issued before the charge is enabled come back at zero, so in that window the fee is priced from Rhino's published schedule — Ethereum $1.50, Tron $1.40, Solana $0.50 flat, fitted from 14 days of their quotes (the median of
feeUsd − 0.0007 × amount, whose 50th and 90th percentile agree to the cent on all three chains). A quote that does price the route always wins over the schedule.Screenshots
$50 withdrawal, 375×667. The three money rows reconcile: receives + fee = you pay.
The fee tooltip
The "i" beside Network fee now says fees differ by network and names one that is free, so the row is where a user learns that picking another network is an option.
(The free-network shot was taken before Solana was added to that sentence; the text above is what ships.)
Captured from the running app with the real

The local sandbox cannot quote mainnet Ethereum and keeps Tron and Solana behind their rollout flags, so the three screens were rendered through a temporary dev route rather than by clicking the picker; that route is not part of this diff.

cross-chain-fee.utils.ts—estimateRhinoNetworkFeeUsd(chainId, amountUsd), the per-chain flat-gas table, andRHINO_FEE_RATE = 0.0007.withdraw/crypto/page.tsx— the scheduled fee is computed separately from the quoted one and subtracted from the delivery, because only the scheduled one is missing fromreceiveAmount: withdraw quotes are pay-mode (useCrossChainTransfer.ts:365), so a quoted fee is already deducted there. The subtraction converts through the destination token's price, so an ETH withdrawal loses ETH, not dollars.Risks
