Solana Meme-Coin Risk Signals — freeze/mint Authorities and Token-2022 Traps

Solana has a different grammar

If you carry the checking habits from the Ethereum family (EVM) — "is the source code verified? has the owner renounced permissions?" — straight over to Solana, you'll be barking up the wrong tree. Solana tokens (SPL) are issued on top of a shared token program, so there is no separate source code per token; instead, the two "authorities" the issuer holds are the core of the risk.

Authority 1 — freeze authority (account-freeze power)

If the freeze authority is alive, the issuer can freeze any holder's account. A frozen account can neither transfer nor sell — the same effect as an EVM blacklist, and freezing everyone effectively makes it a honeypot. Whether this authority has been renounced (removed) is the first thing to check.

Authority 2 — mint authority (additional-minting power)

If the mint authority is alive, the issuer can mint new tokens without limit. Pouring newly minted supply into the pool dilutes the value of existing holdings and sweeps out the liquidity — the same risk as unlimited minting on EVM. A state in which both authorities are renounced is the Solana equivalent of "renouncing ownership."

Token-2022 extensions — a new generation of traps

Solana's newer token standard (Token-2022) lets you embed add-on features into a token. Useful features, but also used as scam tools:

• Transfer fee — a feature that takes a tax on every transfer. Same structure as an EVM token's trading tax, so if the rate is extreme, it becomes a trap where the more you sell the more you lose.
• Non-transferable — a token that can't be moved at all. The moment you receive it, you're locked in.
• Default state frozen — a new holder's account starts in a frozen state, and can only move once the issuer releases it. Effectively a permission-based token = honeypot-grade control.
• Closable — the issuer's power to close the mint itself. Corresponds to EVM self-destruct code.

What to be especially careful of with Solana meme coins

• Because issuance is very cheap, same-name clones and impersonation are more common — verify only by the mint address (Solana's contract address) (how to spot impersonation).
• Manipulation that inflates trading volume by running trading bots on a shallow pool is frequently observed. A ratio like a few thousand dollars of liquidity with millions of dollars of 24-hour volume is not natural.
• Early supply concentration relative to pool size — a structure where a few top wallets hold the supply is the same risk regardless of chain.

How to check

CheckCrypto supports Solana — in the scam check, select solana as the chain and paste the mint address, and it translates the freeze/mint authority status and the Token-2022 traps into risk signals on the same standard as EVM. Items that have no concept on Solana (source verification, etc.) are honestly marked "not applicable" — exactly the principle of not counting what wasn't measured as safe (evaluation method).
