Starknet transactions are priced using a single
max_fee value, which indicates the maximum amount of fees (in
Wei) that an account is willing to pay.
For commands that send out transactions, Starkli needs to come up with this value. By default, a fee estimate is requested from the provider, and a 50% buffer is added on top of the estimate to avoid failures due to price fluctuations.
It's possible to skip the entire fee estimation process by manually providing a
The recommended way to do it is through the
--max-fee option, which accepts a decimal value in Ether (18 decimals). For example, to perform an
ETH transfer with a
starkli invoke eth transfer 0x1234 u256:100 --max-fee 0.01
If you already have the
max_fee value in
Wei, it's also possible to use the raw value directly via the
--max-fee-raw option. An equivalent command to the example above would be:
starkli invoke eth transfer 0x1234 u256:100 --max-fee-raw 10000000000000000
Commands that send out transactions accept a
--estimate-only flag, which stops command execution as soon as an estimate is generated.
