How Banks and Payment Networks Are Integrating Stablecoins into Existing Systems in 2026

TL;DR

Everstake observes that banks and payment networks integrate stablecoins through three operational models: tokenized deposits, reserve relationships with public stablecoin issuers, and card-network rails routed through stablecoin settlement.

• Tokenized deposits are bank liabilities issued on-chain. JPMorgan JPMD on Base and Canton, Citi Token Services, and the HSBC Tokenized Deposit Service (TDS) are the production examples.
• Public stablecoin integration runs across Ethereum, Solana, Avalanche, and Stellar. Visa settles USDC with Cross River Bank and Lead Bank on Solana after a $3.5B annualized pilot.
• Mastercard MTN supports USDC, EURC, PYUSD, USDG, FIUSD, and now SoFiUSD for settlement and B2B flows.
• The GENIUS Act, signed on July 18, 2025, sets the federal framework for US payment stablecoin issuers, with full effect by January 18, 2027 at the latest.
• Stablecoin market cap reached roughly $322B in May 2026, with monthly on-chain settlement volume rivaling card networks.

Why Banks Are Adopting Stablecoins

Banks adopt stablecoins because settlement on SWIFT and correspondent banking is slow, expensive, and closed on weekends. A cross-border wire typically takes 1 to 5 business days and costs $25 to $50 per leg, while a tokenized payment on a public chain settles in seconds for cents.

Four operational pressures push the move:

• 24/7 settlement: markets and corporate treasuries operate continuously, but SWIFT and ACH do not.
• FX cost compression: atomic on-chain FX removes nostro/vostro pre-funding.
• Programmability: payments can be conditioned on documents, deliveries, or oracle data.
• Client demand: digitally native firms, exchanges, and merchants increasingly request on-chain payouts.

Client demand here is the strongest signal.

“Visa is expanding stablecoin settlement because our banking partners are not only asking about it – they’re preparing to use it,” said Rubail Birwadker, Global Head of Growth Products and Strategic Partnerships, Visa.

Three Integration Models

Banks integrate stablecoins through three distinct architectures: tokenized deposits, public stablecoin reserve relationships, and payment-network rails. Each carries a different legal nature, ledger model, and risk profile.

Regulators, auditors, and counterparties have a different use case for each model.

Model	Legal nature	Ledger	Example	Primary use case
Tokenized deposit	Bank deposit liability	Permissioned or permissioned-on-public	JPMorgan JPMD, Citi Token Services, HSBC TDS	Intra-bank and interbank settlement
Public stablecoin reserve	Non-bank issuer liability, bank holds reserves	Public (e.g., Ethereum, Solana)	BNY Mellon reserves for Circle USDC	Open-network payments, treasury
Payment-network rail	Card network settles in stablecoin	Public chains (Solana, Ethereum)	Visa USDC, Mastercard MTN	Issuer/acquirer settlement

A single bank can occupy more than one row. JPMorgan issues a tokenized deposit on Base, while Cross River Bank participates in Visa’s USDC settlement on Solana.

Tokenized Deposits Explained

A tokenized deposit is a digital representation of a commercial bank deposit liability, issued on a distributed ledger by the bank that holds the underlying deposit. It differs from a stablecoin in three structural ways.

• Issuer: a chartered bank.
• Reserve composition: backed by the bank’s general deposit liabilities, not a segregated reserve pool of Treasuries and cash.
• Insurance treatment: the underlying deposit may be covered by FDIC insurance in the US or equivalent schemes elsewhere, subject to regulator interpretation.

The token itself is permissioned. Only KYC-verified clients of the issuing bank can hold or transfer it.

The technical model typically combines a permissioned ledger for the issuance and burn mechanics with optional deployment on a public chain. JPMorgan’s JPMD sits on Base, an Ethereum Layer 2, but transfers are restricted to whitelisted addresses.

Payments can be conditioned on delivery confirmation, oracle prices, or atomic-FX swaps, replacing manual escrow and reconciliation steps.

