Circle Upgraded $USDC Smart Contract

Circle launched its v2.2 upgrade for both USDC and EURC. There will be six new changes to the USDC and EURC smart contracts and they will be implemented for each supported EVM blockchain.

The new features include decreased gas costs, better support for account abstraction and increased security for transactions on EVM chains.

The upgrade is fully backward-compatible, does not introduce any breaking changes to existing integrations, and requires no action from developers or users, according to Circle.

The blockchain security firm Halborn audited all the code changes.
