Deployment Guide

1. Environment Setup

First, create a .env file from the example:

cp .env.example .env

Edit .env with your values:

PRIVATE_KEY=your_private_key_without_0x
RPC_URL=your_rpc_url

2. Deploy Contract

Source the environment variables and run the deployment script:

source .env && forge script script/DeploySafeGuard.s.sol:DeploySafeGuard --rpc-url $RPC_URL --broadcast -vvvv

Optional Deployment Flags

• --verify: Verify contract on Etherscan
• --chain-id <id>: Specify network chain ID
• --gas-price <price>: Set specific gas price
• --legacy: For networks not supporting EIP-1559

Example: Deploy to Sepolia

source .env && forge script script/DeploySafeGuard.s.sol:DeploySafeGuard --rpc-url $RPC_URL --broadcast --chain-id 11155111 -vvvv

Contract Usage

After deployment, the SafeGuard can be:

1. Set as a guard on a Safe wallet
2. Configured with allowed target addresses for delegate calls
3. Managed by the owner to add/remove allowed targets
