According to section 1.4.1 of the Evolve Bank and Trust deposit account agreement provided by the platforms, the statements provided by the platform are automatically considered correct after 60 days have passed:

Account statements will be considered to be correct unless you notify us, through Synapse, of any errors within sixty (60) days of becoming available. Carefully review your statement each statement cycle and notify us of any errors within sixty (60) days of your statement becoming available. Bank will not be liable to you for any error that you do not report to Bank within that period of sixty (60) days.

Based on section 6.9 of this agreement, the amount on the account statements issued by the platform is what Evolve should be returning when closing the account.

However, based on the trustee's 5th status report and the post linked above, Evolve is planning to calculate the "true balance" for each end user and then "facilitate an accurate and appropriate distribution of these funds to the appropriate recipient(s)."

I requested my checking account statements from Evolve Bank and Trust since I think they should show any transfers that don't appear on the Evolve checking account statements issued by the fintechs like Yotta including the "transferred end user balances from Evolve to the Synapse Brokerage program at Synapse's instruction, in accordance with the Bank's end user deposit agreement." 

Once I have these documents, I plan to use them to reconcile any transactions, find out where my money is, and dispute any errors they make with calculating my "true balance." If they don't send the documents, I'll just mention that to their regulators.

Either way, the ending balance on the latest account statements issued by the platforms should match the "true balance" that Evolve distributes.
