Port

The amazing tool provide tickets to cyber network.

Structure

• Postgres DB
• Hasura graphql engine
• ETH network indexer
• Cyber network sender
• API for market data

Usage

1. Fill .env file with necessary credentials

   Filled data is default. Don't touch it without reason.

   POSTGRES_FOLDER=./pdb                                       # dir for the postgres db data
   POSTGRES_HOST=127.0.0.1                                     # host for postgres db
   POSTGRES_PORT=5432                                          # port for postgres db
   POSTGRES_DB=PORT                                            # postgres db name
   POSTGRES_USER=<username>                                    # postgres db user name
   POSTGRES_PASSWORD=<password>                                # postgres db user password
   HASURA_HOST=0.0.0.0                                         # graph-ql engine host
   HASURA_PORT=<port>                                          # graph-ql engine port
   HASURA_GRAPHQL_ADMIN_SECRET=<secret>                        # graph-ql engine password
   
   
   ETH_NODE_WSS=<wss://your_endpoint.xyz>                      # ethereum websocket
   ETH_NODE_RPC=<https://your_endpoint.xyz>                    # ethereum rpc
   RECEIVER=<0x_ethereum_receiver_address>                     # ethereum address
   
   
   CAP_API_HOST=0.0.0.0                                        # market data host
   CAP_API_PORT=<port>                                         # market data port
   
   
   LCD_API=<https://your_endpoint.xyz>                         # cyber LCD API enpoint
   SENDER=<put your mnemonic phrase here>                      # cyber sender address mnemonic
   START_BLOCK=<block_number>                                  # the block for indexer start

2. Run:

   ./start-docker.sh

   This command will export all environment values from .env file and run postgres and hasura docker containers.

3. Go to hasura UI and track all tables

   This is necessary for sender listener if db updated.

4. Turn on port processor

   docker-compose up -d port

5. Turn on API

   docker-compose up -d cap_api

6. Enjoy!

This set of microservices will listen to an ethereum network for new blocks and write to DB blocks and transaction to address you use with correct conditions:

• transaction contain cyberadress in data
• this is not zero-value transaction
• transaction executed by contract (status: success).

The cyber network sender will listen to new transactions in DB and send eul tokens for addresses in eth transaction data by implemented formula.
