Solayer, Solana's eco-payment solution, has announced the launch of a non-custodial cryptocurrency debit card, which allows users to spend directly with cryptoassets without custodial funds. The product, implemented in partnership with Visa, supports real-time fiat settlement for SOL and SPL tokens, while maintaining users' full control over their private keys. Solayer said the move is designed to promote the large-scale application of cryptocurrencies in daily payment scenarios.
