The blockchains we check
A token traps buyers differently depending on the chain it lives on. On Ethereum and the other EVM chains the danger is usually in the contract's own code; on Solana it is usually in the authorities attached to the mint.
EVM chains: the risk is in the code
On Ethereum, BNB Chain, Base and the rest, a token is a contract someone wrote. It can contain a function that blocks selling, a tax that the owner can raise to 99% after you buy, a blacklist, a pause switch, or a hidden second owner that survives a public "ownership renounced". We read those properties directly, and we check whether ownership really was given up — because if it was, most of those powers can no longer be used by anyone.
Solana: the risk is in the authorities
A Solana token is a mint with authorities attached. Whoever holds the mint authority can create more supply; whoever holds the freeze authority can freeze your token account so you cannot send it anywhere. Metadata can often be rewritten, which is how a token gets renamed into an imitation of something reputable after people have bought it. We check each of those, plus how much of the pool was burned, which is what stands between you and a pulled pool.
