Blockchain & Web3 Development Company in Hong Kong

A scoped Web3 MVP at Hong Kong rates (NFT marketplace, GameFi prototype, basic DeFi protocol) runs HKD 350,000 to HKD 1.2M (roughly USD 45K to USD 155K) over ten to sixteen weeks for smart contracts, indexer, and a Next.js or React Native front end. A custom production protocol with full audits (CertiK plus OpenZeppelin or equivalent), formal verification where applicable, and multi-chain deployment typically lands at HKD 1.5M to HKD 6M (USD 195K to USD 770K). An SFC-licensable VATP stack or HKMA stablecoin issuer stack with matching engine, custody integration, surveillance, AMLO Travel Rule, segregated cold storage, proof-of-reserves, and operational resilience pack ranges from HKD 6M to HKD 30M (USD 770K to USD 3.85M) and a six-to-twelve-month build. Hong Kong rates sit between Singapore and mainland China engineering centres because of the SFC compliance premium and the trilingual product talent scarcity. We invoice in HKD or USD per client preference.

The Securities and Futures Commission introduced the Virtual Asset Trading Platform (VATP) licensing regime on 1 June 2023 under the AMLO amendment. Every platform serving Hong Kong investors must hold the VASP designation under AMLO plus SFC Type 1 (dealing in securities) and Type 7 (providing automated trading services) licences. Operational requirements include segregated client asset custody with at least 98 percent in cold storage in air-gapped hardware, a minimum paid-up share capital of HKD 5M plus liquid capital of HKD 3M, an internal control framework (SFC FMCC and Code of Conduct), a Manager-In-Charge of Overall Management Oversight and Compliance, an AMLO compliance programme, and an operational resilience plan. OSL and HashKey Exchange were licensed by the SFC. Our builds ship with the matching engine, surveillance, custody integration, segregation, audit logs, FATF Travel Rule integration, and Conduct of Business documentation the SFC inspectors will actually examine.

Yes. The Hong Kong Monetary Authority announced the Stablecoin Issuer Sandbox in March 2024, with the upcoming Stablecoins Ordinance (passed by LegCo) introducing full licensing for fiat-referenced stablecoin issuers serving Hong Kong. Our stablecoin builds cover full mint and burn workflows, reserve asset segregation (high-quality liquid assets at SFC-licensed custodian banks), monthly reserve attestation through Chainlink Proof of Reserve or a Big Four attestation pattern (KPMG, Deloitte, EY, PwC HK), redemption SLAs (target T+1 par redemption), holder identification under AMLO, sanctions screening (OFAC, EU, HK sanctions list), and HKMA-aligned operational risk controls. Smart contracts are typically deployed on Ethereum mainnet plus Arbitrum, Polygon zkEVM, and Base for distribution, with bridge attestation handled through audited LayerZero or CCIP messaging where cross-chain is in scope. We coordinate with your TCSP, banking partner, and external auditor in the sandbox cohort.

AMLO requires every Hong Kong virtual asset service provider to identify and verify the originator and beneficiary of every virtual asset transfer at or above the HKD 8,000 threshold, transmit that information to the counterparty VASP before or concurrently with the transfer, and screen against sanctions lists (UNSCR, HKMA AML/CFT guidance). The technical layer is the FATF Travel Rule. Our builds integrate Sumsub Travel Rule, Notabene, TRP Labs (TRP protocol), or Veriscope (Shyft) depending on counterparty coverage in Asia, with fallback to email-based attestation for VASPs not yet on a Travel Rule network. We also build the JFIU suspicious transaction reporting workflow into the surveillance and compliance console so STR submissions happen inside the platform rather than on a separate channel. Sanctions screening uses Chainalysis KYT, TRM Labs, or Elliptic depending on the desk's risk appetite.

Hong Kong is positioning as Asia's RWA hub. HSBC Orion has issued multiple tokenised green bonds out of Hong Kong, the HKMA's Project Ensemble explores tokenised deposits and tokenised money market funds with banks including HSBC, Standard Chartered, Hang Seng, and Bank of China (Hong Kong), and Project mBridge is the HKMA-led cross-border wholesale CBDC pilot with the PBOC, Bank of Thailand, and Central Bank of UAE. Our RWA builds cover tokenised bonds, tokenised money market funds, tokenised gold (LBMA-grade vault attestation), and tokenised private credit, typically on permissioned chains (Hyperledger Besu, R3 Corda, Onyx by JPMorgan) or permissioned-permissionless hybrids (institutional permission layer over a public chain). KYC, transfer restrictions, jurisdictional whitelisting, dividend or coupon distribution, and corporate action handling are all part of scope. The legal wrapper sits with your Hong Kong securities counsel and the offering memorandum filing with the SFC.

Hong Kong retail Web3 product requires Traditional Chinese (zh-HK) for Cantonese Hong Kong users, Simplified Chinese (zh-CN) for mainland-adjacent professional investors and the Greater Bay Area opportunity, Traditional Chinese (zh-TW) for Taiwanese users where the licence permits, and English. We build with i18next, FormatJS, or Lingo, with translation memory in Crowdin or Lokalise managed by native HK-based linguists for the Cantonese-specific idioms (Cantonese written register differs from Mandarin written register in real ways). Numerals, dates, and currency formatting follow HKMA conventions (HKD before figures, Chinese-comma grouping where appropriate). Fonts default to Noto Sans CJK HK for zh-HK distinct from Noto Sans CJK SC. We also test against the SFC's plain-language disclosure expectations in all three written variants, because the licensee is accountable for clarity in every served language.

Cloud defaults to AWS ap-east-1 (Hong Kong), Azure East Asia (Hong Kong), and GCP asia-east2 (Hong Kong) for trading, custody backend, and compliance services, with multi-region failover to AWS ap-southeast-1 (Singapore), GCP asia-southeast1 (Singapore), or Azure Southeast Asia (Singapore) for institutional clients that prefer cross-jurisdiction redundancy under the SFC operational resilience expectations. Chains default to Ethereum mainnet plus Arbitrum, Optimism, Base, and Polygon zkEVM for EVM workloads, Solana for high-throughput consumer and payments, Aptos and Sui for new Move-based work (both have material Hong Kong developer communities), and BNB Chain where mainland-adjacent retail liquidity is the priority. Custody runs on Fireblocks, Copper, Anchorage Digital, Cobo Custody, BitGo, and Hex Trust (the Hong Kong-licensed TCSP option). Bridges are limited to audited LayerZero, Wormhole post-audit, CCIP, or Across, never custom bridge code unless the protocol team owns the audit budget for it.

An SFC-licensable VATP build typically takes nine to fifteen months end-to-end. The licensing application itself with the SFC runs in parallel and takes twelve to twenty-four months from filing to in-principle approval, with the SFC reviewing financial resources, fit-and-proper test for Responsible Officers and Managers-In-Charge, technology and cybersecurity, operational controls, AML programme, and custody arrangements. Our build phase covers the matching engine, custody integration (cold-warm-hot tiering with 98 percent cold), surveillance system, AMLO Travel Rule integration, segregation accounting, audit logging, monthly proof-of-reserves, and the operational resilience plan. An HKMA-aligned stablecoin issuer build (mint-burn workflow, reserve attestation, redemption SLA, holder KYC, sanctions screening) runs six to nine months on the build side, with the HKMA sandbox or licensing process running in parallel under their published timelines. We have shipped to this cadence in coordination with the licensee's Hong Kong securities counsel.
