/**
|
|
* Psbt class can parse and generate a PSBT binary based off of the BIP174.
|
|
* There are 6 roles that this class fulfills. (Explained in BIP174)
|
|
*
|
|
* Creator: This can be done with `new Psbt()`
|
|
* Updater: This can be done with `psbt.addInput(input)`, `psbt.addInputs(inputs)`,
|
|
* `psbt.addOutput(output)`, `psbt.addOutputs(outputs)` when you are looking to
|
|
* add new inputs and outputs to the PSBT, and `psbt.updateGlobal(itemObject)`,
|
|
* `psbt.updateInput(itemObject)`, `psbt.updateOutput(itemObject)`
|
|
* addInput requires hash: Buffer | string; and index: number; as attributes
|
|
* and can also include any attributes that are used in updateInput method.
|
|
* addOutput requires script: Buffer; and value: number; and likewise can include
|
|
* data for updateOutput.
|
|
* For a list of what attributes should be what types. Check the bip174 library.
|
|
* Also, check the integration tests for some examples of usage.
|
|
* Signer: There are a few methods. signAllInputs and signAllInputsAsync, which will search all input
|
|
* information for your pubkey or pubkeyhash, and only sign inputs where it finds
|
|
* your info. Or you can explicitly sign a specific input with signInput and
|
|
* signInputAsync. For the async methods you can create a SignerAsync object
|
|
* and use something like a hardware wallet to sign with. (You must implement this)
|
|
* Combiner: psbts can be combined easily with `psbt.combine(psbt2, psbt3, psbt4 ...)`
|
|
* the psbt calling combine will always have precedence when a conflict occurs.
|
|
* Combine checks if the internal bitcoin transaction is the same, so be sure that
|
|
* all sequences, version, locktime, etc. are the same before combining.
|
|
* Input Finalizer: This role is fairly important. Not only does it need to construct
|
|
* the input scriptSigs and witnesses, but it SHOULD verify the signatures etc.
|
|
* Before running `psbt.finalizeAllInputs()` please run `psbt.validateSignaturesOfAllInputs()`
|
|
* Running any finalize method will delete any data in the input(s) that are no longer
|
|
* needed due to the finalized scripts containing the information.
|
|
* Transaction Extractor: This role will perform some checks before returning a
|
|
* Transaction object. Such as fee rate not being larger than maximumFeeRate etc.
