It's a backwards compatible change to the PSBT standard defined by BIP174 [1]. Its main benefit is the ability to add new inputs and outputs to a transaction. There's a Bitcoin Core pull request #21283 implements support [2], but has seen very little review so far. Being able to test it against other implementation would aid in review. So which projects are using PSBTv2 or would very much like to? So far I've learned that Core Lightning uses it. They convert it back to v0 when interacting with Bitcoin Core, which they find suboptimal [3]. Feel free to answer here on Stack Exchange [4]. Kind regards, Sjors Provoost [0] https://github.com/bitcoin/bips/blob/master/bip-0370.mediawiki [1] https://github.com/bitcoin/bips/blob/master/bip-0174.mediawiki [2] https://github.com/bitcoin/bitcoin/pull/21283 [3] https://github.com/bitcoin/bitcoin/pull/21283#issuecomment-2597171643 [4] https://bitcoin.stackexchange.com/questions/125384/who-uses-or-wants-to-use-psbtv2-bip370 -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
