Solidity library for advanced fixed-point math

Tadpole Finance is a decentralized finance platform providing financial services for saving and lending. It is an opensource experimental project to create a more open lending markets, where users can make deposits and loans with any ERC20 tokens on the Ethereum network. Tadpole Finance is based on Compound Finance

DeFi Space Pirates is a platform where user can interact earning 2 tokens (Doubloons and Asteroids) and interact with a DeFi section & Nft Game section.

we Create an Aave Flash Loan arbitrage smart contract .we use the Aave v3 protocol to build a flash loan receiver smart contract. We'll then use a mock DEX contract to simulate a flash loan arbitrage.

Clone of UniswapV3

An open-source DeFi protocol with smart contracts and a web dashboard for tokenized funds, automated liquidity provisioning, and on-chain yield optimization.

A Solidity-based smart contract for a dynamic staking pool that utilizes ERC721 tokens to enable secure and variable-reward staking mechanisms.

This code defines a smart contract for a CrowdSale, where users can buy tokens with two different ERC20 tokens (TOKEN_A and TOKEN_B). The contract allows for early bonus tokens and has functionality to increase liquidity.

BuildFair is a decentralized Ethereum protocol that automates milestone-based payments and dispute resolution for transparent and fair construction contracts.

A hybrid Solidity + Python security toolkit that analyzes ERC-20 token contracts using static pattern extraction and ML-inspired scoring. Detects mint backdoors, blacklist controls, fee manipulation, trading locks, and rugpull mechanics. Outputs interpretable risk scores, labels, and structured features for deeper analysis.