Bank Pilots and Production Deployments

Several global banks now operate live tokenized deposit platforms, with JPMorgan, Citi, and HSBC ahead in production scope. Every institution has adapted a different architectural technology.

• JPMorgan Kinexys runs the longest-standing platform. JPM Coin launched on the private Kinexys Digital Payments ledger in 2019, then expanded to Base in November 2025 under the ticker JPMD. On January 7, 2026, Kinexys announced phased integration with the Canton Network throughout 2026, alongside Digital Asset.
• Citi Token Services uses a private permissioned blockchain for tokenized internal liquidity transfers. On September 29, 2025, Citi announced integration of the platform with its 24/7 USD Clearing solution, which supports 250+ banks across 40+ markets and enables multibank cross-border instant payments for UK and US institutional clients.
• HSBC Tokenized Deposit Service (TDS) launched in Hong Kong in May 2025 with Ant International as the first client, supporting HKD, USD, and SGD. By September 2025, HSBC added cross-border features and extended TDS to the UK and Luxembourg, with US and UAE rollouts scheduled for H1 2026.
• Standard Chartered, BNY Mellon, Deutsche Bank, and DBS run smaller production or pilot deployments. DBS issues tokenized deposits in SGD for institutional clients, BNY Mellon holds reserves backing Circle’s USDC, and Deutsche Bank participates in the Partior interbank network.

Payment Network Integration

Visa and Mastercard integrate stablecoins at the settlement layer, not the checkout layer. The experience for the consumer card holder does not change. The issuers and acquirers settle obligations with the network in the background.

Visa launched USDC settlement in the US on December 16, 2025, with Cross River Bank and Lead Bank as the first live participants, settling over Solana. Visa’s stablecoin settlement program reached a $3.5B annualized run rate as of November 30, 2025, building on prior pilots across Latin America, Europe, Asia-Pacific, and CEMEA.

Visa is also a lead design partner for Circle’s Arc blockchain, a Layer 1 built for stablecoin payments, and plans to operate a validator node once Arc mainnet goes live.

Mastercard Multi-Token Network (MTN) supports a broader stablecoin set: USDC, EURC, PYUSD, USDG, and FIUSD. On March 3, 2026, Mastercard and SoFi Technologies announced that SoFiUSD would be supported within MTN for card-transaction settlement and cross-border B2B money movement.

PayPal PYUSD, Western Union corridor pilots, and Stripe’s stablecoin payouts round out the payment-network landscape, though they sit a step removed from card-rail settlement.

Cross-Border B2B and Remittance Corridors

Banks and fintechs are routing select corridors through stablecoins where SWIFT and money transfer operators are slowest and most expensive. The leading corridors are USD-MXN, USD-PHP, USD-NGN, and US-LATAM broadly.

The cost differential is the main driver:

Channel	Average cost (200 USD send)	Speed	Hours
SWIFT correspondent	$25 to $50	1 to 5 business days	Business hours
Western Union	$5 + 1% (varies by region)	Minutes to hours	Extended
Card network FX	3% to 5% of amount	1 to 2 days	Business hours
Stablecoin on Solana	<$0.01 in network fees	Seconds	24/7

Stablecoin corridors do carry off-ramp costs: the recipient still needs local currency, and the local exchange or fintech that converts the stablecoin charges a spread. Net cost could result between 0.5% and 2% in most live corridors, still well below legacy rails.

B2B is the bigger volume story. Corporate treasury teams use USDC and PYUSD for supplier payments in jurisdictions where USD correspondent access is restricted, and for intraday liquidity between subsidiaries.

Compliance and Regulatory Frame

Stablecoin integration is a subject to a dense compliance: FATF Travel Rule, sanctions screening, KYC/AML, the Bank Secrecy Act (BSA), OFAC, and jurisdiction-specific regimes for issuance and custody.

