Best stablecoin infrastructure for fintechs, exchanges, and financial institutions (2026)

Introduction

Stablecoins are the base layer for a new generation of financial products. Neobanks use them to offer dollar accounts in markets where correspondent banking is broken. Remittance apps settle cross-border in seconds. Payroll platforms, marketplace payout systems, and treasury tools clear payments 24/7, including weekends and bank holidays.

The teams building these products have a choice in how they build. They can extend a payment network that has added stablecoin capabilities, or they can build on infrastructure designed for stablecoins from day one. The first path inherits the network's roadmap, pricing, and priorities. The second lets teams own the payment flow end to end.

That choice shapes what teams can ship and how fast. Infrastructure built for stablecoins exposes accounts, rails, compliance, and mint/redeem as programmable primitives. Stablecoin modules bolted onto other products expose a narrower surface area, with the buying patterns of a different customer underneath.

Here are four stablecoin infrastructure platforms worth evaluating in 2026.

Quick comparison: 4 stablecoin infrastructure platforms

• HIFI is the software platform for building financial products on stablecoins. Named US dollar virtual accounts at Cross River Bank, direct access to every major US rail, and direct mint and redeem across five stablecoins.
• Zerohash is a crypto-as-a-service platform offering trading, custody, and stablecoin payments to fintechs and banks adding digital asset capabilities to their products.
• Stripe is extending its payments network into stablecoins via its acquisition of Bridge, letting Stripe merchants accept USDC and settle in fiat without a separate crypto integration.
• Mastercard is extending its card network into stablecoins via its acquisition of BVNK, letting processors, acquirers, and issuers add stablecoin settlement to existing card flows.

Each section below covers the product in detail and how it compares for infrastructure use cases.

1. HIFI: Best for developer and product teams building financial applications on stablecoins

HIFI is the software platform for building financial products on stablecoins. Developer and product teams at fintechs, exchanges, and financial institutions use HIFI's APIs to build treasury tools, remittance apps, payroll platforms, marketplace payout systems, and  neobanks — without having to become a payments company underneath.

Key features

• Named US dollar virtual accounts at Cross River Bank, with dedicated routing numbers across ACH, RTP, FedNow, FedWire, and SWIFT.
• International payouts via SWIFT and in-country rails, including PIX in Brazil, SPEI in Mexico, and FPS in Hong Kong.
• Direct mint and redeem of USDC, USDG, PYUSD, and RLUSD, 24/7, including weekends and bank holidays.
• Native support across Ethereum, Polygon, Base, all other EVM chains, Canton, Tron, Solana, Stellar, and Ripple.
• KYC in minutes, KYB in hours. HIFI handles document collection, verification, bank submission, transaction monitoring, OFAC sanctions screening, adverse media checks, and fraud network flags through a single API.
• $6 billion in annualized transaction volume across fiat and stablecoins.
• Trusted by fintechs and institutions such as Dapper Labs, Sumitomo, Nuvera, Paxos, Circle, MoonPay, Arival, and Ourbit.

Limitations

HIFI is infrastructure, not a consumer-facing product. Platforms that need a hosted checkout for their end users will integrate HIFI's APIs underneath their own interface, or pair HIFI with a merchant-focused partner.

Verdict

HIFI is the most complete option for developer and product teams that need programmatic access to US payment rails, multi-stablecoin mint and redeem, and fast compliance throughput. One integration covers accounts, compliance, and payments. Teams go live in under a week.

2. Zerohash: Best for fintechs adding digital asset capabilities across trading and custody

Zerohash is a crypto-as-a-service platform that lets fintechs, banks, and brokerages embed digital asset capabilities into their products. Its offering spans crypto trading, staking, custody, tokenization, and stablecoin payments, packaged under a single regulated umbrella.

Key features

• Digital asset trading across ~40 cryptocurrencies via a Central Limit Order Book and RFQ system, accessed through a FIX API for brokerage-grade execution.
• Qualified custody for partner-held digital assets, including proof-of-stake staking with lockup management.
• Crypto asset support enables payouts in Bitcoin, Ethereum, Solana and 30+ more assets.

