Training program

Module 1Advanced Solidity: expert syntax, libraries and patterns (Hardhat, Foundry)

Dive into inline assemblies, custom errors and optimized storage, code reusable libraries to reduce gas by 40%, test via Foundry with intensive fuzzing, analyze patterns like diamond proxy on real Uniswap V3 cases, produce a deliverable: gas-efficient library deployed on testnet.

Module 2Gas Optimization and Scalability: Layer 2, rollups (Optimism, Arbitrum)

Master EIP-4844 blobs and ERC-4337 account abstraction, refactor contracts for zk-rollups, simulate gas wars with Hardhat exercises, integrate blobs for cheap data, measure gains up to 90% on Polygon, deliverable: optimized contract deployed on Sepolia with performance report.

Module 3Expert Security: audits, reentrancy guards, formal methods (Slither, Echidna)

Detect sandwich attacks and MEV via Slither scans, implement emergency pauses and Gnosis multisig, fuzz with Echidna on 1000+ scenarios, audit protocols like Aave flashloans, simulate Ronin hacks (625M$ lost), deliverable: full DeFi contract audit with fixes.

Module 4Advanced Projects: DeFi, DAO, NFT (Chainlink, OpenZeppelin Upgrades)

Build yield farm with Chainlink oracles, deploy upgradable DAO via OpenZeppelin, integrate EIP-2612 permits for gasless approvals, test end-to-end on Anvil mainnet fork, challenge on NFT fractional ownership, deliverable: complete DeFi protocol with governance, deployed and pitched in groups.