What regulates the operating environment:

• GENIUS Act (US) signed July 18, 2025. Establishes a federal framework for payment stablecoin issuance, 100% reserve backing in USD or short-term Treasuries, monthly reserve disclosures, and BSA application. Effective the earlier of January 18, 2027 or 120 days after final rulemakings. State-qualified issuers capped at $10B in issuance.
• MiCA (EU) Article 75 governs e-money tokens, with operational rules already in force for European banks integrating stablecoins. Specific legal review is required for each Member State implementation.
• Hong Kong Stablecoin Ordinance passed May 2025, with HKMA licensing required for HKD-backed issuers. First licenses anticipated in Q1 2026.
• Singapore MAS framework covers single-currency stablecoins under the Payment Services Act, with reserve and audit requirements.
• Travel Rule FATF Recommendation 16 requires originator and beneficiary data on transfers above the local threshold, typically $1,000 or EUR 1,000.

Bank legal teams should treat each jurisdiction independently. Cross-border stablecoin flows may trigger multiple regimes simultaneously, and legal review is required before any production deployment.

Technical Integration: APIs, Custody, and Validator Infrastructure

Banks plug into stablecoin networks through three technical layers: API integration with issuers, qualified custody for on-chain assets, and validator infrastructure on the underlying public chains. Each layer carries its own SLA and risk profile.

API integration uses issuer-provided endpoints for minting, burning, and transferring stablecoins, alongside on-chain RPC endpoints for transaction submission and confirmation. Circle, Paxos, and PayPal all expose institutional APIs with rate limits, webhook callbacks, and reporting hooks.

Custody is the most regulated layer. Options include:

1. Qualified custodian (e.g., BNY Mellon, State Street Digital, Anchorage Digital, Komainu).
2. Multi-party computation (MPC) custody (e.g., Fireblocks, Copper, Taurus, Utila).
3. Hardware security module (HSM) self-custody, sometimes combined with MPC.

Bank treasury teams typically combine a primary Multi-party computation (MPC) custody (e.g., Fireblocks, Copper, Taurus, Utila).

Validator infrastructure matters whenever the bank settles on a public PoS chain. The chain’s validator set is part of the bank’s operational dependency: if validators go offline, transactions delay; if validators get slashed for misbehavior, delegated funds can take a haircut.

Bank infrastructure teams should evaluate validator operators on uptime, slashing history, geographic distribution, and integration coverage. Everstake publishes operational metrics and supports custodian-led deployments through partnerships with Taurus, Colossus Digital, Utila, and Paribu. See staking infrastructure for custodians and banks for the operational detail.

Where Validators Fit in Bank Stablecoin Operations

When a bank uses a public PoS chain to settle stablecoin transactions, the chain’s validator set becomes part of the bank’s payment infrastructure. Visa’s USDC settlement runs on Solana, where roughly 1,300 validators produce blocks; JPMorgan JPMD transfers on Base rely on Ethereum’s ~900K validators for L1 finality.

This creates an operational dependency the bank must monitor:

• Uptime: sustained validator downtime delays transaction inclusion.
• Slashing: validator misbehavior on chains like Ethereum, Polygon, or Avalanche can penalize delegated stake.
• Geographic distribution: concentration in a single jurisdiction is a regulatory and resilience risk.

For banks running their own nodes or delegating to operators, the operator’s track record matters as much as the chain’s. Everstake runs validators on Ethereum, Solana, Polygon, Cosmos, and 30+ other networks, with custodian-integrated workflows documented in the Paribu Custody x Everstake Case Study. 

Custodian-integrated staking is the model most banks adopt: the bank holds assets with a qualified custodian, the custodian routes delegation to vetted operators, and the bank gets a single reporting interface.

See institutional staking for the technical and operational scope.

Risks and Open Questions

Stablecoin integration carries the risk categories that bank risk teams may consider. Each is unresolved as of May 2026.

Reserve transparency 

Non-bank issuers publish monthly attestations, not full audits. Composition can shift between Treasuries, repos, and cash equivalents.

Run risk

The Silicon Valley Bank episode in March 2023 depegged USDC to $0.87 for 48 hours. Bank exposure to non-bank stablecoin reserves carries correlated tail risk.

