## Tool descriptions

- `get_contract_info` — Get metadata about a verified smart contract: name, compiler, classification, supported adapters, and counts of functions and events. Accepts either a curated slug (uni-eth, usdc-base, …) or chain+address.
- `get_erc20_info` — Get live state of an ERC-20 token: supply (raw + human-formatted), price, market cap, issuer, plus centralized-stablecoin admin controls (paused status, owner / masterMinter / pauser / blacklister / rescuer) when the contract exposes the…
- `get_uniswap_v3_pool` — Get live state of a Uniswap V3 pool: token pair, fee tier, current price (both directions), active liquidity, current tick, and TVL in USD (via DefiLlama token prices). Accepts slug or chain+address.

- `read_contract_state` — Read the current on-chain value of a view/pure function. Fetches from the chain (cached 60s) and returns the decoded output. Accepts slug or chain+address.
