AA Smart Contract Accounts (Account Abstraction) merge the advantages of traditional externally owned accounts (EOAs) and contract accounts (CAs) into a single, programmable solution. By ensuring assets are held solely by smart contracts, these accounts enable advanced features like batch transactions, gas sponsorship, and key recovery—streamlining and simplifying on-chain interactions.
In blockchain networks, two primary account types exist: externally owned accounts (EOAs) and contract accounts (CAs). EOAs allow users to send transactions and interact with smart contracts through wallets like MetaMask or OKX Web3 Wallet, though each action requires individual signing. CAs, which host assets like ERC-20 tokens and DeFi logic, cannot initiate transactions independently.
AA Smart Contract Wallets combine the proactive transaction capability of EOAs with the security and flexibility of CAs. This fusion enables programmable features such as batch operations, gas fee abstraction, and secure key recovery, all while maintaining low trust requirements and high scalability.
How to Create an OKX AA Smart Contract Wallet
OKX Web3 Wallet supports multiple wallet types, including mnemonic, private key, keyless, and hardware wallets. Users can add an AA Smart Contract Account to any existing account, with each AA account generated from a standard account to manage on-chain behavior and recovery.
To get started, open the OKX app and log in. Navigate to the Web3 Wallet section from the homepage and select "Create Wallet." Choose your verification method, set a password or enable biometric authentication, and confirm to create the wallet. Existing users can select "Import Wallet" and restore using a mnemonic phrase or private key.
After creation, back up your wallet before proceeding. From the wallet homepage, click the dropdown menu, select "Add Account," and choose "Smart Account" to create your AA Smart Contract Account.
Note: Keyless and private key wallets support only one AA account each, while mnemonic wallets allow multiple AA accounts corresponding to each sub-account (e.g., Wallet D - Account 01 links to Wallet D - Smart 01). Additionally, users must have an existing standard wallet before creating an AA account.
Importing an Existing AA Smart Contract Account
If you’ve previously created an AA account on OKX Web3 Wallet, import it by restoring the associated wallet via keyless recovery, cloud backup, mnemonic phrase, or private key.
For AA accounts based on keyless or private key wallets—which support only one AA account each—importing the main wallet automatically displays the AA account if it holds a balance.
Mnemonic-based wallets, however, can have multiple sub-accounts and corresponding AA accounts. Importing a mnemonic phrase only shows the first sub-account initially. To access a specific AA account (e.g., Smart-03 under Account-03), recreate the sub-accounts and their AA counterparts step by step.
Common Use Cases for AA Smart Contract Wallets
AA Smart Contract Wallets enhance experiences across activities like token transfers, trading, mining, and DApp interactions. Below are key scenarios where their advantages shine.
Token Transfers
Sending tokens with an AA account mirrors standard wallets until gas payment. Select the token, network, recipient, and amount. If the wallet lacks the native gas token, choose any supported token for gas payment via the "Pay with" option. Eligible users (e.g., those with project or wallet subsidies) may see gas fees waived entirely.
DEX One-Click Swaps
AA accounts enable seamless token swaps on OKX DEX by combining approval and exchange into a single transaction. This reduces steps and improves the on-chain trading experience.
Bulk NFT Approvals
When listing multiple NFTs, users can authorize several collections simultaneously with one click. As more NFT platforms adopt AA support, this will extend to multi-platform approvals in a single action.
DeFi One-Click Mining
Similar to DEX swaps, AA accounts consolidate complex DeFi operations—such as investing or portfolio rebalancing—into streamlined one-click processes.
Frequently Asked Questions
What is account abstraction?
Account abstraction merges externally owned and contract accounts into a programmable smart contract wallet. It enables features like batch transactions, gas sponsorship, and key recovery while maintaining security.
Can I create multiple AA accounts?
Yes, but it depends on your wallet type. Mnemonic wallets support multiple AA accounts (one per sub-account), while keyless and private key wallets allow only one AA account each.
How do I pay gas fees with an AA account?
If the wallet lacks the native gas token, select any supported token for payment during transaction confirmation. Some users may qualify for fully subsidized gas fees.
Is key recovery possible with AA wallets?
Yes, AA wallets support secure key recovery mechanisms through their programmable design, enhancing usability without compromising security.
Which networks support AA Smart Contract Wallets?
OKX AA wallets primarily support Ethereum and compatible EVM chains. Always check network availability within the OKX Web3 Wallet interface.
Can I use AA accounts with any DApp?
While OKX continues to expand integration, not all DApps fully support AA accounts yet. Popular platforms like OKX DEX and leading NFT marketplaces are increasingly adopting the standard.
