Cold storage, explained: what "offline keys" actually means
Why air-gapped wallets matter, how signing ceremonies work, and the trade-offs every custodian makes.
Read guideHong Kong · Virtual Asset Platform
VAULTX is a virtual asset platform concept offering spot trading, cold-storage custody and OTC execution for professional and institutional clients — engineered around segregation, verification and oversight.
01 · Trading & Custody
Trading and safekeeping are deliberately separated. Client assets sit in segregated wallets, withdrawn through controlled multi-party authorisation — never mixed with corporate funds.
01
Order routing engineered for professional workflows — configurable execution policies, real-time risk monitoring and price-time priority matching across major digital asset pairs.
02
Client assets are held in segregated on-chain wallets and stored in cold storage by default. Withdrawals require allow-listed addresses, multi-party authorisation and configurable time delays.
03
Negotiated, private pricing for large orders. Our OTC desk aims to reduce market impact with tailored execution, dual-quote benchmarking and flexible settlement across fiat and digital assets.
04
Aggregated liquidity streams with REST and FIX-style connectivity, sub-account management, automated reporting and granular permissioning for teams and treasury desks.
02 · Why VaultX
Every operational choice — from key management to reporting — is designed to be explainable to a compliance officer, an auditor and a regulator.
Client assets are legally and operationally separated from corporate funds, in dedicated wallet infrastructure.
Proof-of-reserves reporting on a published schedule, so balances can be verified independently rather than asserted.
Independent reviews, penetration testing and controls aligned to security-reporting frameworks — reviewed, not self-certified.
03 · Compliance & Licensing
Hong Kong's licensing regime for virtual asset trading platforms (VATPs) took effect on 1 June 2023 under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (Cap. 615). The Securities and Futures Commission (SFC) administers the regime, which covers safe custody of client assets, AML/CFT controls, market conduct and financial soundness.
Licensing noteThis template describes the regulatory landscape for reference only. It does not state — and must not be read to imply — that VAULTX holds any licence or regulatory approval. Always verify the licensing status of any platform directly with the SFC before onboarding.
The licensing regime for virtual asset service providers (VASPs) operating trading platforms commenced under the AMLO, administered by the SFC.
Pre-existing platforms operating in Hong Kong without a licence were required to wind down or regularise — unlicensed operation of a VATP is an offence.
A licensing regime for fiat-referenced stablecoin issuers commenced, tightening rules around reserve backing, redemption and disclosure.
Licensed platforms remain subject to ongoing SFC supervision, inspections and conduct requirements — including custody and disclosure obligations.
04 · Security
Security is layered, tested and externally reviewed. The goal is simple to state: no single person, machine or vendor should ever be able to move client assets alone.
01
The overwhelming majority of client assets are held offline in geographically distributed cold wallets, air-gapped from internet-connected systems.
02
Every movement of funds requires multiple independent authorisations. Keys are distributed across devices, roles and locations — never concentrated.
03
Cryptographic proof that client balances are fully backed, published on a recurring schedule and independently verifiable against on-chain data.
04
Crime and custody insurance arrangements, recurring third-party penetration tests and independent reviews of controls and key ceremonies.
A proof-of-reserves exercise compares the platform's stated client liabilities against on-chain holdings, so an independent third party can attest that client assets are actually present. VAULTX publishes its methodology alongside each report — the evidence matters more than the claim.
05 · Institutional Services

Complete the account application and describe your trading profile, entity type and intended activity.
Identity verification, source-of-funds review and a suitability assessment against your risk profile.

Virtual assets are highly volatile. Their prices can move sharply in either direction within short periods and may fall to zero. Investors may lose their entire invested capital. Trading virtual assets involves significant risk and may not be suitable for all investors.
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 provided for general information and educational purposes only.
You should carefully consider your financial situation, risk tolerance and investment objectives — and seek independent professional advice — before making any investment decision. Digital assets held on trading platforms may not be covered by investor compensation schemes. Past performance is not indicative of future results.
