Coinbase Smart Wallet
Web3 / wallets security
Coinbase Smart Wallet is an account-abstracted wallet that uses passkeys for authentication, removing the requirement for users to manage and backup seed phrases. Built on ERC-4337 account abstraction standards, it allows transactions to be initiated from familiar devices like smartphones using biometric authentication (Face ID, Touch ID, or fingerprint). The wallet handles transaction fees through sponsored transactions and enables batch operations to reduce on-chain costs. It supports both Ethereum and Base networks, integrating tightly with Coinbase's ecosystem while maintaining self-custody principles and eliminating reliance on Coinbase servers to sign transactions. Example: Users can send Ethereum or use DeFi protocols directly from their iPhone using Face ID, without ever seeing or managing a 12-word seed phrase, similar to approving Apple Pay transactions. Why it matters for crypto security: By eliminating seed phrase management and leveraging biometric authentication, Coinbase Smart Wallet reduces user error and phishing vulnerability—the primary attack vectors responsible for retail cryptocurrency losses.
