Visa and Baanx Launch USDC Payment Card with Real-Time Crypto-to-Fiat Conversion

Cryptocurrency payments firm Baanx has partnered with Visa to launch a new stablecoin debit card that enables users to spend USDC directly from self-custodial crypto wallets. The initiative, starting in the U.S., leverages Circle’s USDC stablecoin and allows users to make purchases wherever Visa is accepted.

Unlike traditional crypto payment solutions, Baanx’s Visa cards use smart contracts to instantly authorize transactions. Upon payment approval, USDC is transferred from the user’s wallet to Baanx in real time, where it is immediately converted into fiat for merchant settlement. This provides seamless on-chain money management with the convenience of traditional card networks.

The partnership highlights growing momentum in the stablecoin payments sector, especially as on-chain solutions seek broader adoption through integrations with legacy financial players. Baanx is also collaborating with Mastercard on a separate crypto card linked to MetaMask wallets, indicating a wider trend of DeFi integration into mainstream payment systems.

Baanx’s stablecoin-linked cards aim to simplify global commerce, offering low-cost cross-border transactions and broader financial access through USD-backed digital assets. “In many regions, access to a stable currency is a luxury. We’re enabling people to spend USDC in a secure, self-custodial way, globally,” said Simon Jones, Baanx’s chief commercial officer.

Visa’s head of growth products, Rubail Birwadker, noted that stablecoin adoption is still in its early stages, but practical use cases like this signal growing real-world utility. The partnership follows Circle’s recent push to expand stablecoin usage through its own cross-border payment network.

As stablecoin technology matures, integrations like Baanx and Visa’s card may reshape how crypto is used in everyday finance.
