Supported blockchains
CCTP provides Standard Transfer, Fast Transfer, Hooks, and Forwarding Service capabilities on the following blockchains. All chains listed below are supported as destination chains.Fast Transfer availability:Fast Transfer is available for source
chains only when it provides a meaningful speed improvement over standard burn
attestation times. For blockchains where standard attestation is already fast,
Fast Transfer is not necessary. These chains are marked N/A in the Source
(Fast transfer) column below.
On Stellar, USDC precision and address encoding differ from other CCTP-supported
blockchains. For inbound transfers, use
CctpForwarder
so funds reach the correct recipient. See
CCTP on Stellar.Forwarding Service support:The column labeled “Forwarding Service” indicates whether the blockchain is
available as a destination chain for the
Circle Forwarding Service.Testnet support:If a mainnet is listed, its official testnet is also supported. For example,
Ethereum includes both Ethereum Mainnet and Ethereum Sepolia.
Domain identifiers
A domain is a Circle-issued identifier for a blockchain where CCTP contracts are deployed. Domain identifiers don’t map to existing public chain IDs. Use domain identifiers when calling CCTP contracts and API endpoints:Supported tokens
Not all domains support the same tokens:- USDC: Supported on all CCTP domains except BNB Smart Chain
- USYC: Supported only on Ethereum and BNB Smart Chain
