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()`)
