Rejects if the token is not supported._

Parameters

NameTypeDescription

tokenAddress

address

Address of the token that is going to be rebalanced

percentages

uint256[]

A list of percentages, expressed as units in 10000, indicating how to deposit the tokens in each underlying money market. The length of this array is one less than the amount of money markets: the last money market will receive the remaining tokens. For example, if there are 3 money markets, and you want to rebalance so that the first one has 10.5% of the tokens, the second one 55%, and the third one 34.5%, this param will be [1050, 5500].
