Otherwise, pull requests are appreciated.
Some examples interact (via HTTPS) with a 3rd Party Blockchain Provider (3PBP).
### Warning: Currently the tests use TransactionBuilder, which will be removed in the future (v6.x.x or higher)
We will move towards replacing all instances of TransactionBuilder in the tests with the new Psbt.
Currently we have a few examples on how to use the newer Psbt class at the following link:
