FAQ

Is Lethe live?

On Elysium Testnet, yes: you can shield, send and withdraw test HYPE, which has no value. Nothing is deployed on Elysium mainnet yet, and the contracts have not had an external security review. See Project status.

Is there a LETHE token?

Not yet. LETHE is planned: relayers stake it to be listed, and holders can stake behind a relayer to share its fees and its penalties. Basic use never depends on it. Any token called LETHE that you see today is not from this project. See LETHE token.

What does Lethe hide?

Who paid whom and how much, for every transfer inside the pool. The chain only sees encrypted notes and spent-note markers. Deposits into the pool and withdrawals out of it are public, like any token transfer. Privacy grows with the pool: every new deposit and transfer widens the crowd (the anonymity set) your notes blend into. See What stays private.

Do I need a new wallet?

No. Lethe works with the wallet you already use on Elysium. You set up separate Lethe keys for your shielded balance, and you must back them up.

Which tokens can I shield?

At launch: HYPE, shielded as wrapped HYPE, and one bridged stablecoin. The Network and contracts page lists every supported token. Being on Elysium does not make a token supported.

Will deposits earn yield?

No. Deposits do not earn yield, and they are never lent out or used as operating money.

Who holds my keys?

You do. Your keys are created on your device from fresh randomness and backed up with a 24-word recovery phrase. Your spending key, viewing keys and notes stay on your device. Nobody can recover them for you if you lose your backup.

Can I prove a payment to someone?

Yes. You can share a receipt for one transaction without showing the rest of your history. See Share a record.

What if the Lethe app goes away?

Your funds stay in the pool contract, not in the app. The app reads everything straight from the chain, so your recovery phrase rebuilds your history in any copy of it. If the relayer is offline, the app sends a withdrawal from your own wallet instead. See Keys and recovery.

How do I report a security issue?

See the Security page. Please don’t share a vulnerability in public until it is fixed.
