Bark
Second's self-custodial Ark wallet for apps and agents: the barkd daemon exposes a local REST API (TypeScript, Python and C# clients) to pay and receive over Lightning via BOLT11, BOLT12, Lightning addresses and LNURL on mainnet
Note: Not a Lightning node. Bark runs on Ark, a separate Bitcoin layer run with Second's Ark server, and reaches Lightning through it, so agents can pay and receive Lightning invoices, BOLT12 offers and Lightning addresses. Second's docs MCP server only searches documentation for coding agents; it does not make payments.
