This is a simple prototype of an Ethereum crypto wallet that uses ZenGo-X implementation of {t,n}-Threshold ECDSA based on the GG20 algorithm. We point to their Binance academy article for an exmplanation of threshold signatures.

The prototype has the following features:

• For every wallet, n key shares are generated.
• Any n-t out of the n shares can sign a transaction.
• A private key is never generated to create a new wallet.
• The private key doesn’t need to be reconstructed to sign a transaction. \end{enumerate}

Installation

1. Install ZenGo-X implementation in your Home directory.

• Install Rust
• Install GMP library (optionally)
• Clone the repo from manel1874 fork. (Note: this takes into account the updates by narayanprusty)

git clone https://github.com/manel1874/multi-party-ecdsa.git

• Build the project

cargo build --release --examples

For further guidance we refer to ZenGo-X library.

2. Install Python dependencies

Python version: 3.5.* and above.

pip install pycryptodome pycoin nummaster Flask==1.1.4

3. Clone this repo.

Run prototype

• Inside the threshold-wallet main folder run:
