Candide is an open-source platform offering a comprehensive suite of tools and infrastructure for building smart wallets based on Ethereum account abstraction standards such as ERC-4337 and EIP-7702. It enables developers to upgrade traditional externally owned accounts (EOAs) to smart accounts, providing enhanced security, gas abstraction, and modular wallet features without vendor lock-in. Candide supports mobile, embedded, and standalone wallet development, making it suitable for projects aiming to improve user onboarding and wallet management in decentralized applications.

The platform includes the AbstractionKit SDK, a TypeScript toolkit that simplifies smart wallet creation and customization. It also offers a decentralized infrastructure stack including a Bundler API optimized for smart wallet transactions, a Paymaster API for gas sponsorship and stablecoin gas payments, and InstaGas for no-code gas sponsorship across multiple EVM-compatible chains. Additional modules like Safe OpenSig prevent blind signing, and Safe Account Recovery provides diverse recovery options such as social recovery and alert systems, addressing common wallet security and usability challenges.

Candide differentiates itself by focusing on a permissionless, minimalistic infrastructure maintained by a small independent team, emphasizing reliability and developer control. Its support for EIP-7702 allows upgrading existing EOAs to smart accounts, which is ideal for wallets with an existing user base. The platform’s modular plugin system enables developers to add features like passkeys, spending limits, and social recovery easily. Extensive documentation and guides help teams get started quickly, and the open-source nature encourages customization and integration with existing infrastructure or Candide’s decentralized services.
