SoFi Bank is taking its bank-issued stablecoin SoFiUSD to Polygon, where more than 17 million SoFi members can buy, hold and convert the token inside the SoFi app without a separate crypto wallet. The move adds a third network after Ethereum and Solana and places a cash-backed, non-yielding dollar token alongside USDC, USDT and PYUSD in a payments stack built for institutional and consumer flows.
🔑 En bref
- SoFiUSD is now live on Polygon Open Money Stack, after Ethereum (December 18, 2025) and Solana (April 2, 2026).
- The token is issued by SoFi Bank, N.A., a national bank supervised by the OCC, and fully backed by cash.
- SoFiUSD pays no yield and is neither a deposit nor insured by the FDIC or SIPC.
- Bullish became the first centralized exchange to list SoFiUSD (NYSE: BLSH) on June 22, 2026.
A third network for a bank-issued stablecoin
On November 12, 2026, Polygon Labs announced that SoFiUSD is available on Polygon Open Money Stack (OMS), a layer that combines fiat on-ramps, embedded wallets and cross-chain settlement. There, SoFiUSD joins Circle’s USDC, Tether’s USDT and PayPal’s PYUSD, which are already supported. According to The Block, the integration provides access to wallets, fiat rails, stablecoin conversion and cross-chain settlement through a single interface, aimed at payments, settlements and cross-border transfers.
The distinguishing feature is the user path. Polygon Labs says SoFi’s members can buy, sell, hold and convert SoFiUSD on Polygon directly within the SoFi app, without manually bridging assets between chains. Traditional bridges typically lock tokens on the origin chain before minting an equivalent on the destination chain, creating execution and slippage risk. Bridges have also been repeatedly targeted by attacks that caused losses in the billions of dollars.
Issuance mechanics and legal status
SoFiUSD is issued by SoFi Bank, N.A., a national bank regulated by the Office of the Comptroller of the Currency (OCC). The token is redeemable one-for-one for US dollars, subject to applicable conditions. According to Eco’s analysis, it is fully backed by cash held at SoFi Bank, in the bank’s settlement current account at the Federal Reserve. Issuance and custody are handled by BitGo’s stablecoin platform as a service. When a partner deposits dollars, an equivalent amount of SoFiUSD is minted on the blockchain; on redemption, tokens are burned and cash is released. Independent reserve attestations are published.
| Feature | SoFiUSD |
|---|---|
| Issuer | SoFi Bank, N.A. (national bank, OCC) |
| Reserves | Cash in settlement account at the Fed |
| Issuance and custody | BitGo (platform as a service) |
| Yield | None, prohibited under the GENIUS Act |
| FDIC or SIPC coverage of the token | No |
This structure does not turn SoFiUSD into a bank deposit. The joint SoFi-Mastercard release states that the token is not a deposit, is not insured by the FDIC or SIPC, is not guaranteed by the bank, is not legal tender and can lose value. FDIC protection applies to SoFi Bank’s deposits, not to the token itself. Reserves are held in cash, unlike many non-bank stablecoins that rely on Treasury bills, repurchase agreements and other cash equivalents.
“SoFi is well positioned to bring stablecoins into traditional finance, because it combines the regulatory framework of a national bank with the scale of a major consumer and enterprise technology platform.”
Marc Boiron, CEO of Polygon Labs
Payments: 24/7 settlement and cost
The core gain is both temporal and financial. ACH and wire transfers operate during banking hours and can take several days, whereas a blockchain transfer can settle in seconds or minutes at any hour. Eco estimates that a traditional international wire typically costs $30 to $50 and takes two to five business days, while a stablecoin transfer can settle in seconds for a fraction of a cent.
| Metric | Traditional international wire | Stablecoin transfer |
|---|---|---|
| Cost | $30 to $50 typical | Fraction of a cent |
| Settlement time | 2 to 5 business days | Seconds to minutes |
| Availability | Banking hours | 24/7 |
Volumes remain far apart. According to McKinsey, cited by Eco, traditional payment systems process between $5 trillion and $7 trillion per day, against roughly $30 billion of stablecoin transactions. Compiled figures also indicate that some international remittances cost up to 20% of the amount transferred, and that typical card settlement leaves merchants waiting two to three business days for their funds. For Polygon, the SoFiUSD addition strengthens an activity already estimated at more than $3 trillion in cumulative stablecoin transfer volume, according to the company. Visa and Mastercard support stablecoin settlement on the network, while Stripe routes USDC payments for merchants in more than 150 countries.
Mastercard, Bullish and institutional adoption
The rollout has come in stages. On September 22, 2026, SoFi and Mastercard announced SoFiUSD settlement on Mastercard’s global payments network. SoFi is described as the first national bank to go live with stablecoin settlement on that network, and it is migrating its full card program to blockchain settlement. In October, SoFi launched SoFi Earn, a tokenized deposit convertible one-for-one into SoFiUSD and paying 4.40%, a product distinct from the stablecoin itself. In the third quarter, SoFi reported 503,000 “crypto products” and $161.6 million in gross revenue from crypto transactions, up 20% from the previous quarter.
On June 22, 2026, Bullish became the first centralized exchange to list SoFiUSD. Listed on the NYSE under BLSH, the platform pairs a limit order book with an automated liquidity creation mechanism that operates independently of price feeds and external oracles. Bullish says the model generates thousands of bids and offers to reduce slippage and keep spreads tight. The company recorded $30 billion in spot trading volume in May 2026. It is regulated or registered with the New York State Department of Financial Services, Germany’s BaFin, the Hong Kong Securities and Futures Commission and the Gibraltar Financial Services Commission, and Bullish Europe operates under MiCA.
“The first stablecoin issued by a US national bank is a defining moment for the entire market. Regulated institutions are no longer just watching digital assets from the sidelines; they are building on them.”
Tom Farley, CEO of Bullish
Reported reactions are mainly institutional. Sources provide no SoFiUSD price data, trading volume or liquidity levels on Polygon after launch, so conclusions about real-world usage would be premature. On the customer base, SoFi had introduced SoFiUSD to nearly 15 million members in May 2026, before Polygon cited more than 17 million in November. These figures reflect two stages of growth rather than conflicting scopes. Similarly, some outlets date the Solana launch to late 2025, while Eco’s detailed timeline places the Solana platform launch on April 2, 2026.
Outlook: three scenarios
The Polygon integration is less a technical breakthrough than a distribution test. It puts a cash-backed token issued by a national bank in front of a base of more than 17 million members, without requiring a separate wallet. SoFi also markets its white-label infrastructure so other banks and fintechs can issue their own stablecoins. Eco suggests this could cut time-to-market from several years to a few weeks.
Three scenarios stand out. In the bullish case, card and merchant settlement scales and white-label issuers multiply, pushing bank-issued dollar tokens into mainstream payments. In the base case, usage stays concentrated in institutional settlement and internal treasury flows, with gradual consumer adoption. In the bearish case, the absence of yield limits retail appetite, competition from USDC, USDT and PYUSD intensifies, and regulatory interpretation of the GENIUS Act tightens. Investors should track circulating supply, redemptions and independent reserve attestations rather than launch announcements alone.
