Processing

Prepare a gasless permit deposit

Experimental. Builds the EIP-712 token-authorization payload the owner signs to authorize their deposit smart account to pull amount of token from their wallet — no on-chain transfer needed. Selects ERC-3009, ERC-2612, then Permit2; validates the route, session coverage, domain, balance, and allowance before the user is asked to sign. The server chooses replay and deadline fields; submit the signature with the same fields via POST /deposits/permit. EVM source chains only; cross-chain routes only (v1).
