SoFi's bank-issued stablecoin adds Polygon, in a launch announced by Polygon itself

SoFiUSD, the dollar-pegged token issued by SoFi Bank, N.A., is now live on Polygon's Open Money Stack, adding a third blockchain to the Ethereum and Solana deployments it already ran on. The expansion was disclosed Thursday, 12 November, in a statement from Polygon Labs that was reported by both The Block and Decrypt. Worth noting up front: the news originates with Polygon Labs — the company whose infrastructure is doing the onboarding — not with an independent filing or a neutral third party.

What actually changed

The mechanical change is narrow. SoFiUSD now runs on Polygon's Open Money Stack, which Decrypt describes as a payments layer bundling fiat on- and off-ramps, embedded wallets and cross-chain settlement into a single integration. Per Polygon Labs, SoFi's "more than 17 million members" can buy, sell, hold and convert SoFiUSD on Polygon directly in the SoFi app, without opening a separate crypto wallet or manually bridging between chains. On the stack, SoFiUSD joins Circle's USDC, Tether's USDT and PayPal's PYUSD.

Both outlets carry the same quote from Polygon Labs CEO Marc Boiron: "SoFi is well positioned to bring stablecoins into mainstream finance because it combines the regulatory foundation of a national bank with the reach of a major consumer and enterprise technology platform." That is the CEO of the platform booking the integration praising the integration — attributed opinion, not independent assessment.

The token itself

SoFiUSD is issued by SoFi Bank, N.A., which The Block and Decrypt both identify as regulated by the Office of the Comptroller of the Currency (OCC), and is redeemable one-to-one for U.S. dollars. Decrypt and Polygon's framing call it "the first stablecoin issued by a U.S. national bank" — a superlative that traces to interested parties (SoFi and Polygon), and one neither outlet independently sourced.

One disclosure appears in Decrypt but not in The Block, and it matters: SoFiUSD "is a payment stablecoin, not a bank deposit, and is not FDIC- or SIPC-insured, bank-guaranteed or legal tender." So despite the "bank-issued" headline doing the marketing work, the token carries none of the deposit protections a reader might associate with a national bank. The "one-to-one redeemable" claim is a SoFi representation, not an insured guarantee.

How it fits SoFi's wider crypto build-out

The Polygon listing is the latest in a run of SoFi digital-asset moves. Per Decrypt, SoFi launched SoFiUSD late last year — late 2025 — across Ethereum and Solana. In SoFi's third-quarter report last month, the company said it held 503,000 crypto products at quarter-end and that gross crypto transaction revenue reached $161.6 million, up 20% from the prior quarter (The Block, citing SoFi's own figures). Those are the issuer's numbers, not independently verified.

The two outlets differ slightly on the card program. The Block says that in September the bank "began settling card transactions using its stablecoin on Mastercard's network." Decrypt states more sweepingly that SoFiUSD "already settles the company's entire card program over Mastercard's network." The reconciled read: card settlement via SoFiUSD on Mastercard began around September and has since been described (by SoFi/Polygon) as covering the full card program; the exact current scope isn't independently confirmed.

On the tokenized-deposit product, The Block says SoFi launched it in October, letting customers convert deposits into SoFiUSD one-to-one. Decrypt names it "SoFi Earn" and adds a figure The Block omits: it pays 4.40% yield and converts one-to-one into SoFiUSD. The Block also notes that the Mastercard settlement move came "weeks after agreeing to connect its SoFi Exchange Network with Kraken's infrastructure."

Why Polygon wants this

For Polygon, the pitch is its payments franchise. Decrypt reports — "according to the company," i.e. Polygon's own figure — that the network has processed more than $3 trillion in lifetime stablecoin transfer volume. Decrypt adds that Visa and Mastercard support stablecoin settlement on Polygon, and that Stripe uses it to route USDC payments for merchants in more than 150 countries. Polygon also recently extended Open Money Stack to Solana, per Decrypt. Adding a bank-issued dollar token to that stack is a credibility and distribution win for Polygon — which is precisely why Polygon, not SoFi, is the party putting out the statement.

