feat(withdraw): show the network fee Rhino quotes for the delivery - #3224
Conversation
Peanut stops sponsoring the withdrawal fee on Ethereum, Tron and Solana, and Rhino enables the charge on their account. The confirm screen already reads the fee from Rhino's authenticated quote, so the number appears on its own the moment Rhino starts charging — and disappears again if a network goes back to being sponsored. Nothing in the client decides which networks charge. What this adds is the part the screen was getting wrong either way: 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 charged variant also stops claiming the fee is "already included in the amount you pay" — a withdrawal is quoted pay-mode, so the fee comes out of what the recipient receives, never on top of what the sender pays. A quote whose fee takes the whole amount is now blocked. Rhino's route minimum exists to stop the bridge rejecting a small deposit, not to keep the fee below the amount, so a small withdrawal to an expensive network could otherwise be confirmed with nothing left to deliver.

Chip review — no blocking findings — this is not an approval
The fee-aware guard still permits Solana withdrawals below the required $1 minimum.
Findings
-
MAJOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:871 · Enforce Solana's $1 withdrawal minimum
A $0.75 Solana withdrawal passes the existing $0.50 route minimum, and the new condition only rejects it when the quoted fee is at least the full amount. With Solana's roughly $0.50 fee, that attempt remains confirmable even though the current product contract sets the Solana withdrawal minimum to $1 after this fee change. Add Solana's $1 floor to getMinWithdrawUsdForChain (and cover the $0.50-$0.99 range) so the setup guard rejects these attempts before creating a charge. -
MINOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:871 · [claude-opus] Solana withdrawal minimum: code allows $0.51–$0.99, product truth says $1.00
product/networks.md setsminimum_withdrawal: "$1.00"for Solana with the comment "the route minimum is $0.50, but the fee must leave something to deliver" — the same rationale this PR implements. The implementation is weaker: the new guard only blocks whennetworkFee >= amountUsd, and the amount-step floor isgetMinWithdrawUsdForChain('solana')→MIN_CRYPTO_WITHDRAW_USD= 0.5 (src/utils/cross-chain-fee.utils.ts:54-68; only Ethereum and Tron have overrides). Failure case: user withdraws $0.60 to Solana. The amount step passes ($0.60 ≥ $0.50), the quote prices the route at $0.50 + 0.07% (product networks.md:32, matching the ops/rhino-fee-display-fix.md §2.1 schedule), the fee is less than the amount so the new guard does not fire, and the recipient receives about $0.10 — an ~83% fee withdrawal the product doc intended to block. Only the non-blocking high-fee heads-up appears. Note networks.md is internally inconsistent here: its header line says minimums are "as the app enforces them ($0.50 default; Ethereum $5; Tron $10)", which omits Solana. Fix one of the two deliberately: either addsolana: 1(and the numeric Solana id used by NON_EVM_WITHDRAW_CHAINS) toCHAIN_MIN_WITHDRAW_USDso the app enforces the published $1.00, or correct networks.md's Solanaminimum_withdrawalto $0.50 and let the fee guard be the only floor.
Checked clean
- Verified the detached worktree head, trusted author, main base SHA, and merge base against the supplied values.
- Traced Rhino pay-mode quote semantics through useCrossChainTransfer: payAmount is the spend, receiveAmount is net delivery, and feeUsd is used verbatim.
- Checked the canonical Lexicon mirror plus current network, pricing, support, and Rhino fee-plan product sources.
- Exact-head unit, typecheck, lint, format, native-export, CodeQL, and analysis checks succeeded; ds-shots was still running.
- Focused local Jest execution was unavailable because the detached worktree has no node_modules.

Four holes, all on the same guard. The gate measured the fee against `?amount=`, which stays editable after review, while the broadcast spends the amount pinned to the charge. Raising the URL amount cleared the gate and then moved the original one, delivering nothing. It reads the pinned amount now, and the spend re-checks the fee immediately before broadcasting — a render-time value cannot guard a click that happens later. Retry sits on its own branch and carried none of the gates, so a failed send was a way past them. It now refuses for the same reasons the confirm button does. That hole predates the fee: it already let a retry through the Rhino route minimum, which strands the deposit at the SDA. Solana's floor is $1. Rhino still accepts $0.50, but a delivery Peanut no longer sponsors costs about that much, so anything under a dollar arrives as dust. product/networks.md said $1 already; nothing enforced it. A failed quote no longer explains itself. The row shows a dash, and both tooltip strings are untrue there — one promises free delivery, the other describes a fee nobody quoted.

