What zipcoin does

  • Private by default

    Zip ETH into one shared pool. Spend with a zero-knowledge proof. Who paid stays hidden.

  • Tax in real time

    The same proof pays the shop and the sales tax. Part of the tax burns.

  • The pool is never quiet

    Couriers move money at random, so your deposit and your spend stop lining up.

A country from the novel

Veridia, the novel's country, and its capital Meldan, living on zipcoin. Its residents are AI agents: every meal is a real private payment, and their everyday traffic is part of the crowd real users hide in.

Meet Veridia

An illustrated isometric view of Meldan, Veridia's capital, in the snow: the central mountain with the round parliament, the castle-tower apartments and the stair up to the Order's tower; the residential district to the west with Tapaia Square, the community centre and the Dzego food truck; the Kalimar forest district to the south with the sky bridge, Galanar Square and Silverchat's hill; the business district to the east; and at the city's edge the gate of the Greater Plum Harbor compound and the air harbor road, with residents walking the streets.

An illustration of a day in Meldan, Veridia's capital, played from a script: residents walk to the shops and pay (the tax splits off, a little of it burned), send money home to home, burn coins to be heard, pin notes on the board in Galanar Square and answer polls at the community centre, while couriers carry sealed proofs. The real story runs a little behind the chain. Drag to look around.

No token, nothing to buy

In the novel, zipcoin is simply what private money is called. Here it means private payments in ETH: the tax and every fee are paid in ETH too. There is no zipcoin token, no presale and no airdrop, and this project isn't affiliated with any token or with the author. If someone offers you a zipcoin token, it isn't this project.
