Token mint, freeze, and blacklist permissions

Written by XAUConnect Labs · Reviewed against live product behavior · Updated August 2026

Token permissions are the difference between a bearer asset and a database the issuer still controls. Mint authority prints supply. Freeze (Solana) or blacklist/pause (EVM) stops you from selling. Admin keys that can change tax or upgrade the token can rewrite the deal after you buy.

XAUConnect Launchpad’s LaunchedToken refuses those hooks: no owner mint, no blacklist, no tax. If you are buying someone else’s token, you still have to read their contract — our factory is not their factory.

Mint

If mint exists, your percent of supply is a suggestion. Issuers sometimes “need mint for staking rewards.” That can be true and still dump you. Prefer revoked mint or a hard cap you can see on the explorer. LaunchedToken mints once in the constructor.

Freeze and blacklist

Solana freeze authority can freeze token accounts. EVM blacklists (USDT-style) can stop addresses. Either means the asset is not purely bearer. For a memecoin, freeze is usually unacceptable. For a regulated stablecoin, blacklist is part of the product — know which you are buying.

Pause and upgrade

Pausable tokens halt transfers. Upgradeable proxies can change logic. Launchpad’s LaunchedToken is not a UUPS token (the factory is upgradeable; the token bytecode you hold is not). If a random launch uses a proxy, read who the admin is.

How to check before a swap

Etherscan/BscScan/Solscan token page: holders, max supply vs total, owner functions, verified source. If source is unverified, you are guessing. Size as if you guessed wrong.

If you are the issuer

Use the honest token unless you have a regulated reason not to. Disclose any remaining admin in the Launchpad description. Traders using our guides will look. Lies last until the first holder who can read Solidity.

A two-minute explorer pass before any swap

Open the token page. Verified source? Owner functions named mint, pause, blacklist, setFee, upgradeTo? Holder concentration? On Solana, mint and freeze authorities still set? If you cannot answer, size as if the answer is hostile. XAUConnect will still quote a liquid honeypot. LaunchedToken is the exception we can describe because we shipped it — it is not a scan of the whole chain. Paste addresses anyway; permissions live on the contract, not the ticker.

Stablecoins are allowed to be bossy

USDT-style blacklists exist because issuers comply with law. A memecoin with the same hook is pretending to be a stablecoin. Know which category you are in. LaunchedToken is for the bearer-asset case. If you need freeze for a regulated product, say that in the listing — do not hide it in bytecode. Unverified source means you are guessing every one of these powers.

Frequently asked questions

Does XAUConnect scan every token for mint functions?

No. We do not audit tokens. Quotes are not safety certifications. You verify.

Is a mint function always a scam?

No. It is always a power. Powers get abused. Price that in or walk away.

What did I get if I used TokenFactory?

Fixed supply to you, ERC20Permit, creator + metadataURI, no mint/pause/blacklist/tax.

Solana freeze still on after launch — problem?

For a community token you marketed as immutable, yes. Revoke it or explain a concrete reason.
