An adhoc CSV format is supported for non-exchange transactions like mining, gifts, and purchases.

yabc also includes a set of HTTP endpoints that allow for storing data more permanently in a database, sqlite by default. Postgres as a backend is also supported.

TODO

  • [ ] TODO: Support coin/coin trades like BTC/ETH.
  • [ ] TODO: Enable importing from more exchanges (binance)
  • [ ] TODO: Add better historical price lookup support; it is now a stub.
