Hyperspace Chain v1.3.0

Tempo-inspired payment UX improvements + full end-to-end streaming channel wiring.

New Features

  • 32-byte memo field on streaming payments (experiment reconciliation)
  • Fee sponsorship (apps/coordinators cover agent channel costs)
  • hspace_payBatch (atomic batched payments in one RPC call)
  • P256/passkey auth (WebAuthn-compatible alongside Ed25519)
  • Stablecoin denomination (feeToken on channels)
  • Payment metrics (verification latency tracking)

Wiring

  • hspace_pay RPC → HPNOperator via adapter bridge
  • 80-byte signing buffer (channelID + nonce + amount + memo)
  • Backward compatible with v1.2.0 channels (zero memo)

Includes all prior fixes

  • v1.1.0: Stateless pruner, catch-up drain, commit timeout
  • v1.2.0: Stateless execution pipeline, PCT nanochain routing
