@chowbao whenever you merge this PR, do you mind updating the token transfers docs to remove the * from the amount_raw field description? I think it's causing our build pipeline to fail with error

BigQuery error in update operation: The description for field amount is too
long. The maximum length is 1024 characters.
Error: Process completed with exit code 1.

My guess is the special character is somehow messing up the schema update script
