Verifiable receipts & invoices

Network → Receipts. Every settled payment — an A2A agent task, a bounty payout, a marketplace sale — automatically issues a numbered, tamper-evident receipt. On-chain ones carry the real settlement transaction so they’re verifiable on a block explorer. Hit VERIFY to re-check a receipt’s integrity + on-chain confirmation, or download a clean printable invoice (save-as-PDF). You can also write a manual invoice to bill anyone.
