Circle Launches Upgrade for USDC and EURC Stablecoins, Decreases Gas Costs and Increases Security

Circle, the stablecoin issuer, has launched an upgrade for its USDC and EURC stablecoins, which includes decreased gas costs, improved support for account abstraction, and increased security for transactions on EVM blockchains. The upgrade is fully backwards-compatible and does not require any action from developers or users. The blockchain security firm Halborn audited all the code changes, and Circle plans to roll out the upgrades starting on November 9th and completing them over the next few months. The upgrades will also include improvements to checking blocklists, better resilience against forks, and a one-time rename for the EURC symbol from EUROC.
