Solana Wallet-Card Bridge
Frequently Asked Questions
Get clear answers about our development process, security, and timelines for integrating physical cards with Solana wallets.
A Solana Rust Wallet-Card Bridge is a secure backend service that connects traditional payment card networks (like Visa/Mastercard rails) to Solana wallets. It enables users to fund their on-chain wallets directly via card payments and, conversely, spend their crypto assets at any merchant that accepts cards. We build the core Rust-based infrastructure that handles transaction routing, compliance checks, and real-time settlement between fiat and SOL/SPL tokens.
