ASTER
Patent Pending · US 64/089,471 · Exbots Labs Inc.

Sovereign digital currency. Built by Aster, controlled by you.

Aster provisions your environment and hands over the keys — then steps back. No one else can issue, move, or freeze your money. Not even us.

View the architecture
Aster is deployed by direct engagement with monetary authorities. Briefings are arranged privately.
Proven

Every transaction and block is committed to an append-only, hash-chained ledger. Integrity is verifiable by anyone, at any time.

Isolated

Each nation runs in its own cryptographically walled environment. No other nation — and not Aster — can see in or reach across.

Sovereign

Aster provisions the environment, then steps back. There is no vendor master key over a nation's money. The central bank holds sole control.

Post-quantum

Built to NIST's post-quantum standards (FIPS 203/204/205), so the cryptography protecting the currency survives the quantum transition.

Where Aster sits — and where it is locked out

Four layers. Each boundary is an enforced isolation wall, not a policy promise.

THE SECURITY MODEL

Two guarantees, stacked

A government's currency must be safe by architecture and durable against the cryptography of the future.

Architectural isolation

Each nation runs in its own walled environment with its own keys. Aster can provision it and hand it over — but cannot issue, move, or freeze the money inside. No master key exists.

The proof: separate tenants, separate keys, no cross-boundary access.
Post-quantum durability

Classical cryptography is expected to fall to quantum computers as soon as 2030. Aster is built to NIST's finalized post-quantum standards — ML-KEM (FIPS 203), ML-DSA (FIPS 204), SLH-DSA (FIPS 205) — so the currency's protection survives the transition.

The proof: the same standards national security agencies are mandating by 2035.

A system, not a service

Aster is not sold by the seat, and not onboarded from a web form. It is evaluated, proven, and deployed through direct engagement with the institutions that answer to a nation.
