Voltage is Bitcoin and Lightning Network money infrastructure that lets financial platforms send and receive instant, permissionless payments at scale. Its Payments API (voltageapi.com/v1) exposes wallets, payments, quotes, and lines of credit for BTC and USD settlement, backed either by a Voltage-managed line of credit or your own Lightning node. Voltage also runs managed Lightning node infrastructure (LND, Core Lightning, BTCPay Server) with macaroon-based access, webhooks for real-time payment events, a Mutinynet staging sandbox, and built-in OFAC/compliance risk screening via Amboss Reflex. The platform is SOC 2 Type II and NMLS compliant.
