   • EVM chains: For EVM chains, transaction fees vary between the EIP1559 and Legacy methods.

     • EIP 1559

       • Under the EIP1559 method, users can customize 3 parameters: max priority fee (gwei), max fee, and gas limit.
       • The estimated fee is calculated by multiplying the max fee by the gas limit: (max fee * gas limit).
       • For Mantle and Optimism, the displayed fee amount pertains to Layer 2 only. After you submit the transaction, Layer 1 fees will be auto deducted from your source wallet address. Please ensure that your address has sufficient gas tokens to cover all fees.
       • There are no fees for Chiliz, whereas fees apply to Chiliz Chain 2.0.

       Parameter	Definition
       Max Priority Fee	The priority fee, often referred to as the ‘miner tip,’ serves as an incentive for miners to prioritize your transaction. The max priority fee represents the highest amount of miner tips you are willing to pay for your transaction.
       Max Fee	The max fee represents the total gas price you are willing to pay for your transaction.
       Gas Limit	The gas limit represents the max number of gas units you are willing to pay for the execution of a transaction or Ethereum Virtual Machine (EVM) operation. Different operations require varying quantities of gas units.

     • Legacy

       • Under the Legacy method, users can customize 2 parameters: gas price (gwei) and gas limit.
       • The estimated fee is calculated by multiplying the gas price by the gas limit: (gas price * gas limit).

       Parameter	Definition
       Gas Price	The gas price represents the amount of ETH (in a smaller unit known as gwei) that must be paid to validators for processing transactions.
       Gas Limit	The gas limit represents the max number of gas units you are willing to pay for the execution of a transaction or Ethereum Virtual Machine (EVM) operation.

   • UTXO-based chains

     • Users can customize the fee rate (sat/vByte).

     • The estimated fee is calculated by multiplying the fee rate by the transaction size: (fee rate * transaction size).

       Parameter	Definition
       Fee Rate	The fee rate is calculated in satoshis per unit of data that your transaction will consume on the blockchain, abbreviated as sats/vByte.

8. (Optional) Add a transaction category and description to identify this transfer more easily.
   • For Category, either create a new category or select from existing ones. Each transfer can be associated with a maximum of 5 categories. Note that once a category is added, it cannot be edited or deleted. Currently, Cobo Portal allows the creation of up to 200 categories.
     • To view the categories under your organization, click the profile icon in the bottom left corner, then select Organization > Transaction Categories.
   • For Description, add a description with a maximum limit of 100 characters.
