No. This is an independent project using the Zether name. The original paper is by Benedikt Bünz, Shashank Agrawal, Mahdi Zamani and Dan Boneh. We share the encrypted-balance research direction, but use a different implementation. No affiliation or endorsement by the original authors or Anonymous Zether contributors is claimed. Read the origins and original sources.

ZETHER, an ERC-20 on Robinhood Chain (chain ID 4663) with the encrypted ledger built into the same contract. It trades in a Uniswap v4 pool against ETH with a 1% pool fee. Fixed supply, no owner, no admin, no upgrade path.

A private send hides the payer, recipient and amount inside a public ring of eight keys. Buying and hiding are public entries, including the amount and destination public key. Exits publish the amount and payout address; which ring key paid stays hidden. Relayer fees are public.

No. The encrypted ledger is part of the ERC-20 contract. You never deposit into a separate contract. Public trading uses an ordinary Uniswap v4 pool against ETH, so bots, routers and terminals work unchanged.

Incoming value lands in a pending ciphertext and folds into the spendable balance at the next 60-second epoch. That keeps your balance fixed while the proof is generated, so nobody can invalidate your transfer by paying you. One private spend per key per epoch.

The key decrypts and spends your private balance. The wallet keeps it in this browser’s local storage. Back it up: clearing site data or losing the device removes access permanently. There is no recovery and no admin.

No. Zether is live on Robinhood Chain with real ETH and has had no independent audit of the circuit or the contracts. The proving key comes from a two-contributor phase-2 setup on two separate machines, finalised with an Ethereum block-hash beacon; it is not a large public ceremony. Use amounts you can afford to lose.
