Stablecoin Issuer Directory: Who Backs Your Digital Dollars

Stablecoin Issuer Overview

Every stablecoin has an issuer behind it: a company, protocol, or DAO responsible for minting tokens, managing reserves, and honoring redemptions. The issuer's corporate structure, regulatory status, and audit practices determine whether your digital dollars are actually safe. This directory profiles the six most significant stablecoin issuers operating today and compares them across the dimensions that matter most.

For a side-by-side comparison of the stablecoins themselves, see the stablecoin comparison tool. This directory focuses on the entities behind each token.

Circle (USDC)

Circle Internet Group is a Delaware-incorporated company that went public on the NYSE under ticker CRCL in June 2025, raising approximately $1.1 billion at a $31 per share IPO price. USDC is issued and redeemed by Circle Internet Financial, LLC (US) and Circle Internet Financial Europe SAS (EU). Circle is the only major stablecoin issuer currently listed on a US stock exchange, which subjects it to SEC reporting requirements and public financial disclosures.

Circle holds state money transmitter licenses across the US and was the first company to receive a BitLicense from the NYDFS in 2015. In December 2025, Circle received conditional approval from the OCC to establish First National Digital Currency Bank, N.A., a federally regulated trust bank that would manage USDC reserves. Circle also holds e-money licenses in the EU under MiCA, making it the only major issuer with compliant dollar and euro stablecoins in Europe.

USDC reserves are held primarily in the Circle Reserve Fund (ticker: USDXX), an SEC-registered 2a-7 government money market fund managed by BlackRock. The fund holds cash, short-dated US Treasuries, and overnight Treasury repurchase agreements. Deloitte provides monthly attestation reports confirming that reserve value exceeds USDC in circulation, following AICPA attestation standards. BlackRock publishes daily portfolio disclosures independently.

Tether (USDT)

Tether is the largest stablecoin issuer by market capitalization, with USDT reaching approximately $184 billion in circulation as of early 2026. The corporate structure is complex: Tether Holdings, S.A. de C.V. is the parent company, now domiciled in El Salvador following a January 2025 relocation from the British Virgin Islands. The parent is ultimately owned by iFinex Inc., which also owns the Bitfinex cryptocurrency exchange. CEO Paolo Ardoino leads day-to-day operations, while co-founder Giancarlo Devasini serves as Chairman.

Tether's regulatory status is less straightforward than Circle's. The company is licensed by El Salvador's National Commission of Digital Assets (CNAD) and maintains BVI-incorporated subsidiaries. Tether paid an $18.5 million settlement to the New York Attorney General in 2021 over reserve misrepresentation claims. In September 2025, Tether announced plans for USAT, a US-regulated stablecoin designed to comply with the GENIUS Act.

Tether's Q4 2025 attestation (prepared by BDO) reports $193 billion in total reserve assets against $186.5 billion in liabilities, leaving $6.3 billion in excess reserves. The portfolio includes $122.3 billion in US Treasury bills, $19.3 billion in overnight reverse repos, $12.9 billion in gold, $9.9 billion in Bitcoin, and $14.6 billion in secured loans. BDO provides quarterly attestations (not full audits), each representing a single-day snapshot. Tether has never completed a comprehensive third-party audit.

Paxos (PYUSD, USDP, USDG)

Paxos Trust Company is a New York-based financial technology company founded in 2012 by Charles Cascarilla and Rich Teo. Paxos received the first limited-purpose trust charter for digital assets from the NYDFS in 2015, meaning every aspect of its operations is supervised by one of the strictest financial regulators in the United States. Paxos has also received conditional approval from the OCC to convert to a federal trust.

Paxos issues three stablecoins: USDP (Pax Dollar, launched 2018), PYUSD (PayPal USD, issued in partnership with PayPal), and USDG (Global Dollar, issued through Paxos Digital Singapore). PYUSD is integrated into PayPal's ecosystem, giving it distribution across one of the world's largest payment platforms. All three stablecoins are fiat-backed and redeemable 1:1 for US dollars.

Reserves for USDP and PYUSD are held in cash, US Treasury bills, and reverse repurchase agreements with regulated custodians. KPMG provides monthly attestation reports (replacing the prior attestor as of February 2025), conducted under AICPA standards. In August 2025, Paxos reached a $48.5 million settlement with the NYDFS related to compliance failures from its former BUSD partnership with Binance, though the company successfully wound down over $16 billion in BUSD without a depeg event.

