Germany
55 employees
A financial technology (fintech) company that offers digital asset management and cryptocurrency services in the global markets. The end goal was to add a secure and user-friendly crypto wallet app for both businesses and individuals. The ewallet app needed to support multiple currencies, swaps & dApps, fiat conversion, and comprehensive DeFi wallet functionality. With their global presence, the client prioritized regulatory compliance, scalability, transparent fees, and robust KMS/HSM security to ensure user confidence in fast-evolving markets.
request background
Tailored Cryptocurrency Development Solutions for Sustainable Competitiveness
Our client is an international company providing advanced financial services for seamless cryptocurrency management. With operational load growing daily, the business needed to expand services by introducing a comprehensive crypto wallet app for both B2B and corporate users with flexible custody options.
They sought a reliable development partner to create a secure, intuitive wallet supporting multiple chains supported and currencies. During initial discovery, we identified that the optimal solution would include improving token swaps & dApps integration and fiat conversion capabilities with a transparent fees structure.
Acropolium developers also prioritized decentralized finance integration, as the client emphasized future-proof scalability and competitive advantage. The new ewallet app had to implement seedless/social recovery mechanisms, adhere to strict regulatory standards, and incorporate advanced KMS/HSM security protocols for institutional-grade asset protection.
challenge
Responding to Third-Party Inefficiencies with Custom Crypto Development Services
The main problem was dependence on third-party crypto wallet providers. When the client didn’t have enough internal resources to craft a custom crypto wallet app, they turned to off-the-shelf services that could only be customized so far, and which led to some brand misalignment as well as subpar UX.
This was becoming a security risk as available solutions were missing advanced KMS/HSM-based security features, multi-signature support, and enterprise-grade encryption practices to offer protection against today's cyber attacks. A lack of enterprise custody solutions hindered widespread corporate adoption and expansion.
Integration issues further complicated operations, as wallets couldn't seamlessly connect with the client's payment infrastructure or support crypto-fiat conversions with transparent fees. This fragmentation degraded user experience and limited revenue opportunities from swaps & dApps functionality.
As the demand for decentralized finance bloomed and the DeFi sector flourished, there were no solutions fully capable of supporting key DeFi wallet functions such as token swapping, staking, and liquidity providing. The platform also had single-chain support, which limited users to operations on a single blockchain and undermined its market potential.
User onboarding presented additional challenges, as traditional crypto wallet app solutions required complex seed phrase management. The client needed modern, seedless/social recovery mechanisms to simplify access while maintaining security standards.
During development, we had to deliver a scalable ewallet app accommodating growing user bases, managing increasing transaction volumes, and supporting integration with emerging blockchain protocols. The solution also needed to ensure regulatory compliance with GDPR, AML, and KYC requirements across the client's multi-regional operations, adding technical complexity to the architecture.
goals
- Implement advanced KMS/HSM security measures to safeguard user assets with multi-signature functionality, hardware security modules, encryption, and two-factor authentication for institutional-grade asset protection.
- Compatible with a variety of chains across multiple blockchain systems, which can allow the smooth use in managing various cryptocurrencies and gaining access to the brand-new DeFi ecosystem.
- Build the best crypto wallet app, and we ensure you’ll have a convenient & secure, instant experience across all types of transactions with your cryptocurrency anytime, anywhere. A powerful DeFi wallet that keeps control of your own private keys and your privacy, built in dApps browser functionality, and Web3 to access every dApp on the internet.
- Develop flexible custody options for institutional clients while implementing seedless/social recovery mechanisms that balance security with user-friendly onboarding and account recovery processes.
- Integrate the e-wallet app with existing payment systems, supporting fiat-to-crypto conversions with a transparent fees structure, real-time transaction tracking, and automated compliance reporting.
- Build flexible custody solutions for institutions as well as seedless/social recovery options that are both secure and user-friendly when it comes to onboarding, backup/rescan accounts. Connect the e-wallet app to the already established payment system, enabling fiat-to-crypto operations, a transparent commission structure, providing automatic compliance reporting, and tracking all history in real time.
