Wirex first launched its crypto debit card in 2015 and currently claims over six million customers. Crypto payment service provider Wirex announced the launch of a zero-knowledge proofs -based non -custodial crypto debit card service called W-Pay. Wirex’s new decentralized solution utilizes Zero-Knowledge technology and is built on Polygon's Chain Development Kit (CDK), promising increased scalability and security. Polygon CDK has been built with ZK proofs in focus as it enables companies and users to build their own ZK-powered Layer 2 rail. ZK-proofs-based scalability solution has become quite popular in the crypto space as the zero-knowledge protocol allows one party to convince another party that something is true without disclosing anything other than the fact that the claim in question is true. Over time, Ethreum and the likes of Polygon have seen the most development related to ZK-proofs. W-Pay offers a range of ground-breaking features that enable non-custodial wallets ...

Ethereum layer-2 protocols continue to attract the biggest players in the decentralized finance sector, with liquidity protocol Aave deploying on scaling network Metis. Decentralized liquidity protocol Aave has deployed on Ethereum (ETH) layer-2 scaling platform Metis, bringing a host of decentralized finance (DeFi) Features and products to its ecosystem. Aave’s community recently voted in favor of a proposal deploying on zero-knowledge (zk) proof EVM zkSync, paving the way for the DeFi protocol to tap into powerful performance improvements delivered by the scaling infrastructure. A number of different zk-proof-powered layer-2 protocols are being developed by Ethereum ecosystem participants, providing the wider space with a choice of infrastructure to scale their respective platforms. While Aave has yet to deploy on zkSync Era, it has announced its deployment of V3 of its protocol on Optimistic rollup scaling protocol Metis. The latest version of Aave’s protocol is touted to benef...
