Changelog

What we shipped.

A running record of changes across the velapay stack: the channel protocol, audited contracts, the SDKs, and the developer platform. Newest first. Anything that touches settlement math or trust thresholds ships only after it clears review.

Swarm escrow, generally available

Swarm escrow leaves preview. Coordinators can now fund a single escrow that pays out to many workers on milestone completion, with the thawing window enforced on-chain for every release.

  • Contracts: swarm escrow promoted to GA after the third-party audit closed with no open findings.
  • Protocol: per-worker thaw windows are now independent, so one disputed milestone no longer freezes the whole swarm.
  • SDK: @velapay/escrow 1.0.0 ships fundSwarm() and milestone webhooks.
  • Platform: escrow lifecycle is visible in the dashboard with a live thaw countdown per worker.

RAV redemption batching

Receivers can now batch multiple receipt-aggregate vouchers from the same payer into a single redemption, cutting settlement gas when several channels cross their trust threshold at once.

  • Protocol: RAV redemption accepts an array of vouchers and verifies them in one call.
  • Contracts: redemption entrypoint rewritten for constant-ish gas regardless of voucher count.
  • SDK: @velapay/sdk 0.9.0 auto-coalesces pending vouchers below the gas-economical threshold.

Stateless channel protocol v2

A revised one-way channel format that shrinks the signed receipt and makes tallying cheaper for high-frequency, sub-cent calls.

  • Protocol: receipts are 38% smaller; nonce handling moved fully off-chain.
  • SDK: signing and verification helpers updated; v1 receipts remain redeemable through a compatibility shim.
  • Platform: tally meters in the dashboard now stream live as receipts accumulate toward threshold.

Audit milestone & node hardening

The core channel and redemption contracts completed their second independent audit. Node operators get tighter defaults and clearer health signals.

  • Contracts: second audit closed; full report published to the security page.
  • Protocol: formal spec of the threshold-trust model is now versioned alongside the contracts.
  • Platform: node infrastructure ships rate-limit and replay-protection defaults out of the box.

Developer platform & dashboard beta

The first public cut of the velapay dashboard: see channels, receipts, and settlements in one place, with API keys you can scope per agent.

  • Platform: channel and settlement views, plus per-agent scoped API keys.
  • SDK: @velapay/sdk 0.8.0 with a one-line openChannel() and typed receipt streams.
  • Protocol: trust thresholds are now configurable per receiver and surfaced in the dashboard.
