BTC transaction utils is a small library that helps to create multisig addresses

and to swiftly sign some types of segwit transactions as well as to check the

existing signatures, if required.

Manipulations with segwit transactions are quite complicated, so the main goal

is to provide a simple and clear solution for the most common operations

as mentioned above.

## Features

- Creating of the redeem script, which is used in the multisignature transactions.

- Creating and checking of the applied signatures of the `p2wsh` inputs.

- Creating and checking of the applied signatures of the `p2wpk` inputs.

**Note: This library supports only the `SIGHASH_ALL` type of signatures.**

## TODO

Some features are not implemented at the moment, but are desired in future releases.

Any help in implementation of the below listed items is welcome.

- Implement support for `P2SH-P2WPKH` and `P2SHP2WSH` inputs.

- Implement `TransactionBuilder` which helps to create unsigned transactions.

- Implement support for legacy inputs.

- Implement universal transaction signer which can automatically detect the kind of output

  for the corresponding input.