Key facts

• SoFiUSD is now live on Polygon Open Money Stack, adding Polygon to its existing Ethereum and Solana support (The Block, Decrypt, via Polygon Labs statement, 12 Nov 2026).
• Issued by SoFi Bank, N.A., OCC-regulated; redeemable 1:1 for USD; joins USDC, USDT and PYUSD on the stack (both outlets).
• Not FDIC- or SIPC-insured, not bank-guaranteed, not legal tender (Decrypt).
• SoFi reported 503,000 crypto products and $161.6M gross crypto transaction revenue in Q3, up 20% quarter-on-quarter (The Block, citing SoFi).
• Tokenized deposit product — "SoFi Earn" — launched October, pays 4.40% yield, converts 1:1 into SoFiUSD (The Block for timing, Decrypt for yield/name).
• SoFiUSD began settling card transactions on Mastercard's network around September (The Block); Decrypt says it now settles "the entire card program."
• Polygon claims $3 trillion+ lifetime stablecoin transfer volume; Stripe routes USDC on Polygon in 150+ countries (Decrypt, citing Polygon).

The real-world read

The thing to hold onto is who is talking. This is a Polygon Labs announcement, reported by two secondary outlets who both attribute it to that statement. There is no primary filing, no independent on-chain confirmation of adoption, and no neutral third party in the chain. The Boiron quote and the "mainstream finance" framing are the vendor selling its own rails.

The most important missing number is SoFiUSD's actual size. Nowhere in either report is there a circulating supply, market cap, or on-chain volume for SoFiUSD itself. We get SoFi's broad crypto revenue (503,000 products, $161.6M — the issuer's own figures) and Polygon's $3 trillion lifetime stablecoin total (Polygon's own figure), but nothing that sizes how much SoFiUSD is in use. Adding a third chain to a token whose circulation isn't disclosed is a distribution announcement, not an adoption milestone.

The "bank-issued" positioning cuts both ways. It lends regulatory gloss — and it is accurate that SoFi Bank is OCC-regulated — but Decrypt's disclosure that SoFiUSD is not FDIC- or SIPC-insured and is not a deposit is the fact the marketing glides past. A reader hearing "stablecoin from a national bank" could reasonably, and wrongly, assume deposit-grade protection. The Block's write-up omits that disclaimer entirely, which is exactly the kind of gap that lets the "bank" framing do unearned work.

The two card-program descriptions don't fully agree — "began settling" (The Block) versus settles "the entire card program" (Decrypt) — and neither is independently confirmed. The honest statement is that SoFiUSD is being used in card settlement on Mastercard at some scale that the companies describe, and that the exact current coverage isn't verified here.

Opinion, and whose

• Marc Boiron, CEO of Polygon Labs: SoFi is "well positioned to bring stablecoins into mainstream finance" by combining a national bank's regulatory footing with a large tech platform's reach (quoted in both outlets). This is the integration partner's view of the integration.
• Decrypt's framing that stablecoins are moving "beyond crypto trading into the plumbing" of card settlement, business payouts and cross-border transfers is the outlet's own characterization of the trend, not a sourced fact.
• No forecasts, price targets, or adoption projections for SoFiUSD were offered by either outlet — a notable absence given the promotional tone of the underlying announcement.

Sources

• The Block (Tier 2, secondary), "SoFiUSD goes live on Polygon as bank-issued stablecoin expands reach," 12 Nov 2026 — reported the Polygon listing, the OCC-regulated issuer detail, SoFi's Q3 crypto figures ($161.6M, 503,000 products), October tokenized-deposit launch, September Mastercard settlement, and the Kraken infrastructure tie-up. Based on a statement Polygon Labs shared with the outlet — i.e. the primary source is an interested party's announcement.
• Decrypt (Tier 2, secondary), "SoFi Brings Its Bank-Issued Stablecoin to Polygon's Payments Stack," 12 Nov 2026 — reported the same listing, the "first stablecoin from a U.S. national bank" claim, the SoFi Earn 4.40%-yield tokenized deposit, Polygon's $3 trillion lifetime-volume and Stripe/Visa/Mastercard detail (attributed to Polygon), and — uniquely — the disclosure that SoFiUSD is not FDIC/SIPC-insured or a bank deposit. Also sourced to the Polygon Labs statement.

Both pieces anchor to a single originating source — a Polygon Labs statement — so several headline figures (circulation, $3T volume, revenue) come from interested parties and are attributed as such above.
