On-chain USDC lottery on Base with daily drawings. Buy tickets (quick-pick or custom numbers), check the jackpot and drawing state, claim winnings, set up recurring subscriptions, and manage LP positions. Trigger on "megapot", "lottery ticket", "jackpot", "quick pick", or "did I win".

Interact with Hydrex liquidity pools on Base. Use when the user wants to lock HYDX for voting power, check voting power for gauge voting, vote on liquidity pool strategies, view pool information, check voting weights, participate in Hydrex governance, deposit single-sided liquidity into auto-managed vaults to earn Hydrex yields, claim oHYDX rewards from incentive campaigns, or exercise oHYDX into veHYDX. Uses Bankr for transaction execution.

Discover, bet on, track, and settle Hunch prediction markets in natural language. Trigger when a user wants to bet, take a position, or get odds on a crypto outcome — token market-cap milestones and flips, launchpad races (Bankr vs pump.fun volume / #1-days / launches over a cap), token head-to-head outperformance, mcap strike-ladders, and up/down price rounds. Also trigger on "what can I bet on about $TOKEN", "odds on …", "take YES/NO on …", "show my Hunch bets", "did my market resolve". Settles in USDC on Base via x402 (≤ $10 / bet); every bet returns an on-chain proof.

Decentralized git for AI agents and humans. Use when the user wants to create repositories, push code, open pull requests, review and merge PRs, manage issues, create or claim bounties, delegate tasks to other agents, register human-readable names on Base L2, or interact with the gitlawb decentralized git network. Supports cryptographic DID identities, Ed25519-signed pushes, UCAN capability delegation, libp2p networking, and 31+ MCP tools for AI agent integration. Do NOT use for GitHub, GitLab, or other centralized git hosts.

Why build on Ethereum — the AI agent angle with ERC-8004 identity, x402 payments, composability, and permissionless deployment. Corrects common misconceptions about gas costs, terminology, and network status.

Ethereum wallet creation, EOAs, smart contract wallets, Safe multisig, EIP-7702, and account abstraction. Includes AI agent key safety rules and a transaction safety pattern with human approval thresholds.

Smart contract testing with Foundry — unit tests, fuzz testing, fork testing against live state, and invariant testing. What to test, what to skip, and what LLMs commonly get wrong.

Ethereum token and protocol standards — ERC-20, ERC-721, ERC-1155, ERC-4337, ERC-8004 agent identity, EIP-7702, EIP-3009 gasless transfers, and x402 HTTP payment protocol.

Solidity vulnerabilities, defensive code patterns, and a pre-deployment audit checklist. Covers reentrancy, oracle manipulation, token decimals, SafeERC20, ERC-4626 inflation, infinite approvals, and MEV.

Pre-ship audit checklist for Ethereum dApps. Ship-blocking checks and should-fix checks covering wallet connection, button flows, contract verification, branding, RPC config, and mobile deep linking.

How an AI agent plans, builds, and deploys a complete Ethereum dApp. Three-phase build system: local fork, live testnet, production. Includes a secret safety protocol and an end-to-end agent commerce flow with ERC-8004 and x402.

How to read and query onchain data — events, The Graph, Dune, Ponder, Multicall3, and WebSocket subscriptions. Why you cannot loop through blocks and what to use instead.

Current Ethereum gas prices and real transaction costs in 2026 — counters the misconception that Ethereum is expensive. Covers mainnet vs L2 comparison, why gas dropped 95%+, and live gas trackers.

Frontend UX rules for Ethereum dApps — mandatory patterns for onchain buttons, four-state connect flows, token approval sequences, address display, USD values, and RPC configuration.

Complete build-to-production pipeline for Ethereum dApps — fork mode setup, IPFS deployment, Vercel config, ENS subdomain setup, and a full production checklist built around Scaffold-ETH 2.

DeFi legos and protocol composability — Uniswap V4 hooks, Aave flash loans, ERC-4626 vaults, Aerodrome on Base, GMX/Pendle on Arbitrum. Dominant DEX per L2 and how to combine protocols safely.

500+ item EVM smart contract audit system across 19 domains. Runs parallel specialist agents, synthesizes findings, and files GitHub issues. Separate from the security skill — this is for auditing contracts you did not write.