Limitations

• Stablecoin payments are one module in a broader digital asset platform, not the focus of the product.
• Direct US rail connectivity is still being built out compared to providers with named bank accounts and full rail access.
• Breadth across trading, custody, tokenization, and payments means product depth in any one area is different from a specialist.

Verdict

Zerohash fits fintechs and banks building a crypto program that spans trading, custody, tokenization, and digital asset payments under one regulated umbrella. The buyer is a team adding crypto to an existing product, with stablecoin payments as one capability among several.

For teams whose product is stablecoin-native, where the stablecoin is the product, HIFI is purpose-built for the job.

3. Stripe (Bridge): Best for merchants adding stablecoin checkout

Stripe is extending its payments network into stablecoins via its acquisition of Bridge, letting Stripe merchants accept USDC and settle in fiat without adding a separate crypto integration. For businesses already on Stripe, the result is an integrated path from checkout to card issuance to stablecoin issuance, delivered inside one product suite.

Key features

• Support for USDC and Stripe’s own USDB.
• Open Issuance framework for launching a branded stablecoin.
• Works directly via Stripe Checkout, Payment Links, and the Stripe API without a separate crypto integration.

Limitations

• Stablecoin support is limited to USDC and Stripe's own USDB, with a roadmap that increasingly favors the issuer Stripe controls.
• Using Stripe ties stablecoin flows to Stripe's payment network, billing, and compliance stack. Platforms that want to own their payment stack independent of Stripe face a structural mismatch.
• No direct access to the fastest US domestic payment rails (RTP, FedNow) as programmable infrastructure separate from Stripe's payment flow.

Verdict

Stripe is the strongest option for businesses already running on Stripe who want stablecoin capabilities inside the same platform: accepting stablecoin at checkout, issuing cards against a stablecoin balance, or launching their own stablecoin via Open Issuance. The distribution is enormous and the integration path is direct.

For teams building stablecoin-native financial products on their own stack — where the stablecoin is the product, not a settlement option inside Stripe's ecosystem — the requirements are different. HIFI exposes US payment rails, multi-stablecoin mint and redeem across the largest stablecoins, and programmable workflows as independent primitives.

4. Mastercard (BVNK): Best for processors and acquirers adding stablecoin settlement to card flows

Mastercard is extending its card network into stablecoins via its acquisition of BVNK, with the transaction expected to close in late 2026 pending regulatory approval. The combined offering is designed to extend Mastercard's global card network with stablecoin settlement and onchain payout capabilities, built for the processors, acquirers, and issuers already inside the Mastercard ecosystem.

Key features

• Mastercard's brand credibility and global regulatory footprint.
• Stablecoin settlement and checkout designed to plug into Mastercard's existing card rails.
• Push-to-card, account, and wallet payout rails through Mastercard's global fiat infrastructure.

Limitations

• US rails are still maturing compared to European rails.
• The core buyer is the processor, acquirer, or merchant extending card flows, not the platform building stablecoin-native financial products.
• Mastercard (BVNK) stablecoin roadmap is increasingly oriented around Mastercard's card rails, while HIFI exposes accounts, rails, and mint/redeem as independent programmable primitives.

Verdict

Mastercard's stablecoin offering fits businesses already running on Mastercard's rails who want to add stablecoin settlement to their existing card flows. For processors, acquirers, and merchants inside that ecosystem, it's a convenient way to extend card capabilities into stablecoins without leaving the network.

For platforms building stablecoin-native products — where the stablecoin is the product, not a settlement layer underneath a card transaction — the requirements are different. HIFI exposes US payment rails, multi-stablecoin mint and redeem across five stablecoins, and programmable workflows as independent primitives. Platforms that need to own their payment flows end to end build on HIFI.

Buying guide: what platforms need from stablecoin infrastructure

The infrastructure you pick shapes how fast your team ships, how much of the payment stack you own, and how far your product can scale. For teams building stablecoin-native financial products, the capabilities below separate platforms built for stablecoins from payment networks that have extended into them.

