Chains & Contracts

Chains

Solana has no chain id. Never send chainId on a Solana request; the bridge routes any body that carries one to the EVM side.

CLOB_EXCHANGE

On EVM this is the ClobExchange contract: the EIP-712 verifyingContract every order and market-order signature is checked against, and the contract your collateral is deposited into. On Solana it is the settlement program that plays the same role.

The EIP-712 domain is { name: "tokenplay-clob-order-v1", version: "1", chainId, verifyingContract: CLOB_EXCHANGE } for the chain you are trading on. Signing against another chain's address, or a stale one, is refused as invalid signature.

PREDICTION_MARKET

The prediction-market contract that holds each market's outcome, resolution and payout. Trading through this API does not call it directly; it is listed so on-chain reads and explorer links resolve to the right place.
