Everything else is already correct for THIS challenge and should not be rebuilt — `accepted` in particular must stay byte-identical to what we offered. Amounts and times are decimal STRINGS, not numbers. validBefore is unix seconds and this one is good for the maxTimeoutSeconds above; a fresh GET always yields a fresh challenge. One more wall waits after the envelope and it fails silently: the EIP-712 domain must be built from accepted.extra (name, version), the chainId of the accepted entry's own network (eip155:8453 → 8453, eip155:137 → 137), and verifyingContract = accepted.asset — details at the hand_rolling_url. The solana:* entry in accepts takes a signed transaction instead of an authorization; this template covers the EVM rails (eip155:*) only."
