About the Client
Weld is a Ukrainian fintech company focused on enabling practical use of crypto assets for everyday payments
The product allows users to open a card linked directly to their crypto wallet and transact in real time through widely adopted mobile wallets.
The Challenge
Starting conditions increased
execution risk
Weld faced two parallel requirements:
enable real-time crypto spending through mainstream payment channels
ensure onboarding and transactions met regulatory and security expectations
Without experienced leadership in mobile payments and security decisions, Weld risked delays, rework, and an unreliable first release.
Limited in-house mobile product expertise in crypto payments increased reliance on external guidance
Speed and correctness were both critical to launch safely
Enabling real-time transactions through Apple Pay and Google Pay
Reducing onboarding friction
Entering a new, high-risk financial category meant mistakes in security or compliance would be costly
Trial-and-error delivery would introduce unacceptable launch risk
Integrating crypto wallets with traditional payment systems
Meeting regulatory and security standards
Objective
Alty joined Weld as an embedded mobile payments expert, closing the internal capability gap and leading critical product and security decisions. Enable secure crypto payments through mainstream mobile wallets while keeping onboarding simple and compliant.
The strategy prioritised decisions that reduced adoption and compliance risk from day one
Government app Diia integration was chosen to automate identity verification and shorten activation time, reducing onboarding friction and speeding first use.
Apple Pay and Google Pay were prioritised to leverage familiar consumer payment behavior, reducing adoption risk and avoiding the need to educate users on new flows.
Security and compliance were addressed upfront to prevent costly rework and reduce launch risk in a regulated environment.
These decisions removed key uncertainties and enabled a faster, safer launch.
Key design decisions included
A simplified home structure organised around everyday actions such as products, payments, and transaction history
Personalisation features allowing users to hide rarely used accounts and surface primary products
A redesigned pre-login zone enabling customers to explore services and order cards remotely through national digital identity (Diya) verification
Crypto adoption depends on integration with familiar payment rails, not standalone wallets
Security and compliance are prerequisites for trust in financial products
Reducing onboarding friction accelerates activation more than adding features
Embedded expertise reduces launch risk when entering new, high-stakes categories
