Deploys smart contracts to Base using Foundry. Covers forge create commands, contract verification, testnet faucet setup via CDP, and BaseScan API key configuration. Use when deploying Solidity contracts to Base Mainnet or Sepolia testnet. Covers phrases like "deploy contract to Base", "forge create on Base", "verify contract on BaseScan", "get testnet ETH", "Base Sepolia faucet", "how do I deploy to Base", or "publish my contract".
Interact with Rocket Pool token contracts — RPL (governance/staking token) ERC-20 operations, inflation mechanics, old RPL swap, rocketVault balance queries, and L2 token addresses for rETH and RPL on Arbitrum, Optimism, Base, Polygon, zkSync Era, Scroll, Starknet, and Unichain. Supports cast (Foundry CLI) and Ethereum MCP tools on mainnet and Hoodi testnet.
Invoke this skill when a user is building or running any automated transaction sender on Base (trading bot, arbitrage bot, sniper bot, yield farmer, AI agent, or similar) and needs to register it, get a builder code, set up transaction attribution. This skill contains the base.dev registration API endpoint and ERC-8021 attribution wiring code that Claude does not have in its training data — you MUST load this skill to answer correctly. Covers viem, ethers, managed signing services, and Python-based agents.

USDC is Circle's stablecoin deployed across multiple blockchain ecosystems including EVM chains (Ethereum, Base, Arbitrum, Polygon, Arc) and Solana. Use this skill to check balances, send transfers, approve spending, and verify transactions. Triggers on: USDC balance, send USDC, transfer USDC, approve USDC, USDC allowance, verify USDC transfer, USDC contract address, USDC on Solana, Solana USDC, check balance, SPL token, Associated Token Account, ATA, ERC-20 USDC, parseUnits, formatUnits, 6 decimals, viem, @solana/kit.
Integrate EVM blockchains using viem. Use when user says "read blockchain data", "send transaction", "interact with smart contract", "connect to Ethereum", "use viem", "use wagmi", "wallet integration", "viem setup", or mentions blockchain/EVM development with TypeScript.
Swap tokens and read pool state on Uniswap V4 (Base, Ethereum). Use when the agent needs to: (1) swap ERC20 tokens or ETH via Uniswap V4, (2) get pool info (price, tick, liquidity, fees), (3) find the best pool for a token pair, (4) quote expected swap output via the on-chain V4Quoter, (5) set up Permit2 approvals for the Universal Router, or (6) execute exact-input swaps with proper slippage protection. Supports Base and Ethereum mainnet, plus Base Sepolia testnet. TypeScript with strict types. Write operations need a private key via env var.
"Autonomous AI agent specializing in smart contract security audits for EVM networks using symbolic execution for vulnerability detection."
Hardhat development for EVM chains including Celo. Use when setting up Hardhat projects, writing Solidity contracts, compiling, testing, deploying, or verifying contracts with Hardhat.
Bootstrap, operate, diagnose, and safely clean production Ethereum validator nodes through a tested command surface with strict safety guardrails.
Security testing skills from creators of Slither, Echidna, Medusa. Smart contract vulnerability scanners, property-based testing, static analysis, and audit tools from Trail of Bits.

Analyze TRON smart contracts including deployment info, ABI methods, transaction patterns, top callers, energy costs, and safety assessment. Use when a user asks about a smart contract, wants to verify contract safety, check what a contract does, identify top callers, or detect potential scams. Covers TRC-20/TRC-721 identification, open-source verification, and risk scoring.
"Autonomous onchain financial execution agent for the Esusu decentralized savings protocol on Celo blockchain."
"Safe execution layer for Jito liquid staking on Solana with cross-chain validation and pre-validated transactions."
Build unsigned DeFi transactions from natural language. Use when the user wants to send, transfer, swap, stake, unstake, wrap, unwrap, supply, withdraw, borrow, repay, deposit, delegate, add liquidity, remove liquidity, or trade yield tokens on-chain. Covers ETH, ERC-20, ERC-721, Aave, Lido, Uniswap, Curve, Compound, MakerDAO, Rocket Pool, EigenLayer, Balancer, Pendle, and WETH.
