Each order has a unique reference key; the server confirms the payment on-chain and shows the report. Payments go to the public address Bx9Fq6sNBR6fhE5Auw8A9N6mwHLERrhYWcC8gLGtQAut. No wallet connection and no sign-up.

## Data sources
Solana mainnet RPC, Metaplex Token Metadata and the public DexScreener API. Reports are automated readings of public blockchain data, not financial advice.

## FAQ

### What does mint authority mean?
It is the key that can create new tokens. If it still exists, whoever holds it can print more supply and sell it. Most legitimate memecoins revoke it at launch.

### What is freeze authority?
A key that can freeze any token account so the tokens can’t be moved or sold. Regulated stablecoins like USDC keep it on purpose. For a memecoin it is a serious red flag.

### Is a “lower risk” result a guarantee?
No. The report checks known on-chain red flags. It can’t see off-chain promises, team behaviour or future decisions. A token can pass every check and still go to zero.

### Why do the top holders sometimes look alarming?
The largest accounts are often liquidity pools, exchange wallets or burn addresses. We show the owner of each account so you can check it on Solscan yourself.

### I paid but the report didn’t load.
Keep this tab open: we check the chain every few seconds and confirmation usually takes under a minute. If you closed the tab, the page URL holds your order and works again later. Still stuck? Email chris@gptshopltd.com with your transaction signature.

### Can I get a refund?
Reports are generated immediately from live data, so refunds aren’t automatic. If something broke on our side, email us with your transaction signature and we’ll sort it out.

### Which wallets work?
Any wallet that supports Solana Pay, including Phantom, Solflare and Backpack (you need 1 USDC plus a little SOL for fees). No Solana wallet? Pay the exact USDC amount shown on your order on Base from Coinbase Wallet, MetaMask, Rabby or an exchange withdrawal.
