Asset tokenisation · infrastructure for financial institutions

Tokenised obligations, indexed to the price of an asset

The issuer posts its coverage ceiling on-chain, the network makes issuance beyond that ceiling impossible, and the customer's key never leaves their device. You are the issuer and the licence holder. We are the machinery.

198.4% coverage of obligations, on-chain
Non-custodial the key stays with the customer

Non-custodial by design.
Who this is for

You are the issuer. We are the infrastructure.

Built for an institution that issues and services a tokenised, asset-indexed obligation under its own licence. Gold is the first case carried through to the end — its contracts are deployed, verified and running. A different underlying asset gets its own set of contracts: the price source and the unit of measure are fixed at deployment on purpose and never change afterwards — the same property that stops anyone rewriting the rules retroactively.

Bank

Deposits attracted against an asset-indexed return; a new retail product for a customer base you already have.

Payment institution

A settlement instrument and wallet on top of the fiat rails you already operate.

Crypto licence holder (NAPP)

Contracts and an application ready to run under the regulatory base you already hold.

Division of labour

What we build — what you bring

  • Smart contractsIssuance, burning, coverage ceiling, enforcement built into the contract
  • Non-custodial walletThe key sits on the customer's device — you do not hold other people's funds
  • Telegram Mini App + exchange + stakingA finished customer path: obligation↔som swap, savings
  • Coverage enforcementThe network rejects issuance above the ceiling you set

Economics

Where the partner earns

Deposits against a rate

Funds arrive for an asset-indexed return rather than an ordinary som deposit — a new reason to keep money with you.

Revenue on turnover (model, v-next)

A swap fee on the obligation↔som exchange. The current contracts charge no fee — this is a monetisation model for the next version, not revenue we claim today.

Concrete rates, the spread against the local alternative and the fee points come in a separate write-up once there is a number that can be checked. We are not inventing them here. What exists today is kept separate from what is planned.
The risk we name first

The obligation is indexed to gold — the assets behind it are in som

The obligation is denominated against the price of gold while the covering capital is held in som. A rise in gold increases the obligation in som terms. This is structural market risk, and we say so plainly instead of hiding it.

We show the size of the exposure in real time. Managing that risk sits with the partner: the treasury, the licence and the hedging instruments are already yours. We provide the machinery and the transparency, not advice about your business.
Check it yourself

Coverage can be read at any second — without trusting us or the bank

The coverage ceiling is published by a separate contract. Issuance above it is rejected by the network — not by the interface, and not by us. An attestation is valid for one hour: stop refreshing it and issuance halts on its own. Not a quarterly report, but two numbers on a chain.

The contracts are deployed and live on-chain. The source is in the repository (below).
Open source Read the sources and the discipline directly

Contract sources, tests and build settings are in a public repository, and the contracts are verified (the source matches the deployed bytecode byte for byte). Your engineer, or an automated assessor, reads them without us in the room. That is what replaces «take our word for it».

How it works and which invariants the code holds →
The working demo is the clickable Mini App above; open the real one in Telegram →. Every significant blocker found so far — fund drainage, authentication bypass, a race on the reserve, double issuance — was caught by adversarial review. That process is part of the product.
Where we are — honestly

A precise self-assessment instead of promises

Testnet. zkSync Era Sepolia. Tokens carry no monetary value — this is proof that it works, not a production issuance.
No external audit yet. The internal adversarial review process is running; an independent audit comes before any production launch.
Built and running: contracts, non-custodial wallet, Mini App, exchange, staking, the coverage mechanism, settlement.
Planned: a multisig treasury, the monetisation model, a yield on coverage under the partner's model, production issuance under a licence. The coverage and its form — gold, liquidity — are set and administered by the issuer; we are the on-chain mechanism that holds the ceiling, not a vault.
Next — a conversation

Whether this is worth a meeting is for you to decide, on the facts above

A direct line to a person, not a form. We will show the demo, hand over the addresses, and go through your economics and integration.
