# Fee Model

Currently, Merlin Chain uses the pre-EIP1559 fee model from Ethereum. When initiating a transaction, users only need to specify the Gas Price and the Gas Limit (which sets the maximum amount of gas that a transaction can consume). Unlike the EIP1559 fee model, users cannot specify the Base Fee and Priority Fee.
