Batch settlement that
captures 90%+ of GMV

High-volume micropayments shouldn’t lose 30–40% to per-settlement fees. BatchRail makes batch-settlement practical — managed channels on Base, with a public test facilitator you can point at today.

The Problem

Exact settlement is eating the margin

x402 volume is real. Average transaction sizes of ~$0.023–$0.031 mean a $0.001 facilitator fee consumes 32–43% of GMV.

Why batch isn’t winning yet

  • Counterparty risk blocks adoption
  • Tooling friction and accounting overhead
  • No durable channel state out of the box
  • Background claim / settle / refund is operationally heavy

What BatchRail changes

  • Hosted batch facilitator endpoints (x402 v2 compatible)
  • Managed channel claim / settle loops
  • Open examples you can run locally on Base Sepolia
  • Path to production hosting for merchants and agents
The Solution

Batch-settlement as the default

Buyer deposits once into escrow, signs cumulative off-chain vouchers, seller claims in bulk. BatchRail runs the facilitator path so merchants keep more of every payment.
