Gotham-city, an HD wallet using 2-party ECDSA

Gotham City

Gotham city is a fully functional client/server application of a minimalist decentralized HD wallet using 2 party ECDSA.

Supported Blockchain(s) / Coin(s) Server

Gotham server is coin / blockchain agnostic but Elliptic Curve specific.

List of supported Curve(s):

Client

Gotham client is coin / blockchain specific.

List of supported Coin(s):

Extending the client to support more coin(s) is easy as long as the Elliptic Curve and signing scheme of the new blockchain are supported. In the case a blockchain is using secp256k1 together with ECDSA, the same keygen and signing code can be reused.

Disclaimer USE AT YOUR OWN RISK, we are not responsible for software/hardware and/or any transactional issues that may occur while using Gotham city. Project Status

The project is currently work in progress. For more information you can email us.
