Zcash has no smart contracts. ZHUSH coins exist as encrypted memos sent to one shielded address, replayed in block order by a ledger whose viewing key and state roots are public. This page is the whole rulebook — there is nothing else.
Deploy
ZHUSH deploy <TICKER> <supply> <price_zat> <creator_pubkey>
Claims a ticker. Must carry at least 0.001 ZEC. The first valid deploy of a ticker wins; every later one is ignored. Supply and price are fixed forever — there is no admin key, not even ours.
Buy
ZHUSH buy <TICKER> <holder_pubkey>
The ZEC you send is the payment: coins = floor(value ÷ price), whole coins only, capped at what is left of the supply. Anything above that (a remainder, more than the supply, a sold-out coin, less than one coin) is recorded as owed to your transaction — not refunded automatically.
Send
ZHUSH send <TICKER> <amount> <from_pubkey> <to_pubkey> <nonce> <signature>
Moves coins between holders. Authorisation is the ed25519 signature, not the payment; the memo only needs 0.00001 ZEC of dust to ride on a transaction. The nonce must be higher than your last accepted one and you must hold the amount.
Every memo must be UTF-8 and at most 512 bytes. Keys and signatures are base58. The exact grammar — and the code that folds memos into balances — lives in the open rules module, and anyone with the viewing key can replay it: see verify the ledger.
A shielded Zcash memo is 512 bytes of encrypted text that travels with a payment. Because every memo goes to one address, and because we publish that address's viewing key, the full history is readable by anyone who wants to check it — while remaining shielded from everyone else. The ledger is deterministic: the same memos in the same order always produce the same balances and the same sha256 state root. We publish the root at every height. If ours ever differed from yours, you would know.
Zcash is working on native shielded assets. There is no activation date, and we do not promise one. Every ZHUSH balance is designed to convert 1:1 into a real on-chain asset if and when that upgrade activates. Until then, a balance is an entry on this ledger and nothing more.
The sale ZEC is custodial.
ZEC sent with deploy and buy memos lands in the address we control. Trading a coin here is trusting us with that ZEC. Read this twice.
The ledger is the only record.
Your coins exist as balances computed from memos. There is no token contract, no exchange listing, no other copy. If the ledger is wrong, the published roots and viewing key let you prove it — but they do not fix it.
Manual refunds are not built.
Overpayments, purchases of sold-out coins and memos that arrive below the price of one coin are recorded as owed, with the transaction id. Nothing pays them back automatically and no refund path exists in this app.
Your holder key is unrecoverable.
It is generated in your browser and never leaves it. There is no account, email or reset. Lose the backup file and the balances are gone; leak it and whoever has it owns them.
Malformed memos are ignored.
A typo, a wrong ticker, a stale nonce, a bad signature, an underpaid deploy — the memo is counted as invalid and skipped. The ZEC still arrives and is recorded, but nothing else happens.
