Chain & API Support

chainID is the chain identifier used in request parameters (e.g. fromChain, toChain, chain). Chain ID is the on-chain numeric ID (used by Market & Price APIs and similar endpoints).

Notes:

Instruction Mode — same-chain swap only; ✅ means the chain can be used as fromChain / toChain for same-chain swaps.
Order Mode — ✅ means both same-chain and cross-chain are supported; Same-chain only / Cross-chain only indicate partial support (see Trading Capabilities below).
Market & Price — ✅ means HTTP market endpoints (K-lines, trades, token snapshots, etc.) are supported.
For example, seiv2 supports Market & Price only, not Instruction Mode or Order Mode.

Trading Capabilities

Applies to Instruction Mode (same-chain swap) and Order Mode (same-chain swap and cross-chain bridge). chainID is used as the fromChain and toChain request parameters.

When order value (USD) ≥ this value, the no_gas feature (pay gas with input token) is supported.

Note: When HyperCore is used as fromChain, the response data uses the signatures field instead of the txs field. For the signing method, please refer to NoGas.
