Why these four metrics — and not a live on-chain scan
Every classic rug pull follows one of two mechanical patterns: the deployer pulls the liquidity pool the token trades against, leaving holders with a token that can't be sold at any real price, or the deployer mints and dumps new supply (or one whale wallet dumps a concentrated bag) faster than the market can absorb it. Both patterns leave fingerprints in data that's public before the rug happens — you just have to look it up. Liquidity-to-market-cap ratio shows how much real capital backs the token's paper valuation: a $40,000 pool against an $800,000 market cap means only 5% of the paper value could actually be extracted if everyone sold at once, and it takes a comparatively small trade to move the price violently in either direction. Top-10 holder concentration shows how much of the float sits in wallets that could dump in a single transaction — a token where ten wallets hold 70% of supply is one coordinated (or one whale's) sell order away from collapsing.
LP lock duration and renounced/burned status are binary mechanical safeguards, not sentiment: a locked or burned LP token means the pool literally cannot be withdrawn by the deployer's wallet before the lock expires, and a renounced contract means no wallet retains the admin functions (mint, blacklist, fee changes) that let a "slow rug" happen through the contract itself rather than the pool. Token age rounds out the score because the overwhelming majority of documented rug pulls happen within the first days to weeks of a launch, once initial hype has pulled in enough liquidity to make pulling it worthwhile — a token that's held liquidity and holders steady for months has already survived the highest-risk window.
This calculator deliberately does not claim to scan the blockchain, detect honeypot sell-taxes, or catch a hidden upgrade proxy — those need a bytecode scanner or a manual contract read, which a client-side calculator can't do reliably. It scores the four liquidity/ownership metrics that are publicly visible on any DEX aggregator and block explorer, the same signals behind most third-party "rug checkers", but fully transparent about the formula and computed entirely in your browser. Pair it with the Pump.fun bonding curve calculator for pre-graduation meme coins, or the smart contract cover calculator to price insuring a position instead of just scoring it.
