 Just like on Ethereum, OP Mainnet transactions can specify a **priority fee**.
 This priority fee is a price per unit of gas that is paid on top of the base fee.
 For example, if the block base fee is 1 gwei and the transaction specifies a priority fee of 1 gwei, the total price per unit of gas is 2 gwei.
-The priority fee(tip) is an optional component of the execution gas fee and can technically be set to 0.
+The priority fee(i.e. tip) is an optional component of the execution gas fee and can technically be set to 0.
 However, while EIP-1559 does not define a minimum priority fee, certain wallets and mempool implementations (like Geth) may enforce a minimum value. For instance, Geth typically defaults to a minimum priority fee of 1 gwei, but this can be configured to other values.
 
 **The OP Mainnet sequencer will prioritize transactions with a higher priority fee** and execute them before any transactions with a lower priority fee.
