EIP-712 envelope preview

The SoDEX REST v1 spec signs orders as EIP-712 typed-data. This page shows the exact payload, canonical serialization, payloadHash, and typed-data structure that would be signed for any intent the agent layer produces. No wallet needed to inspect.

How the envelope reaches SoDEX

Agents produce an intent: {ticker, verdict, score, rationale}
ExecutionAgent maps it to a SoDEX payload: {action, symbol, side, type, qty, price, reduceOnly, nonce}
Payload is canonicalized (alpha-sorted JSON, no whitespace) for determinism
Canonical bytes are keccak256-hashed → payloadHash
Wallet signs the EIP-712 typed-data {payloadHash, nonce} with the SoDEX domain
Resulting signature is 0x01-prefixed (SoDEX wraps EIP-712 with a version byte)
POST to testnet-api.sodex.com/v1/order/new with headers X-API-Key: <signer addr>, X-Sign: <0x01-prefixed sig>, X-Nonce: <ms nonce>, body is the original payload
