How to enable user-signed PSBT flow for inscription funding

[karthias93]

Hi everyone 👋
I’m building a marketplace where users can create inscriptions directly from their own wallets (like UniSat or Xverse), instead of the admin’s ord wallet paying for the inscription.

The goal is:

Backend (server) prepares the commit PSBT using the user’s UTXOs.

User signs the PSBT in their own wallet (UniSat/Xverse).

After commit tx confirms, the admin wallet performs the reveal transaction to finalize the inscription.

However, the ord wallet inscribe command automatically creates and signs both commit + reveal transactions using the ord wallet’s own funds, and there’s no flag like --commit-txid or --external-psbt to attach a custom commit transaction.

I’ve seen that --dry-run can output the unsigned PSBTs, but it still builds them from the ord wallet’s internal UTXOs.

👉 Question:
Is there currently a way (or upcoming plan) to:

provide a user-signed commit PSBT to ord for the reveal phase, or

use an external PSBT that’s already signed by the user as the commit transaction input for inscription?

Essentially I want users to sign and fund their own inscription, and the admin wallet only handles the reveal.

Any suggestions, examples, or upcoming support for this flow would be super helpful 🙏

Thanks in advance!
