get_eth_estimated_fee_per_gas
The get_eth_estimated_fee_per_gas method allows you to get the estimated gas priority fee for an active coin of your choice.
| parameter | Type | Description |
|---|---|---|
| coin | string | Ticker of the coin/asset for which we want to start the gas fee estimator. |
| estimator_type | string | Simple or Provider. If set to Provider, users must set the gas_api setting in their MM2.json file to source recommended fee values from third party providers Infura or Blocknative. |
