10 Best Crypto Payment Gateway Development Companies in Singapore (2026)

Singapore has more crypto payment gateway products than it has development companies that will build one for you. Triple A, Alchemy Pay, and MugglePay all run out of Singapore, but they're merchants of their own gateway, not a build partner for yours. 

If you're a founder trying to figure out who can actually engineer a custom or white-label crypto payment gateway under MAS's Payment Services Act, that distinction matters more than any "top 10" list admits.

We picked companies on delivery track record, technical depth specific to payment gateways (multi-currency settlement, wallet integration, PSP-grade reconciliation), security and compliance capability, and real experience shipping into APAC. We excluded resellers that white-label someone else's gateway product and call it development.

How We Selected These Crypto Payment Gateway Development Companies

Four filters, applied in order:

• In-house engineering, not resale. A company that resells NOWPayments or CoinRemitter under its own logo isn't a development partner. We only kept firms with a dedicated payment gateway service page, a named technical approach, and at least one verifiable case study or deployment count.
• Payment gateway-specific depth, not generic "we do blockchain." Multi-currency support, fiat off-ramp integration, fraud/risk scoring, and settlement reconciliation are the actual hard parts of this build. Companies that only mention gateways as a bullet point on a broader services page got cut.
• Security and compliance capability relevant to handling merchant funds: KYT/AML tooling, audit history, and an actual answer for how they support MAS registration requirements.
• Regional relevance. Singapore has almost no dev shops headquartered there building custom gateways (the local names are gateway operators, not agencies). Two firms on this list run physical Singapore offices. The rest have confirmed APAC or global delivery experience we verified against a second source.

One deliberate exclusion: directory-listed firms with no dedicated payment gateway page or portfolio item beyond a Clutch or GoodFirms blurb. If we couldn't verify a claim on the company's own site, it didn't make the cut.

The 10 Best Crypto Payment Gateway Development Companies In Singapore

1. Troniex Technologies

Troniex builds crypto payment gateways alongside exchange, wallet, and DeFi platforms, which matters if you're a Singapore founder who'll eventually need more than a gateway alone. The team has delivered over 150 projects, from seed-stage startups to enterprise builds.

Strengths:

• Custom gateway architecture with smart contract-based decentralized processing options
• POS and mobile-app-compatible payment flows
• Multi-currency and multi-token support
• Clone-script option ships a functional gateway in 3-7 business days for teams that don't need a fully custom build

2. Antier Solutions

Antier has the broadest public footprint in this list. Beyond gateways, it builds merchant portals, stablecoin rails, and treasury integrations, which makes it a fit for businesses that want payment infrastructure bundled with custody.

Strengths:

• White-label gateways supporting 100+ cryptocurrencies
• Integrated liquidity partners for fiat-to-crypto conversion
• Delivery experience spanning North America, Europe, Asia, and the Middle East

Limitation: the breadth of Antier's service catalog means payment gateway work competes for attention with exchange and custody projects. Founders should push for a dedicated payment gateway team, not a generalist blockchain squad.

3. Blockchain App Factory

One of two firms on this list with an actual Singapore office (60 Robinson Rd), which counts for something when you need a vendor who understands MAS timelines firsthand rather than researching them for your project.

Strengths:

• 800+ completed crypto projects since 2013
• Dedicated crypto payments gateway service line
• Physical regional presence for in-person scoping calls

Limitation: With 800+ projects across a wide service catalog, ask specifically for payment gateway references rather than assuming general crypto project count translates to gateway-specific depth.

4. PixelPlex

PixelPlex leans into the fraud-prevention and compliance side of gateway development, building real-time transaction monitoring, risk scoring, and escrow functionality directly into the gateway rather than bolting it on after launch.

Strengths:

• Instant fraud alerts and transaction risk scoring
• Secure escrow logic for held funds
• Broader crypto portfolio includes a non-custodial wallet that generated $3M in revenue within months of launch, evidence the team can ship products that actually get adopted

Limitation: PixelPlex's public case studies lean toward wallets and broader blockchain engineering rather than gateway-specific work, so ask for a payment-gateway-only reference before committing.

5. LeewayHertz

LeewayHertz builds payment gateways with smart-contract automation and cross-chain support as the core architecture, not an add-on, which suits merchants who want to accept more than one or two chains from day one.

Strengths:

• Works across Ethereum, Polygon, Hyperledger, Solana, and Avalanche
• Merchant onboarding and automated settlement included in the standard build
• Documented secure development practices, including smart contract audits

Limitation: US-based with no confirmed Singapore delivery history, so timezone overlap and MAS-specific compliance guidance will need to be scoped explicitly upfront.

6. S-PRO

Headquartered in Zug, Switzerland, one of the most heavily regulated fintech jurisdictions in the world, S-PRO brings compliance-first instincts that translate reasonably well to Singapore's own strict MAS regime.

Strengths:

• FINMA-adjacent regulatory fluency
• R&D presence in Poland gives cost-competitive engineering capacity
• Dedicated crypto payment gateway service line, separate from its broader crypto development offering

Limitation: no confirmed Singapore or APAC case study surfaced in research, so ask directly for regional deployment references before signing.

