Best use case

addresses is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using addresses should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# 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()`)

## 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.
