Demo. Contracts are deployed on Base but unaudited. Yield, ETH price and ZK verification are simulated. Do not deposit real funds.

Live on Base

Private dollars.
Auditable settlement.

CYPHER is a private dollar for on-chain settlement. You hold the viewing key, so you choose when an auditor verifies a transaction, and no operator holds a master key. Settlement cash also earns a simulated yield while it waits.

Of fund AUM on-chain

JPMorgan tested five privacy solutions for tokenized asset settlement. Every one required a trusted party holding a master decryption key.

Cypher is built for the gap between $98 trillion in fund assets and the $13 billion that has moved on-chain.

How it works

Four steps from ETH to private, yield-bearing dollars.

1

Deposit ETH

Mint CYPHER at 1:1 USD value. A small 0.1% fee applies.

2

Earn yield

ETH is staked and hedged delta-neutral. Yield auto-compounds into CYPHER.

3

Go private

Optional: move CYPHER into the ZK shielded pool for a 0.5% fee.

4

Redeem

Burn CYPHER for ETH at any time. A 0.2% redemption fee applies.

Why CYPHER

Selective disclosure, private settlement, and reusable compliance. Built for funds, transfer agents and banks, not retail speculation.

Selective disclosure

You grant an auditor a view of one transaction. No operator holds a master key.

Private settlement

Amount, transaction type and token type stay confidential. Addresses stay anonymous.

Reusable compliance

Verify identity once. Reuse the attestation across the lifecycle.

Yield while it waits

Settlement cash earns instead of sitting idle. A simulated 5–15% APY today, not real yield.

Stake CYPHER, Earn Up to 25% APY (Simulated)

Simulated rates, not real yield. Lock your CYPHER to earn protocol fee share. Flexible staking starts at 12.5% APY. Longer locks earn up to 25% APY.
