Smart Contract Development
We design, build, and audit smart contracts that secure real on-chain value. From ERC-20 tokens to complex DeFi protocols — every line of code is reviewed, tested, and battle-hardened before deployment.
Legereum's smart contract team has shipped contracts securing $4M+ TVL across Ethereum, Solana, and Polygon. We write in Solidity and Rust, test with Foundry and Hardhat, and run static analysis with Slither before every deployment. Whether you need a simple token contract or a multi-sig governance system, we bring security-first engineering to every engagement.
