Taiwan-based CoolBitX serves 300,000+ users globally with CoolWallet — a credit-card-sized cold-storage solution balancing military-grade security with mobile convenience.
They needed support for NEAR coin storage, staking, and transactions on the hardware wallet, and the integration needed to land fast to meet user demand.
Integrating a hardware wallet with a new blockchain protocol demands deep understanding of network-specific smart-contract architecture — expertise CoolBitX lacked internally.
The integration needed to handle complex transaction signing, staking mechanisms, and real-time monitoring while seamlessly fitting into their existing ecosystem. Speed mattered.
Security and precision are non-negotiable for us. They demonstrated solid technical judgment and iterated quickly.
We developed an end-to-end custom SDK after rigorous analysis of the NEAR network's operating capabilities and smart-contract architecture.
Integration tutorials and testing documentation were shipped alongside the code so the CoolBitX team could evolve the product independently.
Optimized JavaScript and TypeScript libraries with a custom NEAR-network API surfacing transactions, staking, and real-time status.
End-to-end support for transaction e-signing and coin staking, verified through functional and integration tests.
Detailed testing documentation and integration tutorials for internal teams to extend into future protocols.
