How it works

Sales tax

How every payment settles its sales tax in the same proof, and what the treasury's share is planned to do.

Paid in the same proof

When you pay a shop, one zero-knowledge proof pays the shop and the sales tax together. The tax is settled on the spot, and nobody learns who paid.

  • Part is burned.
  • Part pays the couriers who carry proofs and keep the network private.
  • The rest goes to the project treasury, a multisig.

The rates are fixed when the contracts are deployed, and can't exceed 10%. Shops stake ZC, and a shop that asks to be paid around the tax can be slashed: see random inspection.

Tax that keeps the market whole

Planned: the treasury's share of the sales tax goes into ZC's pool as liquidity above the price range the launch position covers, automatically and by fixed rules, so the market keeps depth past the point where the launch position ends. ETH the treasury earns fills the range below it. The positions and their fees belong to the project treasury. This isn't price support, and it doesn't pay holders.

  • The launch position covers roughly 2.9 to 2,875 ETH of fully diluted value.
  • The planned bands sit entirely outside that range, so they take no fees from holders.
  • A contract with fixed bands makes the deposits; couriers trigger it.
  • The fees go to the project treasury, a multisig.
  • There's no discretion and no rebalancing.

Planned, not live. It's being designed now, with no amounts or dates yet. Nothing here is investment advice.

A price line. The launch position covers one range in the middle; planned treasury ETH liquidity sits below it, and planned treasury ZC liquidity from the sales tax sits above it. launch position treasury ETH (planned)treasury ZC (planned) lower priceshigher prices
