EIP-7702 Clean Delegation

A command-line tool to automatically revoke EIP-7702 delegations on Ethereum.

What is EIP-7702?

EIP-7702 is an Ethereum standard that allows EOAs to temporarily delegate their authority to smart contract code. This tool helps you revoke these delegations when no longer needed.

Prerequisites

• Bun runtime (v1.0.0 or higher)
• An Ethereum RPC provider (QuickNode, Alchemy, Infura, etc.)
• Private key(s) for the account(s) you want to use

Installation

1. Install Bun Runtime

If you don't have Bun installed:

# macOS/Linux/WSL
curl -fsSL https://bun.sh/install | bash

# Windows (PowerShell)
powershell -c "irm bun.sh/install.ps1 | iex"

2. Clone and Setup

# Clone the repository
git clone https://github.com/codeesura/eip7702-clean-delegation.git
cd eip7702-clean-delegation

# Install dependencies
bun install

Configuration

1. Create Environment File

Copy the example environment file:

cp .env.example .env

2. Configure Your Settings

Open .env in your favorite editor and add your configuration:

# REQUIRED: Your Ethereum RPC Provider URL
# Get one free from: https://quicknode.com, https://alchemy.com, or https://infura.io
PROVIDER_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR-API-KEY

# REQUIRED: Private key of the account with delegations to revoke
# Format: 0x followed by 64 hexadecimal characters
DELEGATOR_PRIVATE_KEY=0x12345....

# OPTIONAL: Sponsor account private key (pays gas fees instead of delegator)
# Useful for accounts with no ETH balance
SPONSOR_PRIVATE_KEY=0x12345....

# OPTIONAL: Chain ID (default: 1 for Ethereum mainnet)
# Common values: 1 (mainnet), 11155111 (Sepolia), 17000 (Holesky)
CHAIN_ID=1

• Never commit .env file to version control
• Use test accounts first to verify functionality
• Consider using hardware wallet derived keys for production
