What Voltage does
Voltage is a private Bitcoin Lightning Network infrastructure company founded in 2020, headquartered in Austin, Texas, operating with 11–50 employees. It provides enterprise-grade managed Lightning nodes, payment processing APIs, and a recently launched revolving line of credit (Voltage Credit) for businesses transacting on Bitcoin's Layer 2. The platform is built on LND (Lightning Network Daemon) and abstracts operational complexity — uptime, liquidity, key security, channel management — into a self-serve API and white-glove enterprise offering. Customers include cryptocurrency exchanges, iGaming operators, neo-banks, digital wallets, and payment service providers; named enterprise customers and integration partners include BitGo, Kraken, Secure Digital Markets, ALT5, UnoCoin, Unbank, Amber, YellowCard, and Braiins. BitGo's Lightning integration is powered by Voltage, and Voltage partnered with Amboss to combine its payments API with Amboss Rails for institutional yield and liquidity automation.
The core product portfolio spans Voltage Lightning Infrastructure (managed nodes), Voltage Payments (global settlement platform), and Voltage Credit (revolving line of credit with USD settlement, NMLS-licensed in 46 states). All nodes automatically run the Taproot Assets daemon, enabling asset issuance and stablecoin transfer over Lightning. Revenue mechanics include tiered subscription plans (Essentials free tier through custom Enterprise contracts), API access fees, and credit-based payment economics; go-to-market combines a self-serve developer platform (app.voltage.cloud) with enterprise field sales and strategy sessions. Compliance posture is anchored by SOC 2 Type II certification and NMLS lending licensure, and the company maintains channel partnerships with 20+ Lightning nodes covering approximately 95% of network capacity, which underpins routing reach and uptime. Voltage raised $6 million in January 2022 led by TVP with participation from Google Ventures, Craft Ventures, StillMark, and others, and has since been funded primarily through operational revenue per public commentary.

Voltage competitors and assessment
Company assessmentDirect peers
- BTCPay Server: BTCPay Server is the leading open-source self-hosted Bitcoin and Lightning payment processor, integrated into every Voltage paid plan. A direct alternative to Voltage's hosted offering, primarily competing at the merchant and SMB tier rather than enterprise.
- Bitrefill: Bitrefill operates one of the largest Lightning-based payment services for gift cards, mobile top-ups, and bill pay, and runs significant Lightning node infrastructure. Comparable to Voltage in core Lightning Network capability and developer-first posture, though more consumer-vertical focused.
- Synonym: Synonym provides Bitcoin-native self-custody and Lightning payment infrastructure for enterprises and developers. Direct peer to Voltage in abstracting Lightning complexity, with overlapping customer base in fintech and exchanges.
- IBEX Mercado: IBEX operates a Lightning-first payments and merchant services business with strong presence in Latin America. Comparable to Voltage in offering Lightning node services and payments rails, but with a regional rather than global enterprise focus.
- Lightspark: Founded by David Marcus (former head of crypto at Meta), Lightspark is building enterprise-grade Lightning Network infrastructure for banks, exchanges, and PSPs. Direct competitor to Voltage with very similar target customers (exchanges, fintechs), similar managed-node architecture, and similar go-to-market via enterprise sales.
Emerging players
- Lipa: Lipa is a Lightning Service Provider (LSP) offering Lightning payment gateways and node services, with strong traction in Europe. Comparable to Voltage in offering Lightning infrastructure-as-a-service, but at smaller scale and focused on merchants rather than institutional customers.
- Alby: Alby is a Lightning-native browser wallet and payment infrastructure provider for the Nostr ecosystem. Comparable to Voltage in abstracting Lightning complexity through simple APIs, but primarily developer/consumer focused rather than enterprise.
- Galoy: Galoy is the open-source Bitcoin and Lightning banking platform behind the Bitcoin Beach Wallet and other deployments. Overlaps with Voltage in providing managed Lightning infrastructure, but focused on banking/community deployments rather than enterprise payment integration.
Broad incumbents
- Block (formerly Square): Block operates Cash App with Bitcoin Lightning capabilities and is a key backer of Lightning Labs. It is a much larger incumbent with overlapping Lightning infrastructure goals, but Lightning is one of many product lines rather than the core focus as at Voltage.
- CoinGate: CoinGate is a major crypto payment processor that supports Lightning among other rails. A broader incumbent compared to Voltage with overlapping Lightning capabilities, but Lightning is one of several supported networks rather than the entire focus.

Does Voltage have an API?
Yes. Voltage offers two primary APIs: the Voltage API for node operations (creating, starting, stopping nodes) and the LND Node API (sending/receiving payments, opening channels). The Voltage API uses authentication via x-voltage-auth header with an API key generated from the team's dashboard. The base URL is https://api.voltage.cloud. The LND Node API exposes the full LND API via gRPC (port 10009) and REST (port 8080) protocols, allowing developers to interact with nodes as if running on their own hardware. Both APIs require macaroon-based authentication. A full-feature sandbox environment (MutinyNet) is available for testing before going live. Developer documentation is at docs.voltageapi.com.
