We’ve been on a mission to showcase our collaboration with developers, prospective partners, and retail customers.
Circle joined Stripe Sessions last month in San Francisco, where fintechs shared their excitement about integrating stablecoins into their business models. Our Superteam Vietnam workshops — which let developers connect, build with Circle APIs and SDKs, and explore real-world USDC use cases — just wrapped up, and the Solana Summit in Da Nang, Vietnam kicks off today.
And we’re not slowing down. We’ve teamed up with MetaMask and Li.Fi to host a hackathon that’ll push the MetaMask Card ecosystem forward and put USDC to work in digital payments. Sign up now, and take your shot at the $40,000 prize pool along with the chance to record a professionally produced project demo at Circle Dev Summit Cannes.

Tip of the Month
Circle Paymaster now supports ERC-4337 v0.8. This update includes support for EIP-7702, enabling Externally Owned Accounts (EOAs) to access smart contract features like gas sponsorship. Now, users can pay gas fees directly from their USDC balance without deploying a custom wallet. Try out the sample app on Replit.
Integration
We’ve expanded support for OP Mainnet and Base across Circle’s Developer Services. These networks are fully integrated with Circle Modular Wallets, contract deployment, gasless transactions, and more.
Create your Circle Modular Wallet and send your first gasless transaction. Get started here.
import { baseSepolia, optimismSepolia } from 'viem/chains'
import { toModularTransport, toCircleSmartAccount } from '@circle-fin/modular-wallets-core'
import { createPublicClient } from 'viem'
const clientUrl = import.meta.env.VITE_CLIENT_URL as string
const modularTransport = toModularTransport(
clientUrl + '/baseSepolia',
clientKey,
)
const client = createPublicClient({
chain: baseSepolia,
transport: modularTransport,
})