Why platforms are building on stablecoin infrastructure

Stablecoin infrastructure solves problems that card networks and correspondent banking can't:

1. Dollar access in markets where banks won't open accounts. Stablecoins give platforms a way to offer USD accounts to customers in emerging markets, without needing a local entity or a US-based customer.

2. 24/7 dollar movement. Stablecoins settle in seconds, 24/7, including weekends and bank holidays. HIFI supports mint and redeem on the same schedule: always on.

3. Lower cost than correspondent banking. Correspondent banking adds fees at every hop: the sending bank, the intermediary, the beneficiary bank, plus FX markups. Stablecoin rails compress those hops into a single transaction.

4. One integration instead of many. Platforms traditionally stitch together a banking provider, a compliance vendor, an FX partner, and one or more stablecoin on/offramps. Infrastructure-grade providers consolidate these into a single API.

What to evaluate

1. API-first architecture built for platforms

Teams building financial products on stablecoins don't need a hosted checkout page. They need APIs that expose accounts, rails, compliance, and mint/redeem as programmable primitives they can compose into their own product.

What to look for:

• API-first architecture designed for platforms, not merchants.
• Programmatic access to accounts, rails, compliance, and stablecoin operations.
• Documentation and developer tooling built for engineering teams shipping into production.

HIFI advantage: One integration covers accounts, compliance, and payments, teams go live in under a week.

Why this matters: Platforms lose time and flexibility when they build around a product designed for a different buyer. Stablecoin capabilities bolted onto a card network or a crypto trading platform come with that platform's roadmap, economics, and priorities built in.

2. Direct access to US payment rails

For teams moving USD, direct access to US domestic payment rails is the single most important capability. Without it, platforms are forced to route payments through intermediaries that add cost, time, and counterparty risk.

What to look for:

• Named US dollar accounts with dedicated routing numbers.
• Coverage across every major US rail: ACH, RTP, FedNow, FedWire, and SWIFT.
• Accounts held at a US bank with FDIC insurance.
• Outbound payments that originate under the account holder's name, not a payment processor's.

HIFI advantage: HIFI provides named USD virtual accounts held at Cross River Bank, FDIC insured, with dedicated routing numbers across ACH, RTP, FedNow, FedWire, and SWIFT. Non-US platforms get the same rail access as a US bank customer, with outbound payments originating under their account holder's name.

Why this matters: Direct rail access means lower cost, faster settlement, and cleaner counterparty relationships. Platforms without it pay intermediary fees and wait longer for money to move.

3. Stablecoin capabilities: assets, chains, and mint/redeem

Stablecoin choice and chain coverage are two sides of the same question: where your customers' liquidity lives, and what it takes to meet them there. Teams that support only one stablecoin or a narrow set of chains force their customers onto a single issuer or a single network. As liquidity shifts, their product falls behind.

What to look for:

• Direct mint and redeem across multiple stablecoins, not just pay-in and conversion.
• 24/7 availability, including weekends and bank holidays.
• Native support across major L1s, L2s, and institutional networks: Ethereum, Solana, Polygon, Base, Tron, Canton, Stellar, Ripple.
• A roadmap that adds new chains and assets through the same API, with no re-integration required.

HIFI advantage: HIFI supports direct mint and redeem of USDC, USDG, PYUSD, and RLUSD. All four are available 24/7, including weekends and bank holidays, across every supported blockchain.

Why this matters: Platforms that offer only USDC force their customers into one stablecoin issuer and one liquidity pool. Multi-stablecoin support lets platforms meet developers where they are.

4. Compliance throughput at institutional speed

Compliance is the bottleneck in stablecoin infrastructure. Slow KYC and KYB frustrate customers and kill deals. Teams evaluating providers should benchmark compliance speed directly.

What to look for:

• KYC completion measured in minutes, not days.
• KYB completion measured in hours, not weeks.
• Automatic transaction monitoring, OFAC sanctions screening, adverse media checks, and fraud network flags built into the same API.
• Low request-for-information (RFI) rates on submitted applications.

