sellEntireBalanceenumOptionalDefaults to false

If set to true, the taker’s entire sellToken balance will be sold during trade execution. The sellAmount should be the maximum estimated value, as close as possible to the actual taker’s balance to ensure the best routing. Selling more than the sellAmount may cause the trade to revert. This feature is designed for cases where the precise sell amount is determined during execution. Learn more here.
