**_It was announced that EIP-4337 has been deployed on the Ethereum mainnet at WalletCon, giving us a new token standard, ERC-4337._**

ERC-4337 introduces Ethereum account abstraction, which we will call Smart Accounts or smart contract wallets. You can think of them as smart contracts for your wallet.

*   One of the coolest features is wallet recovery No more struggling to remember your seed phrases — now you can nominate trusted friends or family members to help you recover your account. You can also use your smartphone’s biometrics for 2FA!
    
*   Another big feature is bundling This allows multiple transactions to be bundled together and completed with one signature.
    
*   Next, we have sponsored transactions As the name suggests, someone else can pay the gas/transaction fees for you. This is going to be huge for adoption, especially for onboarding non-crypto natives.
    
*   Pre-approvals are another feature You can pre-approve transactions for a certain period of time, within a certain application. It’s like signing one transaction to last for a while and then being able to play or interact with the blockchain to your heart’s content.
    
*   Lastly, we have subscriptions Subscription models have always been tricky on ETH, but ERC-4337 will allow for processing automated payments to be natively integrated in a streamlined fashion. We even had payment giant Visa discussing this last year.
