​Fig 1. The dollar looks identical onchain. What stands behind it does not.
​

sofiUSD and USDC are both dollar-denominated tokens that hold a 1:1 peg, but they differ at the layer most comparisons skip: who issues the token and what legal instrument backs it. sofiUSD is issued by SoFi Bank, N.A., an OCC-regulated, FDIC-insured national bank, and launched on December 18, 2025. USDC is issued by Circle, a non-bank payments company, and carries a circulating supply near $77 billion as of Q1 2026. One is a bank-issued dollar token. The other is a reserve-backed claim on a private issuer.
​

That distinction changes who you are exposed to when you hold the dollar, how redemption works, and whether deposit insurance is in the picture. This article compares the two by issuer, backing, redemption path, chain availability, and regulatory treatment, without rendering a verdict on which is better for any use.
​

The core difference is the issuer's legal form and the instrument behind the token. sofiUSD is a dollar token issued directly by a chartered national bank, with reserves held in SoFi Bank's account at the Federal Reserve. USDC is a dollar token issued by Circle, a regulated money-services business, backed by a segregated reserve of short-dated US Treasuries and cash held at commercial banks.
​

SoFi describes sofiUSD as the first stablecoin issued by a nationally chartered, FDIC-insured US bank on a public, permissionless blockchain, per the company's December 2025 launch announcement. That framing matters because a bank's dollar liability sits on the bank's own balance sheet, whereas Circle holds USDC reserves in a bankruptcy-remote structure separate from its operating business, detailed on Circle's transparency page.
​

The token mechanics look similar. Both are fungible ERC-20 tokens that transfer in seconds and settle around the clock. The divergence is institutional: a bank deposit versus a reserve fund claim. For background on how a chartered bank entering the stablecoin market reframes the category, see the pillar overview, SofiUSD Explained: How Bank-Issued Stablecoins Are Reshaping Digital Payments.
​

sofiUSD is issued by SoFi Bank, N.A., with BitGo providing the stablecoin-as-a-service infrastructure for minting, custody, and chain connectivity. Reserves sit as cash in SoFi's Federal Reserve account. USDC is issued by Circle, with reserves held roughly 80% in short-dated Treasuries through the SEC-registered Circle Reserve Fund and the remainder as cash at global banks.
​

SoFi's role is the substance here. Because SoFi Bank holds the reserve directly at the central bank, SoFi has stated the token carries no credit or liquidity risk on the issuer side, a claim repeated across coverage of the CoinDesk launch report. BitGo handles issuance plumbing under SoFi's regulated umbrella, as confirmed in Cointelegraph's coverage of the BitGo selection.
​

Circle's backing is verified differently. A Big Four firm, Deloitte, reviews Circle's reserve assertions monthly under AICPA agreed-upon-procedures attestation standards, confirming reserves meet or exceed USDC in circulation at each report date. The reserve composition and attestation cadence are documented at USDC's reserve explainer. The instruments differ: a central-bank cash balance versus a Treasury-heavy reserve fund.
​

sofiUSD behaves as both, depending on where it is held. On SoFi's own platform, SoFi treats it as a tokenized deposit, which means it can be eligible for FDIC insurance and interest. Held elsewhere, in a self-custody wallet or on a third-party exchange, it functions as a payment stablecoin with no insurance and no yield. The label flips with custody.
​

This dual treatment is the genuine analyst debate around sofiUSD. Ledger Insights reported that SoFi structured the token to act as a deposit token on-platform and a stablecoin off-platform, a design that blends two regulatory categories. The distinction is not cosmetic. As the Brookings Institution explains, a stablecoin moves the dollar off the bank's books as a claim on an issuer, while a tokenized deposit keeps it on the bank's balance sheet.
​

USDC carries no such ambiguity. It is a payment stablecoin in every venue, a claim on Circle's reserve rather than a deposit at any bank. For a deeper look at where sofiUSD sits on this spectrum, see Is sofiUSD a Stablecoin or a Tokenized Deposit? and the category explainer What Is a Tokenized Deposit?.
​

Redemption for sofiUSD routes back to SoFi Bank, which can settle the token against the bank's own dollar reserves at the Federal Reserve. Redemption for USDC routes to Circle, which converts tokens to dollars against its reserve fund, with mint and burn handled through Circle Mint accounts for verified institutional partners. Both target same-value, near-immediate settlement.
​

The practical difference is the counterparty you redeem against. A sofiUSD holder ultimately faces a chartered bank whose dollar sits at the central bank, which SoFi positions as immediate redemption without credit or liquidity friction, per the launch reporting from The Block. A USDC holder redeems against Circle's reserve, accessed at par through institutional Circle Mint relationships, while retail holders typically convert through exchanges.
​

