post:
summary: Calculate rug pull probability of a contract address
description: 'Returns a rug pull probability score for a given contract address. Evaluates the contract itself, the deployer''s cross-chain behavioural history, and the behaviour of associated liquidity providers.
Use this endpoint to screen liquidity pools, token contracts, or DeFi protocol contracts before your users interact with them — or to power a rug pull alert feature in your product.
ChainAware''s rug pull model achieves **90% accuracy on new pools**, detecting preparation patterns before a documented rug event occurs.
**Subscription:** Business or Enterprise.
**Supported networks:** `ETH`, `BNB`, `BASE`, `HAQQ`.
