Smart Account
A wallet implemented as a smart contract rather than an externally owned account (EOA). Also searched as smart contract wallet or abstract account. Smart accounts support programmable rules — multi-factor recovery, spending limits, batch calls, and sponsored gas — and are the practical face of account abstraction (often via ERC-4337) in 2026 DeFi UX.

How Smart Account works in practice
A smart account is a wallet implemented as a contract rather than a key pair. It can enforce rules a private key cannot: multiple signers, daily limits, time locks, automatic revocation.
Worked example
An account requiring two signatures for transfers above a threshold, allowing small payments with one, and permitting recovery through designated guardians after a delay.
Figures are illustrative and chosen to be checkable, not live market data.
The mistake that costs people money
The flexibility is code, and code has bugs. Guardian-based recovery also creates a social attack surface — anyone who can convince or compromise enough guardians can take the account.