7. Debut Infotech

Debut Infotech's clearest credential is concrete: it designed and built the bespoke crypto payment gateway for Triple-A, the MAS-licensed Singapore payment company, with multi-currency support and real-time transaction tracking.

Strengths:

• A verifiable, named client reference in exactly this market
• Ongoing maintenance and support post-launch
• Offices across USA, UK, Canada, and India for round-the-clock delivery capacity

Limitation: no standalone Singapore office, so all engagement runs through its US/UK/India teams rather than local staff.

8. Suffescom Solutions

Suffescom has over a decade in blockchain development and runs a dedicated USDC payment gateway product line, useful if your merchant base leans toward stablecoin settlement rather than volatile crypto.

Strengths:

• Broad payments portfolio spanning gateways, wallets, and exchanges
• Specific stablecoin-focused build track
• Offices in the US, including Los Angeles, New York, and Austin

Limitation: primary engineering base is in Mohali, Punjab, so verify which team (US or India) actually owns delivery on your project before signing.

9. Instinctools

Instinctools takes an API-first approach: clean, documented API layers that let merchants and PSPs plug crypto acceptance into existing acquiring and reconciliation infrastructure rather than replacing it wholesale.

Strengths:

• 150+ delivered fintech projects
• Integration depth across existing payment service provider ecosystems
• Notable history launching one of the first legal crypto exchanges in Eastern Europe in direct cooperation with a financial regulator, real evidence of comfort working inside a licensing regime

Limitation: Eastern Europe-based team means less built-in familiarity with MAS specifically, though the regulatory cooperation track record is a reasonable proxy for compliance discipline.

10. Oodles Blockchain

The second Singapore-office firm on this list (10 Anson Road), Oodles has been building blockchain solutions since 2009 and has completed 260+ projects across retail, healthcare, and financial services clients.

Strengths:

• Over 15 years of company history
• Singapore office for regional support
• Broad blockchain portfolio includes stablecoin and crypto wallet development alongside gateways

Limitation: gateway work is one line among many services (asset tokenization, P2P exchanges, stablecoins), so confirm the assigned team has payment-gateway-specific engineers, not generalists rotated in from other projects.

What To Check Before Hiring A Crypto Payment Gateway Developer In Singapore

Singapore regulates crypto payment activity under MAS through the Payment Services Act (PSA), which licenses Digital Payment Token (DPT) services. A crypto payment gateway development vendor doesn't need the license themselves, but the gateway they build has to support your path to one (or your operation under an exempted/sandboxed status).

• MAS/PSA awareness. Ask how the vendor's architecture supports DPT licensing requirements: transaction record-keeping, travel rule compliance for transfers, and reporting hooks. A vendor who can't answer this specifically hasn't built for a regulated Singapore client before.
• Source code ownership. Confirm in the contract that you own the code outright, not a license to use the vendor's proprietary framework. This matters most with clone-script or heavily templated builds.
• Post-launch support SLA. Get response times in writing for critical bugs (fund-affecting) versus minor ones. A gateway handling live payments without a clear SLA is a liability, not a convenience.
• Security practices specific to payment gateways. Ask about KYT (know-your-transaction) integration, multi-signature or MPC wallet architecture for held funds, and who independently audited any smart contracts used.
• Regional licensing nuance. Some vendors will quote generic "crypto compliance" without distinguishing MAS's PSA from other jurisdictions' frameworks. Push for Singapore-specific answers, not a copy-pasted compliance slide.

Cost To Build A Crypto Payment Gateway In Singapore

Pricing varies by build type, in SGD:

• White-label / clone-script gateway: SGD 8,000-25,000. Fastest path, Troniex's clone-script option lands at the lower end of this range with 3-7 day delivery.
• Custom-built gateway (single vendor, no exchange/custody integration): SGD 35,000-90,000, depending on chain support, fraud tooling, and compliance features required.
• Enterprise build (multi-chain, custody-integrated, full compliance stack): SGD 100,000+, typical for the scope Antier or LeewayHertz would quote on a full-featured build.

These ranges reflect vendor-quoted patterns across the list, not a single confirmed invoice. Get a scoped quote before committing. A gateway that skips fraud monitoring or KYT integration to hit a lower number will cost more later, either in compliance remediation or fraud losses.

How To Choose The Right Crypto Payment Gateway Development Partner For Your Business

Match the vendor to what you actually need, not the longest feature list.

• Need to launch fast and iterate later: go white-label or clone-script (Troniex is the fastest on this list at 3-7 days). You're trading customization for speed.
• Need deep compliance rigor from day one: prioritize vendors with regulatory-adjacent history (S-PRO's Swiss base, Instinctools' regulator-cooperation track record).
• Need local support and in-person scoping: Blockchain App Factory and Oodles are your only two options with physical Singapore offices.
• Need payments bundled with exchange or custody: Troniex and Antier both build across the full stack, reducing integration risk between separate vendors.

Pick The Vendor Who Can Answer The Compliance Question First

Every vendor on this list writes working code. Fewer will tell you, specifically, how their architecture supports MAS's Payment Services Act requirements before you're mid-build and discover a gap. Start there, then compare delivery timelines and cost.

Request a scoped quote from two or three vendors offering crypto payment gateway development services before deciding. A 30-minute technical call will surface more about payment-gateway depth than any portfolio page.
