9 Best Crypto Wallet Development Companies in Singapore (2026)

Every vendor page in Singapore claims to be the top crypto wallet developer in the region. Most are resellers running someone else's white-label kit with a local sales team bolted on. This list is built from 9 companies with verified wallet-specific work: MPC key management, multi-chain support, MAS-aware compliance, and shipped products you can check against a second source.

How We Selected These Crypto Wallet Development Companies

We looked for delivery track record, not marketing copy. The bar:

• Wallet-specific technical depth (MPC key management, multi-chain support, cold storage integration), not a generic "we do blockchain" page
• Security posture: SOC 2, ISO 27001, or equivalent, not a self-declared claim with no audit trail
• Singapore or MAS-market experience, either as a headquartered entity or confirmed regional client delivery
• A verifiable data point: deployment count, licensing status, or a named client, cross-checked against LinkedIn, a press release, or the vendor's own registry filing

We excluded pure directory listings and resellers with no in-house engineering team. A company that white-labels another vendor's MPC stack and adds a logo isn't a development partner, it's a reseller with extra steps.

Singapore-native supply on this list is solid: 5 of the 9 are headquartered there. The other 4 made the cut on confirmed Singapore or MAS-market delivery work, not proximity alone. That's stated here instead of padded silently into the list.

Compare The Top Crypto Wallet Developers In Singapore At A Glance

The 9 Best Crypto Wallet Development Companies In Singapore

1. Troniex Technologies

Troniex builds custom crypto wallet development for founders and fintechs who need MPC-grade security without a 12-month build cycle. The team has shipped 50+ wallets across 150+ projects in 4+ years, with a 99.6% client satisfaction rate on delivered work.

Strengths:

• MPC architecture with AES-256 encryption and threshold signing, not bolted-on 2FA
• Supports custodial, non-custodial, multi-sig, and hardware-integrated builds from one team
• ISO 27001/SOC 2-aligned development process with third-party security audits
• Multi-chain coverage across 100+ tokens, including BTC, ETH, SOL, BNB, Polygon, and TRON

Limitation: Troniex is not headquartered in Singapore, so MAS licensing navigation is a build-partner conversation, not an in-house regulatory desk.

2. ChainUp

ChainUp is a Singapore-headquartered blockchain infrastructure provider that's been running since 2017, serving over 1,000 clients across 30 countries. Their white-label MPC wallet is the product to look at if speed matters more than a fully custom build.

Strengths:

• Splits private keys into multiple secure shares, so no single point of failure
• Claims support for 200+ chains with rapid onboarding for new tokens
• SOC 2 and ISO certified, with compliance-ready audit logs and role-based access controls
• Deep existing relationship with Singapore's exchange compliance requirements from their exchange product line

Limitation: ChainUp's core business is exchange infrastructure. Wallet is one product line among several, so expect a platform-fit conversation rather than a from-scratch custom build.

3. Cobo

Cobo runs a Singapore regional headquarters and has operated since 2017, managing custody for 500+ institutional clients across licensed operations in Singapore, Hong Kong, the US, and Lithuania.

Strengths:

• Full spectrum of wallet tech: custodial, MPC, and smart contract wallets on one platform
• 80+ blockchains and 3,000+ tokens supported
• SOC 2 Type II and ISO 27001 certified, with actual regulatory licenses, not just claims
• 8 years of uninterrupted security track record protecting billions in institutional assets

Limitation: Cobo is a custody platform you integrate with, not a development shop that builds you a bespoke wallet from a blank page. Right fit for institutions plugging into existing infrastructure, wrong fit for a founder wanting a fully custom product.

4. Liminal Custody Solutions

Liminal is Singapore-headquartered and builds MPC and multi-sig wallet infrastructure for exchanges, Web3 platforms, and brokerages, with clients including ZebPay and DiFx.

Strengths:

• MPC and multi-sig combined with HSM vault options for institutional clients
• Supports 1,200+ tokens
• Compliance and firewall tooling built in: AML monitoring, transaction governance, and Travel Rule support
• Insured custody, not just secured custody

Limitation: Their public materials don't disclose a founding year or assets-under-custody figure, which makes it harder to benchmark their scale against Cobo or ChainUp without a direct sales conversation.

5. Infinito

Infinito is a Singapore-based blockchain house with 50+ specialists and a universal mobile wallet product used across multiple chains, plus a white-label blockchain platform for businesses building their own branded app.

Strengths:

• Mature consumer wallet product (Infinito Wallet) as proof of shipped, working software
• White-label ecosystem covering wallet, app marketplace, and payment protocol (InfinitoPAY)
• Supports major chains including Bitcoin, Ethereum, EOS, and all ERC-20/NEP-5 tokens

Limitation: Their public materials cite 3+ years of team experience, shorter than several others on this list. Ask for their current chain-support roadmap since the wallet's coverage list moves faster than the marketing page updates.

6. UKISS Technology

UKISS is Singapore-incorporated and makes Hugware, a hardware wallet that removes the recovery seed phrase entirely, patented across 20+ countries.

Strengths:

• Hardware-first approach removes phishing and seed-phrase-loss risk by design
• Singapore-incorporated with a physical local office (Ayer Rajah Crescent)
• Patent portfolio spans major markets: China, Europe, US, Japan, Southeast Asia

Limitation: This is a product company, not a custom development partner. If you need your own branded hardware wallet built from scratch, UKISS is a component supplier to evaluate, not a dev shop to hire.