HIFI advantage: KYC in minutes, KYB in hours. HIFI handles document collection, verification, bank submission, and ongoing monitoring through a single API, with the fastest onboarding in stablecoin infrastructure.

Why this matters: Every day of delay in onboarding is a day your customer can't transact. Platforms building stablecoin products need compliance that keeps up with product velocity.

5. Programmable workflows built on top of the primitives

Workflow tooling enables teams to build production financial products on top of the core primitives. Institutional treasurers need multi-party approvals. Payroll platforms need velocity limits. Finance teams need observability over every quote, every payment, and every settlement.

What to look for:

• Role-based access controls and multi-user permissions.
• Configurable transfer approvals with velocity thresholds and value-based sign-offs.
• Multi-party disbursement workflows.
• Observability into quote pricing, transaction status, and settlement timing.
• Reconciliation tooling, including CSV exports and automated payment receipts.
• UETR payment receipts for SWIFT and cross-border transactions.
• FX quote visibility and audit trails.

HIFI advantage: HIFI exposes a full stack of workflow tooling on top of its core banking and stablecoin primitives. Role-based access controls, configurable transfer approvals with velocity thresholds, multi-party disbursement flows, and observability are built into every transaction. UETR payment receipts, CSV reconciliation exports, and full visibility into FX quotes before execution come standard. One API covers primitives and workflows together.

Why this matters: Teams that build on bare-metal infrastructure end up building their own workflow layer: approvals, controls, observability, reconciliation. Teams that build on HIFI get the workflow layer as part of the platform.

The choice teams make

Stablecoin capabilities are available from a lot of places in 2026. Card networks have extended into stablecoin settlement. Crypto-as-a-service platforms have added stablecoin modules to their trading stacks. Payment networks have added stablecoin accounts, checkout, and issuance to their merchant stacks.

For teams building stablecoin-native financial products, where the stablecoin is the product and not a settlement layer underneath something else, the requirements are different. API-first architecture, direct access to US payment rails, multi-stablecoin mint and redeem across every major chain, fast compliance throughput, and programmable workflows built on top of the primitives sets teams up for building cutting-edge financial products.

HIFI is the software platform for the teams building those products.

FAQs

What is stablecoin infrastructure?

Stablecoin infrastructure is the set of APIs, accounts, compliance systems, and banking relationships that let platforms build financial products on stablecoins. A stablecoin-native platform like HIFI offers programmatic access to US payment rails, direct mint and redeem across multiple stablecoins, built-in compliance, and programmable workflow controls, all through one integration.

How is stablecoin infrastructure different from a payment gateway?

Payment gateways are built for merchants accepting payments from end customers, typically at checkout. Stablecoin infrastructure is built for platforms that need to embed stablecoin capabilities into their own products, with accounts, rails, and mint/redeem exposed as independent programmable primitives.

What rails should stablecoin infrastructure support?

For platforms moving USD, the critical rails are ACH, RTP, FedNow, FedWire, and SWIFT. Platforms should also evaluate international local payout rails like PIX (Brazil), SPEI (Mexico), and FPS (Hong Kong). HIFI covers all of the above.

Which stablecoins should infrastructure providers support?

At minimum: USDC, USDT, USDG, PYUSD, and RLUSD. HIFI supports all five.

How fast should KYC and KYB take?

For institutional use cases, KYC should complete in minutes and KYB in hours. Providers that measure KYB in days or weeks become the bottleneck in your product. HIFI is the fastest in stablecoin infrastructure, with KYC in minutes and KYB in hours.

Can non-US businesses access US payment rails through stablecoin infrastructure?

Yes. HIFI provides named US dollar virtual accounts at Cross River Bank to non-US businesses and individuals, with dedicated routing numbers across ACH, RTP, FedNow, FedWire, and SWIFT. Outbound payments originate under the account holder's name.

How long does it take to go live on stablecoin infrastructure?

It depends on the provider. Merchant gateways can take weeks or months for enterprise integrations. Infrastructure providers optimized for platforms can be faster. HIFI platforms go live in under a week, with one integration covering accounts, compliance, and payments.
