eth-addresses

Verified contract addresses for major Ethereum protocols across mainnet and L2s (especially Base). Use when you need a contract address for USDC, WETH, Uniswap, Aave, Chainlink, Safe, ENS, Aerodrome, or any major protocol. Never hallucinate addresses — check here first.

gnars-cli

Use the builder-dao CLI (run locally from /Users/r4to/Script/builder-dao-tools) to interact with Gnars DAO proposals, votes, and governance data. Activate when the user asks to list proposals, get proposal details, check votes, search governance, resolve ENS names, or cast votes.

eth-concepts

Essential Ethereum mental models — incentive design, state machines, hyperstructures, randomness, and onchain terminology. Use when designing DAO features, understanding auction mechanics, explaining governance patterns, or when the user asks "how does this actually work?" for any Ethereum concept.

2026-03-13

eth-gas

Current Ethereum gas prices and transaction costs on mainnet and L2s (especially Base). Use when estimating costs for auctions, voting, or any onchain interaction. Counters outdated assumptions about Ethereum being expensive. Includes Base-specific cost data.

Contract Addresses

CRITICAL: Never hallucinate a contract address. Wrong addresses mean lost funds. If an address isn't listed here, look it up on the block explorer or the protocol's official docs before using it.
