CCTP Supported Chains and Domains

CCTP Supported Blockchains

CCTP is available on the following blockchains, where USDC is natively issued, providing Standard Transfer, Fast Transfer , and Hooks capabilities.

Blockchain (*)	Source (Standard transfer)	Source (**) (Fast transfer)	Destination
Arc Testnet	✅	❌	✅
Arbitrum	✅	✅	✅
Avalanche	✅	❌	✅
Base	✅	✅	✅
BNB Smart Chain (USYC only)	✅	✅	✅
Codex	✅	✅	✅
Ethereum	✅	✅	✅
HyperEVM	✅	❌	✅
Ink	✅	✅	✅
Linea	✅	✅	✅
Monad	✅	❌	✅
OP Mainnet	✅	✅	✅
Plume	✅	✅	✅
Polygon PoS	✅	❌	✅
Sei	✅	❌	✅
Solana	✅	✅	✅
Sonic	✅	❌	✅
Starknet Testnet	✅	✅	✅

World Chain	✅	✅	✅
XDC	✅	❌	✅

• (*) If a mainnet is listed, its official testnet is also supported.
• (**) Fast transfer is available for source chains only when it provides a meaningful speed improvement over standard burn attestation times. For those chains, a standard transfer is as efficient as a fast transfer.

CCTP Supported Domains

A domain is a Circle-issued identifier for a blockchain where CCTP contracts are deployed. Domains don’t map to any existing public chain ID.

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
