Blockchain & Web3 Development Company in Singapore

A scoped Singapore Web3 proof of concept (smart contracts on Polygon or a testnet, a custodial or self-custodial wallet, fiat-to-crypto onramp through StraitsX or Coinhako, basic admin tooling) runs SGD 90,000 to 220,000 over eight to twelve weeks. A production tokenisation or RWA platform aligned to Project Guardian patterns, with permissioned chain settlement, ERC-3643 or ERC-1400 token standards, KYC plus accredited investor gating under the Securities and Futures Act, and tier-one smart contract audit, lands at SGD 350,000 to SGD 900,000. A full licensed exchange or DPT service stack with Fireblocks MPC custody, Travel Rule connectivity, Chainalysis KYT, MAS Notice PSN02 AML programme, PayNow integration, and an MAS Payment Services Act licensing pack ranges from SGD 800,000 to SGD 2.5M. Stablecoin issuance under the MAS framework, with reserve management, daily attestation, and the at-par redemption infrastructure, typically starts at SGD 1.2M. Singapore rates sit above Bangkok and Ho Chi Minh because of MAS-regulated talent premium and audit firm pricing, and we give fixed-fee proposals rather than open T and M estimates.

Under the Payment Services Act 2019, any business carrying on a digital payment token service in Singapore needs a Standard Payment Institution licence (under SGD 3M monthly transaction value or stored value), a Major Payment Institution licence (above those thresholds), or a Money-Changing licence, depending on activity mix. DPT services include dealing in DPTs, facilitating exchange of DPTs, inducing or attempting to induce any person to enter into a DPT agreement, accepting DPTs from one party for transfer to another, and arranging for the transmission of DPTs. Pure smart contract authoring, non-custodial wallet software, and decentralised finance interfaces that do not custody customer funds may sit outside the licensing perimeter, but the perimeter is fact-specific and the MAS view on DeFi facilitation tightened materially over 2022 to 2024. Our discovery phase runs a licensing scope against your activity, prepares the application pack (AML and CFT policies, risk assessment, technology risk management, key personnel fit and proper, prudential requirements), and coordinates with your Singapore law firm. We do not give legal advice, but we deliver the technical evidence MAS requires for a clean application.

The August 2023 MAS Stablecoin Regulatory Framework is currently the most prescriptive single-currency stablecoin (SCS) regime in any major jurisdiction. To use the MAS-regulated label, an SCS must be pegged to SGD or any G10 currency, fully backed by reserve assets equal to or above 100 percent of par at all times in high-quality liquid assets (cash, cash equivalents, and short-dated sovereign debt), redeemable at par within five business days, audited monthly, and issued by an entity holding the appropriate Major Payment Institution licence. Capital, prudential, and business conduct requirements apply. Our stablecoin engagements build the issuance and redemption rails, integrate with the partner bank for reserve custody (DBS, OCBC, UOB, Standard Chartered Singapore typically), wire the at-par redemption flow against PayNow and FAST for SGD or SWIFT for G10, instrument the daily and monthly attestation pipeline against an external auditor (Deloitte, KPMG, PwC, EY), and deliver the technology risk and operational risk evidence MAS requires. StraitsX XSGD is the operating reference point in Singapore.

Yes. Project Guardian is MAS's industry tokenisation programme, running since 2022 with DBS, JPMorgan, Standard Chartered, Marketnode, UOB, HSBC, Citi, Ant Group, BNY Mellon, OCBC, and Schroders across asset management, FX, and fixed income workstreams. The programme has validated patterns for tokenised funds, money market funds, tokenised bonds, FX settlement, and atomic delivery-versus-payment between regulated counterparties. We ship RWA platforms on the same patterns: ERC-3643 or ERC-1400 permissioned token standards, allowlist-based investor onboarding under the Securities and Futures Act accredited and institutional investor categories, Chainlink Proof of Reserve or institutional oracle feeds for NAV and pricing, on-chain DvP using HTLCs or shared settlement smart contracts, and integration with Marketnode or your transfer agent for register-of-members reconciliation. Where the deployment crosses borders, we map Travel Rule, FATF, and the PDPA transfer limitation obligation into the design. Public chain deployments are typically Polygon PoS, Avalanche subnets, or Arbitrum. Permissioned deployments are typically Hyperledger Besu or Quorum.

