<p>I can find some PSBT related pull requests in ACINQ’s Kotlin library, which I think compiles to JRE. BitcoinJ does not have support for PSBTs, judging from this <a href="https://github.com/bitcoinj/bitcoinj/pull/1930" rel="nofollow noreferrer">open pull request</a>. I’m not aware of another Java-based library that has PSBT support.</p>

<p>Does anyone know of a library/method in Java that I can pass a String into and see if it is a properly formatted PSBT in base64?</p>

I can find some PSBT related pull requests in ACINQ’s Kotlin library, which I think compiles to JRE. BitcoinJ does not have support for PSBTs, judging from this [open pull request](https://github.com/bitcoinj/bitcoinj/pull/1930). I’m not aware of another Java-based library that has PSBT support.
