SpherePay is a B2B platform developed by Sphere Labs for international payments and settlements using stablecoins. The service combines on-ramp and off-ramp infrastructure, banking rails, multichain transfers, currency conversion, and compliance tools through APIs and a unified Dashboard. The model is primarily designed for fintech companies, payment providers, trading businesses, and other enterprises that need to move funds across borders without independently integrating multiple banking and blockchain providers. By 2026, SpherePay reports support for more than 160 markets, while the company's infrastructure is developing alongside SphereNet, a separate network designed for regulated institutional settlement.

1. What Is SpherePay and How Do B2B Stablecoin Payments Work?
Sphere Labs was founded in 2022 with a focus on infrastructure for moving digital dollars between traditional financial systems and blockchains. SpherePay is the company's payments platform. Its purpose is to provide businesses with a unified interface for international transfers, fiat-to-stablecoin and stablecoin-to-fiat conversion, and B2B settlements.
A key use case addresses the limitations of traditional cross-border payments. International transfers may pass through several correspondent banks, increasing settlement times and adding fees. Global companies may also need to maintain funds in local accounts in advance. Sphere uses stablecoins as an intermediate settlement layer that can move value more efficiently between different payment corridors.
For example, a company can deposit USD, convert the funds into a supported stablecoin through Sphere's infrastructure, and use blockchain rails for international settlement. On the recipient side, the asset can either be delivered directly to a crypto wallet or converted into local fiat currency and transferred through an available banking channel.
For the final recipient, such a payment does not necessarily appear to be a cryptocurrency transaction. Blockchain can operate only within the underlying settlement infrastructure while the sender and recipient continue using conventional bank accounts. SpherePay is therefore better understood as payment middleware connecting fiat rails with on-chain settlement rather than as a standalone consumer crypto wallet.
2. API, Dashboard, and International Payment Infrastructure
SpherePay's core product includes REST APIs and SDKs that allow companies to integrate payment infrastructure directly into their applications. The APIs cover payment instructions, on/off-ramp operations, bank accounts, transfers, and related functions. Businesses that do not require a custom integration can use the Dashboard to manage payments without writing code.
Another product is Embedded Ramp, which allows fintech applications, wallets, neobanks, and exchanges to integrate stablecoin purchases and sales directly into their interfaces. Sphere combines banking connectivity, conversion, compliance, and digital asset delivery, reducing the number of separate providers a client needs to integrate.
| Component | Type | Role in SpherePay |
|---|---|---|
| SpherePay API | Payment Infrastructure | Integrates international payments and on/off-ramp functionality into business applications |
| Dashboard | Business Interface | Allows companies to send, receive, and monitor payments without a custom integration |
| Embedded Ramp | White-Label Infrastructure | Adds stablecoin buying and selling functionality to third-party products |
| Private Desk | OTC Service | Supports large transfers, FX operations, and customized payment routing |
| Banking Rails | Fiat Infrastructure | Connect blockchain payments with local and international banking networks |
| Stablecoin Rails | Settlement Layer | Move digital value across countries and payment corridors |
SpherePay supports multiple methods for delivering funds. In 2026, the company added USD payouts through SWIFT, expanding access to approximately 11,000 financial institutions across more than 200 countries. SWIFT operates through the existing API, allowing businesses to make stablecoin-to-USD payments to recipients that do not use digital assets.
Sphere therefore does not attempt to replace the entire banking infrastructure with blockchain. Instead, the platform combines both layers and selects an appropriate route for each transaction. This is particularly relevant for B2B payments, where a supplier or contractor may require funds to arrive in a traditional bank account regardless of the technology used to move liquidity internationally.
3. USDC, USDT, Fiat On/Off-Ramps, and SpherePay Payment Economics
SpherePay primarily uses stablecoins as settlement instruments rather than investment assets. Supported assets include USDC and USDT. For certain products, Sphere supports USDC across Ethereum, Solana, Base, Polygon, Arbitrum, and Avalanche, while USDT is supported on Ethereum and Tron. Available networks and currencies depend on the specific payment product and region.
