sofiUSD for business is SoFi's enterprise settlement product, where the bank's fully reserved dollar token moves corporate payments onchain in real time instead of through ACH batches or wire cutoffs. On April 2, 2026, SoFi launched Big Business Banking, a single regulated platform that lets companies hold deposits, send and receive payments, and settle in either fiat or sofiUSD on public blockchains. The launch put sofiUSD at the center of SoFi's pitch to treasury teams: a digital dollar issued by a nationally chartered bank that settles 24 hours a day, 7 days a week.

This article covers what the Big Business Banking launch announced, which firms are onboard, how sofiUSD settlement compares to traditional ACH and wire rails, and the treasury use cases the platform targets. For the broader background on the token, see SofiUSD Explained: How Bank-Issued Stablecoins Are Reshaping Digital Payments.
​

SoFi announced Big Business Banking on April 2, 2026, describing it as a unified platform that lets companies hold large deposit balances, move money, and settle transactions in fiat or sofiUSD on a single regulated bank. The product runs on SoFi Bank, N.A., a nationally chartered institution with direct Federal Reserve access, and connects that regulated base to public blockchains so funds can move continuously rather than within banking-hour windows.
​

sofiUSD is the onchain settlement asset inside that platform. SoFi first launched the token on December 18, 2025, on Ethereum, calling it the first stablecoin issued by a US nationally chartered and insured deposit bank on a public, permissionless blockchain. The infrastructure runs through BitGo's stablecoin-as-a-service platform, which handles issuance and connects the token to payment providers, market makers, and exchanges. The token is issued 1:1 against the US dollar and backed by cash reserves held inside SoFi's regulated environment, with third-party attestations.
​

The core settlement mechanism is mint and burn. When a business funds a payment, SoFi mints sofiUSD against reserves; when funds are redeemed, the token is burned and the dollar balance is released. That lets a company convert between fiat and the onchain dollar instantly while the backing stays inside the bank. Because the platform sits on a chartered bank with Fed access rather than on a fintech wrapper, the fiat side of every conversion clears through regulated rails the issuer controls directly.
​

The Big Business Banking launch named a set of initial participants who will test and scale the platform. These are infrastructure and trading firms, not retail customers, which signals that SoFi is positioning sofiUSD as a settlement layer for other financial businesses rather than a consumer wallet token.
​

The announced participants include:

The presence of Mastercard is the most consequential for reach. A settlement currency that clears across a card network touches the businesses those issuers and acquirers serve, which extends sofiUSD's potential footprint well beyond firms that hold the token directly. The market-maker roster (Galaxy, Cumberland, Wintermute, B2C2) matters for a different reason: deep two-sided liquidity is what keeps an enterprise settlement token redeemable at par when a treasury needs to convert size on demand.
​

The case SoFi makes for sofiUSD is structural, not cosmetic. Traditional US payment rails carry built-in timing constraints that an onchain dollar removes.
​

Standard ACH transfers clear in one to three business days and run only on banking days. Wires initiated after a bank's daily cutoff move the next business day, and weekends and holidays push time-sensitive payments further out. Both rails impose reconciliation friction because the money and the confirmation arrive on different schedules. sofiUSD settlement, by contrast, finalizes onchain in seconds to minutes and runs 24/7/365, with no cutoff and no banking-day calendar.
​

SoFi paired the Big Business Banking launch with FedNow access, which gives the fiat side of the platform instant clearing during US hours as well. The combination matters: a treasury team can keep balances at the bank, settle domestic fiat instantly through FedNow, and move onchain in sofiUSD when a counterparty, a card network, or a weekend window calls for it. The difference from a non-bank stablecoin is that both the fiat leg and the token leg sit inside one chartered institution, so conversions do not route through a separate banking partner.
​

The trade-off worth naming is reach versus maturity. ACH and Fedwire connect to every US bank account; sofiUSD connects to counterparties who can hold and redeem the token. For closed loops between participating firms, the onchain rail is faster and always on. For paying an arbitrary supplier who banks elsewhere, traditional rails or an off-ramp back to fiat are still part of the flow.
​

Cost is the other axis. Wire fees run several dollars to tens of dollars per transfer, and ACH carries per-item and return-handling costs that add up at volume. Onchain settlement collapses the per-transfer fee to network gas, which on Solana is a fraction of a cent and on Ethereum varies with congestion. For a treasury moving thousands of payments a month, the fee profile shifts the unit economics, which is part of why SoFi expanded sofiUSD to a low-cost chain rather than keeping it Ethereum-only. The cost case only holds, though, when the funds stay onchain; every conversion back to fiat reintroduces a banking-rail step.
​

There is also a finality difference that treasury operators care about. An ACH credit can be returned for days after it posts, which keeps a payment provisional well past the moment it appears. A wire is final once sent but slow to initiate. Onchain settlement gives both properties at once: a sofiUSD transfer is final at network confirmation and irreversible from that point, which removes the return-window ambiguity that complicates reconciliation on ACH.
​

sofiUSD launched on Ethereum in December 2025 and expanded to Solana in 2026 for the enterprise settlement push. SoFi cited Solana's low transaction costs, settlement speed, and throughput as the reasons it suits payment infrastructure at business scale, where fee-per-transaction and finality time directly affect unit economics.
​

