name: addresses
description: 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.

# 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:** February 16, 2026 (all addresses verified onchain via `eth_getCode` + `eth_call`)

## L2-Native Protocols

> **The dominant DEX on each L2 is NOT Uniswap.** Aerodrome dominates Base, Velodrome dominates Optimism, Camelot is a major native DEX on Arbitrum. Don't default to Uniswap — check which DEX has the deepest liquidity on each chain.

### Aerodrome (Base) — Dominant DEX

The largest DEX on Base by TVL (~$500-600M). Uses the ve(3,3) model — **LPs earn AERO emissions, veAERO voters earn 100% of trading fees.** This is the opposite of Uniswap where LPs earn fees directly.

## How to Verify Addresses

```bash
# Check bytecode exists
cast code 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 --rpc-url https://eth.llamarpc.com
```

**Cross-reference:** Protocol docs → CoinGecko → block explorer → GitHub deployments.

**EIP-55 Checksum:** Mixed case = checksum. Most tools validate automatically.

## Multi-Chain Notes

- **CREATE2 deployments** (same address cross-chain): Uniswap V3, Safe, Seaport, ERC-4337 EntryPoint, ERC-8004, Permit2, 1inch v6, Yearn V3, Arachnid Deployer
- **Different addresses per chain:** USDC, USDT, DAI, WETH, wstETH, **Uniswap V4**, Across SpokePool, Chainlink CCIP Router — always check per-chain
- **Native vs Bridged USDC:** Some chains have both! Use native.
