hive-receipt v1.0.0

Universal Spectral-signed payment receipts — x402 Base USDC

What This Server Does

hive-receipt issues ed25519-signed receipts for any on-chain payment. The Spectral public key is advertised in the agent card, enabling offline verification by any party. On-chain verification is attempted via public RPCs for Base, Ethereum, and Solana — best-effort, non-blocking.

Tools

Tool Description
sign_receipt Sign a payment receipt. Verifies tx on-chain (best-effort). Returns Spectral ed25519 envelope. x402 gated.
verify_receipt Verify a receipt by receipt_id. Re-verifies ed25519 signature offline.
list_my_receipts List receipts for a payer_did. Public read.

Council Provenance

Ad-hoc launch — commodity surface. Passes NEED + YIELD + CLEAN-MONEY gates:

  • NEED: Every Hive tool settlement needs a portable, verifiable receipt.
  • YIELD: $0.001 per receipt at scale; $0.10 for audit grade. Fee stacks with checkout volume.
  • CLEAN-MONEY: Pure USDC on Base mainnet. No derivatives, no energy futures, no external exchange layer.

Spectral Cryptography

  • Algorithm: ed25519
  • Keypair generated at deploy time; persisted via SPECTRAL_PRIVKEY_B64 / SPECTRAL_PUBKEY_B64 env vars
  • Public key advertised in /.well-known/agent.json — enables offline verification without server trust

On-Chain Verification Networks

  • Base 8453 via eth_getTransactionReceipt
  • Ethereum via public LlamaRPC
  • Solana via getTransaction on mainnet

Best-effort — if RPC unreachable, verification_status:"unverified" is set and receipt is still signed.

Brand

Color: #C08D23 (Pantone 1245 C — Hive gold)
