Privacy by math, not by promise.

A shielded pool where balances and transfers are hidden by zero-knowledge proofs. Any amount, no minimum, no partner in the middle — proofs are generated in your browser.

Unlock your shielded account

Your shielded account is derived from one signature — nothing is stored, here or anywhere. Sign the same message again on any device to recover it.

Your wallet asks you to sign twice — the second signature confirms the account can be recovered.

How it works

  1. Shield — deposit ETH or USDG. You receive an encrypted note only your key can open.
  2. Send — pay another shielded address. Amount, sender and recipient stay hidden.
  3. Unshield — withdraw any amount to any address. A proof shows you own enough, without saying which deposit was yours.

What stays hidden:

  • who sends and who receives inside the pool
  • each user's balance
  • which deposit a withdrawal came from

What stays visible (true of every privacy pool):

  • amounts entering (shield) and leaving (unshield)
  • the addresses that shield, and the address that sends each transaction

Tip: wait before unshielding and use a different amount than you shielded — matching amounts and timing are the usual way pools get de-anonymised.

Milestones

01Designdone

Note pool built on Poseidon commitments, a Merkle tree, nullifiers, and 2-in/2-out zero-knowledge proofs.

02Circuits & contractsdone

circom + circomlib, no home-made cryptography. 34 end-to-end tests with real proofs, including double-spend, front-running, forged notes and inflation attempts.

03Trusted setupin progress

Phase 1 from the Ethereum Foundation’s Perpetual Powers of Tau (80 contributors). Phase 2 has a development ceremony; a public ceremony anyone can join comes before caps are raised.

04In-house reviewdone

Line-by-line review of circuits, contracts and client; findings fixed and re-tested.

05Capped mainnetdone

Immutable per-deposit and total pool caps. No admin keys, no upgrades.

06Independent auditnext

Third-party audit of circuits and contracts before caps are lifted.
