Visa has also been a first mover in bringing stablecoins into regulated card infrastructure — piloting USDC settlement with select partners since 2021, extending settlement to Solana, and launching the Visa Tokenized Asset Platform (VTAP) for bank-issued digital currencies. When integrated with BRRR, a decentralized settlement and reconciliation layer, stablecoin-based fintechs can reach every Visa-accepting merchant in real time: a user's onchain wallet funds a card swipe, BRRR converts the crypto to the merchant's settlement currency, and Visa routes the authorization as it would for any debit card.
