Setup

The Nix package manager is used for handling dependencies. The main build can take over 10 minutes the first time it's run, but it should be much faster afterwards.

git clone https://github.com/obsidiansystems/solana-bridges.git
cd solana-bridges
nix-build

Cleanup

The following directories will be populated by various tools used by this repo:

• ~/.ethash
• ~/.ethashproof
• ~/.config/solana
• ~/.cargo
• ~/.xargo

Take caution when removing them since other programs might also be using these directories.