Sky, Formerly MakerDAO (DAI, USDS)

MakerDAO rebranded to Sky in August 2024 and introduced USDS as the successor to DAI. The protocol completed its Endgame transition in May 2025, retiring the MKR governance token in favor of SKY (at a 1:24,000 conversion ratio). DAI remains active with approximately $5.4 billion in circulation, while USDS has grown to roughly $21 billion in supply as of early 2026.

Unlike every other issuer in this directory, Sky has no corporate entity, no headquarters, and no CEO. Governance decisions are made by SKY token holders through on-chain voting. This makes DAI and USDS the only major stablecoins without centralized issuer risk, but it also means there is no regulated entity standing behind the token and no single party accountable for reserve management.

DAI and USDS are backed by overcollateralized crypto loans: users deposit ETH, stETH, USDC, and other assets into vaults that must maintain collateral ratios of 150% or higher. The protocol also allocates roughly $948 million (about 14% of reserves) to real-world assets including US Treasuries held through off-chain trustees. All crypto collateral is verifiable on-chain in real time, though the RWA portion reintroduces trust assumptions similar to fiat-backed models.

First Digital (FDUSD)

First Digital Labs is the Hong Kong-based company behind FDUSD, which launched with strong growth on Binance before declining from a peak of approximately $4.4 billion in market cap (April 2024) to roughly $920 million by early 2025. In a notable structural change, FDUSD issuance transitioned from FD121 Limited (Hong Kong) to FD121 (BVI) Limited, while custody continues to be provided by First Digital Trust Limited in Hong Kong.

Hong Kong's Stablecoins Ordinance took effect on August 1, 2025, establishing a licensing framework under the HKMA. As of early 2026, the HKMA has not yet issued any stablecoin licenses, with the first expected in Q1 2026. First Digital plans to go public through a SPAC merger with CSLM Digital Asset Acquisition Corp III on the NYSE.

FDUSD reserves consist primarily of US Treasury bills, with smaller allocations to repo facilities and fixed deposits, held by qualified custodians at regulated depository institutions. First Digital publishes monthly reserve reports. The issuer faced a public dispute in April 2025 when Justin Sun accused First Digital Trust of mismanaging TrueUSD reserves, leading to a brief depeg. First Digital denied the allegations and filed a defamation claim. A Dubai court issued a worldwide freezing order covering $456 million in assets tied to the dispute.

Flashnet via Brale (USDB)

USDB is the first regulated, USD-backed stablecoin built natively for Bitcoin. Unlike the other issuers in this directory, USDB's structure separates the product company from the issuing entity: Flashnet designed and operates the USDB product, while Brale, a US-regulated financial entity, handles actual token issuance and reserve custody. This separation means Flashnet never touches the reserves directly.

USDB is issued 1:1 on Spark, a Bitcoin-native layer-2 protocol compatible with the Lightning Network. Reserves are backed by US Treasury bills, with no rehypothecation, lending, or fractional reserves. USDB is the only stablecoin in this directory that operates natively on Bitcoin without requiring bridges or wrapped tokens on other chains.

For Bitcoin holders, USDB serves a unique role: it enables native dollar-denominated trading pairs, on-chain treasury management, and instant stablecoin transfers without leaving the Bitcoin ecosystem.

Reserve Composition Compared

The quality and transparency of reserves varies dramatically across issuers. The following table breaks down what actually backs each stablecoin.

Tether stands out for holding non-traditional reserve assets including gold and Bitcoin, which introduces commodity and crypto price risk into what is marketed as a dollar-pegged instrument. Circle and Paxos maintain the most conservative reserve profiles, limited to Treasuries, cash, and repos. Sky's reserves are primarily crypto collateral verified on-chain, with a growing but still minority allocation to traditional assets.

How to Evaluate a Stablecoin Issuer

When assessing the entity behind a stablecoin, focus on these dimensions:

• Regulatory jurisdiction: is the issuer supervised by a recognized financial regulator (NYDFS, OCC, HKMA, MAS), or does it operate from a lighter-touch jurisdiction?
• Audit vs. attestation: monthly attestations from a Big Four firm (Deloitte, KPMG) provide stronger assurance than quarterly snapshots from smaller firms. No issuer has completed a full comprehensive audit.
• Reserve composition: 100% Treasuries and cash is the gold standard. Secured loans, gold, and Bitcoin introduce additional risk vectors.
• Corporate transparency: publicly traded issuers (Circle) face SEC reporting requirements. Private issuers vary widely in disclosure.
• Redemption infrastructure: can you redeem tokens directly with the issuer for dollars? Circle and Paxos offer direct redemption. Tether has minimum redemption thresholds.
• Chain support: does the issuer deploy natively on the chains you need? USDT and USDC cover 16+ networks. USDB serves the Bitcoin ecosystem via Spark.

