Wirex, a crypto payment service provider, has unveiled a non-custodial crypto debit card service named W-Pay, based on zero-knowledge proof (ZK-proof) technology. This announcement was made on October 3, marking a significant move in the crypto payment space.
W-Pay, Wirex's novel decentralized solution, harnesses zero-knowledge technology and is constructed on Polygon's Chain Development Kit (CDK). This framework offers improved scalability and enhanced security. Polygon's CDK is designed with ZK-proof technology in mind, empowering businesses and users to develop their own ZK-powered layer 2 solutions.
Scalability solutions that leverage ZK proofs have gained popularity within the crypto sphere. The ZK protocol allows one party to verify a statement's truth to another party without revealing any specific details about the statement itself. Notably, Ethereum and Polygon have been at the forefront of adopting ZK proofs.
W-Pay boasts a set of innovative features that enable non-custodial wallets and decentralized applications (DApps) to issue crypto debit cards. The decentralized approach ensures that users maintain complete control over their funds, mitigating third-party risks. Key features of W-Pay include swift and secure transactions facilitated by ZK technology, compatibility with the Ethereum Virtual Machine (EVM), and account abstraction, streamlining the transaction process by removing inherent complexities.
This ZK-proof-based decentralized solution allows for card transactions up to predetermined limits and facilitates the integration of DApps and non-custodial wallets with traditional payment systems. Wirex anticipates that W-Pay will usher in a new era of on-chain card payment services.
Wirex has a significant history in the crypto payment space, having introduced the first crypto-enabled payment card in 2015. This innovation enabled users to seamlessly use digital and fiat currencies in everyday transactions. Wirex claims a substantial customer base of over 6 million users and holds a major membership status with Visa and Mastercard.
The launch of W-Pay and its ZK-proof-based decentralized approach comes amid challenges faced by Wirex's card partner, UAB PayrNet, whose license was revoked by Lithuania's central bank in June. This development forced UAB PayrNet to cease its services in the European Economic Area.
