# Example: on Cosmos network the base denom is uatom, 1 atom = 1_000_000 uatom
# and 1 atom on Coingecko = $10, and your wallet has 10 atom, or 10_000_000 uatom.
# Then you need to specify the following parameters:
# coingecko-currency = "cosmos-hub"
# base-denom = "uatom"
- # denom-coefficient = 1000000
+ # denom-exponent = 6 # so the coefficient == 10^6 == 1_000_000
# and after that, the /metrics endpoint will return your total balance as $100.
- # Defaults to 1000000
