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:
