addresses
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.
What this skill does
# 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. **Last Verified:** March 3, 2026 (all addresses verified onchain via `eth_getCode` + `eth_call` + `symbol()` + `latestAnswer()`) --- ## Stablecoins ### USDC (Circle) — Native | Network | Address | Status | |---------|---------|--------| | Mainnet | `0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48` | ✅ Verified | | Arbitrum | `0xaf88d065e77c8cC2239327C5EDb3A432268e5831` | ✅ Verified | | Optimism | `0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85` | ✅ Verified | | Base | `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` | ✅ Verified | | Polygon | `0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359` | ✅ Verified | | zkSync Era | `0x1d17CBcF0D6D143135aE902365D2E5e2A16538D4` | ✅ Verified | ### USDT (Tether) | Network | Address | Status | |---------|---------|--------| | Mainnet | `0xdAC17F958D2ee523a2206206994597C13D831ec7` | ✅ Verified | | Arbitrum | `0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9` | ✅ Verified | | Optimism | `0x94b008aA00579c1307B0EF2c499aD98a8ce58e58` | ✅ Verified | | Base | `0xfde4C96c8593536E31F229EA8f37b2ADa2699bb2` | ✅ Verified | ### DAI (MakerDAO) | Network | Address | Status | |---------|---------|--------| | Mainnet | `0x6B175474E89094C44Da98b954EedeAC495271d0F` | ✅ Verified | | Arbitrum | `0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1` | ✅ Verified | | Optimism | `0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1` | ✅ Verified | | Base | `0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb` | ✅ Verified | --- ## Wrapped ETH (WETH) | Network | Address | Status | |---------|---------|--------| | Mainnet | `0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2` | ✅ Verified | | Arbitrum | `0x82aF49447D8a07e3bd95BD0d56f35241523fBab1` | ✅ Verified | | Optimism | `0x4200000000000000000000000000000000000006` | ✅ Verified | | Base | `0x4200000000000000000000000000000000000006` | ✅ Verified | --- ## Liquid Staking ### Lido — wstETH (Wrapped stETH) | Network | Address | Status | |---------|---------|--------| | Mainnet | `0x7f39C581F595B53c5cb19bD0b3f8dA6c935E2Ca0` | ✅ Verified | | Arbitrum | `0x5979D7b546E38E414F7E9822514be443A4800529` | ✅ Verified | | Optimism | `0x1F32b1c2345538c0c6f582fCB022739c4A194Ebb` | ✅ Verified | | Base | `0xc1CBa3fCea344f92D9239c08C0568f6F2F0ee452` | ✅ Verified | ### Lido — Staking & Withdrawal | Contract | Address | Status | |----------|---------|--------| | stETH / Lido (deposit ETH here) | `0xae7ab96520DE3A18E5e111B5EaAb095312D7fE84` | ✅ Verified | | Withdrawal Queue (unstETH NFT) | `0x889edC2eDab5f40e902b864aD4d7AdE8E412F9B1` | ✅ Verified | ### Rocket Pool | Contract | Address | Status | |----------|---------|--------| | rETH Token | `0xae78736Cd615f374D3085123A210448E74Fc6393` | ✅ Verified | | Deposit Pool v1.1 | `0x2cac916b2A963Bf162f076C0a8a4a8200BCFBfb4` | ✅ Verified | --- ## DeFi Protocols ### Uniswap #### V2 (Mainnet) | Contract | Address | Status | |----------|---------|--------| | Router | `0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D` | ✅ Verified | | Factory | `0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f` | ✅ Verified | #### V3 (Mainnet) | Contract | Address | Status | |----------|---------|--------| | SwapRouter | `0xE592427A0AEce92De3Edee1F18E0157C05861564` | ✅ Verified | | SwapRouter02 | `0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45` | ✅ Verified | | Factory | `0x1F98431c8aD98523631AE4a59f267346ea31F984` | ✅ Verified | | Quoter V2 | `0x61fFE014bA17989E743c5F6cB21bF9697530B21e` | ✅ Verified | | Position Manager | `0xC36442b4a4522E871399CD717aBDD847Ab11FE88` | ✅ Verified | #### V3 Multi-Chain | Contract | Arbitrum | Optimism | Base | |----------|----------|----------|------| | SwapRouter02 | `0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45` ✅ | `0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45` ✅ | `0x2626664c2603336E57B271c5C0b26F421741e481` ✅ | | Factory | `0x1F98431c8aD98523631AE4a59f267346ea31F984` ✅ | `0x1F98431c8aD98523631AE4a59f267346ea31F984` ✅ | `0x33128a8fC17869897dcE68Ed026d694621f6FDfD` ✅ | #### V4 (Live Since January 31, 2025) ⚠️ **V4 addresses are DIFFERENT per chain** — unlike V3, they are NOT deterministic CREATE2 deploys.
