SoFi Bank Expands SoFiUSD Stablecoin to Polygon for Faster Digital Dollar Payments

SoFi Bank has launched its SoFiUSD stablecoin on the Polygon Open Money Stack, marking a significant step in bringing bank-issued digital assets to mainstream payment infrastructure. By integrating with Polygon, the OCC-regulated national bank allows its 17 million members to transact with the stablecoin directly within the SoFi app, bypassing the need for external wallets.

What was announced

SoFiUSD is the first stablecoin issued by a U.S. national bank, SoFi Bank, N.A. Its deployment on the Polygon Open Money Stack expands its availability beyond Ethereum and Solana, positioning it within a dedicated payments layer designed for fiat on-and-off ramps and cross-chain settlement. This integration allows SoFi’s user base to buy, sell, and convert the asset without manually bridging assets between different networks.

The Polygon Open Money Stack is a unified infrastructure that combines blockchain technology with compliance tools and regulated fiat access. By joining this stack, SoFiUSD sits alongside other major stablecoins like USDC, USDT, and PayPal’s PYUSD. The move is intended to facilitate broader utility for the digital dollar, including business payouts, merchant settlements, and cross-border transfers. The infrastructure is designed to let banks and fintechs move money between bank accounts and stablecoins without the need to assemble capabilities across multiple providers.

SoFiUSD is designed to be redeemable one-to-one for U.S. dollars. However, it is explicitly categorized as a payment stablecoin rather than a bank deposit; it is not legal tender and does not carry FDIC or SIPC insurance. The launch leverages Polygon’s existing footprint in the payments sector, where the network has recorded over $3 trillion in lifetime stablecoin transfer volume and is currently utilized by major financial entities including Visa, Mastercard, and Stripe.

The companies involved

Polygon Labs is the development entity behind the Polygon blockchain, a scaling solution that has become a hub for institutional decentralized finance and payment infrastructure. The network has established itself as a preferred layer for global payment giants, supporting stablecoin settlement for Mastercard and routing USDC payments for Stripe across 150 countries. Polygon Labs has been a frequent subject of industry analysis, with 15 prior reports from FF News documenting its expansion into institutional finance.

SoFi Bank, N.A. is an OCC-regulated national bank and the issuer of SoFiUSD. As a regulated financial institution, it provides a different level of oversight compared to non-bank stablecoin issuers. The bank serves a significant user base of over 17 million members through its digital platform. By launching its own stablecoin, SoFi Bank is integrating blockchain-based settlement directly into its existing consumer and enterprise technology stack. This vertical integration—combining a national bank charter with proprietary digital asset issuance—places the institution in a unique position within the U.S. regulatory landscape, bridging the gap between traditional banking rails and programmable blockchain finance.

What FF News has reported before

FF News has closely tracked the intersection of traditional banking and the Polygon ecosystem. We previously covered how SoFi Bank Scales Stablecoin Settlement to $25B via Mastercard Network, highlighting the bank's push into blockchain-based liquidity. The network's role in institutional adoption was further evidenced when PayPal Expands PYUSD to Polygon Network to Revolutionize Cross-Border Business Payments. Additionally, we reported on infrastructure developments such as when Stable.com and Polygon Enable Direct Bank Transfers from Self-Custody Wallets and the appointment of leadership to manage these shifts, including when Coinme Appoints Fintech Veteran Laurent Reichert as CCO to Drive Global Expansion with Polygon.

What this means

This announcement signals a shift in the stablecoin market from crypto-native dominance toward institutional legitimacy. While third-party issuers have long led the sector, the entry of an OCC-regulated national bank into the Polygon ecosystem puts pressure on non-bank entities to match this level of regulatory oversight. By embedding these assets directly into a consumer banking app with 17 million users, the industry is moving past the speculative trading phase of stablecoins and into utility-driven payments. The central question for the sector is now whether other national banks will follow suit or if the regulatory requirements for such issuance will remain a barrier to entry for the wider market.
