SoFi begins stablecoin settlement on Mastercard for card programs
DeFi & Yields ·
SoFi has started settling its debit and credit card transactions on Mastercard's network using stablecoins, with the program expected to exceed $25 billion in annualized volume.
The rollout marks a concrete deployment of Mastercard's push to move settlement off fiat batch cycles and onto blockchain rails, according to The Block. By tying SoFi's card program directly into Mastercard's stablecoin settlement infrastructure, the two companies are targeting more than $25 billion in annualized transaction volume moved through the arrangement.
The mechanics matter because traditional card settlement runs on batch processing during business hours, leaving weekends and holidays uncleared and creating float and timing gaps in cross-border flows. Mastercard has built toward always-on settlement that operates across intraday windows, weekends, and holidays using regulated stablecoins across multiple blockchains at once, spanning networks including Ethereum, Solana, Base, Polygon, Arbitrum, and XRPL, and supporting at least six stablecoins such as USDC, PYUSD, and RLUSD, per the Mastercard explainer. SoFi's integration applies that structure to a specific issuer's card volume rather than a pilot or test environment.
This deployment sits within a broader pattern of Mastercard partners embedding stablecoin rails into consumer-facing products. The same coverage universe notes Mastercard's Crypto Partner Program has drawn additions such as Monad and the Cardano Foundation, both exploring settlement and cross-border use cases, while separate integrations have let AI agents initiate Mastercard purchases and let MetaMask Card users spend Solana-based USDC anywhere Mastercard is accepted. Mastercard's own network reach, more than 210 countries and territories and roughly 3.7 billion cards, gives these individual programs a large addressable base if they scale beyond initial rollouts.
What remains unclear is how SoFi's $25 billion target breaks down between transaction volume already flowing through stablecoin settlement versus projected growth, and over what timeframe the figure is expected to be reached. It is also not specified which stablecoins or blockchains SoFi's implementation uses, or whether the arrangement covers both debit and credit programs equally. Distinct coverage of the launch currently comes from two sources, and further detail on transaction mechanics, cost savings, or counterparty structure has not yet been disclosed.
