Hello list,

I'm writing this email to announce the launch of bip174.org, a PSBT viewer and editor that runs in the browser. The website itself is pretty simple, you can paste a PSBT to see its content and whenever a change is made to one of the various fields the PSBT is automatically updated. There are a few examples built in if you just want to quickly try it out.

Daniela Brozzoni and I have been working on this tool for a while, mainly because we felt the need ourselves for something that would allow us to easily dump/modify the PSBTs we work with in our day to day job. We are not aware of any other tool that does something similar (`decodepsbt` in Bitcoin Core can only show the content of a PSBT but not change it), so we decided to build this instead, taking inspiration from the great bip32.org.

For anyone who's interested, the webapp is made entirely in Rust compiled to WASM. The source code is available on GitHub.

Contributions, feedback and bug reports are all very welcome!

Alekos
