ゼロ.IO

Built for people. Loved by agents.

Zero Reality is a Swiss practice in Zug, continuing research we started in Frankfurt in 1999. We take on a small number of hard engagements a year — CTO/CPO-in-residence work in payments, identity and games — and build our own protocols and products in between.

ビルディングナウ

One proof layer, two apps for one generation

game3.id is the layer underneath. Every app asks how old you are; with game3.id a player answers once, with a zero-knowledge proof a game can check without learning who they are, and hands scoped authority to the agents acting for them.

spray.cash gives young Europeans money that is truly theirs: a self-custodial wallet on regulated euro and franc tokens, where every spend, theirs or an agent's, stays inside limits they set. Parents see the limits, not the life.

Rizz is chat that proves your age, not your passport: a venture of LAB75, where the practice began, with us as technical implementation partner. No date of birth is stored, and parents of younger members see where they hang out, not what they say.

Alongside them, wasd.fund tests whether agents can read a thesis and vote on capital, and ktrl.one keeps the interface question honest: a game controller players and companions share.

ディシプリン

Settlement, custody, and scale

We've built the settlement layer for real transactions: on-chain price feeds via DIA, cross-chain bridging via LayerZero, stablecoin wallets with card issuance, on-chain fundraising and governance, token issuance backed by vaulted metal. That's the same infrastructure a transacting machine needs — custody, compliance, settlement — whether the counterparty is a person or a process running unattended. We build it once, for both.

クライアントワーク

Regulated rails, for clients

As CTO-in-residence at Denario, 2024 to 2026, we architected the stack behind DSC and DGC: Swiss tokens, each redeemable for an ounce of vaulted silver or gold, rated BBB+ by Particula.

For a confidential client, we built a stablecoin wallet and card stack in about four months, made to carry donations from a round-up at the till to an institutional grant on one traceable rail. Charitable giving runs to hundreds of billions a year; almost none of it moves this way yet.

2017–2025 – サンセット

GameDAO, Battlepass and ZERO Network

Before identity, a stack for games. ZERO Network, our own chain conceived in 2017, won two Kusama parachain auctions; GameDAO ran on it, giving studios and guilds on-chain fundraising and governance; Battlepass added subscription seasons, quests and rewards for esports fans, launched with WAVE Esports. All three are retired, and what they taught us runs through game3.id.

グラフ

Vision

Stop re-rolling for a result you can't get back. Vision generates assets, levels and worlds as versioned artefacts — same seed, same output, every time — so you build on what worked instead of starting over. Full fidelity, fully composable, no slop. It runs as a deterministic graph, wiring your model of choice into your existing toolchain — Blender and Unity to start. Early access is opening in small batches.