7. Antier Solutions

Antier has delivered 500+ enterprise-grade crypto wallets across 30+ countries, including Singapore, with MPC key management, biometric layers, and AI integrations as recent additions to their build stack.

Strengths:

• Largest disclosed deployment count on this list: 500+ wallets
• Multi-currency wallets with biometric authentication and cold storage compatibility
• Track record spans asset managers, Asian exchanges, and fintech clients specifically

Limitation: Antier is not Singapore-headquartered. Their Singapore work is client delivery, not a local team with MAS-specific regulatory depth in-house, so budget for that gap in scoping conversations.

8. SoluLab

SoluLab positions its white-label wallet specifically for Singapore's Payment Services Act framework, bundling MAS licensing navigation into the build.

Strengths:

• Explicit PSA licensing support across Money-Changing, Standard Payment Institution, and Major Payment Institution categories
• Multi-chain support for Ethereum, Polygon, Solana, and Bitcoin
• 8-16 week white-label deployment timeline, roughly a third the time of a native build
• Multi-sig, cold storage, and hardware custody integration included

Limitation: Their public case studies don't name specific Singapore clients, so the PSA licensing claim is worth verifying directly with a compliance consultant before treating it as a substitute for legal counsel.

9. LeewayHertz

LeewayHertz builds crypto wallets with a specific strength in enterprise system integration: wallets that plug into ERP platforms, compliance monitoring, and financial reporting infrastructure, not just standalone apps.

Strengths:

• Mobile, browser-extension, and backend custody infrastructure all built in-house
• Strong enterprise integration track record: ERP, compliance tooling, financial reporting
• Was acquired by The Hackett Group in September 2024, adding enterprise consulting depth to their delivery bench

Limitation: LeewayHertz is India-headquartered with global delivery, not a Singapore-based team. Post-acquisition, confirm their current wallet-specific team hasn't been absorbed into broader consulting work before scoping a project.

What To Check Before Hiring A Crypto Wallet Developer In Singapore

Singapore doesn't have a wallet-specific license. Wallet providers typically fall under the Payment Services Act if they're handling custody or facilitating payment transactions, administered by MAS. Ask any vendor exactly which PSA license class applies to your product, because "we're MAS-compliant" without naming the license class (Money-Changing, Standard Payment Institution, or Major Payment Institution) is a vague claim, not a verified one.

• Source code ownership: Confirm in the contract that you own the code outright, not a license to use the vendor's proprietary framework indefinitely. White-label deals especially blur this.
• Cold storage and MPC implementation detail: Ask which MPC protocol they use and whether key shares are held across independent parties or all inside the vendor's own infrastructure. The second setup reintroduces a single point of failure under a different name. Read up on MPC wallet development if the term is new to your team before the vendor call.
• Audit history: Request the actual smart contract or security audit report, not a badge on the website. Ask who ran it and when.
• Post-launch SLA: Wallet infrastructure needs ongoing patching as chains upgrade. Get the support SLA in writing, including response time for a critical security incident.
• PSA licensing pathway: If your product needs an MPI or SPI license, ask whether the vendor has actually taken a client through that process with MAS before, not just that they're "aware" of the requirement.

Cost To Build A Crypto Wallet In Singapore

Costs vary by build type:

• White-label deployment: SGD 200,000-670,000, based on SoluLab's disclosed USD 150K-500K range converted at current rates. Covers licensing, infrastructure setup, and compliance integration. Timeline: 8-16 weeks. Troniex's white-label crypto wallet track runs on a similar timeline for founders who want to skip the full custom build.
• Custom build: Typically 3-6x the white-label cost given the longer engineering cycle, based on the 4-6 month timelines quoted by Troniex, Antier, and LeewayHertz for fully custom work. Get a fixed-scope quote rather than a time-and-materials estimate, since wallet security work has a habit of expanding scope mid-build.
• Hardware wallet unit cost: A different cost model entirely if you're evaluating a product like UKISS's Hugware rather than commissioning custom development. Per-unit pricing, not a project fee.

None of the vendors above publish exact Singapore-market pricing on their sites. Treat any range here as a starting anchor for RFP conversations, not a quote.

How To Choose The Right Crypto Wallet Development Partner For Your Business

Match the vendor type to what you actually need, not to who has the biggest deployment number.

• Fast market entry, standard feature set: ChainUp, SoluLab, or Troniex's white-label track for an 8-16 week launch.
• Institutional custody with existing licenses: Cobo or Liminal if you're integrating with a licensed platform rather than building your own from scratch.
• Fully custom product with deep security requirements: Troniex, Antier, or LeewayHertz for a build that starts from your spec, not a template.
• Consumer-facing branded app: Infinito for a proven mobile wallet foundation.
• Physical hardware product: UKISS as a component supplier, not a software dev partner.

Picking A Partner That Survives An MAS Audit

The vendors on this list range from licensed custody platforms to custom dev shops to a hardware manufacturer, and they're not interchangeable. The single factor that matters most: can this vendor name the specific PSA license class your product needs, and have they actually taken a client through MAS licensing before. Everything else, chain count, deployment numbers, timeline promises, is secondary to that one check.

Start by shortlisting 2-3 vendors whose specialty matches your build type from the comparison table above, then request a scoping call that specifically covers source code ownership, MPC implementation details, and post-launch SLA before signing anything.
