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

# 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.

✅ All addresses verified onchain via eth_getCode + eth_call — February 16, 2026. Bytecode confirmed present, identity confirmed via symbol/name/cross-reference calls. Does NOT guarantee safety — always verify on 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.

How to Verify Addresses

# 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.
