TechFlow news — Circle has announced the launch of a new v2.2 upgrade for USDC and EURC, which significantly reduces gas costs, improves support for account abstraction, and further enhances transaction security on EVM blockchains.
The USDC and EURC smart contracts will undergo six new changes, implemented through a single v2.2 upgrade across each supported EVM blockchain. The upgrade is fully backward-compatible, introduces no breaking changes to existing integrations, and requires no action from developers or users.
All code changes have been audited by third-party blockchain security firm Halborn.