Chip review — no blocking findings — this is not an approval
The Solana $1 floor is fixed, but the new Retry gate can cut off record-only recovery after funds move, and the new fee gate bypasses localization.
Findings
-
MAJOR · src/features/withdraw/views/ConfirmWithdrawView.tsx:253 · Keep record-only Retry enabled after funds move
For a full-balance withdrawal, the on-chain spend can succeed and thenrecordPaymentcan fail. The page deliberately keepsexecutedSpendRefso Retry replays only bookkeeping, but once the wallet balance refreshes to zero,insufficientBalancebecomes true against the original spend and this new expression disables the only Retry button. The user can no longer run the record-only recovery, leaving the charge or activity record pending even though funds moved. Pass whether this charge was already spent and skip the balance/minimum CTA gates in that state (or leave Retry enabled and rely on the handler's existingalreadySpentexemptions), and cover a balance drop between the failed record and Retry. -
MINOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:885 · Localize the fee-consumes-withdrawal gate
With anes-419orpt-BRlocale, a quote whose fee equals the withdrawal renders this new blocking message in English before confirmation. The same change adds translatedwithdraw.errors.feeExceedsAmountstrings, but this render-time branch bypasses them. Use a localized message here, adding network and fee placeholders if those details need to remain visible. -
MINOR · src/utils/cross-chain-fee.utils.ts:71 · [claude-opus] Solana's new $1 floor also applies to link claims; product truth still enumerates $0.50/$5/$10
getMinWithdrawUsdForChainhas a second caller —src/utils/claim-min-guard.ts:22(belowClaimBridgeMinimum) — so addingsolana: 1raises the floor for Rhino-bridged Peanut Link claims to a Solana wallet as well as for withdrawals. Two places in product truth enumerate that floor and now disagree with the code: -
/home/chip/mono/product/send-links.md:25—minimum_amount_crosschain_claim: ... Floor is the destination network's: $0.50 default, $5 Ethereum, $10 Tron (see networks.md). A $0.75 Solana link claim is blocked after this merges; the doc says it is allowed. -
/home/chip/mono/product/networks.md:5—# Crypto withdrawal minimums are per network, as the app enforces them ($0.50 default; Ethereum $5; Tron $10).
The code is right and the docs are the stale side: networks.md's own Solana entry was set to minimum_withdrawal: "$1.00" on 2026-09-16 (commit d9e1f329, "the route minimum is $0.50, but the fee must leave something to deliver"), and networks.md:6 already routes link claims to the same per-network floor. Only the two summary enumerations were missed. They feed support answers (product/support-answers/fees-questions.md sources networks.md) and the generated help pages, so support will keep quoting $0.50 for Solana while the app refuses it.
Fix is in mono, not here: add Solana $1 to both enumerations (the /product-fact or /update-content path), so the app and the published floor agree on the day this ships.

The gates I just put on Retry also caught the one state where Retry is not trying to spend anything. When the on-chain leg lands and only recordPayment fails, the page keeps executedSpendRef so Retry replays the bookkeeping and never re-broadcasts — but the wallet has emptied by then, so the original spend reads as unaffordable and the balance gate disabled the only recovery. A full-balance withdrawal hits this every time, and the charge is left PENDING and missing from Activity with no way back. The gates now step aside once the spend has landed, which is what handleConfirmWithdrawal already does for the amount and fee checks. Before the spend they hold exactly as they did.

Chip review — no blocking findings — this is not an approval
One minor localization defect remains; the Solana floor, link-claim minimum, and record-only retry defects are fixed at this head.
Findings
- MINOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:885 · Localize the fee-consumes-withdrawal gate
For an es-419 or pt-BR user whose quoted network fee is greater than or equal to the pinned withdrawal amount, this newly added render-time gate displays the English template before signing, even though the tap-time recheck uses the translated feeExceedsAmount key. Route this message through next-intl (adding amount/network placeholders if the detailed copy is retained) so the disabled CTA explains the problem in the active locale.
Checked and not raised again
- MINOR · src/utils/cross-chain-fee.utils.ts:71 · [claude-opus] Solana's $1 floor also gates link claims; product truth still enumerates $0.50/$5/$10 — this review checked it and does not believe it. No task filed.
Checked clean
- Exact head and merge base matched the supplied SHAs, and trusted PR metadata matched the requested author, base, and head.
- Reviewed withdrawal fee and minimum guards, stale-quote handling, post-spend record-only retry behavior, and the shared link-claim minimum path.
- The canonical Lexicon had no conflicting term; mono product truth requires a $1 Solana floor and applies the same per-network floor to Rhino-routed link claims.
- Exact-head unit, typecheck, eslint, format, native-export, and CodeQL checks succeeded; ds-shots was still in progress.
- A local focused Jest run was unavailable because this detached worktree has no Jest binary, so test verification relied on the exact-head CI unit result.

Peanut stops sponsoring the withdrawal fee on Ethereum, Tron and Solana. Rhino enables the charge on our account, and this ships with it.
The fee comes from Rhino, not from us
The confirm screen already asks Rhino for a quote on every withdrawal attempt, and that quote carries the fee. So the moment Rhino starts charging, the number appears by itself — and if a network goes back to being sponsored, it disappears by itself too.
There is no fee table in this PR. Nothing in the app decides which networks charge or what they cost. That also keeps the three money rows honest for free: a withdrawal is quoted pay-mode, so Rhino returns the delivery with the fee already taken off, and the card shows its numbers without doing any arithmetic on them.
