Sphere

Sphere is a next-generation crypto payments infrastructure platform built on Solana, providing APIs and tools for businesses to accept and process cryptocurrency payments at scale. It targets enterprises and developers who need robust, programmable payment processing with compliance features. Sphere's API-first approach differentiates it from simpler payment tools — developers can integrate crypto payment acceptance into any application with comprehensive REST APIs that handle wallet creation, payment detection, refunds, and settlement. The platform supports multiple payment methods including on-chain SOL and SPL token transfers, with automatic conversion options for merchants who prefer settlement in stablecoins. The platform also offers checkout pages, invoicing, and subscription management for merchants who prefer no-code solutions. Sphere's compliance features include KYC/KYB integration capabilities and transaction monitoring, making it suitable for regulated businesses that need to accept crypto payments while maintaining compliance requirements. Sphere focuses on providing the infrastructure layer that other payment products can build upon, similar to how Stripe serves as the backend for thousands of different payment interfaces. The platform has attracted notable clients in the Solana ecosystem and continues to expand its feature set with cross-chain payment support and advanced reconciliation tools.
