EOA vs. Contract Wallet

EOA Wallet：Metamask

  • Your key, your account
  • ETH is paid for gas fee

EIP4337 Contract Wallet:

  • No need to keep private key
  • Custom ways to pay for gas
  • Friendly to all users, make mass adoption possible

Problem：AA Dapp is Missing

9

EIP4337 is complex

EIP4337 has several Modules：

bundler, entrypoint, paymaster, account wallet

Learning curve is sharp for developers.

AA developer tools is not complete

Official AA sdk is in early stage.

AA sdk is hard for developer to fit in.

AA developer toolchains need to be done

For EIP4337 Standard and Infra is not ready.

So AA Dapp is still missing in the market.

EIP4337 Paymaster Gas Sponsor

  • We tested token paymaster, gasless paymaster
  • We tested account contract that support tokens.
  • We add paymaster support into sdk.

Proposing Unified Account Standard

  • Aa wallet is isolated and cannot be login 2 places
  • We propose a unified account that contains parent and son account. You can recovery son account many times, and parent is administrator
  • We further modulize the account functions.

  • Account recovery method can be customized.
  • We tested social recovery, web3auth recovery
  • We add multiple recovery method that can improve UX, and contract can be customized.
