Smart Accounts
Self-custody accounts with security policy enforced on-chain.
What it does
A smart account is a wallet that is also a contract. Built on ERC-4337 with ERC-7579 modules, it lets people sign in with a passkey, avoid paying gas directly because fees can be sponsored, and recover access without a seed phrase, while security policy lives in the account itself: limits, verified payees and second-factor checks are enforced before any transaction executes. It is designed so that no key held by the operator can move a user's funds on its own. It is the account layer of SBX AURA.
Powers
How it works
Smart Accounts are where people hold value. Address Intelligence runs inside their policy, MPC Custody covers institutional key management, and the Token Standards Library supplies the audited ERC-4337 and ERC-7579 base.