Regulatory Landscape in 2026

The regulatory environment for stablecoin issuers shifted significantly in 2025. In the United States, the GENIUS Act (signed July 2025) established the first federal framework for payment stablecoins, requiring 1:1 reserves in cash, insured deposits, or short-term Treasuries, monthly attestations examined by a PCAOB-registered firm, and personal certification by the issuer's CEO and CFO. Both Circle and Paxos have pursued OCC trust charters to operate under this framework.

In the EU, the MiCA regulation continues to apply specific requirements to asset-referenced tokens and e-money tokens. Circle remains the only major global issuer with MiCA-compliant stablecoins. In Hong Kong, the Stablecoins Ordinance took effect in August 2025, with the HKMA expected to issue its first licenses in early 2026. Singapore's MAS stablecoin framework is expected to take effect mid-2026.

Frequently Asked Questions

Who is the largest stablecoin issuer?

Tether is the largest stablecoin issuer by market capitalization, with USDT at approximately $184 billion as of early 2026. Circle's USDC is second at roughly $77 billion. However, USDC has been growing faster, with its market cap increasing 73% in 2025 compared to USDT's 36% growth. USDC has also surpassed USDT in on-chain transaction volume, reaching $1.26 trillion in February 2026 versus USDT's $514 billion.

Which stablecoin issuers are regulated in the United States?

Circle and Paxos are the two major US-regulated stablecoin issuers. Circle holds state money transmitter licenses and has received conditional OCC approval for a national trust bank charter. Paxos holds a NYDFS limited-purpose trust charter and has also received conditional OCC approval. Brale, which issues USDB for Flashnet, is also a US-regulated entity. Tether is not regulated in the US but has announced plans for a US-compliant stablecoin (USAT) under the GENIUS Act.

Has any stablecoin issuer completed a full audit?

No major stablecoin issuer has completed a comprehensive, full-scope audit of the type applied to traditional financial institutions. Circle and Paxos publish monthly attestation reports from Big Four firms (Deloitte and KPMG respectively), which confirm that reserves exceed liabilities at a specific point in time. Tether publishes quarterly attestations from BDO. Attestations are narrower in scope than full audits: they verify specific assertions rather than examining the complete financial picture. The GENIUS Act now requires monthly attestations examined by PCAOB-registered firms for US issuers.

What happens to my stablecoins if the issuer goes bankrupt?

It depends on the issuer's regulatory structure. For NYDFS-regulated issuers like Paxos, customer reserves are held in trust and are segregated from the company's operating funds, providing priority claims in bankruptcy. The GENIUS Act also grants stablecoin holders priority in an issuer insolvency. For issuers in lighter-touch jurisdictions, holders may become unsecured creditors. For decentralized stablecoins like DAI, there is no issuer to go bankrupt, but smart contract exploits or liquidation cascades during market downturns pose equivalent risks.

Are decentralized stablecoin issuers safer than centralized ones?

Neither model is inherently safer. Decentralized issuers like Sky (DAI/USDS) offer on-chain transparency and censorship resistance but carry smart contract risk, governance risk, and oracle manipulation exposure. Centralized issuers like Circle and Paxos offer regulatory protections and direct dollar redemption but introduce counterparty risk and potential for asset freezes. Most risk-aware users diversify across both models rather than concentrating in one.

Which stablecoin issuer operates on Bitcoin?

Flashnet (via Brale) is currently the only stablecoin issuer with a token operating natively on the Bitcoin network. USDB is issued on Spark, a Bitcoin layer-2 protocol, and is compatible with the Lightning Network. Other major stablecoins like USDT and USDC are available on Ethereum, Solana, Tron, and other networks but do not operate natively on Bitcoin.

How does the GENIUS Act affect stablecoin issuers?

The GENIUS Act, signed into US law in July 2025, requires payment stablecoin issuers to maintain 1:1 reserves in high-quality liquid assets (cash, insured deposits, short-term Treasuries), publish monthly reserve attestations examined by PCAOB-registered accounting firms, and comply with AML/BSA requirements. Issuer CEOs and CFOs must personally certify attestation accuracy. The law also grants stablecoin holders priority claims in the event of issuer insolvency, providing consumer protections previously absent from the market.