MAS Notice PSN02 imposes the FATF Travel Rule on DPT service providers in Singapore: for any DPT transfer above the threshold, the originator VASP must transmit originator and beneficiary identifying information to the beneficiary VASP, and the beneficiary VASP must apply equivalent obligations. We integrate Travel Rule connectivity through the major messaging standards (Notabene, Sumsub Travel Rule, TRP, TRISA, OpenVASP, Shyft) chosen based on the counterparty mix you actually trade with, since interoperability between standards is still partial. We wire the originator and beneficiary VASP due diligence flow (sanctions screening, jurisdictional permissibility, name and wallet-address matching), the self-hosted wallet handling rules MAS expects (additional due diligence above the threshold), and the audit trail PSN02 examiners ask for. Transaction screening sits on top of Chainalysis KYT, TRM Labs, or Elliptic Lens with risk-based rules that fit your customer segment. The implementation typically takes eight to fourteen weeks depending on counterparty coverage.

MAS-regulated DPT licensees and banks running custody (DBS DDEx, HashKey Singapore, Sygnum Singapore patterns) operate a tiered model: cold storage for the bulk of customer assets using HSM-protected keys with multi-person, multi-location physical controls (Anchorage, Ledger Vault, BitGo Trust, Fireblocks Cold Storage, Copper ClearLoop); warm storage with MPC or threshold signature schemes (Fireblocks MPC-CMP, Copper Walled Garden, Anchorage Cosigner) for operational liquidity; and hot wallets sized to cover settlement windows only, behind HSM or MPC with circuit breakers and velocity controls. Segregated wallets per customer, on-chain proof of reserves where supported, and an independent custody auditor are increasingly expected. We build the custody orchestration layer, the segregation accounting model, the reconciliation pipeline against the chain and against the order book, and the operational runbook MAS technology risk reviewers expect under MAS TRMG. Insurance is typically placed through Lloyd's syndicates or specialty crypto insurers (Evertas, Coincover) and we deliver the technical evidence those underwriters require.

End-to-end timeline from kickoff to live trading under an MAS Major Payment Institution DPT licence is typically eighteen to thirty months, dominated by MAS engagement rather than engineering. Weeks 1 to 8 are the licensing scope, AML and CFT policy build, technology risk documentation, and the application pack. MAS review typically runs nine to eighteen months with multiple rounds of clarification, on-site assessment, and key personnel fit and proper. In parallel, we build the platform: custody integration, trading engine, fiat rails (PayNow, FAST, SWIFT), Travel Rule connectivity, KYT and transaction monitoring, customer onboarding with Singpass and MyInfo where retail is in scope, and operational runbooks. The platform is typically MAS-ready within nine to twelve months on the engineering side. Live trading begins after MAS in-principle approval and final licence grant. We have patterned implementations against the public profiles of HashKey Singapore, Independent Reserve, Coinhako, and Sygnum Singapore. Tokenisation-only RWA platforms operating under SFA exemptions or via licensed counterparties can launch materially faster.

Funding for blockchain and Web3 work in Singapore is more selective than for general AI or fintech but still meaningful. The MAS Financial Sector Technology and Innovation (FSTI) scheme has historically co-funded proof-of-concept work on tokenisation, distributed ledger, and digital identity for regulated FIs, including Project Guardian participants. The MAS Financial Sector Development Fund (FSDF) supports broader sector capability uplift. EDB Pioneer Status and the Development and Expansion Incentive (DEI) can apply to substantive technology investment that creates regional headquarters or core IP in Singapore. Enterprise Singapore's Enterprise Development Grant supports up to 50 percent of qualifying project costs for SMEs, including blockchain capability builds. AI Singapore 100E does not typically fund pure blockchain work but can fund AI-on-chain hybrid problems. The Variable Capital Companies framework is relevant for tokenised fund structuring. We deliver the time-tracked logs, technical narratives, and audit trail these programmes require. Final eligibility sits with your grant consultant, MAS, EDB, or Enterprise Singapore.
