Stablecoin infrastructure providers in 2026: the institutional map

“Stablecoin infrastructure provider” is a label that covers at least four different products, and most provider comparisons fail by treating them as one. An institution shortlisting vendors in 2026 is really choosing between four models: issuer networks (Circle, Paxos), custody-first platforms (Fireblocks), payment API platforms (BVNK, Bridge, Zero Hash, Conduit), and rail-neutral settlement layers (Frame). This page maps the market by model, states what each provider is best for, and sets out the questions that separate them.

A note on interest: Frame builds one of the platforms on this list. Descriptions of every provider draw on their published material, linked in the sources.

The map in brief:

• Issuer networks mint the token and run a network anchored to it. Deep liquidity in their own coin, and a structural commitment to it.
• Custody-first platforms started by securing digital assets and grew payment networks on top.
• Payment API platforms abstract stablecoin plumbing behind APIs for payins, payouts, and wallets. Two of the largest have been acquired by card schemes and PSPs.
• Settlement layers orchestrate stablecoins as one rail among several, alongside fiat systems and tokenized deposits.

Issuer networks

Circle

Circle issues USDC and EURC, both authorized as e-money tokens under MiCA, and counts more than $28 trillion in cumulative USDC settlement since 2018. Its Circle Payments Network, live since May 2025, coordinates payments between vetted financial institutions that settle directly with each other in Circle’s coins; the company reported the network reaching $3.4 billion in annualized transaction volume in its 2026 report. CPN supports Ethereum, Solana, Polygon, and EVM-compatible chains.

The model: the network is the coin. Every CPN payment deepens USDC liquidity, which is precisely why it works and precisely what it commits you to.

Best for: institutions that want the deepest regulated dollar-stablecoin liquidity and are comfortable anchoring to one issuer’s tokens.

Paxos

Paxos is a regulated issuer that mints tokens for other institutions under New York trust supervision: PayPal USD for PayPal, and USDG, the token behind the Global Dollar Network it launched with partners including Anchorage Digital, Galaxy Digital, Kraken, Nuvei, and Robinhood. USDG is also issued for EEA availability under MiCA documentation.

The model: issuance as a service. The brand on the coin is yours or a partner’s; the reserve management and regulatory reporting are Paxos’s.

Best for: institutions that want their own branded token, or a share of network economics, without building an issuance stack.

Custody-first platforms

Fireblocks

Fireblocks began as institutional digital asset custody and wallet infrastructure and now operates a payments network on top of it. The company states its infrastructure has secured over $10 trillion in transaction volume, and launched the Fireblocks Network for Payments in September 2025 across more than 100 countries.

The model: security first. Custody, key management, and policy controls are the foundation; payments are a workflow built on them.

Best for: institutions whose primary requirement is holding digital assets safely at scale, with payments as an extension of custody rather than the other way round.

Payment API platforms

Bridge (a Stripe company)

Bridge provides stablecoin issuance and orchestration APIs and became Stripe’s stablecoin arm when the acquisition closed in February 2025, in a deal reported at $1.1 billion. It now powers Stripe’s stablecoin products, giving it distribution few standalone platforms can match.

The model: stablecoin plumbing behind a developer-grade API, increasingly woven into Stripe’s broader payments stack.

Best for: businesses already building on Stripe, and teams that want issuance and orchestration from one API with PSP-scale distribution behind it.

BVNK (Mastercard acquisition pending)

BVNK is a London-based stablecoin payments platform offering payins, payouts, and embedded wallet infrastructure across fiat and stablecoin rails, with coverage including money transmitter licensing across all 50 US states and an integration powering stablecoin payouts for Visa Direct. In March 2026 Mastercard agreed to acquire it for up to $1.8 billion; BVNK states the deal is subject to regulatory approvals it expects to conclude in late 2026. We look at what the acquisition means for buyers in BVNK alternatives after the Mastercard acquisition.

The model: a payments API across fiat and stablecoin rails, now aligning with a card scheme’s network strategy.

Best for: PSPs and platforms that want proven stablecoin payin/payout coverage and see scheme ownership as continuity rather than concern.

Zero Hash

Zero Hash provides embedded digital asset and stablecoin infrastructure for brokerages, fintechs, and platforms, handling the regulated plumbing behind the scenes. It raised a $104 million Series D-2 led by Interactive Brokers in September 2025, reaching a $1 billion valuation.

The model: B2B2C. Your customers see your product; Zero Hash operates the regulated stablecoin and digital asset layer underneath.

Best for: consumer-facing platforms embedding stablecoin functionality without holding the regulatory and operational burden themselves.

Conduit

Conduit is a cross-border payments platform that uses stablecoin rails to move business payments, focused on corridors where correspondent chains are slowest, including Latin America and Africa. It raised a $36 million Series A co-led by Dragonfly and Altos Ventures in 2025.

The model: stablecoins as an invisible middle leg: fiat in, stablecoin across, fiat out.

Best for: businesses moving money on emerging-market corridors where the correspondent banking alternative is measured in days.

Settlement layers

Frame

Frame is the settlement layer for global finance: one integration to orchestrate payments at scale across fiat rails, stablecoins, and tokenized deposits, with compliance enforced on every transaction and settlement in seconds instead of days. Frame does not issue a coin and is rail-neutral: it routes each payment across whichever rail fits the corridor, the counterparty, and the policy that governs it. Its Rules Engine evaluates every transaction against its governing policies inside settlement, and every settled transaction produces verifiable evidence that its conditions were met, without exposing the underlying business data.

The model: the layer above the rails. Stablecoins are one rail among several, which means the platform has no structural stake in which coin, network, or rail wins.

Best for: banks, payment providers, exchanges, platforms, and enterprises that want stablecoin capability without betting on a single coin or network, and that need compliance enforced in the settlement path itself.

How to choose

Four questions separate the models faster than any feature list:

1. Who issues the value you settle in? If the answer is “our provider”, you have depth in that coin and exposure to its regulatory position in every market you operate in. Only USDC and EURC among major dollar-linked and euro-linked tokens are MiCA-authorized; routing flexibility matters most where regimes diverge.
2. Who holds the assets? Custody-first platforms make this their core competence. Issuer and API models vary; ask specifically.
3. What happens to the roadmap after acquisition? Two of the largest independent platforms now answer to Stripe and, pending closing, Mastercard. That can mean more distribution and investment, and it can mean alignment with the owner’s network priorities. Ask how neutrality between schemes, PSPs, and coins is preserved.
4. Is the stablecoin the product, or one rail among several? If your flows will always be stablecoin-shaped, a specialist is efficient. If some corridors are better served by fiat systems or tokenized deposits, infrastructure anchored to one rail leaves you running parallel stacks, and your liquidity fragmenting across them.

Where Frame fits

Frame’s answer to this map is the fourth category: a settlement layer that treats stablecoins as one rail in a wider settlement fabric. A payment enters through one integration, and Frame routes it across a fiat network, a regulated stablecoin, or a tokenized deposit, whichever the corridor and the governing policy call for. Compliance runs inside settlement: the Rules Engine evaluates every transaction, and a transfer that cannot satisfy its policies does not settle.

The consolidation wave makes the distinction sharper. As issuers anchor networks to their coins and schemes acquire the API platforms, the infrastructure that remains neutral across all of them becomes the piece an institution can adopt without picking a winner. The full landscape of stablecoin settlement, including bank-issued tokens and consortium networks, is mapped in stablecoin settlement infrastructure for regulated institutions.
