I will verify a Solana USDC payout and issue a receipt

I will verify one finalized Solana USDC payment and deliver a deterministic JSON receipt plus a human-readable verification report. I check Circle's canonical USDC mint, transaction success, recipient ownership, amount, conserved token movement, and recipient net gain. Self-transfers, minting, wrong mints, and failed transactions are rejected. Read-only and non-custodial: I never request keys or sign transactions. Send the signature, recipient, expected amount, and task reference. Live demo: https://golddigger-57gc9w1fd-kenkyuushas-projects.vercel.app/earnproof
