Stablecoin Infrastructure Providers

Circle issues USDC, backed 1:1 by cash and short-dated US Treasuries held at regulated financial institutions. USDC is natively available on 15+ blockchains (Ethereum, Solana, Avalanche, Base, Polygon, Arbitrum, and others). Circle provides: Circle Mint (direct mint/redeem for institutions), Circle APIs (programmable USDC transfers, accounts, payouts), Cross-Chain Transfer Protocol (CCTP, native cross-chain USDC transfers without bridging), and compliance tools. USDC has $30B+ in circulation and is the preferred stablecoin for institutional and regulated use cases. Circle holds money transmitter licenses in 49 US states plus international licenses.

Tether issues USDT with $110B+ in circulation, making it the largest stablecoin and one of the largest dollar-denominated instruments globally. USDT is available on every major blockchain and is the primary trading pair on virtually every centralized and decentralized exchange. Tether's reserves include US Treasuries, cash equivalents, and other investments. While USDT has faced scrutiny over reserve transparency (quarterly attestations rather than monthly audits), its dominance in trading volume and liquidity is unmatched. For emerging markets, USDT on Tron is the dominant dollar access channel. Tether also issues EURT (euro), CNHT (yuan), and XAUT (gold-backed).

PYUSD is issued by Paxos Trust Company (a New York-regulated trust) on behalf of PayPal. Available on Ethereum and Solana, PYUSD is backed 1:1 by USD deposits, short-term Treasuries, and cash equivalents with monthly attestations. PayPal's advantage is distribution: 400M+ PayPal and Venmo users can buy, hold, and send PYUSD within apps they already use. For merchants, PYUSD offers stablecoin settlement through existing PayPal merchant infrastructure. PYUSD represents the first major consumer fintech stablecoin and signals mainstream adoption of stablecoin payments.

Paxos is a New York Department of Financial Services (NYDFS) regulated trust company that provides stablecoin issuance infrastructure. Paxos issues: PYUSD (for PayPal), USDP (Pax Dollar, their own stablecoin), and PAXG (gold-backed token). Their Stablecoin-as-a-Service platform enables enterprises to issue their own branded, fully regulated stablecoins without building the compliance, banking, and technology infrastructure from scratch. Paxos handles: reserve management, regulatory compliance, mint/redeem operations, blockchain deployment, and attestation reporting. For banks and fintechs exploring stablecoin issuance, Paxos provides the turnkey regulated infrastructure.

First Digital Labs issues FDUSD, a USD stablecoin backed by cash and cash equivalents held in segregated accounts with a licensed Hong Kong trust company. FDUSD gained rapid adoption through Binance's zero-fee trading promotion for FDUSD pairs, making it one of the most traded stablecoins by volume. Available on Ethereum and BNB Chain, FDUSD serves as a key dollar asset in the Asian crypto ecosystem. For exchanges and platforms targeting Asia-Pacific users, FDUSD provides a regulated alternative with demonstrated exchange adoption.

Agora issues AUSD, a USD stablecoin designed specifically for institutional adoption. Backed by marquee investors including DragonFly Capital, Galaxy Digital, and others, Agora differentiates through institutional-grade infrastructure: custody partnerships with major financial institutions, professional reserve management, institutional onboarding processes, and compliance-first design. AUSD targets the gap between crypto-native stablecoins (which institutions find insufficient) and bank-issued stablecoins (which lack DeFi composability). For institutional treasuries, funds, and platforms, Agora provides a stablecoin built to meet their compliance and operational requirements.

MakerDAO (rebranding to Sky, with DAI transitioning to USDS) issues DAI, backed by overcollateralized deposits of ETH, wBTC, USDC, and increasingly real-world assets (US Treasuries via partnerships with Monetalis, BlockTower, and others). Users open Maker Vaults, deposit collateral, and mint DAI. The protocol is governed entirely by MKR holders who set risk parameters. DAI cannot be frozen or blacklisted (unlike centralized stablecoins), making it the preferred dollar asset for privacy-conscious users and censorship-resistant applications. MakerDAO generates $100M+ in annual revenue from stability fees and is one of the most profitable DeFi protocols.

