sofiUSD on Solana is the second blockchain deployment of SoFi Bank's fully reserved dollar stablecoin, announced alongside the SoFi Big Business Banking platform on April 2, 2026. SoFi launched sofiUSD as an ERC-20 token on Ethereum in December 2025, then chose Solana for its enterprise settlement layer, citing transaction cost, settlement speed, and throughput. The token now lives on Ethereum and Solana only.
​

The expansion matters because sofiUSD is the first stablecoin issued by a US nationally chartered, FDIC-insured bank on a public, permissionless chain. When a regulated bank picks a settlement network, the choice signals where it expects high-volume institutional money movement to run. Ben Reynolds, SoFi's head of big business banking, framed Solana as "the right chain to use for payments, partially because of the cost, partially because of the settlement speed and ultimately the throughput," per The Block.
​

sofiUSD on Solana is the Solana-based version of SoFi Bank's dollar stablecoin, deployed to power 24/7 enterprise settlement under the Big Business Banking platform launched April 2, 2026. The token keeps its 1:1 dollar backing and bank issuance; only the settlement rail changes. sofiUSD remains live on two chains, Ethereum and Solana, with no other networks announced as of May 2026.
​

SoFi first issued sofiUSD in December 2025 as an ERC-20 token on Ethereum, backed 1:1 by cash SoFi Bank holds in its own master account at the Federal Reserve, per SoFi's launch release. The issuance infrastructure runs on BitGo's stablecoin-as-a-service platform, announced March 2026. Adding Solana extends the same reserve and redemption model onto a second venue rather than spinning up a separate token.
​

The distinction between chain and issuer matters here. The issuer is SoFi Bank, N.A., an Office of the Comptroller of the Currency regulated depository institution. The chains are infrastructure. A reader holding sofiUSD on Solana holds the same bank liability as a holder on Ethereum, redeemable at the same bank. That separation is what lets a bank-issued coin span multiple networks without fragmenting its backing.
​

SoFi positions the token as settlement infrastructure for other banks, fintechs, and enterprise platforms, not just a consumer product. The FinTech Futures coverage of the December 2025 launch described sofiUSD as a stablecoin-as-a-service play, with SoFi acting as the regulated issuer and other institutions plugging into it. The Solana deployment is the rail those institutions will most likely settle on when speed and cost dominate the decision.
​

SoFi chose Solana for settlement because of three properties its leadership named directly: low transaction cost, fast settlement finality, and high throughput. Solana processes thousands of transactions per second with sub-second finality and per-transaction fees often under a cent, which suits the high-frequency, low-margin money movement that crypto trading desks and payment networks generate. Ethereum's base-layer economics work against that use pattern.
​

The cost gap is the clearest driver. Ethereum mainnet gas fees fluctuate with network demand and routinely run dollars per transaction during busy periods, while Solana's fees sit near $0.00025 in normal conditions per Solana's documentation. For an enterprise settling thousands of transfers a day, that difference compounds into a material operating expense. A bank running settlement infrastructure has to account for it.
​

Speed is the second factor. Solana targets sub-second slot times and finality measured in seconds, whereas Ethereum finality under its proof-of-stake design takes roughly 13 minutes for full economic finality. For a platform marketing 24/7/365 real-time settlement, waiting minutes per transaction undercuts the pitch. SoFi describes letting a trading firm deposit dollars, mint sofiUSD, and deploy capital "instantly into markets," per CoinDesk.
​

Throughput is the third. Solana sustains thousands of transactions per second at the base layer without relying on rollups, which matters for a settlement network expecting institutional flow. SOL carried a market capitalization near $48.3B and Solana held roughly $5.4B in DeFi TVL as of late May 2026, per DeFiLlama, reflecting a mature venue with real liquidity rather than a speculative testbed.
​

sofiUSD settlement on Solana runs on a mint-and-burn model inside SoFi's regulated bank. A company deposits US dollars, SoFi mints an equivalent amount of sofiUSD against reserves, and the tokens move onchain on Solana for near-instant settlement. To exit, the company redeems sofiUSD and SoFi burns the tokens, returning dollars. Reserves stay within the bank throughout.
​

This is the foundational capability of the Big Business Banking platform, which provides what SoFi calls 24/7/365 money movement across fiat, sofiUSD, and select cryptocurrencies from a single nationally chartered bank, per the April 2, 2026 launch announcement. The mint-and-burn flow is what lets a deposit become a transferable onchain dollar and revert to a bank balance without leaving the regulated perimeter.
​

The early participant list shows the intended traffic. SoFi named Mastercard, Cumberland, Wintermute, Galaxy, BitGo, Fireblocks, B2C2, Jupiter, Mesh Payments, and Bullish as initial partners, per Coinpedia. Most are trading firms, market makers, and custodians that move large dollar volumes and need settlement faster than the wire-and-ACH cutoff windows allow.
​

​

A concrete example clarifies the value. Mastercard agreed to use sofiUSD for settlement across its global network, per CoinDesk's coverage. Card-network settlement traditionally clears on legacy rails with multi-day lag and limited operating hours. Routing it through a bank-issued stablecoin on Solana collapses that to near-instant, around the clock.
​

