CompoSecure and MetaMask launched a new metal payment card enabling users to spend stablecoins directly from self-custodied wallets, combining traditional payment convenience with Web3 asset control. The new offering, powered by CompoSecure’s Arculus tap-to-authenticate technology, serves three primary functions: a traditional payments card; a secure authentication device; and a crypto wallet interface. The card targets crypto-native users, offering full control over private keys and on-chain transactions without relying on centralized custodians — mirroring the freedom of holding cash. The card’s real-time blockchain integration allows for features like NFT-based loyalty rewards, staking and yield, pushing crypto toward mainstream adoption. Adam Lowe, PhD, chief product and innovation officer at CompoSecure says “The issuer or platform can instantly mint an NFT, you can gamify the purchase — and it can all be automated and real time,” he said. “For the consumer, there’s also the opportunity for staking and yield. If you have a dollar in your wallet, in your pocket, it’s not doing anything for you,” Lowe said. “If you have a dollar in a yield-bearing stablecoin, every moment it’s earning you 4%-plus yield.” At the same time, CompoSecure is actively testing direct on-chain payments, which would bypass traditional rails altogether. The goal is to enable the same simplicity and ubiquity of tap-to-pay while maintaining the flexibility and efficiency of blockchain settlements. There’s no reason you can’t directly work paying on-chain,” Lowe said. “The stablecoin goes directly to a merchant wallet. We skip everything in the middle.” In cases where a merchant prefers fiat, Lowe said the solution can handle real-time asset conversion.
