Prevent Ethereum hashing bugs in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation.
Liquid restaking on Ethereum. Deposit ETH into ether.fi LiquidityPool to receive eETH, wrap eETH into weETH (ERC-4626 yield-bearing token) to earn staking + EigenLayer restaking rewards, unstake eETH back to ETH, check balances, and view current APY.
Ethereum token and protocol standards — ERC-20, ERC-721, ERC-1155, ERC-4337, ERC-8004, and newer standards. When to use each, how they work, key interfaces. Use when building tokens, NFTs, or choosing the right standard for a project.
Verified contract addresses for major Ethereum protocols across mainnet and L2s. Use this instead of guessing or hallucinating addresses. Includes Uniswap, Aave, Compound, Aerodrome, GMX, Pendle, Velodrome, Camelot, SyncSwap, Lido, Rocket Pool, 1inch, Permit2, MakerDAO/sDAI, EigenLayer, Across, Chainlink CCIP, Yearn V3, USDC, USDT, DAI, ENS, Safe, Chainlink, and more. Always verify addresses against a block explorer before sending transactions.
Frontend UX rules for Ethereum dApps that prevent the most common AI agent UI bugs. Mandatory patterns for onchain buttons, token approval flows, address display, USD values, RPC configuration, and pre-publish metadata. Built around Scaffold-ETH 2 but the patterns apply to any Ethereum frontend. Use when building any dApp frontend.
How an AI agent plans, builds, and deploys a complete Ethereum dApp. The three-phase build system for Scaffold-ETH 2 projects. Use when building a full application on Ethereum — from contracts to frontend to production deployment on IPFS.
Current Ethereum gas prices, transaction costs, and the real economics of building on Ethereum today. Use when estimating costs, choosing between mainnet and L2s, or when a user asks about Ethereum being expensive. Counters the
Execute DEX swaps on Solana, Ethereum, Base, or BSC. Use when buying or selling a token, getting a swap quote, or executing a trade.
Buy or sell XAUT (Tether Gold) on Ethereum using Foundry cast. Supports market orders (Uniswap V3) and limit orders (UniswapX). Triggers: buy XAUT, XAUT trade, swap USDT for XAUT, sell XAUT, swap XAUT for USDT, limit order, limit buy XAUT, limit sell XAUT, check limit order, cancel limit order, XAUT when.
Register AI agents on Ethereum mainnet using ERC-8004 (Trustless Agents). Use when the user wants to register their agent identity on-chain, create an agent profile, claim an agent NFT, set up agent reputation, or make their agent discoverable. Handles bridging ETH to mainnet, IPFS upload, and on-chain registration.
Earn yield on any Ethereum wallet on Base, Arbitrum, and Plasma. Use when a user wants passive DeFi yield on their funds. Deploys a non-custodial deterministic subaccount (Safe) linked to their EOA, enables automated yield optimization, and lets them deposit/withdraw anytime.
Deposit and withdraw from Archimedes Finance V2 protected yield vaults (ERC4626) on Ethereum mainnet. Supports WETH and crvFRAX strategies via Convex and Aura.
