Now Available: USDC on Unichain and Circle’s Developer Tools

We’re excited to announce that USDC is now available on Unichain mainnet along with a suite of Circle’s developer tools. Starting today, developers building on Unichain now have access to USDC, CCTP (Cross-Chain Transfer Protocol), and Programmable Wallets to build secure and scalable onchain apps that can easily onboard users across blockchains.

USDC: Powering Liquidity and DeFi Innovation on Unichain

USDC on Unichain is natively accessible to developers and their users – no bridging required. Circle Mint and its APIs now fully support USDC on Unichain, making it easy for qualified businesses to access USDC liquidity and benefit from Unichain’s fast and low-cost network.¹

As the world’s largest regulated dollar stablecoin², USDC enhances user confidence and settlement for digital asset trading use cases. USDC forms many of the most liquid trading pairs on the Uniswap app across leading blockchains, including Arbitrum, Base, Ethereum, OP Mainnet, Polygon PoS, and more. Unichain aims to further enhance trading performance with USDC and become the ultimate hub for DeFi activity.

The Circle Platform: A Complete Suite for Builders 

This launch goes beyond USDC—it’s about equipping developers on Unichain with a robust platform to build next-generation onchain apps:

1. USDC issued by Circle

• Token Name: USDC
• Token Symbol: USDC
• Mainnet Address: 0x078D782b760474a361dDA0AF3839290b0EF57AD6
• Testnet Address: 0x31d0220469e10c4E71834a79b1f276d740d3768F

Developers can start to experiment with funds flows in their Unichain apps today by getting free testnet USDC from Circle’s Faucet.

2. CCTP (Cross-Chain Transfer Protocol)

CCTP enables developers to design cross-chain experiences by connecting their Unichain apps to additional blockchains including Arbitrum, Base, Ethereum, Solana, and more. With no need to lock up liquidity, CCTP provides a highly secure and capital-efficient way to transact with USDC across blockchains. 

3. Programmable Wallets

Programmable Wallets offers developers flexible and secure wallet infrastructure, allowing easy creation of in-app wallets on Unichain that cater to global users and streamline DeFi trading and swapping. With rapid deployment using REST APIs, customizable custody models, integrated compliance tools to help meet regulatory requirements, and Gas Station to sponsor network fees, businesses can easily onboard users while delivering a secure and familiar UX.

4. Smart Contract Platform (coming soon)

Smart Contract Platform will offer Unichain developers a simpler way to create, deploy, and manage smart contracts. With end-to-end tooling and a curated library of security-audited templates, businesses can save cost and get to market fast without needing to write Solidity. Tokenize real-world assets, integrate with DeFi apps, and enhance customer engagement with NFTs and loyalty programs.
