Data availability

[Rom3dius]

Stores withdrawals, transfers and deposits in a single postgresql table. Allows to query for a maximum amount of 500 transactions, using the following filters:

• sender
• recipient
• min amount
• max amount
• min timestamp
• max timestamp

Timestamp is created right before insert.

Testing needs work, tests currently fail because test setup is synchronous but pool setup needs async runtime. And of course the missing database. This is the current testing connection string: postgres://kairos:kairos@localhost/kairos
