OKX AA Smart Contract Wallet combines the advantages of External Owned Accounts (EOA) and Contract Accounts (CA), delivering enhanced security, convenience, and efficiency. It unlocks new possibilities for blockchain wallets while lowering the entry barrier for beginners.
Understanding AA Smart Contract Wallets
Before diving into OKX's solution, let’s clarify what an AA Smart Contract Wallet is.
"AA" stands for Account Abstraction, making these wallets also known as smart accounts or abstract account wallets.
In the Ethereum ecosystem, there are two primary account types:
- External Owned Accounts (EOA): Directly initiate transactions (e.g., via MetaMask or OKX Web3 Wallet). However, each action requires re-signing.
- Contract Accounts (CA): Host assets (like ERC-20 tokens) and DeFi logic but cannot initiate transactions independently.
With the 2023 deployment of ERC-4337, Ethereum introduced AA wallets, merging EOA and CA benefits:
- Programmable security (assets held by smart contracts).
- Batch transactions, gas fee delegation, and private key recovery.
- Active transaction initiation with contract-level flexibility.
