Circle has taken a big step forward for developers. Its Circle Contracts platform now runs on Arc Testnet. Builders can deploy, manage and monitor smart contracts with enterprise-grade tools. The system is designed to make smart contracts simple and fast.
Developers can use ready-to-use, 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 manages the entire contract lifecycle. Users can monitor key events and receive notifications via webhooks. Circle Contracts on Arc Testnet is free, giving developers the opportunity to experiment at no additional cost.

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