The MUSE program's accounts and the events it writes to transaction logs are the only source for launch rules, curve state, balances, fees and claims. Token names and images come from each mint's own metadata and the file it links to.
A buy or a sell re-reads the launch account right before the wallet opens, and every transaction is simulated before you sign it, so a program error is shown before the wallet ever asks.
Receipt over animation. A wallet prompt is not a confirmed transaction; the confirmed signature, linked to Solscan, is.
Discover, the registry and every token page read the program directly when they load; a token page keeps refreshing every few seconds. The only thing in between is the site's RPC relay, which holds a list of launches for at most four seconds.
When a read fails, the page says it could not read Solana instead of showing an older number.
Price is the price of the tranche the next token comes from, in SOL per token. Market cap is that price times the mint's current supply. Raised is the reserve backing the curve. Volume and trade counts are counters in the launch account; the chart is drawn from the program's trade events. After graduation, price and market cap are read from the Meteora pool account and the chart is DexScreener's view of that pool.
Holder lists come from the RPC's largest-accounts view and show the twenty largest token accounts; the curve vault is labelled as the curve.
A MUSE profile belongs to a wallet address. Launches and blueprints are attributed only to the addresses the program records. A display name, bio, X handle or avatar is off-chain text the wallet signed; it is not identity verification or endorsement.
Claimable is the balance the launch account has credited to a wallet right now: creator fees, blueprint royalties. Pot wins are paid in the winning transaction and are not a claim.
After a pool opens, the figure also includes the creator share of pool fees the locked position has earned but nobody has collected yet; it is read by simulating a collect, and claiming collects them in the same transaction. Nothing on MUSE is an APY or a promised return.
Open a token page, read its rules and addresses, compare the wallet prompt with the quote, and follow the Solscan link after confirmation. The exact mechanics are in the docs.
