Summary

Adds a Claim XE flow to the wallet. Holders send EDGE to the claims wallet and claim the same amount of XE on the new XE network, 1:1.

• Claim XE button on the account panel. It shows only when VITE_CLAIMS_API_URL is set and the claims service /info says claims are open.
• Claim modal: XE address, amount (MAX), a confirmation tick and the user's recent claims. A password step signs an EDGE transfer to the claims wallet with data: { memo: "Claim XE", ref }. The progress view follows the transfer: posted, in a block, 10+ confirmations, received by the claims service.
• Lost transfers: the Edge chain can accept a transfer and then drop it. The modal follows the transfer by hash. When the transfer is gone and the wallet nonce is unused for three checks in a row, the EDGE did not move, so the claim shows as failed with Try again.
• XE address generator ("Create one" under the XE address field): makes a new XE account in the browser, shows its address and 24-word recovery phrase, offers New address until the user likes the address, then asks for 3 random words back. "Use this address" fills the claim form. Nothing is stored.
• Recovery phrase format: the 32-byte ed25519 seed written as 24 BIP39 English words (entropy-to-mnemonic on the seed itself, no PBKDF2, passphrase or derivation path). Address: SHA-256 of xe/account/v1 followed by the public key, as 64 lowercase hex. src/utils/xe-recovery-phrase-vectors.json holds the XE core test vectors.
• Text wrapping: no single-word last lines in the claim and generator modals.

Configuration

• VITE_CLAIMS_API_URL: the claims service URL. Unset hides the Claim XE button.

Dependencies

• @scure/bip39, @noble/curves, @noble/hashes (2.4).

Testing

• npm test: 117 tests pass, including the XE core recovery phrase vectors.
• ESLint is clean for every changed file.
• Browser tests against a local 3-node Edge devnet and the claims service:
  • claim to received, a dropped transfer shown as failed with Try again, the claims list;
  • generated address, New address and the 3-word check; XE core derives the same address from the shown words;
  • a layout audit for single-word last lines over 19 modal states, 8 widths (1920 to 360) and 3 fonts.
