description
Up-to-date documentation and code patterns for Solidity, Foundry, Hardhat, Viem, Wagmi, ethers.js, and OpenZeppelin. Use when writing smart contracts, debugging Solidity errors, setting up a Foundry project, writing Viem/Wagmi frontend code, or asking about ERC standards, gas optimization, upgradeable contracts, or any EVM development task. Triggers on: Solidity, Foundry, Hardhat, Viem, Wagmi, ethers.js, OpenZeppelin, ERC-20, ERC-721, ERC-4626, UUPS, proxy patterns, ABI, calldata, smart contract, deploy, cast, forge, anvil, or any EVM/blockchain development question.

Web3 Docs

Current patterns and references for EVM development. Covers the full stack: contracts → testing → deployment → frontend integration.

Gas Optimization Quick Rules

  1. Use calldata instead of memory for read-only function params
  2. Pack storage variables: multiple uint128 in one slot beats two separate uint256
  3. unchecked blocks for arithmetic that can't overflow (saves ~30 gas/op)
  4. immutable > constant > storage for values set once
  5. Events are cheaper than storage for historical data
  6. Batch operations: one tx touching N items beats N txs
