Safe Apps Provider


This is a provider that follows common standards (e.g. EIP-1193) and can be used with various Web3 libraries (e.g. web3.js or Ethers)

$3

- Add npm package

``bash
yarn add @safe-global/safe-apps-provider

npm i @safe-global/safe-apps-provider
`

The provider can be used with the safe-apps-react-sdk and common web3 libraries.

#### With Ethers.js

- Ethers.js

`js
import React, { useMemo } from 'react';
import { ethers } from 'ethers';
import { useSafeAppsSDK } from '@safe-global/safe-apps-react-sdk';
import { SafeAppProvider } from '@safe-global/safe-apps-provider';

const App = () => {
const { sdk, safe } = useSafeAppsSDK();
const web3Provider = useMemo(() => new ethers.providers.Web3Provider(new SafeAppProvider(safe, sdk)), [sdk, safe]);

// use provider with contracts

return;
};

export default App;
`

#### With web3.js

- web3.js

`js
import React, { useMemo } from 'react';
import Web3 from 'web3';
import { useSafeAppsSDK } from '@safe-global/safe-apps-react-sdk';
import { SafeAppProvider } from '@safe-global/safe-apps-provider';

const App = () => {
const { sdk, safe } = useSafeAppsSDK();
const web3Provider = useMemo(() => new Web3(new SafeAppProvider(safe, sdk)), [sdk, safe]);

// use provider with contracts

return;
};

export default App;
``

The ethereum transaction gas limit passed to the safe-apps-provider will be treated as safeTxGas, which is an equivalent of the ethereum transaction gas limit in the Safe context. To learn more about the safe transaction gas, read here:
https://github.com/safe-global/safe-contracts/blob/c36bcab46578a442862d043e12a83fec41143dec/docs/safe_tx_gas.md

If you don't want to pass a calculation and leave it to the Safe, pass 0 as the gas limit.
