Developer-Controlled Wallets

Circle's Developer Controlled Wallets provide a robust, secure infrastructure for developers to build and manage blockchain wallets with full custody and control over private keys. Designed for Web3 applications, these wallets leverage advanced multi-party computation (MPC) technology to eliminate single points of failure and enhance security against unauthorized access or theft. The solution supports multiple EVM-compatible blockchains such as Ethereum, Polygon, and Avalanche, enabling developers to build once and deploy across chains seamlessly.

The platform emphasizes security through the use of an Entity Secret, a developer-generated cryptographic key that is encrypted and never stored by Circle, ensuring that only the developer controls wallet operations. Developers can create WalletSets, collections of wallets linked by a single cryptographic key, simplifying management across multiple blockchains. The APIs support idempotency keys to prevent duplicate transactions, and built-in monitoring tools provide detailed logs and error reporting for operational reliability.

What sets Circle's Developer Controlled Wallets apart is the combination of blockchain agnosticism, enterprise-grade security, and ease of integration with pay-as-you-go pricing and no upfront fees. The platform also offers features like gas fee sponsorship via the Circle Gas Station, improving user experience by allowing transactions without requiring users to hold native blockchain tokens. With extensive documentation, SDKs in Node.js and Python, and active community support, developers can quickly onboard and start building secure, scalable Web3 wallet solutions.
