Cryptocurrency wallet provider Argent is teaming up with Mastercard and blockchain startup Kulipa to launch a new crypto payment card. The protocol will feature Starknet's zero-knowledge technology. Axel Cateland, co-founder and CEO of Kulipa, said: "We are proud to launch Argent as our first non-custodial wallet and to partner with Mastercard to continue contributing to the adoption of daily crypto payments worldwide." Kulipa-branded cards convert Circle's USDC or Paxos-branded stablecoins into fiat currency in the background, which means merchants don't need to integrate crypto payment tools. "This process ensures a smooth debit card payment experience for any MasterCard user and merchant worldwide, with on-chain settlement on virtually any blockchain," the release said.
