Building Account Abstraction with Safe

Safe provides a variety of Account Abstraction stacks for developers to integrate and build Account Abstraction on top of Safe.

Safe Core suites:

  1. Safe Core Account Abstraction SDK
  2. Safe Core API
  3. Safe Core Protocol

Safe Core Account Abstraction SDK​

Safe Core Account Abstraction SDK allows developers to create AA functionalities into their apps.

Protocol Kit​

Protocol Kit provides functionalities such as creating new Safe accounts, updating the configuration of existing Safes, and proposing and executing transactions.

For more details, see Guide: Integrating the Safe Core SDK and Safe Core SDK API Reference

Follow the tutorial on Safe to create a 2 of 3 multi-sig Safe and propose and execute a transaction to send some ETH out of this Safe.

Auth Kit​

Auth Kit enables users to sign in using an email address, social media account, or traditional crypto wallets like Metamask. It creates an Ethereum/Gnosis address and let users to authenticate the account using above-mentioned authentication methods.

Follow the tutorial on Safe to create a Signing Account using your email or social media account. Once authenticated, you can sign transactions and interact with any Safe Smart Accounts you own.

Onramp Kit​

Onramp Kit allows users to buy cryptocurrencies using a credit card or other payment methods. This package is provided for testing purpose only. Please use it at your own risk.

Follow the tutorial on Safe to create a React component that allows you to enter an Ethereum address and fund it using a credit card. The full code example can be found in the Safe Space repo in the WalletFund.tsx file in PR #8. We will also be using a pre-deployed server.

Relay Kit​

Relay Kit allows users to pay transaction fees (gas fees) using the native blockchain token or ERC-20 tokens. This allows you to pay gas fees using any ERC-20 token in your Safe, even if you don't have ETH.

Currently, the Relay Kit is only compatible with Gelato relay. There are two ways to use Gelato relay:

  1. Gelato 1Balance: Using prepaid deposit(via USDC on Polygon for mainnet, via gETH on Goerli for testnet) to funds the 1Balance account.With the deposit on 1Balance account, the Relay Kit can sponsors a transactions to other Safe within or on another chain.
  2. Gelato SyncFee: Allows you to execute a transaction and pay the gas fees directly with funds in your Safe, even if you don't have ETH on Ethereum or xDAI on Gnosis Chain.

Follow the tutorial on Safe to send some tokens to another address using the Relay Kit to pay for he gas fees.