Smart contract risk

Stablecoin contracts have been exploited; freeze and seize functions exist in USDC, USDT, and PYUSD but introduce centralization risk.

Interoperability 

Bank permissioned ledgers (Kinexys, Partior, Canton) do not yet interoperate cleanly with public chains. Cross-ledger settlement still requires bridges or atomic-swap protocols.

Outlook 2026 to 2027

Three trends will dominate bank stablecoin integration through 2027: Bank-issued deposit tokens and public stablecoins now run on the same chains, scaling from intra-bank to interbank flows, and the rise of agentic payments.

JPMorgan’s JPMD is a tokenized deposit issued on a public chain, blurring the line with USDC. Mastercard MTN supports both SoFiUSD (bank-issued) and USDC (non-bank) in the same settlement layer.

Interbank scaling depends on shared ledgers. Partior (backed by JPMorgan, DBS, and Standard Chartered), Canton, and Fnality are the leading interbank candidates. DTCC’s December 2025 decision to test tokenized US Treasuries on Canton is a notable institutional vote.

Agentic payments and autonomous software agents that hold and spend stablecoins on behalf of users or businesses  are an emerging category. They demand programmable, 24/7, low-fee rails. Stablecoin and tokenized-deposit infrastructure is the natural substrate.

Cross-CBDC interoperability is the longer arc. Projects like mBridge (multi-CBDC settlement) and the HKMA EnsembleTX pilot, launched in November 2025 with 7 banks including HSBC Hong Kong and Bank of China (Hong Kong), signal where public-sector and bank-sector rails may eventually meet.

FAQ

What is the difference between a tokenized deposit and a stablecoin?

A tokenized deposit is a digital representation of a commercial bank deposit liability, issued by a chartered bank. A stablecoin is issued by a non-bank entity (or, under the GENIUS Act, a permitted issuer), backed by a segregated reserve pool of cash and Treasuries. The issuer, reserve structure, and insurance treatment differ.

Which banks are issuing stablecoins or tokenized deposits?

As of May 2026, the production set includes:

• JPMorgan JPMD on Base and Canton
• Citi’s Citi Token Services on a private permissioned chain
• HSBC Tokenized Deposit Service (TDS) in Hong Kong, Singapore, UK, Luxembourg
• DBS tokenized SGD deposits
• Standard Chartered Partior participation
• Deutsche Bank Partior participation

Additional regional banks operate pilots under HKMA EnsembleTX, Singapore MAS Project Guardian, and ECB trials.

How does Visa use stablecoins?

Visa typically uses stablecoins (USDC) as a settlement asset between Visa and its issuer/acquirer partners, not as a consumer payment method. The cardholder experience is unchanged. 

Can a bank issue its own stablecoin under the GENIUS Act?

Yes, through a subsidiary but only through an approved structure and under regulatory supervision. Under Section 5 of the GENIUS Act, an insured depository institution can issue payment stablecoins through a subsidiary after applying to its primary federal payment stablecoin regulator. 

What is JPMorgan Kinexys?

Kinexys is the JPMorgan business unit (rebranded from Onyx in November 2024) responsible for blockchain-based digital payments and tokenization. Its products include Kinexys Digital Payments (Blockchain Deposit Accounts), JPM Coin (JPMD) as a deposit token on Base and Canton, and Kinexys Fund Flow for tokenized fund administration, scheduled for wider launch in 2026.

What stablecoins does Mastercard support?

Mastercard MTN supports USDC, EURC, PYUSD, USDG, FIUSD, and, following the March 3, 2026 announcement, SoFiUSD. The set covers both bank-issued and non-bank-issued tokens.

How large is the stablecoin market in 2026?

Total stablecoin market capitalization reached approximately $322B in May 2026, with USDT at roughly $189B and USDC at roughly $77B. Monthly on-chain stablecoin transfer volume now rivals Visa’s transaction value in several reporting windows.
