Welcome to Candide
Build User-Friendly Ethereum apps with Smart Accounts
Candide provides a complete developer toolkit for Ethereum Account Abstraction, supporting ERC-4337 and EIP-7702.
Why Smart Accounts?
Smart accounts eliminate the biggest UX barriers in Web3:
- No more gas tokens: Users can pay fees in any ERC-20 token or have fees sponsored
- Simplified onboarding: Login with email, social accounts, or passkeys instead of managing seed phrases
- Enhanced security: Built-in recovery, multisig support, and spending limits
- Batch transactions: Execute multiple operations atomically in a single transaction
Core Features
Gas Abstraction
- Gasless transactions: Sponsor user fees with flexible rules and policies
- ERC-20 gas payments: Let users pay gas in any token (USDC, DAI, etc.)
Modern Authentication
- Passkey integration: Onchain WebAuthn support for biometric login
- Social login: Email and OAuth integration
Advanced Transactions
- Batch operations: Execute multiple transactions atomically
- Spending controls: Set limits and policies for subscriptions and recurring payments
Security
- Account recovery: Social Recovery or traditional recovery options
- Multi-signature: A single account controlled with multiple signatures
Smart accounts are programmable contracts, unlocking transaction capabilities impossible with traditional EOAs.
