Ethereum and BNB Chain token checker: what to check before buying

Tokens are contracts, so the checks read the contract

Tokens on Ethereum (ERC-20) and BNB Chain (BEP-20) are smart contracts. Whatever powers the creator wrote into the contract can still be used later: minting new supply, freezing transfers, blacklisting addresses or charging a fee on every trade. A check of an EVM token is therefore a check of what the contract allows and who controls the liquidity.

QZMO uses security data from GoPlus for the contract checks and DexScreener for markets and price. The tiles have the same names as on Solana: Mint, Freeze, Liquidity, Tax, Creator and Connected. The Robinhood Chain guide explains each tile in detail; the meaning is the same on Ethereum and BNB Chain.

The same address can exist on several chains

An EVM address looks identical on every chain, and the same token contract is sometimes deployed on more than one. When you paste an address, QZMO looks up where it trades, picks the chain with the most liquidity and shows the result for that chain. If the token trades on several of the supported chains, “Also on” buttons under the token name let you switch.

Check the chain shown next to the token name before you rely on a result. A token with the same name on another chain is a different contract.

What differs by chain

• Explorer: addresses open on Etherscan (Ethereum) or BscScan (BNB Chain).
• Smart Money: available on both. It evaluates the largest holders and the earliest buyers with Zerion profit and loss data.
• Funding trace: available on both. On BNB Chain the inflow and outflow lists cover roughly the last two months of activity; the first funder is looked up separately and can be older.
• Connected wallets: not available on either chain. The tile defaults to “None” and is not a real check.
• Concentrated-liquidity pools (v3 and v4 style) show “—” instead of a lock percentage in the markets table, because a lock percentage does not describe them well.

Limits to keep in mind

• Contracts can be upgradeable, and owners can change settings after you checked.
• Data providers can lag or have no data for a new token. When the liquidity lock reads “N/A”, no lock data was available; that is not the same as “Not locked”.
• Honeypot and blacklist flags feed the risk score and have no tile of their own.
