Add Multisig Support
Add support for multisig transactions: https://github.com/iotaledger/wiki/blob/master/multisigs.md
Notes for documentation:
-
A bundle may contain multiple multisig inputs.For parity with the JS lib, PyOTA will only support creating a bundle with a single multisig input. -
A bundle may contain multisig and non-multisig inputs.For parity with the JS lib, PyOTA will not support combining multisig and non-multisig inputs in a single bundle. - If there are any unspent inputs, the change address must be specified explicitly.
