Mobile wallets
Noah
A full-stack mobile Ark wallet, pairing a React Native app with its own Rust backend for account flows and Lightning integration.
Arké
A design-led native iOS wallet that brings bitcoin.design’s open-source UX to life, and forges new ground for Ark-native patterns.
Rebel
A native iOS wallet from Mutiny’s Ben Carman, built with Rust Multiplatform to bring Ark, Lightning, and Nostr together in a single app.
Cypher Box
A three-tier wallet that scales with you: Lightning Accounts on Coinos and Strike, hot self-custody, and air-gapped cold storage.
Satsigner
A Sparrow-style mobile signer with visual UTXO control, full multisig PSBT workflows, and Nostr-based label sync across devices.
Web wallets
Hal
A whole wallet in a single HTML file, from Coinos creator Adam Soltys, speaking MuSig2 and gRPC directly to the Ark server.
Node
Bark Wallet
Send and receive bitcoin across Lightning, Ark, and on-chain from a single, simple wallet that uses barkd under the hood. One-click install from your Umbrel app store.
API and CLI
Bark
The reference Rust implementation of the Ark protocol. Includes a CLI wallet, and the engine inside Barkd and every Bark SDK.
Barkd
Bark as a long-lived daemon, exposing a REST API for backend services and integrations.
Payment processing
BTCPay Server plugin
Add self-custodial Lightning payments to your BTCPay checkout without running a Lightning node or managing channel liquidity.
ArkAPI
A pay-per-call API gateway for AI agents. Sats-metered sessions over Ark or Lightning, with no signup or API keys.
arkzap-me
A self-hostable LNURL server that gives any Bark or Arkade address a deterministic Lightning address, with Nostr zap support built in.
qpayd
Bitcoin payments without the heavy box: a small Rust daemon that locks fiat prices, tracks invoices, and dispatches signed webhooks.
Built something on Bark? We’d love to feature it. Tell us about your app on the community forum or in our community chat.
