forge-safe: Gnosis Safe batch builder

Forge Safe lets Forge users build Gnosis Safe batch transactions using Forge scripting in Solidity. Forge Safe builds a collection of encoded transactions, then sends them to the Gnosis Safe Transaction Service uses surl.

The goal of this tool is to allow users to quickly build, validate and version control complex Safe batches as code.

Inspired by ape-safe and Olymsig

Installation

forge install ind-igo/forge-safe

Usage

Steps:

1. In your .env file
   • Set CHAIN to the name of the chain your Safe is on
   • Set WALLET_TYPE with LOCAL or LEDGER depending on your wallet
2. Import BatchScript.sol into your Forge script
3. Call addToBatch() for each encoded call
4. After all encoded txs have been added, call executeBatch() with your Safe address and whether to send the transaction
5. ???
6. Profit

import {BatchScript} from "forge-safe/BatchScript.sol";

...

function run(bool send_) public {
        string memory gm = "gm";
        address greeter = 0x1111;

        bytes memory txn = abi.encodeWithSelector(
            Greeter.greet.selector,
            gm
        );
        addToBatch(greeter, 0, txn);

        executeBatch(safe, send_);
}
