✨ NAME ✨

sendpsbt — the lowkey RPC command that finalizes, extracts, and sends a partially signed bitcoin transaction (a PSBT, bestie 💅). It's the lightning-sendpsbt manual page, and yes we're getting into it.

🎀 SYNOPSIS 🎀

sendpsbt psbt [reserve]

💖 DESCRIPTION 💖

Okay so picture this: sendpsbt is a low-level RPC command that sends a fully-signed PSBT. That's it, that's the vibe. 🦋

But here's the iconic part — if the PSBT is the same one promised by a channel (you know, via fundchannel_complete), then it'll also get associated with that channel, and it gets re-transmitted if necessary on restart. It remembers. It's loyal. 🫶

  • psbt (string) — the fully signed psbt to be sent. Fully signed, girly. This is not a drill.
  • reserve (u32, optional) — number of blocks to increase reservation of any of our inputs by. The default is 72.

🔥 RETURN VALUE 🔥

Slay, it worked. On success you get an object back containing:

  • tx (hex) — the raw transaction which was sent.
  • txid (txid) — the txid of the tx.

💀 ERRORS 💀

If it flops, one of the following error codes may be returned:

  • -32602 — error in given parameters, or some error happened during the command process. (iykyk, sometimes things just happen 😭)

👑 AUTHOR 👑

Vincenzo Palazzo vincenzo.palazzo@protonmail.com wrote the initial version of this man page, but many others did the hard work of actually implementing this rpc command. Respect the whole squad fr fr. 💜

Bestie reminder: fully signed PSBT only, okay? This is the low-level send, not a vibes-based guessing game. 🙈

And that's the whole page, no cap. This was Core Lightning v26.06.9, LIGHTNING-SENDPSBT(7) — go forth and send that PSBT, you absolute icon. 🍓✨💅