Multichain support allows Sphere to separate the user-facing payment experience from the underlying settlement layer. Clients do not necessarily need to select a blockchain for every transaction themselves, as the infrastructure can combine blockchain transfers, fiat conversion, and bank delivery within a single payment flow.
Key Elements of the SpherePay Payment Model:
- B2B payments and international settlements;
- USDC and USDT as major stablecoin rails;
- fiat-to-stablecoin and stablecoin-to-fiat conversion;
- APIs and SDKs for application integration;
- Dashboard for direct payment management;
- white-label on/off-ramp infrastructure for fintech services;
- local banking payment networks;
- SWIFT for international USD payouts;
- multichain support for digital assets;
- KYC, KYB, AML, and transaction monitoring.
One potential economic benefit of this architecture is reducing the need for prefunding. International companies may traditionally keep working capital across several bank accounts to cover future payments. Stablecoin settlement can allow funds to move closer to the actual time of settlement, potentially reducing the amount of idle liquidity held across different markets.
Stablecoins, however, do not eliminate all payment costs. The final cost of a B2B transfer depends on the currency corridor, on/off-ramp method, banking network, FX conversion, and requirements of the relevant jurisdiction. The benefits of blockchain settlement therefore need to be evaluated for each payment route rather than based solely on the cost of an on-chain transaction.
4. Solana, Multichain Infrastructure, and Compliance at Sphere Labs
Solana played a notable role in Sphere's early development. The project built payment tools around fast, low-cost blockchain transfers and received support from participants in the Solana ecosystem. SpherePay later evolved into a multichain product because global payment infrastructure needs to work with assets and liquidity distributed across multiple networks.
The payment infrastructure extends well beyond the blockchain layer. Sphere must connect digital assets with bank accounts, local payment systems, and identity verification procedures. KYB is particularly important for a B2B product, while consumer-facing on/off-ramp scenarios may additionally require KYC.
Sphere positions compliance as an integrated part of the payment process. Its infrastructure includes identity verification, AML screening, transaction monitoring, and other risk-management mechanisms. This distinguishes a corporate payment platform from a simple transaction between two self-custody wallets: using a public blockchain does not remove the legal obligations of financial intermediaries.
SphereNet is a separate infrastructure initiative from Sphere Labs. It should not be confused with SpherePay: SpherePay provides APIs and payment tools for international transactions, while SphereNet is being developed as a shared ledger for regulated institutional value transfer. The network uses the Solana Permissioned Environment and focuses on compliance, privacy, and interaction between financial institutions.
This distinction reflects Sphere Labs' broader strategy. The company is developing an application-level payment platform for businesses while simultaneously building infrastructure for institutional settlement. The practical value of this model will depend on how effectively its banking, blockchain, and compliance components can operate as an integrated system.
5. SpherePay Development and the Future of B2B Stablecoin Payments
In 2024, Sphere Labs raised $5 million in a strategic funding round involving Coinbase Ventures, Kraken Ventures, Anagram, Anza, Pyth Network, Temporal, and other investors. The funding supported the development of the company's payment infrastructure and broader market expansion.
By 2026, SpherePay reports coverage across more than 160 markets and provides infrastructure for fintech, global trade, treasury, marketplaces, and other B2B use cases, including traditional rails such as SWIFT. In July 2026, Sphere also joined the Mastercard Crypto Partner Program.
The main driver of future growth is practical business demand for stablecoin settlement. For companies, the value lies in faster international settlements, reduced prefunding requirements, more efficient working-capital management, and the ability to connect multiple payment corridors through a unified API.
Regulatory, banking, and infrastructure risks remain. These include stablecoin depegging, availability of local payment rails, compliance requirements, and blockchain-related disruptions. Fast on-chain settlement also does not guarantee that every fiat payout will be completed at the same speed.
SpherePay illustrates a model in which stablecoins function as an internal settlement layer for B2B payments while end users do not necessarily interact with cryptocurrency directly. Its long-term prospects will depend on real payment volumes, geographic coverage, the quality of its on/off-ramp infrastructure, and Sphere's ability to connect blockchain settlement with regulated banking systems.