Ethena issues USDe, a synthetic dollar backed by: long staked ETH positions (earning staking yield) hedged with short ETH perpetual futures (collecting funding rates when positive). This delta-neutral strategy historically produces 15-30%+ APY, far exceeding yields on USDC or DAI. sUSDe (staked USDe) accrues this yield automatically. Ethena has grown to $3B+ in supply, making USDe one of the fastest-growing dollar assets in crypto. The protocol also introduced ENA governance token and various incentive programs. Risks include: negative funding rates reducing yields, CEX counterparty risk for short positions, and potential de-peg during extreme market conditions.

Frax Finance has evolved from a fractional-algorithmic stablecoin to a full DeFi ecosystem: FRAX (stablecoin, now fully collateralized), sFRAX (staked FRAX earning yield from RWA and DeFi strategies), frxETH/sfrxETH (liquid staking with competitive yields), Fraxlend (lending protocol), Fraxswap (TWAMM-based AMM), and FPI (inflation-pegged stablecoin). Frax V3 moved to full collateralization with RWA backing (US Treasuries) and introduced Fraxchain (their own L2). For DeFi builders wanting to integrate with a comprehensive stablecoin ecosystem rather than just a single token, Frax provides the most vertically integrated solution.

Liquity V1 issues LUSD, backed by ETH collateral with immutable smart contracts (no admin keys, no governance, no upgrades possible). Users deposit ETH, borrow LUSD with a one-time fee (no ongoing interest), and can redeem LUSD for ETH at face value. This creates a hard price floor. Liquity V2 introduces BOLD, a next-generation decentralized stablecoin with user-set interest rates and multi-collateral support (ETH, LSTs). Liquity's immutability is unique: even the team cannot modify the protocol after deployment. For maximally decentralized applications and users who distrust governance (which can change rules), Liquity provides the hardest guarantee of non-interference.

Usual issues USD0, backed by tokenized short-term US Treasuries and other RWA. The protocol's innovation is redistribution: instead of the issuer keeping all reserve yield (as Circle and Tether do), Usual distributes yield and protocol ownership to users through the USUAL governance token. USD0++ (bonded USD0) provides enhanced yield for users willing to lock tokens. The model addresses a key criticism of major stablecoins: issuers earn billions from reserve yields while holders earn nothing. Usual has attracted significant TVL and positions itself as the 'fair' stablecoin alternative. For yield-seeking stablecoin users, Usual provides reserve-yield redistribution.

Bridge (acquired by Stripe for $1.1B) provides stablecoin orchestration APIs: convert fiat to stablecoins and back, move stablecoins across blockchains, handle KYC/AML compliance, and manage treasury operations. Bridge abstracts the complexity of multi-chain stablecoin operations behind a simple API. With Stripe's backing, Bridge is positioned to become the default stablecoin infrastructure for Stripe's millions of merchants and platforms. The acquisition signals Stripe's bet that stablecoins will become a major payment rail. For fintechs building on stablecoins, Bridge/Stripe provides the most well-funded and broadly distributed orchestration layer.

BVNK provides stablecoin payment infrastructure for businesses: accept stablecoin payments from customers, hold multi-currency balances (stablecoins + fiat), pay out suppliers and employees in stablecoins or fiat, and manage treasury across currencies. The platform handles: real-time conversion between stablecoins and fiat, compliance (KYB, transaction monitoring), multi-chain support, and banking integrations. BVNK serves businesses doing cross-border commerce where traditional banking is slow and expensive. For companies wanting to use stablecoins as their payment and treasury backbone (rather than traditional correspondent banking), BVNK provides the full-stack business payment platform.

Monerium is a licensed Electronic Money Institution (EMI) in the EEA, issuing EURe (euro stablecoin) that qualifies as electronic money under EU regulation. This means: holders have legal redemption rights (unlike most stablecoins), funds are protected under e-money regulations, and the token can be used for regulated payment services. Monerium provides IBAN accounts linked to on-chain addresses, enabling seamless fiat-to-stablecoin flows. For MiCA compliance, Monerium's e-money license positions EURe as one of the most compliant stablecoins in Europe. For EU businesses building on stablecoins, Monerium's regulatory status provides legal certainty.

