TechFlow news — Circle has announced the expansion of USDC and EURC support across multiple Sepolia testnets, aimed at better serving developers building with Circle’s stablecoin protocol and platform services.
Key changes:
- USDC will have new Sepolia testnet addresses available for Arbitrum, Base, Ethereum, and OP.
- EURC will have a new Sepolia testnet address available on Ethereum.
- CCTP will have new Sepolia testnet addresses available for Arbitrum, Base, Ethereum, and OP. After migration, the attestation API will no longer support Goerli.
- The faucet will no longer distribute USDC and EURC on the Goerli testnet. Instead, you will be able to select and receive USDC and EURC on the Sepolia testnet.
- Circle Mint deposit addresses created on Goerli will be wiped. Sending USDC or EURC to these wiped addresses will result in permanent loss of funds within the Circle Mint sandbox. Any historical transfers and existing balances will remain unchanged.
