01 · Stablecoin Infrastructure

Money that moves at the speed of software.

Stablecoins aim to combine the familiarity of fiat with the programmability of blockchains. NOVACHANGE designs payment, settlement and treasury flows around fiat-referenced stablecoins — with transparency about how they are backed, because a peg is a promise, not a guarantee.

  • Payment rails

    Merchant and payroll flows denominated in fiat-referenced stablecoins, with reconciliation built in.

  • Settlement

    Structured gross and net settlement workflows with audit trails an administrator can follow.

  • Treasury tooling

    Programmatic cash management with permissioned access and automated reporting.

Stablecoin riskStablecoins can lose their peg. Reserve quality, redemption terms and issuer regulation vary widely, and holding a stablecoin is not the same as holding fiat currency. Nothing here is an endorsement of any token.

02 · Trading & Custody

Execution and safekeeping, engineered together.

Trading sits beside custody in one accountable stack — segregated wallets, cold storage and controlled withdrawals underpin every order.

03 · Compliance & Licensing

Designed for a regulated era of digital assets.

Hong Kong's VATP licensing regime (in effect since 1 June 2023 under the AMLO) and the Stablecoins Ordinance (in force 1 August 2025) define the bar this concept is built towards: custody, AML/CFT, reserves and disclosure.

Our compliance postureBuilt to be inspected, not just to pass.

Compliance at NOVACHANGE is treated as product infrastructure: transaction monitoring, Travel Rule readiness, suitability assessments and segregation are designed into the flows — not bolted on afterwards.

04 · Security

Verifiable by design. Not confident by default.

Cold storage, distributed keys, proof of reserves and independent testing — the same architecture, whether the balance is a wallet or a treasury.

Layer 01

Cold StorageOffline, distributed

The overwhelming majority of client assets rest in air-gapped, geographically distributed cold wallets.

Layer 02

Multi-sig & MPCNo single point of trust

Keys distributed across roles, devices and jurisdictions. Movement requires multiple independent authorisations.

Layer 03

Insurance & AuditsReviewed, recurring

Crime and custody insurance arrangements, penetration testing and independent reviews on a published cadence.

Proof of reserves, published.

A proof-of-reserves report compares client liabilities against on-chain holdings, published on a schedule with methodology attached — so verification is possible, not just claimed.

05 · Developers

APIs that read like documentation, not guesswork.

Programmatic access to payments, trading and custody workflows — with sandbox environments, typed SDKs and idempotent requests. Built for engineering teams that ship to production.

  • Sandbox first

    Full-featured test environments with simulated assets — no real funds required to build.

  • Webhooks & events

    Signed event streams for payments, settlements and withdrawals — poll nothing.

  • Permissioning

    Scoped API keys and role-based controls that fit treasury governance models.

08 · Questions

Asked often. Answered plainly.

Is NOVACHANGE licensed or regulated?

NOVACHANGE is a design template, not a live platform, and makes no claim to any licence or regulatory approval. For any real platform you evaluate, verify its status directly on the SFC's public registers before onboarding.

Are stablecoins the same as money?

No. Stablecoins reference a fiat currency but are not issued or guaranteed by any central bank or government. They can lose their peg, redemption may be restricted, and reserve quality varies by issuer. Treat them as a distinct, riskier asset class.

Where would my assets be held?

In this concept: segregated wallets, with the majority in offline cold storage under multi-party authorisation. Withdrawals pass allow-list checks and time delays — no single person can move client assets alone.

What is proof of reserves?

A recurring report comparing client liabilities against on-chain holdings, published with methodology so third parties can verify it. It proves assets are present — it is not a guarantee of solvency or future conduct.

Can I lose everything?

Yes. Virtual assets — including stablecoins — are highly volatile and may fall to zero. Nothing here is investment advice, and platform-held assets may not be covered by investor compensation schemes. Seek independent advice.

Can I build against the API today?

The SDK snippets on this page are illustrative — no live API exists. The integration patterns shown (sandboxes, idempotency, signed webhooks) reflect conventions any production-grade platform should offer.

Important Risk Disclosure

Virtual assets — including stablecoins — are highly volatile and involve significant risk. Prices can move sharply in either direction and may fall to zero. Stablecoins can lose their peg to the asset they reference. Investors may lose their entire invested capital.

Nothing on this website constitutes investment advice, an offer to sell, or a solicitation of an offer to buy any virtual asset, security or financial product. Content is general information and education only.

Carefully consider your financial situation and seek independent professional advice before making any investment decision. Digital assets held on platforms may not be covered by investor compensation schemes. Past performance is not indicative of future results.