The two-chain footprint is deliberate. Ethereum gives sofiUSD reach into the deepest pool of onchain liquidity, DeFi venues, and institutional custody tooling. Solana gives it the cost profile a card network or a high-volume payments flow needs when individual transactions are small and frequent. Per the build brief and verified sources, sofiUSD is live on Ethereum and Solana; SoFi has not announced additional chains as of this writing. For the deeper reasoning on the chain choice, see sofiUSD on Solana: Why SoFi Chose Solana for Settlement.
​

A multi-chain settlement token raises an operational question for the businesses using it: how do funds move between the chains where counterparties actually hold balances? A payment that originates on Solana but needs to land with a counterparty holding Ethereum sofiUSD requires either an issuer-side bridge or a routing layer that abstracts the chain difference away from the treasury operator.
​

For a corporate treasury, the appeal of sofiUSD is operational control over timing. Three use cases follow directly from the always-on settlement model.
​

Liquidity rebalancing. Treasury teams can move balances between accounts, desks, and counterparties on weekends and after hours without waiting for the next banking day. A position that would otherwise sit idle from Friday cutoff to Monday open can be redeployed continuously.
​

Counterparty and exchange settlement. Trading desks and exchanges that hold sofiUSD can settle obligations between each other in seconds, which reduces the intraday credit exposure that builds up when settlement lags execution. This is the use case the market-maker participants (Galaxy, Cumberland, Wintermute, B2C2) are positioned to test first.
​

Card and merchant settlement. Through the Mastercard partnership, sofiUSD can act as a settlement currency between card issuers and acquirers, letting the businesses on those networks receive funds on a 24/7 schedule rather than on card-network batch cycles.
​

The constraint on all three is that sofiUSD is a settlement asset for participating firms, not a general-purpose payment method for any supplier. Treasury teams adopting it are building closed-loop or networked flows with counterparties who also hold the token, then bridging to fiat at the edges where they need to reach the broader banking system.
​

The reserve model shapes how a treasury should think about the holding itself. Because sofiUSD is fully reserved against cash inside SoFi Bank, N.A., the balance a company holds is a claim on a chartered, FDIC-insured institution rather than on a money-market portfolio or a basket of commercial paper. That changes the risk question from "what is backing this token" to "what is the credit and operational standing of the issuing bank," which is a more familiar assessment for a corporate treasurer than parsing a reserve-attestation report. Whether that makes sofiUSD a stablecoin or a tokenized deposit is a live debate among analysts, and the answer affects which regulatory regime applies.
​

A practical treasury adoption path tends to run in three stages. First, a firm holds a working balance of sofiUSD to settle with a single counterparty already on the platform, proving out the onchain leg against a known relationship. Second, it expands to the network of participating firms, so a single token balance settles obligations across several desks and providers. Third, where the Mastercard relationship reaches, it begins using sofiUSD as a settlement currency into the card network rather than only between named counterparties. Each stage widens the closed loop without requiring the treasury to abandon its existing fiat rails.
​

A bank-issued settlement token that lives on more than one chain creates a routing problem that the treasury operator should not have to solve by hand. Eco is stablecoin settlement infrastructure: it routes dollar-denominated value across chains so that a balance held in one place can settle a payment that needs to land in another, without the sender managing bridges, gas, or chain selection manually.
​

For an enterprise using a multi-chain settlement asset like sofiUSD on Ethereum and Solana, that routing layer is what turns two separate balances into one spendable pool. Eco's settlement and treasury POV is that the chain a dollar happens to sit on should be an implementation detail, not a decision a finance team makes per transaction. As bank-issued tokens and reserve-backed stablecoins proliferate across chains, the operators moving them need infrastructure that abstracts the plumbing and settles to the right place on demand.
​

It is debated. SoFi brands sofiUSD as a fully reserved stablecoin, but its cash-only backing and on-demand redemption from a chartered bank lead some analysts to classify it closer to a tokenized bank deposit. The label affects how it is regulated and how its risk is assessed. The cluster pillar covers this classification question in more detail.
​

The Big Business Banking launch on April 2, 2026, targets enterprises, fintechs, and other banks first. SoFi has indicated consumer access is planned, but the enterprise settlement product is the live, named launch as of this writing. Treat any consumer timeline as conditional until SoFi confirms it.
​

sofiUSD launched on Ethereum in December 2025 and expanded to Solana for the enterprise settlement push. As of this writing, those are the two chains SoFi has announced. SoFi has said it plans to expand cross-chain over time.
​

sofiUSD is issued directly by a nationally chartered, FDIC-insured bank with Federal Reserve access, so both the fiat and onchain legs of a conversion sit inside one regulated institution. USDC and USDT are issued by non-bank companies (Circle and Tether) and rely on separate banking partners for the fiat side. For a structural comparison, see the cluster's sofiUSD vs USDC article.
