When users execute trades through Coinbase's DEX Trading feature, third-party DEX aggregators routing those trades may retain any price improvement above the quoted price as their own fee, meaning the user does not receive the benefit of a better execution price than quoted.

This provision establishes that a third-party fee in the form of retained price improvement may apply to DEX trades without a disclosed fixed amount or percentage, in addition to the standard Coinbase fee and DEX service fee. The operational significance is that users cannot determine the size of this third-party retention in advance.
The updated fee schedule removes the previously disclosed 1% fee for instant unstaking and replaces it with a variable fee disclosed only at the time you request to unstake. The change also expands instant unstaking fees to apply when converting a pending standard unstake to an instant unstake. Under the revised terms, you will not know the exact fee until you initiate the transaction, which removes the price certainty previously available.
