Expanding the capabilities of a world-leading hardware wallet through seamless NEAR Protocol integration.

Overview

CoolBitX, a Taiwan-based blockchain security leader, has built a reputation on trust. Their flagship product, CoolWallet, offers a credit-card-sized cold storage solution that balances military-grade security with mobile convenience. Serving over 300,000 users globally, they are a dominant force in the crypto asset management space.However, the crypto landscape changes rapidly. To maintain their competitive edge, hardware wallets must constantly evolve to support emerging ecosystems. CoolBitX recognized a critical demand from their user base: the need to store, stake, and transact with NEAR coins. They required a sophisticated solution to bridge their hardware environment with the specific architecture of the NEAR network without compromising security.

The opportunity

Integrating a hardware wallet with a new blockchain protocol is not a simple API plug-in; it requires a deep understanding of the network's specific smart contract architecture. CoolBitX needed to extend their cross-chain interoperability but lacked the specialized internal resources to build a custom bridge to the NEAR network immediately.They sought a vendor with proven high-level blockchain expertise to design a Software Development Kit (SDK). The requirements were precise: the solution had to handle complex transaction signing, staking mechanisms, and real-time monitoring, all while integrating smoothly into their existing ecosystem. The goal was to deliver this upgrade swiftly to satisfy their growing user base.

The solution

Codieshub took ownership of the end-to-end development of the integration SDK. Our approach began with a rigorous analysis phase. Our blockchain architects mapped out the unique operating capabilities of the NEAR network, specifically documenting the architecture of its smart contracts and transaction processing algorithms to ensure no technical nuances were overlooked.With a solid strategy in place, Codieshub engineered a robust SDK designed to facilitate rapid communication between CoolWallet and the NEAR Protocol. We provided a suite of essential tools, including a custom NEAR network API, optimized JavaScript and TypeScript code libraries, and comprehensive integration tutorials for the CoolBitX internal team.To guarantee flawless performance, we conducted extensive functional and integration testing. This ensured that complex features, such as automated transaction recording in the ledger and real-time monitoring, functioned without latency. We delivered the final SDK alongside detailed testing documentation, giving the client full insight into the transaction e-signing and coin staking processes.

“Security and precision are non-negotiable for us. They demonstrated solid technical judgment, were open to feedback from our engineers, and iterated quickly. The collaboration felt like working with a seasoned, security-aware product team.”

The impact

The partnership delivered immediate value. Codieshub successfully completed the SDK development and integration within a tight 8-week timeline. This efficiency allowed CoolBitX to roll out support for the NEAR coin faster than anticipated, directly responding to user demand.The result is a friction-free experience where users can now seamlessly transact and store value in NEAR coins via their trusted cold-storage device. The detailed documentation provided by our team also laid the groundwork for future updates, ensuring risk-free evolution of the product.By partnering with Codieshub, CoolBitX not only expanded their asset support but reinforced their promise of delivering a cutting-edge, secure, and user-centric crypto management experience.
