Signals

What BaseGuard checks

lock

LP Lock Status

Checks whether liquidity is locked in a verified locker contract. Unlocked LP means the deployer can pull liquidity at any time — the clearest rug signal on EVM chains.

LOCKED UNLOCKED PARTIAL

person_search

Deployer History

Traces the deployer wallet across Base, Ethereum, and Arbitrum. Known-safe deployers (Coinbase, Uniswap, major protocols) are flagged immediately. Serial ruggers identified by history.

KNOWN SAFE FLAGGED UNKNOWN

group

Holder Concentration

Analyses the top holder distribution. Extreme concentration in one or two wallets means a coordinated dump can collapse the price instantly — regardless of other signals.

DISTRIBUTED CONCENTRATED

How it works

Token to verdict in under 1s

01

Pass the contract address

Send any EVM token address and chain ID in a single POST request. x402 handles the $0.02 payment automatically — no auth headers needed.

02

BaseGuard analyses on-chain

LP lock status, deployer wallet history, and holder distribution checked in parallel across Base, Ethereum, and Arbitrum. Cached tokens return in under 1ms.

03

Act on the verdict

SAFE / CAUTION / DANGER returned with confidence level and per-signal breakdown. Gate your trade, alert your users, or block the transaction — your logic, our data.
