ZecBus

Non-custodial · open source · no sign-up

Leave the Zcash pool together.

When you deshield ZEC alone, the transparent side shows a lone, oddly-sized exit — easy to link back to you. A bus is a rendezvous: several people agree to leave the shielded pool with the same blend-in amount, on the same route, in the same short window. On-chain you become N look-alike swaps instead of one.

See boarding buses How it works

ZecBus never holds your funds or keys and never stores your destination. It only matches route, amount and timing — you sign and broadcast your own swap.

How it works

  1. 1

    Pick a blend-in amount

    Choose a common denomination others also use, and the asset you want to exit to (BTC, ETH, RUNE…). Odd amounts fingerprint you — ride a round one.

  2. 2

    Reserve a seat

    You join (or start) a bus for that exact amount + route. ZecBus hands you a one-time seat token. No account, no email, nothing stored about you.

  3. 3

    Wait for it to fill

    When enough riders board, the bus turns ready and a short departure window opens.

  4. 4

    Broadcast your own swap

    During the window, everyone broadcasts their own ZEC→asset swap from their own wallet, to a fresh destination. N identical swaps land together — one anonymity set.

    What this does — and doesn't — do

    For agents (MCP)

    ZecBus is also a set of Model Context Protocol tools on the winbit32 gateway, so an AI agent can ride a bus on your behalf. Point your client at:

    Tools in this family:

    Example: zec_bus_join({ to: "BTC.BTC", amount: 1, minPassengers: 5 }) reserves a seat leaving the pool to BTC at a 1 ZEC blend-in amount. The same free REST surface lives at GET /v1/zec/bus on the gateway.

    Coming to WINBIT32

    ZecBus is being built into WINBIT32's Privacy Suite and Money Manager. There, the bus is wallet-connected: when your bus is ready, one click prefills the built-in Exchange to broadcast your own ZEC exit swap — no copy-pasting amounts, no leaving the app. It joins the existing Zcash amount-privacy advisor (blend-in amounts + split planner) and the Monero / Dash privacy tools.

    Next: an anonymous zk reputation layer (the Poseidon reputation circuit in this repo) so one actor can't quietly take most seats on a bus and shrink everyone's anonymity set.
