What is a smart wallet in crypto?

A smart wallet in crypto is a wallet whose account is a smart contract rather than a plain key pair. Because the account runs code, it can follow rules its owner picks, such as requiring two approvals for big transfers or letting an app pay the fees. The term "smart contract wallet" means the same thing.

What is a smart contract wallet?

On Ethereum and similar networks there are two kinds of accounts. ethereum.org calls the ordinary kind an externally owned account, a plain key pair. Whoever has the private key has full control, and a lost key means lost funds.

A contract account holds assets too, but transactions are approved by the logic in its code. ethereum.org lists what that makes possible:

• Backup keys or trusted devices that can recover access.
• Several signatures for high-value transfers, like a multisig wallet.
• Limits on sending funds to anyone outside a trusted list.
• Paying gas for another user, or having an app pay yours.
• Bundling steps, such as an approval and a swap, into one action.

As of November 2026, ethereum.org reports more than 26 million smart wallets created. The standards behind this, ERC-4337 and EIP-7702, are explained in what account abstraction is.

What is a smart wallet on Coinbase?

Coinbase launched its Smart Wallet on June 5, 2024. The Block reported that users could create one with Face ID, a fingerprint, a Chrome profile or a YubiKey, without a recovery phrase. Developers could sponsor gas through paymasters so users paid no network fee, and it worked on eight networks at launch, including Base, Ethereum, Arbitrum and Polygon.

Coinbase's help pages now describe these accounts as a Base account inside its self-custody wallet. Sign-in is by email code or passkey, and a recovery phrase exists only if the user set one up. How passkeys fit in is covered in what a passkey wallet is.

How is a smart wallet different from a regular wallet?

The main differences, in short:

• Control. A regular wallet is one key. A smart wallet follows coded rules, which can add recovery and spending limits.
• Sign-in. A regular wallet is usually restored with a seed phrase. Many smart wallets use passkeys or other methods instead.
• Fees. A regular wallet must hold the network's gas token. A smart wallet can have fees paid by an app or in another token.
• Addresses across chains. A regular wallet has the same address on every EVM chain. A smart wallet is a contract that must be deployed on each chain, so Safe notes the address often differs between chains.

Safe warns that if a smart wallet address is shared without naming the chain, funds sent on a chain where the wallet is not deployed may be inaccessible. Always check which networks a smart wallet supports before receiving funds.

Code is also a risk of its own. A rule can only protect you if the contract behind it works as intended. Regular wallets can borrow some of these features through EIP-7702 without moving to a new address.
