Addresses
Every mint the app will touch, and how to tell the real one from the three impostors.
Check these against the explorer, not against a search result. A token list search for NVDAx returns three different tokens all called "NVIDIA xStock". One has millions of dollars behind it; the others are worth nothing and exist to be bought by mistake. The mint address is the only thing that tells them apart.
Crumble
| What | Address |
|---|---|
| Program | None. Crumble did not deploy one. |
| $CRUMBLE mint | Not minted yet |
| Incinerator | 1nc1nerator11111111111111111111111111111111 |
There is no contract address to verify, because there is no contract. What you verify instead is the transaction: open any round-up on Solscan and every instruction in it is listed, and none of them pays Crumble.

Stock tokens
The eight the app will buy. All Token-2022, all eight decimals, all issued by Backed. Every one of these mints begins with Xs, which is the issuer's own address prefix and one more thing you can check at a glance.

How the app checks them
These addresses are written into the app's config and never resolved from a symbol. On every load it asks the chain what each mint actually is and compares four things:
-
Symbol and decimals
Both have to match what the config expects. A stock token with six decimals instead of eight is not the token we meant.
-
Token program
Every stock token has to be Token-2022. An impostor minted with the classic program fails here.
-
The address prefix
A stock mint has to begin with the issuer's
Xsprefix.
If any check fails the app stops and says which token disagreed, rather than trading into something it cannot identify.
