Bridge between everiToken and Binance Dex

Get started

1. install dependencies with yarn

2. setup mysql

   Have mysql instance running either with docker or local on machine. Create a database called bnbbridge (which is specified in src/config/development.ts and src/config/production.ts). Make sure the db settings in config file are correct.

   run yarn setup:db to create tables

3. source in environment variables

   • BINANCE_ACCOUNT_WORDS => mnemonic words that controls swap account on Binance chain
   • EVT_ACCOUNT_PRIVATE_KEY => Private key that controls swap account on everiToken public chain
   • PG_BRIDGE_USERNAME => postgres user name for production environment
   • PG_BRIDGE_PASSWORD => postgres password for production environment

   In case of development

   • BINANCE_ACCOUNT_WORDS="dose boring turtle beef mind scheme estate board range beyond wife there blossom cat chronic cloth kid slide toilet elder delay weekend accuse pull"

     In development, this mnemonic words controls the binance swap account address which is tbnb1ltytz6mm37fjpha4gu9zl4plu93fmhgns66ahd.

   • EVT_ACCOUNT_PRIVATE_KEY="5J7UEyddLEsurNWun2Fz41pzR9mdQWzApBosvBsfjuzQN2jE9eo"

     In development, this private key controls everiToken swap account address which is EVT7f6pEXvD8E2mbytzkirYqv9DBxEd7ebDv9TJpQ6kuKPemLtKUY

4. start two listeners (evt and binance)

   • run yarn listen:evt starts the listening process on everiToken public chain
   • run yarn listen:binance starts the listening process on binance dex

5. ready to start swapping between evt and binance dex

   In development, symbol on binance dex for EVT is called MCB-704 (don't ask me why)

   1. Swap EVT to MCB-704. Send your EVT to address EVT7f6pEXvD8E2mbytzkirYqv9DBxEd7ebDv9TJpQ6kuKPemLtKUY (development), in memo, specify your Binance dex address. You will receive same amount of MCB-704 token in the binance address specified.

   2. Swap MCB-704 to EVT. Send your MCB-704 to binance dex address tbnb1ltytz6mm37fjpha4gu9zl4plu93fmhgns66ahd (development), in memo, specify your EVT address. You will receive same amount of EVT.
