Fees & limits overview

This section covers how OrcaRail charges for hosted usage, plus fees and minimums that appear in payment quotes and withdrawals.

Hosted platform pricing

Hosted OrcaRail (our cloud API, dashboard, and hosted pay) is priced at $0.10 per completed transaction, with your first 1,000 transactions free. We structure it this way so the product stays a transparent, accessible public good while we operate the infrastructure.

Self-hosted OrcaRail Open source soon — deploying the open-source stack on your own infrastructure — has no software fee from us. You still pay your own infrastructure and third-party costs (e.g. RPC, gas).

For the items below, “fees” means amounts included in the payer’s quote (support, commission, bridge) and chain-level minimums, not the hosted per-transaction platform price above.

What we cover

  • Fees — Support fee, commission fee (API key), and bridge fee; how they are computed and included in the total amount the payer sends.
  • Payment minimums — Per-network minimum transfer amounts, validation, and how they affect support/commission (fee floor and supportMinimumApplied / commissionMinimumApplied).
  • Withdrawal minimums — Auto-withdrawal threshold and when withdrawals are skipped.