Stasis issues EURS, a euro-backed stablecoin with 1:1 reserve backing verified through independent attestations. EURS is available on Ethereum and other chains and is listed on multiple exchanges for EUR trading pairs. For European DeFi participants and businesses that operate in euros, EURS provides on-chain euro exposure without currency conversion through USD stablecoins. As MiCA regulation takes effect, compliant euro stablecoins become increasingly important for EU-based operations. EURS serves the segment of the market that needs native euro denomination rather than converting through USDC or USDT.

Mountain Protocol issues USDM, a regulated yield-bearing stablecoin backed by short-dated US Treasuries. Unlike traditional stablecoins where the issuer keeps reserve yield, USDM passes Treasury yield through to holders by rebasing (the token balance grows daily). Mountain Protocol is regulated in Bermuda with reserves managed by qualified custodians. For DeFi protocols, USDM provides a yield-bearing dollar asset that can be used as collateral, in liquidity pools, or held in treasury, all while earning T-bill yields. For institutions, it offers a compliant way to earn on-chain yield backed by the safest collateral.

Ondo Finance issues USDY (US Dollar Yield), a tokenized note offering yield from US Treasuries and bank demand deposits. USDY is structured as a bankruptcy-remote, tokenized note (not a stablecoin per se) with daily yield accrual. Ondo requires KYC for holders, providing regulatory clarity and institutional acceptance. USDY is available on Ethereum, Solana, Mantle, and other chains. Ondo also offers OUSG (tokenized short-term Treasuries) for larger institutional allocations. For institutional DeFi participants who need compliant, yield-bearing dollar exposure (rather than zero-yield stablecoins like USDC), Ondo provides the bridge between Treasury markets and on-chain liquidity.

Maple Finance operates institutional lending pools where stablecoin deposits are lent to vetted, KYC-verified institutional borrowers. Pool delegates (professional credit managers) underwrite borrowers and manage pool risk. For lenders: deposit USDC or other stablecoins, earn yields higher than DeFi lending protocols through credit premium (undercollateralized lending to institutions). For borrowers: access working capital without overcollateralization requirements. Maple has facilitated $2B+ in loans and provides: Syrup (retail stablecoin yield product), institutional pools, and compliance infrastructure. For stablecoin treasury managers wanting higher yields with institutional credit exposure, Maple provides the managed lending marketplace.

Spark Protocol is the official DeFi lending and savings frontend for MakerDAO (Sky). Spark provides: DAI Savings Rate (DSR) deposits (earn yield on DAI set by MakerDAO governance), lending (borrow DAI against ETH, wstETH, and other collateral), and soon direct access to SubDAOs and new Sky ecosystem products. The DSR has been one of the most attractive risk-adjusted yields in DeFi, set by governance based on MakerDAO's revenue from stability fees and RWA yields. For users wanting simple, governance-backed stablecoin savings without active DeFi management, Spark's sDAI provides passive yield with MakerDAO's battle-tested infrastructure.

Coinbase operates Base (Ethereum L2 with low fees and high throughput), co-issues USDC with Circle (sharing revenue), and is developing cbBTC and stablecoin-native infrastructure. Base has become one of the most active L2s for stablecoin transactions, with native USDC support and Coinbase onramp integration. For developers, Base provides: low transaction costs for stablecoin transfers, Coinbase Smart Wallet (gasless onboarding), direct Coinbase user acquisition funnel, and compliance-friendly infrastructure. Coinbase's 100M+ verified users represent the largest fiat onramp to stablecoin services.

Visa has integrated USDC settlement on Ethereum and Solana into its global payment network. This means: acquiring banks can receive USDC settlement from Visa (instead of waiting for traditional bank wires), issuers can fund card programs with USDC, and cross-border settlement can bypass correspondent banking delays. Visa processes $14T+ annually and their stablecoin integration signals mainstream payment network adoption. For fintechs and neobanks building on stablecoins, Visa settlement compatibility provides instant credibility and access to the global merchant network. Visa has also published research on stablecoin analytics and Account Abstraction for payment use cases.

Mastercard enables crypto and stablecoin spending through its global card network. Their Crypto Credential program provides verified identity for on-chain transactions, while their card programs allow fintechs to issue Mastercard-branded cards that spend USDC, USDT, or other stablecoins with real-time conversion to local fiat at 100M+ merchant locations. Mastercard's Multi-Token Network (MTN) enables regulated stablecoin transfers between financial institutions. For stablecoin platforms wanting to give users spending power in the real world, Mastercard's card infrastructure provides the bridge between on-chain balances and everyday purchases.

