docs & receipts
no spin, just the receipts: what a launch does, what it costs, what we can and cannot touch. everything below is verifiable against the transaction you sign.
SystemProgram.createAccount
allocates the mint account. rent is paid by you, to the network, computed live for exactly this metadata size.
initializeMetadataPointer
points the token's metadata at the mint itself — no external metadata program, no extra account to rug.
initializeMint
decimals set, mint authority = you (for one more instruction), freeze authority = NULL. there is never a freeze switch.
initializeTokenMetadata
name, symbol and uri written on-chain, readable by every explorer and wallet.
createAssociatedTokenAccount
your token account for the new mint. yours, derived from your address.
mintTo
the ENTIRE supply is minted straight to your wallet. we take zero percent.
setAuthority(MintTokens → null)
the printing press is burned in the same transaction. fixed supply, forever — verifiable on solscan.
memo
one line — "greenhood:launch:v1:<mint>:<symbol>:<supply>" — your permanent ledger entry. the chain is the database.
- mint more of your coin — the authority is null. there is no admin key, and no upgrade that adds one.
- freeze a holder — freeze authority was never set. the mint ships without the switch.
- move your coins or your sol — signing never leaves your wallet. we never see a private key, not once.
- edit your history — the ledger is spl memos in your own transactions. we can't reach it.
the boundary isn't a promise. it's the program — read the transaction in your wallet before you sign and check every claim.
everything talks to solana through one endpoint: /api/rpc — a read/submit whitelist proxy. the rpc key stays server-side; your browser only ever sees chain data.
the board reads dexscreener's public feed and refreshes on a timer. no accounts, no funds, no keys.
what we write to your browser: your public address, so you stay connected. that's the whole footprint.
