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.

Native Token Address

In Request and Response, fields that represent the native token contract address (such as fromContract, toContract) follow:

Default
- Request: use empty string "".
- Response: returns empty string "".
Arc
- Request: "" or 0x3600000000000000000000000000000000000000 (equivalent).
- Response: always 0x3600000000000000000000000000000000000000 (never "").
