Blockchain Hacks

⚠️ Disclaimer: This repository is strictly for educational and research purposes. It contains Proof of Concept (PoC) implementations of historical blockchain hacks to help developers and auditors understand smart contract security.

This repository contains proof of concept implementations of historical blockchain hacks. It uses Foundry for mainnet fork testing to simulate attacks in a real-world environment.

1. Prerequisites

Ensure you have Foundry installed. If not, run:

curl -L https://foundry.paradigm.xyz | bash
foundryup

2. Setup

1. Clone the repository:

git clone https://github.com/yAudit/blockchain_hacks
cd blockchain_hacks

2. Install dependencies:

forge install

3. Configure RPC Endpoint: Open foundry.toml in the root directory and add your Ethereum mainnet RPC URL (e.g., from Alchemy or Infura) under the [rpc_endpoints] section:

[rpc_endpoints]
mainnet = "https://eth-mainnet.g.alchemy.com/v2/YOUR_API_KEY"

3. Exploit Reports

#	Project	Test File	Hacked Date
1	Balancer V2	test/BalancerV2.t.sol	November 03, 2025

4. Running the Code

Once your RPC is configured, you can run the exploit simulation:

# Run all tests
forge test

# Run the Balancer V2 exploit
forge test --match-path test/BalancerV2.t.sol

# Run with traces to see the step-by-step exploit logic
forge test --match-path test/BalancerV2.t.sol -vvvv
