The amount of fees paid in different coins

[bro-n-bro-0]

SELECT 
    height, 
    JSONExtractString(arrayJoin(JSONExtractArrayRaw(JSONExtractString(fee, 'coins'))), 'denom') as denom,
    sum(toUInt256OrZero(JSONExtractString(arrayJoin(JSONExtractArrayRaw(JSONExtractString(fee, 'coins'))), 'amount'))) as amount
FROM spacebox.`transaction` FINAL 
GROUP BY height, denom

Here is a nice example Now we can get all currencies as fee
