Web3, smart contracts, and specialized crypto tools.
LayerZero V2 cross-chain messaging — OApp framework, OFT (Omnichain Fungible Token), DVN configuration, executor setup, message options, and cross-chain deployment patterns. Covers lz-oapp contracts, EndpointV2 interface, message lifecycle, and security configuration across Ethereum, Arbitrum, Base, Optimism, and Polygon.
Arbitrum Stylus development — write smart contracts in Rust, C, and C++ compiled to WASM. Covers Stylus SDK, storage patterns, ABI export, deployment, testing, and Solidity interop.
Hardhat Solidity development framework — project setup, plugin ecosystem, testing with Mocha/Chai, deployment with Hardhat Ignition, contract verification, Hardhat Network forking, TypeScript configuration, and custom task creation. Works on any EVM chain.
ethers.js v6 TypeScript/JavaScript Ethereum library — Provider, Signer, Contract interaction, ABI encoding/decoding, event filters, ENS resolution, and BigNumber-to-bigint migration from v5. Covers JsonRpcProvider, BrowserProvider, Wallet, ContractFactory, and typed contract interfaces.
Core Ethereum development concepts including gas mechanics, transaction types, storage layout, ABI encoding, and EVM execution model. Use as a reference when building on Ethereum or EVM chains.
Ethereum Improvement Proposals and ERC standards reference — ERC-20, ERC-721, ERC-1155, ERC-4626, ERC-2981, EIP-712, EIP-1559, EIP-2612 (Permit), EIP-4337 (Account Abstraction), EIP-4844 (Proto-Danksharding), EIP-7702 (EOA Delegation), ERC-8004 (Agent Identity). Quick lookup, interface signatures, and implementation patterns.
Semgrep rules for smart contract security — custom pattern matching, taint tracking, community rulesets, autofix rules, and CI/CD integration. Write targeted detection rules for Solidity vulnerabilities that static analyzers miss.
EigenLayer restaking protocol — stake ETH and LSTs to secure AVSs (Actively Validated Services), operator registration and delegation, reward claiming, and slashing conditions. Covers StrategyManager, DelegationManager, AVSDirectory, and the restaking lifecycle on Ethereum mainnet.
Wormhole cross-chain messaging and token transfers — NTT (Native Token Transfers) framework, VAA (Verified Action Approvals), guardian network, automatic and manual relayers, Wormhole Queries for cross-chain reads, and Standard Relayer integration. Covers Wormhole SDK, contract interfaces, and deployment across Ethereum, Solana, Arbitrum, Base, and Optimism.
Verified contract addresses for major EVM protocols across Ethereum, Arbitrum, Optimism, Base, and Polygon. Covers tokens, DEXes, lending, bridges, and infrastructure. Use as a reference when building integrations — every address is checksummed and should be verified onchain before use in production.
Tenderly blockchain DevOps platform — transaction simulation API, fork environments for testing, Alerts and Webhooks for monitoring, Web3 Actions (serverless functions), contract verification, Gas Profiler, and Transaction Debugger. Covers REST API integration and Tenderly SDK.
Compound V3 (Comet) lending protocol — supply, borrow, repay, withdraw, liquidation, governance proposals, and cross-chain Comet deployments. Covers Comet interface (single-asset borrowing), Configurator, Bulker for batched operations, and COMP governance across Ethereum, Arbitrum, Base, Optimism, and Polygon.
Complete guide for Squads Protocol - Solana's leading smart account and multisig infrastructure. Covers Squads V4 Multisig for team treasury management, Smart Account Program for account abstraction and programmable wallets, and Grid for stablecoin rails and fintech infrastructure.
Comprehensive Solidity security patterns, vulnerability prevention, and audit preparation. Covers reentrancy, access control, token decimals, oracle manipulation, vault inflation, proxy safety, EIP-712 signatures, MEV protection, and pre-deploy checklists. Every pattern includes wrong vs correct code.
Security audit of Solidity code while you develop. Trigger on "audit", "check this contract", "review for security". Modes - default (full repo), DEEP (+ adversarial reasoning), or a specific filename.
Uniswap V3 and V4 DEX integration — exact input/output swaps via SwapRouter02 and UniversalRouter, concentrated liquidity positions via NonfungiblePositionManager, V4 hook architecture with PoolManager singleton, pool state reads (slot0, ticks, TWAP), and Permit2 token approvals. Covers Ethereum, Arbitrum, Base, and Optimism.