The trading-firm case is just as direct. Cumberland, Wintermute, and B2C2 are market makers that hold inventory and move capital between venues continuously. A wire that settles next business day forces them to pre-fund positions or hold idle balances. Minting sofiUSD against a SoFi deposit and settling on Solana in seconds lets that capital stay productive, which is the operational reason a trading desk would route flow through a bank coin rather than a wire.
​

For a bank-issued stablecoin, Ethereum offers the deepest stablecoin liquidity and the widest institutional tooling, while Solana offers lower cost, faster finality, and higher throughput. SoFi did not pick one over the other. It issues on Ethereum for reach and composability and added Solana for settlement performance, so the trade-off is resolved by running both rather than choosing.
​

Ethereum hosts the largest concentration of stablecoin value. USDC and USDT together exceed $265B in supply, the bulk of it on Ethereum and its rollups, per DeFiLlama. That depth matters for any token that wants to integrate with existing DeFi, custody, and treasury systems. A bank issuing only on Solana would cut itself off from that base layer of integrations.
​

Solana wins on the settlement metrics that high-frequency enterprise flow cares about. The table below compares the two chains on the dimensions SoFi's leadership named when explaining the Solana decision.
​

The pattern is not unique to SoFi. PYUSD, PayPal's stablecoin, launched on Ethereum then expanded to Solana for the same cost and speed reasons, and USDC has been native to Solana for years. Bank-issued and corporate stablecoins increasingly treat Ethereum as the integration hub and Solana as a high-throughput payment rail, two roles that complement rather than compete.
​

Multi-chain issuance means sofiUSD exists as the same bank liability on two separate networks, so moving value between Ethereum and Solana is not a simple onchain transfer. The two deployments are distinct token contracts. Moving sofiUSD across chains requires either redemption and reissuance through SoFi, or a cross-chain routing layer that handles the transfer for the holder.
​

This is the practical friction of any multi-chain stablecoin. A holder with sofiUSD on Ethereum cannot send it directly to a Solana wallet; the Ethereum token and the Solana token are not the same onchain asset even though they represent the same dollar claim. The same constraint applies to USDC, which Circle addresses with its Cross-Chain Transfer Protocol, and to USDT across its deployments.
​

The redemption-and-reissuance route works but is slow and bank-gated: a holder redeems on one chain, waits for SoFi to process, then receives fresh tokens on the other. That defeats the speed advantage Solana was chosen for in the first place. A routing layer keeps the transfer onchain and continuous, sourcing liquidity on the destination chain so the holder receives value in seconds rather than routing back through the issuer's redemption queue. The choice between the two paths is the difference between treating the bank as a settlement bottleneck and treating the chain boundary as something the infrastructure handles automatically.
​

Cross-chain routing infrastructure exists to close that gap. Eco operates a stablecoin routing layer that moves dollar-denominated value across chains, and it supports both Solana and Ethereum, the two networks where sofiUSD lives. For a treasury or payment platform holding a bank coin on one chain that needs liquidity on the other, a routing layer abstracts the chain boundary so the dollar is the unit that matters, not the network it currently sits on.
​

No. The chain sofiUSD settles on does not change its regulatory status, because the regulated entity is SoFi Bank, N.A., not the network. Whether a token sits on Ethereum or Solana, it remains a liability of an OCC-supervised, FDIC-insured national bank, backed by cash SoFi Bank holds in its own master account at the Federal Reserve. The blockchain is a settlement venue; the legal claim sits with the bank.
​

This is a meaningful contrast with reserve-backed stablecoins from non-bank issuers. SoFi is the first nationally chartered US bank to issue a stablecoin on a public, permissionless chain, per its launch statement. The reserves back the token 1:1 in cash that SoFi Bank holds primarily in its own master account at the Federal Reserve rather than in a separate money-market structure, which is part of why some analysts debate whether sofiUSD is better described as a tokenized deposit.
​

The broader framework comes from the GENIUS Act, signed into law in July 2025, which established federal rules for payment stablecoins in the United States. SoFi's bank charter and the act together place sofiUSD inside the regulated banking perimeter on both chains. Adding Solana does not move it outside that perimeter; it extends a bank-supervised instrument onto a second public ledger. For the classification debate in full, see the companion article on whether bank-issued stablecoins like sofiUSD behave more like deposits than reserve-backed coins.
​

sofiUSD on Solana matters because it puts a regulated US bank's settlement infrastructure on a high-throughput public chain, validating Solana as a venue for institutional dollar movement. It also raises the cross-chain question for anyone building on bank coins: value will land on whichever chain a given counterparty uses, and moving it requires routing that spans Ethereum and Solana.
​

For payment and treasury operators, the takeaway is that liquidity now fragments across chains by design. A bank issues on Ethereum for integration depth and on Solana for settlement speed, and the holder ends up needing both. Eco's routing layer addresses exactly that fragmentation, moving stablecoin value across Solana, Ethereum, and other supported chains so applications treat the dollar as one balance rather than several chain-specific pools.
