It’s an exciting time for the Circle Developer community. We just launched Modular Wallets, the latest upgrade to Programmable Wallets that offers modular smart contract accounts for extreme flexibility in wallet solutions. Now is also the time to integrate Circle Paymaster — the tool that enables gas fees to be paid in USDC instead of native gas tokens — and take advantage of 100% free gas fees through June 30, 2025. With these powerful tools, developers are more able than ever to create frictionless user experiences and we can’t wait to see what you build. Plus, our Developer Grants program is open once again, providing funding and support to projects shaping the future of on-chain solutions with USDC and more. If you have a groundbreaking idea, now is the time to apply — let us help bring your vision to life!

Tip of the Month
Circle Paymaster is a recently launched permissionless product that simplifies stablecoin payments by enabling users to pay gas fees directly in USDC instead of needing to hold ETH on Arbitrum or Base. This smart contract helps make transactions seamless for users and, now through June 30, 2025, gas fees are completely covered in Circle Paymaster.
Try Circle Paymaster today for free. Starting July 1, 2025, a 10% surcharge on gas fees will apply to users, but until then, gas fees are fully subsidized. Now is the perfect time to integrate Circle Paymaster and give your users a truly gasless experience.
