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)

Verify any address at runtime:

# Check contract exists (returns bytecode, or 0x if EOA)
sh scripts/rpc.sh code 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48

# Read contract identity
sh scripts/rpc.sh call 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 "symbol()(string)"

(scripts/rpc.sh is from the ethereum-networks skill)

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 (use local eRPC if running in Obol Stack)
cast code 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 --rpc-url http://erpc.erpc.svc.cluster.local/rpc/mainnet
# Fallback public RPC: https://eth.llamarpc.com

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

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