Stablecoin Fiat On/Off-Ramp Infrastructure

SpherePay provides a comprehensive suite of fiat on/off-ramp products that enable businesses to convert between fiat currencies and stablecoins across global payment rails — with options ranging from developer APIs to white-label embeds and high-touch OTC execution.

Developer Toolkit (Payments API)

The SpherePay REST API delivers a single integration point for the full cross-border payment lifecycle. Developers can programmatically accept fiat and convert to stablecoins, or convert stablecoins back to fiat via ACH (US), SEPA (Europe), Pix (Brazil), and wire transfers. Supported assets include USDC and USDT across Solana, Ethereum, Tron, and Base networks. Full compliance — KYC, KYB, and sanctions screening — is embedded at the API level, removing the need for separate compliance integrations.

Embedded Ramp (White-Label Widget)

The Embedded Ramp is a CDN-hosted JavaScript widget that integrates with approximately 20 lines of code, allowing any platform to offer fiat-to-stablecoin and stablecoin-to-fiat conversion directly within their product experience. SpherePay handles all underlying compliance, banking, and blockchain infrastructure. The widget supports custom theming, built-in KYC/KYB, and local payment rails including ACH, SEPA, Pix, and wire.

Business Dashboard (No-Code Operations)

The Business Dashboard is a self-serve web portal for finance and operations teams to execute on/off-ramp conversions, configure FX and routing rules, manage payout wallets, and monitor transaction status — all without engineering resources.

Private Desk (OTC High-Touch Service)

For large-scale or time-sensitive transfers, SpherePay's Private Desk provides concierge-level OTC execution with no volume limits. Services include dedicated FX quotes, crypto-to-crypto and fiat-to-fiat conversions, bespoke payment routing, and personalized support via Telegram, Slack, and WhatsApp.
