The Truth Layer for Real-World Assets

Patent-pending provenance, digital twins, tokenised ownership. Every real-world asset becomes tradable and verifiable on-chain.

A / The Onyx Ecosystem

True agnostic blockchain infrastructure for any business built on trust

We integrate blockchain technology across every aspect of a business's supply chain and operational footprint. From physical product to verified consumer, every touchpoint recorded on-chain.

// Method, in five acts

From the physical world
to an entry in the digital ledger

Each asset passes through five deterministic stages. The outcome is a record that cannot be forged, altered, or quietly forgotten.

I.

The physical thing.

An asset enters the pipeline: a rough diamond, a container of critical minerals, a mining licence granted by a sovereign. Before it is named, it simply is.

INPUT ASSET
STAGE IRECEIVED
II.

The Trace Code is applied.

A patent-pending dual-code mark is affixed: a public code on the outside, legible to any counterparty, and a private code hidden within that only the holder can authenticate. Both are bound, on the chain, to the thing itself.

PROPRIETARY DUAL CODE TAMPER-EVIDENT
STAGE IIMARKED
III.

A Digital Twin is minted.

The asset acquires a permanent on-chain identity, a twin, carrying its origin, certifications, ESG, every inspection, every change of custody. A record that grows only longer.

ON-CHAIN QUERYABLE IMMUTABLE
STAGE IIITWINNED
IV.

The Tokenisation Engine draws against it.

From the twin, tokens are issued: fractional shares, debt instruments, yield products, revenue rights. Onyx builds the full stack, from the backend traceability engine to the primary marketplace and secondary market trading infrastructure. Compliance is enforced at contract level, across jurisdictions.

MULTI-CHAIN REGULATED KYC/AML
STAGE IVISSUED
V.

The asset enters the market.

Any counterparty, auditor or end consumer may scan, query, and read the full history in a single pass. The register is open, even when the trade is not.

MARKET-READY VERIFIABLE SECONDARY MARKETS
STAGE VTRADED
B / Traceability Engine

Two codes, one truth

Every asset that enters Onyx starts with Trace Code, our patent-pending dual blockchain-backed authentication system. A public code on the outside for anyone to verify. A private code on the inside for the owner to prove authenticity.

Both codes are linked on-chain. Geolocation, timestamps, and handler metadata are appended at every stage of the supply chain. Every touchpoint recorded. Every transfer immutable.

C / The Twin

Every asset gets a permanent digital identity

Not a database record. A living, queryable, on-chain representation that carries the asset's full history: where it was mined, who owned it, every inspection, every trade, every transfer of custody.

Origin data for sovereign commodity programmes. Ownership chains with timestamps and geolocation. Condition reports and certifications anchored permanently. The digital twin is the single source of truth for the physical asset it represents.

D / Tokenisation Engine

Once verified, every asset can move

Onyx builds the full stack: the backend traceability engine that verifies provenance, the primary marketplace where tokens are issued, and the secondary market trading infrastructure where they find liquidity. One platform, from twin to trade.

From asset to offering.

We build the primary marketplace where verified digital twins become tradeable tokens. Compliance rules enforced at the smart contract level across multiple jurisdictions.

  • Asset-backed tokenisation with full provenance chain inherited from The Twin
  • Smart contract compliance: KYC, AML, and jurisdictional rules enforced automatically
  • Multi-chain architecture. Deploy on the chain that fits the regulatory environment.

Ongoing liquidity for real assets.

We build the secondary market trading engine where tokenised assets find liquidity. Investors get access to real assets. Asset owners get price discovery. Settlement is automatic, on-chain.

  • Bid, offer, and settle with real-time market data and automated clearing
  • Fractional ownership opens traditionally illiquid assets to a global investor base
  • Smart contract settlement: ownership transfers execute on-chain the moment conditions are met
  • Full audit trail. Every trade, every price, every counterparty recorded permanently.

Beyond simple tokenisation.

Onyx supports structured finance products built on top of tokenised real-world assets. Each instrument inherits the full provenance chain from its underlying digital twin.

  • Asset-backed tokens: direct fractional ownership of verified physical assets with full custody chain
  • Yield instruments: fixed-return tokens backed by mining revenue, commodity flows, or operational cash flows
  • Real-world asset tokenisation: real estate, bonds, equity, and alternative assets with verified provenance on-chain
  • Multi-jurisdictional compliance with institutional-grade risk documentation.

E / Custodial Wallet Architecture

Three modes, one key hierarchy

Onyx uses a layered custody model where every user wallet is protected by nested AES encryption, passkey authentication, and platform HSM keys. Users choose their custody mode. The architecture adapts without compromising the security chain.

MODE A
Custodial
User wallet AES keys are protected by the platform public key. The platform handles wallet operations on behalf of the user. Ideal for institutional investors who want managed custody with audit trails.
User AES Key ENCRYPTED
Platform Public Key HSM
User Passphrase INNER
MODE B
Recovery
User wallet AES keys are protected by login passkey symmetrical keys. Used exclusively for wallet recovery. Multiple passkey providers (Apple, Google, hardware) ensure no single point of failure.
User AES Key ENCRYPTED
Login Passkey Sym Key RECOVERY
User Passphrase INNER
MODE C
Self-Custody
User wallet AES keys are protected by wallet passkey symmetrical keys. The user controls wallet operations directly. Full sovereignty with hardware wallet support for maximum security.
User AES Key ENCRYPTED
Wallet Passkey Sym Key USER-HELD
User Passphrase INNER

Passkey-authenticated, self-custodial crypto wallets. Users sign in with biometrics or hardware keys, then authenticate every trade, transfer, and withdrawal with the same passkey infrastructure. Full asset sovereignty without seed phrases, without centralised key storage, without compromise.
