Frequently Asked Questions
What is a token safety checker?
A token safety checker is a tool that analyses a crypto token's smart contract and on-chain activity to detect scams, vulnerabilities, and hidden risks before you trade. Guava's token safety checker runs 30+ automated checks across honeypot simulation, taxes, liquidity, holder concentration, contract verification, and more — all in under 2 seconds.
Is the token safety checker free?
Yes — token safety analysis is completely free on Guava. You can run a check on this page without signing up. Free accounts get 10 analyses per day. No credit card required.
Which blockchains does the token safety checker support?
Guava checks 31 chains including Ethereum, BSC, Base, Arbitrum, Optimism, Polygon, Avalanche, Blast, zkSync, Linea, Scroll, Mantle, and other EVM networks using GoPlus Security, plus Solana via RugCheck.
What does a token safety analysis include?
Each analysis runs 30+ security checks: honeypot trade simulation, buy/sell tax detection, contract source verification, proxy/upgradeable contract detection, mint authority, owner privileges, blacklist and pause functions, liquidity lock status, top holder concentration, deployer reputation, and more. You get a clear risk score from 0 to 100 with a colour-coded risk level.
How is a token safety checker different from a honeypot detector?
A honeypot detector focuses specifically on detecting honeypot scams — contracts that let you buy but block selling. A token safety checker is broader: it covers honeypots plus taxes, liquidity, holder concentration, contract verification, proxy contracts, mint authority, and dozens of other risk vectors. Guava's token safety checker includes honeypot detection as one of its 30+ checks.
What is contract source verification and why does it matter?
Contract source verification confirms that a token's deployed bytecode matches published, human-readable source code (e.g. on Etherscan or BscScan). Unverified contracts hide their logic, making it impossible to audit for honeypots, hidden taxes, or rug-pull functions. Guava flags unverified contracts as a major red flag.
What is a proxy contract and is it dangerous?
A proxy (or upgradeable) contract lets the owner change the token's logic after deployment. This means a token that looks safe today could be upgraded tomorrow to add a honeypot, mint function, or high sell tax. Guava detects proxy contracts and flags them so you know the rules can change.
What is mint authority and why should I check it?
Mint authority is the power to create new tokens, increasing the total supply and diluting the value of existing holders. On Solana, tokens with an active mint authority can be inflated at will by the authority holder. Guava checks both EVM mint functions and Solana mint/freeze authority and warns you when they are not renounced.
How accurate is the token security check?
Guava runs 30+ security checks per token using GoPlus Security and RugCheck — the same engines trusted by major crypto exchanges and DeFi protocols. While no tool can guarantee 100% safety, our checks catch the vast majority of known scam patterns including honeypots, rug pulls, hidden taxes, and malicious contract functions.
What does a 'Critical' risk score mean?
A Critical score (50+) means multiple severe red flags were detected — such as a confirmed honeypot, unlocked liquidity, or an unverified contract with blacklist functions. You should avoid trading this token entirely.
