Onchain accounts, often called “wallets”, are the starting point for any onchain interaction. Unlike traditional accounts that store credentials in a database, onchain accounts authenticate and authorize transactions on the public network with credentials held by the user. The original onchain accounts (EOA’s) use private keys backed up by a sequence of 24 random words. Recently, with the introduction of modern accounts like Smart Wallet, the credentials are Passkeys which provide improved security and recoverability. This sub-section covers these two main wallet types, the differences in user experience and security, and how Base’s Smart Wallet SDK makes them easier to integrate.

​
What’s Different?

Every onchain action requires an account (a wallet) to sign transactions. Onchain accounts can hold funds and also authorize transactions on a blockchain.

​
Types of Onchain Accounts

​
Externally Owned Accounts (EOAs)

Traditional Model: Private key + seed phrase model (e.g., MetaMask, Rabby, Ledger)

User Experience: Commonly used today but can be cumbersome or risky for new users

Capabilities: Holds digital assets but has no account level logic. Required for deploying smart contracts.

​
Smart Wallets

Modern Approach: Modern accounts with their own logic enabling improved security, recoverability, and functionality.

Enhanced Features: Built-in recovery features, passkey authentication, and improved onboarding experience for users

Advanced Permissions: Can include features like “SpendPermissions” for fine-grained security and improved user experience
