Payment evidence that teams can reproduce.

The problem

A successful signature does not prove which invoice was paid. Teams still need to verify finality, token identity, recipient ownership, exact integer amount, references, and balance movement before updating business state.

PayOps records those facts as one deterministic decision with replayable evidence. Missing or conflicting evidence becomes a reviewable exception rather than a guessed match.

Why Solana

Production payment verification must understand both legacy and versioned transactions, including address lookup tables and CPI token transfers. It must also resolve SPL token-account ownership, finalized commitment, and Solana Pay reference accounts without treating a signature as sufficient proof.

PayOps makes these Solana-specific checks inspectable and keeps the exact rule and parser versions with the resulting evidence.

Engineering commitments

• Versioned public contracts and deterministic conformance fixtures
• Apache-2.0 packages that can run outside the hosted product
• Explicit exceptions instead of guessed payment matches
• Public release, security, contribution, and roadmap evidence
