• Production

Set the cost basis for a lot that was received from an external wallet.

Use this when you have records of the original purchase price from an exchange
(e.g., Coinbase, Kraken) but the on-chain data doesn't show it.

After setting the cost basis, all affected gain/loss calculations will be
automatically recalculated.
