reentrancy-attacks

A chronological and (hopefully) complete list of reentrancy attacks to date.

snekmate

State-of-the-art, highly opinionated, hyper-optimised, and secure 🐍Vyper smart contract building blocks.

xdeployer

Hardhat plugin to deploy your smart contracts across multiple EVM chains with the same deterministic address.

createx

Factory smart contract to make easier and safer usage of the `CREATE` and `CREATE2` EVM opcodes as well as of `CREATE3`-based (i.e. without an initcode factor) contract creations.

create2deployer

Helper smart contract to make easier and safer usage of the `CREATE2` EVM opcode.

hardhat-project-template-ts

A fully-fledged Hardhat project template based on TypeScript.

malleable-signatures

This repository implements a simplified PoC that demonstrates how signature malleability attacks using compact signatures can be executed.

ecdsa-nonce-reuse-attack

This repository implements a Python function that recovers the private key from two different signatures that use the same random nonce during signature generation.

white-hat-frontrunning

White hat frontrunning script to outpace hackers and secure funds from compromised wallets.

tornado-cash-exploit

This repository implements a simplified PoC that showcases how a contract can morph. A similar approach was used as part of the governance attack on Tornado Cash in May 2023.

escrow-contract

A simple multilateral escrow smart contract for ETH and ERC-20 tokens governed by Cobie.

safe-tx-hashes-util

This Bash script calculates the Safe transaction hashes by retrieving transaction details from the Safe transaction service API and computing both the domain and message hashes using the EIP-712 standard.

raw-tx

Three scripts to ordinary generate, EIP-4844-type generate, and execute a signed raw transaction with `ethers`.

torn-detector

Detect if a contract has been deployed in the latest (or predefined) block from an address that was previously funded through Tornado.Cash.

batch-distributor

Helper smart contract for batch sending both native and ERC-20 tokens.

meth

The moment you Rust, you should look for your Mojo 🔥.

create-util

Helper smart contract to make easier and safer usage of the `CREATE` EVM opcode.

p256-verifier-vyper

P256 (a.k.a. secp256r1 elliptic curve) signature verification 🐍Vyper contract.

mnemonic-to-private-key

A JavaScript script that converts the mnemonic phrase into a wallet private key using the ethers.js library.

fork-testing-evm-compatibility

This repository implements a simple fork test on Optimism that proves that the EVM behaviour of the forked chain is not identically replicated locally.

pcaversaccio

My public profile.

tornado-cash-ether-withdrawal-decipherer

Deciphering the ether transactions in the Tornado.Cash withdrawals.

zksync-vyper-sandbox

A sandbox environment for ZKsync Era Vyper compiler testing.

ethereum-key-generation

A repository that shows how to generate a private / public key pair using web3.js or HD wallets.

chainlink-price-feed

Retrieve the ETH/USD price feed from Chainlink's oracle using Infura.

telegram-group-counter

A simple Python script to check how many Telegram groups a user is in.

configurations

Monorepo for my personal configurations.

pcaversaccio.github.io

My personal website.

porini-community-token-contract

This is Porini's ERC-20 smart contract, whose tokens can activate communities to support conservation activities and learn about blockchain technology.
