MEV Ethereum Trading Bot is an Ethereum arbitrage project that combines a Solidity smart contract with external Python automation. The contract is designed to search for and execute swaps between approved Uniswap pools and routers in a single transaction. Owners can whitelist tokens and routers, configure fees and swap limits, pause execution, revoke approvals, and withdraw assets. The automation layer performs dry-run gas estimates before sending eligible transactions. It also monitors live...

Starknet Foundry is a fast development toolkit for building and testing Starknet smart contracts. It is written in Rust and built around native Cairo testing and Starknet-specific execution infrastructure. The project includes snforge for contract testing and sncast for interacting with deployed Starknet contracts from the command line. It is useful for developers who need testing, deployment, transaction handling, chain data access, and contract interaction tools in one workflow. The...

A library for secure smart contract development. Build on a solid foundation of community-vetted code. OpenZeppelin Contracts uses semantic versioning to communicate backward compatibility of its API and storage layout. To keep your system secure, you should always use the installed code as-is, and neither copy-paste it from online sources nor modify it yourself. The library is designed so that only the contracts and functions you use are deployed, so you don't need to worry about it...
