1. You must use columbus-3-tracking for calculating taxes. This branch adds TaxCaps, TaxRate event in BeginBlocker
2. terrad start --tracking parameter creates the Richlist in the /tmp at the beginning of each day. The more accounts you have, the longer it takes, so you don't have to use them if you don't need it.

FCD requires PostgreSQL as a backend database and TypeORM as an ORM.

postgres=> CREATE DATABASED fcd OWNER terra;

Table schema has to be synced before running Collector by setting synchronize to true. There is many way to configure TypeORM. Example is below:

ormconfig.js

module.exports = {
  name: 'default',
  type: 'postgres',
  host: 'localhost',
  database: 'fcd',
  username: 'terra',
  password: '<password>',
  synchronize: true
}

You shall not use CLI method, and it is good to disable synchronize option after the first sync.

In Terra we use direnv for managing environment variable for development. See sample of .envrc
