metrics.bridge_tokens_daily holds one row per token per day, totalled up from Transfers. It is keyed on the token_id that already exists in dimensions.tokens, and carries the money leaving and the money arriving as two separate columns.

Columns

ColumnTypeDescription
timestampTIMESTAMPDay the row aggregates, truncated to UTC midnight.
token_idSTRINGToken the row measures. Joins dimensions.tokens.
source_transfer_volumeBIGNUMERICUSD value of the token leaving its chain, counted on the day it left. Empty, not zero, on a day nothing left.
destination_transfer_volumeBIGNUMERICUSD value of the same money arriving, counted on the day it arrived. Leaves out transfers whose arriving token cannot be identified; CCIP arrivals name no token in the event, so this can read below the app table’s arriving figure.

Sample queries

Read one token’s daily bridge activity in both directions.

Notes

There is no single counted-once figure on this table. A transfer touches two chains, so one figure for it cannot sit on a key that names a single chain’s token; count transfers once from Transfers when the question needs it. source_transfer_volume and destination_transfer_volume describe one set of transfers from opposite ends, so adding the two together counts the same money twice.
