Een ERC-4337-conforme smart contract-wallet die meerdere eigenaren ondersteunt, evenals eigenaren van toegangscodes en Ethereum-adressen, met cross-chain replayability.
SOC 2 Type II-gecertificeerd · ISO 27001
Smart Wallet by Coinbase is a smart contract wallet implementation compliant with ERC-4337, designed to support advanced ownership and cross-chain functionality. It allows an unlimited number of owners, each able to transact independently without requiring approval from others. Owners can be either Ethereum addresses or passkey owners using Secp256r1 public keys, enabling flexible authentication methods including WebAuthn-based passkeys. This wallet is built to optimize calldata costs on Ethereum Layer 2 rollups by using an owner index system for signature verification.
A key feature of Smart Wallet is its cross-chain replayability. Users can sign a single user operation that can be replayed permissionlessly across multiple chains, ensuring consistent updates to ownership or wallet upgrades without needing to re-sign on each chain. This is enabled by a special function that bypasses chain ID validation for certain whitelisted operations, maintaining security while enabling seamless multi-chain management.
The wallet is deployed via the Safe Singleton Factory, which ensures deterministic addresses across hundreds of chains, simplifying multi-chain deployment. Developers can clone the repository and run tests using Forge from Foundry, with deployment facilitated by environment variables for wallet account, RPC URL, and optional Etherscan API keys. The codebase draws from established projects like Solady's ERC-4337 implementation and DaimoAccount, incorporating best practices for passkey integration and upgradeability.
Managing smart contract wallets with multiple owners and diverse authentication methods across multiple chains is complex. Users need a way to update ownership and wallet logic consistently without signing separate transactions on each chain.
Implements the Ethereum standard for account abstraction enabling advanced wallet features.
Allows certain wallet functions to be called without chain ID validation to support cross-chain replayability.
Ensures deterministic wallet addresses across 248 chains for easy multi-chain deployment.
DeFi teams can use Smart Wallet to manage funds with multiple independent owners, each able to transact without coordination.
Users can upgrade wallet logic or update owners once and replay the operation across supported chains without re-signing.
Developers can integrate WebAuthn passkey support alongside Ethereum addresses for enhanced security and usability.