Chainalysis provides compliance infrastructure critical for stablecoin operations: KYT (Know Your Transaction) screens real-time stablecoin transfers against sanctions lists, Reactor traces stablecoin flows across chains and mixers, and Business Data provides intelligence on stablecoin entities. For stablecoin issuers (who must maintain blacklists and freeze capabilities), Chainalysis identifies addresses associated with illicit activity. For exchanges listing stablecoins, Chainalysis provides the transaction monitoring required by regulators. The platform covers all major stablecoins across all major blockchains and is used by 1000+ organizations including government agencies.

TRM Labs provides risk management and compliance tools used by stablecoin issuers, exchanges, and financial institutions. Their platform covers: real-time transaction screening (check addresses and transactions against sanctions, darknet, ransomware, and other risk categories), cross-chain tracing (follow stablecoins across bridge transactions and chain hops), and risk scoring (programmatic risk assessment for every stablecoin transaction). TRM's coverage includes specific stablecoin analytics: freeze/blacklist monitoring, issuer compliance events, and stablecoin-specific risk indicators. Used by leading crypto exchanges and financial institutions, TRM provides the compliance layer that enables regulated stablecoin operations.

Elliptic provides compliance solutions for stablecoin operations: transaction screening, wallet screening, investigations, and regulatory reporting. Elliptic's differentiation is breadth of coverage, supporting 100+ blockchains including newer chains where stablecoins are being deployed. Their Holistic Screening product can trace assets across chains, including when stablecoins are bridged between networks. For stablecoin issuers and platforms operating across many chains, Elliptic's coverage ensures compliance even on newer or less-supported networks. Elliptic also provides stablecoin-specific analytics including reserve monitoring, cross-chain flow analysis, and blacklist tracking.

Notabene enables VASPs, exchanges, and stablecoin issuers to comply with FATF Travel Rule requirements: share originator and beneficiary information for crypto transfers above regulatory thresholds. Notabene connects 200+ VASPs in a compliance network, enabling stablecoin transfers between institutions with proper information sharing. As regulators globally enforce Travel Rule compliance, stablecoin transfers between exchanges and custodians require this infrastructure. Notabene handles: counterparty discovery (find and verify the receiving VASP), secure data exchange, compliance workflow automation, and jurisdictional rule management (different thresholds per country).

Perena's Numeraire is a stablecoin swap and liquidity protocol designed specifically for stablecoin-to-stablecoin trades. As the number of stablecoins grows (USDC, USDT, DAI, PYUSD, FDUSD, USDe, FRAX, USDM, and dozens more), the fragmentation problem intensifies: liquidity is split across many pairs. Numeraire addresses this by providing concentrated stablecoin liquidity and optimized swap algorithms specifically for pegged assets. For platforms that need to accept multiple stablecoins and convert between them (payment processors, exchanges, DeFi protocols), Numeraire provides the efficient conversion layer.

Conduit provides Rollup-as-a-Service infrastructure for deploying production Ethereum L2 chains. Several stablecoin-focused and payment-focused chains are built on Conduit's infrastructure. For stablecoin issuers considering their own chain (like Circle exploring dedicated USDC infrastructure), Conduit provides: deployment and management of OP Stack, Arbitrum Orbit, or other rollup frameworks, custom gas token configuration (pay gas in USDC instead of ETH), high throughput optimized for payment transaction patterns, and managed infrastructure (sequencing, data availability, bridge operations). As stablecoins scale to payment volumes requiring dedicated throughput, rollup infrastructure becomes critical.

M^0 (M Zero) is a decentralized protocol that enables qualified participants to mint M (a stablecoin) against high-quality collateral. Unlike centralized stablecoins (where one company controls issuance), M^0 creates an open framework: multiple approved minters can issue M tokens, collateral is verified through a decentralized validator network, and governance is handled by token holders. This creates a more resilient stablecoin system: not dependent on a single issuer, multiple collateral custodians, and transparent on-chain verification. For institutions that want to participate in stablecoin issuance without building their own infrastructure, M^0 provides the protocol layer.
