Crypto Wallet & Custody Development in Singapore: market overview
As Asia's fintech and digital-asset hub, Singapore firms need MAS-aware payment, custody, tokenisation and compliance engineering. Within that market, crypto wallet & custody development is one of the engagements we are asked for most often.
Demand is strongest across Fintech, Crypto (MAS-licensed), Logistics, SaaS and Wealth management, and every engagement is shaped by local regulation, payment habits and working hours rather than a one-size-fits-all template.

How key sectors in Singapore use crypto wallet & custody development
Crypto Wallet & Custody Development for Fintech
Fintech businesses in Singapore usually need secure onboarding, ledgers that reconcile to the cent, real-time payments and audit-ready reporting. For them, our crypto wallet & custody development typically starts with multi-chain support (bTC, ETH, EVM L2s, Solana, Tron and stablecoins) and adds compliance hooks as the platform grows. Progress is tracked on onboarding completion rate and time to approve an application.
Crypto Wallet & Custody Development for Crypto (MAS-licensed)
Crypto (MAS-licensed) businesses in Singapore usually need licence-ready custody, transaction monitoring, wallet security and clear user disclosures. For them, our crypto wallet & custody development typically starts with dapp connectivity (walletConnect, swaps, staking and NFT views) and adds non-custodial wallets as the platform grows. Progress is tracked on deposit-to-trade conversion and withdrawal processing time.
Crypto Wallet & Custody Development for Logistics
Logistics businesses in Singapore usually need live shipment visibility, warehouse accuracy, carrier integrations and digital proof of delivery. For them, our crypto wallet & custody development typically starts with compliance hooks (address screening and travel-rule integration) and adds mpc custody as the platform grows. Progress is tracked on on-time delivery rate and cost per drop.
Crypto Wallet & Custody Development for SaaS
SaaS businesses in Singapore usually need fast release cycles, scalable multi-tenant architecture and extra senior engineering capacity. For them, our crypto wallet & custody development typically starts with non-custodial wallets (seed-phrase and social-recovery wallets for iOS, Android and browser) and adds policy engine as the platform grows. Progress is tracked on release frequency and customer churn.
Crypto Wallet & Custody Development for Wealth management
Wealth management businesses in Singapore usually need reliable, integrated software that removes manual work and scales with growth. For them, our crypto wallet & custody development typically starts with mpc custody (threshold signatures with no single point of key compromise) and adds multi-chain support as the platform grows. Progress is tracked on manual hours saved and error rate.
Example: crypto wallet & custody development for a logistics business in Raffles Place & CBD
Consider a logistics company in Raffles Place & CBD (banks, wealth managers and payment institutions). A typical crypto wallet & custody development engagement would start with multi-chain support, then dapp connectivity, and finish the first release with compliance hooks — usually within 2–4 months.
Payments would run through SGQR, data would be handled under PDPA, and success would be measured on on-time delivery rate, cost per drop and warehouse pick accuracy.
Example: crypto wallet & custody development for a wealth management business in Marina Bay
Consider a wealth management company in Marina Bay (financial centre and regional hqs). A typical crypto wallet & custody development engagement would start with non-custodial wallets, then mpc custody, and finish the first release with policy engine — usually within 3–5 months.
Payments would run through Cards, data would be handled under PDPA, and success would be measured on manual hours saved, error rate and customer response time.

Because crypto wallet & custody development often touches money or digital assets, these authorities matter. We design controls with their expectations in mind; licensing remains with your regulated entity.

PDPA: compliance checklist for crypto wallet & custody development
Before launch in Singapore, we work through this checklist with your team and advisers:
- Map every personal-data field to a lawful purpose under PDPA.
- Decide where data is hosted and whether data about Singapore customers must stay in-region.
- Implement consent records plus data-subject access and deletion workflows.
- Encrypt data in transit and at rest; restrict and log administrative access.
- Prepare a breach-notification procedure that meets the timelines that apply in Singapore.
- Confirm with counsel whether licensing or registration with MAS (Payment Services Act) applies to your model.
- Document AML, fraud and transaction-monitoring controls for auditors.
Hosting and data residency for crypto wallet & custody development in Singapore
For clients in Singapore we usually host on AWS ap-southeast-1, Azure Southeast Asia, Google Cloud Singapore. The choice balances latency for local users, PDPA requirements on where personal data may be stored or transferred, and any sector rules your regulator sets. Backups and disaster-recovery copies follow the same residency decision.
