Top SchoolAugusto Lemble is a blockchain architect and founder with 11 years building decentralized systems, smart contracts, and DeFi infrastructure. He has led protocol development for DAO governance managing $100M+ in assets, shipped production smart contracts with zero critical issues, and contributed security-minded code to prominent projects like OpenZeppelin. Currently founding OpenScan, he’s implementing a trustless, RPC-only multi-chain explorer deployed on IPFS that eliminates centralized backends. His hands-on full-stack JS work spans Solidity, Hardhat, TypeScript, viem/ethers and Bun, and he’s built tooling such as a Hardhat plugin and network connectors. As a founding member of DXdao and Winding Tree and an ERC-827 contributor, he combines protocol design, distributed team leadership, and on-chain productization. Based in Mar del Plata, Argentina, he’s equally comfortable auditing complex smart contracts and shipping lightweight, censorship-resistant Web3 apps.
