Setup

1. Add wallet key and bybit api key to secrets.json.
2. Choose configuration parameters in config.json.
3. Add RPC endpoint.
4. For new wallets, ts-node src/initialize_accs.ts, this will deposit a specified amount into Zeta DEX.

Run

npm i
ts-node src/app.ts

Remote setup

Expose port 85 used by web APIs.

# allow for port 85 usage
sudo setcap cap_net_bind_service=+ep /usr/bin/node