Onchain, both tokens move identically: a transfer is a transfer. The redemption gateway is where the institutional structure reasserts itself. A USDC holder who needs dollars in a bank account converts at par through an exchange or a Circle Mint partner. A sofiUSD holder redeeming through SoFi settles against the bank directly, which is the mechanical consequence of the cash sitting in SoFi Bank's own master account at the Federal Reserve rather than in a separate fund. Moving either token across chains to reach a redemption venue is a routing problem, which is where infrastructure like Eco fits, covered in the final section.
​

sofiUSD launched on Ethereum as an ERC-20 token and added Solana for settlement, with enterprise availability rolling out through 2026. USDC is natively issued on a much broader set of chains, including Ethereum, Solana, Base, Arbitrum, Polygon, and more than a dozen others, with Circle's CCTP enabling native cross-chain transfer. USDC's footprint is currently far wider.
​

sofiUSD's Solana expansion arrived with SoFi's enterprise platform. On April 2, 2026, SoFi launched Big Business Banking, a regulated platform running fiat and crypto settlement on Solana, with launch participants including Mastercard, Galaxy, Wintermute, Cumberland, Fireblocks, and BitGo. USDC's multi-chain reach is documented across Circle's network coverage, spanning Solana's roughly $5.4 billion in TVL and Ethereum's $42.7 billion per DeFiLlama.
​

For a holder, this means USDC is available almost anywhere a dollar token is accepted, while sofiUSD is reaching chains in sequence. The gap reflects timing more than ambition: USDC has issued natively since 2018 and built CCTP to mint and burn across chains without wrapped representations, whereas sofiUSD is roughly five months old as of Q1 2026 and is expanding through SoFi's enterprise rollout rather than a retail-first scramble. sofiUSD's chain rationale is explored in sofiUSD on Solana, and its enterprise settlement model in sofiUSD for Business.
​

sofiUSD inherits national-bank supervision from the OCC and sits inside the bank's regulated balance sheet, which shapes its risk profile differently from a non-bank issuer. USDC is regulated as a payment stablecoin under frameworks like the GENIUS Act, signed July 2025, and Circle holds money-transmitter licensing. Neither token's offchain form carries FDIC deposit insurance.
​

The insurance point is widely misunderstood, so it is worth stating precisely. In March 2026, the FDIC confirmed that payment stablecoins receive no deposit insurance under the GENIUS Act, including pass-through coverage, with Acting Chairman Travis Hill summarizing the agency's stance that "a deposit is a deposit". So sofiUSD held in a wallet is uninsured, the same as USDC. Only sofiUSD held on SoFi's platform as a deposit token can be insurance-eligible, per the FDIC's GENIUS Act implementation proposal.
​

Both issuers operate under US oversight, but the supervisory anchor differs: a chartered bank regulator for SoFi, a payment-stablecoin and money-transmission regime for Circle. For how these regulatory tracks compare, see the framework piece MiCA vs the GENIUS Act. This section describes the structures factually and makes no assessment of which token is safer for any holder.
​

The table below summarizes the two dollars across the dimensions that actually diverge: issuer type, backing instrument, redemption counterparty, chain availability, and insurance treatment. Figures and classifications reflect publicly reported information as of Q1 2026.
​

sofiUSD's circulating supply is not reliably published as of Q1 2026, so the table marks it as not listed rather than estimating. The comparison shows USDC as the established, multi-chain, attestation-verified reserve dollar, and sofiUSD as the newer bank-native dollar whose deposit-token treatment is its defining structural trait. For more bank-issued dollars entering this field, see Bank-Issued Stablecoins 2026 and the JPM Coin comparison, sofiUSD vs JPM Coin.
​

Eco is stablecoin-routing infrastructure that moves dollar tokens across chains and abstracts the differences between issuers for the end user. Whether a payment originates in a bank-issued token like sofiUSD or a reserve-backed token like USDC, Eco routes the transfer to the destination chain and settlement venue without the user managing bridges manually.
​

The relevance to this comparison is the redemption-and-availability gap. sofiUSD reaches Ethereum and Solana today, while USDC spans more than a dozen chains across roughly $321 billion in total stablecoin supply per DeFiLlama. Routing infrastructure lets an application accept whichever dollar a counterparty holds and deliver it where it needs to settle, which matters as more bank-issued dollars enter circulation alongside established stablecoins. Eco connects these flows through cross-chain routing covered in the bank-issued stablecoins pillar.

Sources and methodology. Stablecoin supplies and chain TVL pulled from DeFiLlama in May 2026. sofiUSD facts verified against SoFi's December 2025 and April 2026 announcements; USDC reserve and supply figures against Circle transparency reporting. FDIC insurance treatment verified against the agency's March 2026 GENIUS Act statements. Figures refresh quarterly.
​

This article does not rank the two on safety. sofiUSD is a bank-issued token backed by cash SoFi Bank holds in its own master account at the Federal Reserve; USDC is backed by a Treasury-heavy reserve fund with monthly Deloitte attestation. Neither carries FDIC insurance when held offchain. The structures differ; the choice depends on the holder's needs.
​

Only when held as a deposit token on SoFi's own platform. Held in a self-custody wallet or on a third-party exchange, sofiUSD functions as a payment stablecoin with no FDIC insurance, the same status as USDC. The FDIC confirmed in March 2026 that payment stablecoins receive no deposit insurance under the GENIUS Act.
​

sofiUSD launched on Ethereum as an ERC-20 token and added Solana for enterprise settlement in April 2026. USDC is natively issued on Ethereum, Solana, Base, Arbitrum, Polygon, and more than a dozen other chains, with Circle's CCTP enabling native cross-chain transfer. USDC's chain footprint is currently much wider.
​

SoFi Bank, N.A., an OCC-regulated, FDIC-insured national bank, issues sofiUSD, with BitGo providing the stablecoin-as-a-service infrastructure for minting and custody. This makes SoFi the first nationally chartered US bank to issue a stablecoin on a public, permissionless blockchain, per SoFi's December 2025 announcement.
