ACINQ is a Paris-based Bitcoin technology company and one of the principal implementers of the Lightning Network. It builds and maintains eclair, a Scala Lightning node with a 56-method JSON/HTTP API used for routing and channel management at scale; phoenixd, a self-custodial Lightning server daemon that exposes a 27-endpoint HTTP API plus websocket and HMAC-signed webhooks for merchants and applications; the Phoenix self-custodial mobile wallet; and the Kotlin Multiplatform libraries lightning-kmp, bitcoin-kmp and secp256k1-kmp published to Maven Central. ACINQ also operates its own mainnet and testnet Lightning nodes and acts as a liquidity service provider. Every API is self-hosted software rather than a vendor-hosted SaaS endpoint.
