Supported Tokens and Chains

Note on Chain IDs for Solana and Stellar: For non-EVM chains, the API accepts either the numeric chain ID or the lowercase chain name string:

• Solana — 900 or "solana"

• Stellar — 1500 or "stellar"

Both formats are equivalent and interchangeable in all API requests.

CCTP V2 Domain Aliases

If you're routing via Circle's CCTP V2, you can pass the CCTP domain using the cctp:<N> prefix and the API will resolve it to the canonical Rozo chain ID before validation.

Alias	Resolves to chainId	Chain
cctp:0	1	Ethereum
cctp:3	42161	Arbitrum
cctp:5	900	Solana
cctp:6	8453	Base
cctp:7	137	Polygon
cctp:27	1500	Stellar

Rules:

• The cctp: prefix is required. A bare integer (e.g. 27) is treated as a literal chainId and will return invalidChainId.

• Matching is case-insensitive and whitespace-trimmed (cctp:27, CCTP:27, Cctp:27 are all equivalent).

• cctp:25 is not aliased — domain 25 belongs to Codex, which is not currently supported.

• cctp:2 (Optimism) is not currently aliased and will be enabled separately once Optimism payout support is reviewed.
