OpenNode

• Name: OpenNode
• URL: https://opennode.com/
• Category: Bitcoin payments / merchant processing / payout infrastructure
• Tags: bitcoin-ecosystem
• Summary: OpenNode is hosted Bitcoin processing: checkout, settlement, payouts, and optional fiat conversion. Useful operator software, not a deeper Lightning primitive.
• What it does:
  • Lets businesses accept bitcoin payments through APIs, ecommerce plugins, and hosted payment pages
  • Supports both on-chain Bitcoin and Lightning Network payment collection, with instant-settlement positioning on Lightning
  • Exposes API primitives for creating charges, receiving payment-status callbacks, redirecting users after payment, and configuring settlement behavior
  • Documents withdrawal and payout surfaces, including multiple withdrawal types such as Lightning, on-chain, wire, exchange, and internal transfer variants
  • Offers auto-settlement and fiat-conversion features in official materials for businesses that want Bitcoin acceptance without full BTC price exposure
• Key claims:
  • The official site describes OpenNode as “Bitcoin payments at the speed of now” and emphasizes low-cost Bitcoin payments and payouts for businesses
  • OpenNode claims businesses can protect themselves from BTC price volatility by automatically converting bitcoin to local currencies at the time of payment
  • The docs portal positions OpenNode as infrastructure for building Bitcoin payment systems rather than just using a hosted merchant page
  • The create-charge API reference shows a fairly complete merchant checkout surface including fiat-denominated charge creation, callback URLs, success redirects, auto-settlement, and split-to-BTC controls
  • The withdrawals API material indicates OpenNode’s product surface extends beyond inbound checkout into treasury and payout operations
• Whitepaper: No classic whitepaper or litepaper was found during this pass. The strongest primary materials were OpenNode’s official site, docs portal, charge-creation API reference, and withdrawals reference pages; see ../whitepapers/opennode-primary-sources-2026-04-25.md.

Internal linkages

• Best upward reads: btcpay-server and blink.

Control surface

• Practical authority sits in merchant onboarding, checkout creation, settlement rules, payout approval, and whether OpenNode converts flows back into fiat.

• Read it as a managed processor with treasury edges, not as a canonical Lightning infrastructure note.
