Circle has made a big move for developers. Its Circle Contracts platform now works on Arc Testnet. Builders can deploy, manage, and monitor smart contracts with enterprise-level tools. The system is designed to make smart contracts simple and fast.
Developers can use ready-made, security-audited templates to tokenize assets in minutes. They can create ERC-20, ERC-721, and ERC-1155 tokens for lending, trading, rewards, and payments. A single console handles the full lifecycle of contracts. Users can monitor key events and get notifications through webhooks. Circle Contracts on Arc Testnet is free, giving developers room to experiment without extra costs.

Circle Wallets and Expanded Access
Alongside smart contracts, Circle Wallets is now live on Arc Testnet. Builders can access a full range of wallet infrastructure that is flexible, embeddable, secure, and multichain. This allows faster development without running custom infrastructure or learning complex coding languages like Solidity.
