Zeracle
In development · testnet launching soon
Zeracle is a protocol for holding and moving a share of a freeze-resistant reserve basket. Balances and transfers are encrypted on Aztec, a zero-knowledge Layer 2 on Ethereum. The reserves behind every share sit on Ethereum, where anyone can inspect them.
Balances and transfers live as encrypted notes on Aztec. Private transfer amounts never appear in public transaction data. You decide who reads your records: a zero-knowledge proof of a single transaction shows only the details you choose.
The assets backing every share sit in a contract on Ethereum that anyone can inspect in real time. Backing is read directly from chain state, not attested by a third party.
ZRCL is a share of a reserve basket, minted and redeemed at net asset value. The basket holds decentralised dollar and Swiss franc tokens, chosen so that no issuer can freeze them at the pool. Its value moves with its assets; it does not hold a peg.
Zeracle is about confidentiality, not anonymity: control over who reads your records, the way a brokerage account is private without being hidden from lawful oversight.
Your balance is a set of encrypted notes on Aztec, and a private transfer does not reveal the sender, the recipient or the amount. The only traces are one-time markers: against a recipient's address the first time you pay them, and likely against yours on your first transfer. ZRCL is a share of the reserve basket, priced at net asset value, not a dollar: the basket targets the decentralised currency tokens DAI, crvUSD, LUSD, GHO and the Swiss franc token ZCHF.
Bridge in by depositing a supported asset from Ethereum, and out by redeeming ZRCL for an asset you choose (any part the swap can't route is paid in kind). Deposits and withdrawals are public on Ethereum, with their address and amount; private balances and private transfers are not.
Instant Pay works like a prepaid card: lock ZRCL into a private escrow once, then pay by scanning a merchant's invoice QR and confirming the amount, with no proof to generate at the till. The merchant's screen shows Paid about 10 to 15 seconds later.
Merchants price invoices in dollars, converted to ZRCL at net asset value, and follow claims, settlement requests and force-claims on one dashboard. If a customer never settles, the merchant can claim the reserved amount alone, 48 hours after the customer's spending period ends.
Prove one private transaction to an auditor or a tax office with a zero-knowledge proof that reveals only the details you choose and roughly when it happened, and nothing about the rest of your activity.
For a tax year, build a signed audit package of the whole year, which the recipient checks against the network without your keys, read as income and outgoings in ZRCL and US dollars. Or prove only the year's totals in zero knowledge, without revealing any individual transaction.
These run today on our development sandbox. None of them has launched on testnet or mainnet yet.
Testnet
Zeracle is in development, and its public testnet on Aztec is launching soon. You will be able to bridge test tokens in, hold a confidential balance, send private transfers and withdraw, before anything is live. Test tokens have no real value.
We will announce the launch here, on X and on Medium. Join the waitlist and we'll send you a ready-funded test account when testnet opens, with test tokens and Sepolia ETH.
Read from the testnet contracts; the counts are refreshed every few minutes.
Your browser reads the pool size from the public node .
Testnet
Testnet runs Zeracle on Sepolia, Ethereum's test network, and on the public Aztec testnet. Every token there is a test token with no real value, so you can try each step without spending real money.
A private send pays a 0.3% transfer fee. Instant Pay charges its fee on each payment, split between payer and merchant (half each on testnet); locking ZRCL into Instant Pay is free. Deposits and exits pay a pool fee, which the app shows before you confirm.
Leave your email address and we'll send you a ready-funded test account when testnet opens: test tokens and Sepolia ETH, with no real value. To have your address removed at any time, email privacy@zeracle.com.
