If the community prefer minimizing the intermediary risk, another possible choice can be our pool locking a small amount of CRV to veCRV (around 1% of our treasury) for 4 years in Curve ourselves. It can provide us up to 2.5x boost for our deposited capital depending on the ratio between veCRV and our deposited idle capital. The small amount of capital investing will significantly improve our performance without adding much fluctation as it only accounts for 1% of our treasury. No additional contract risk is added to our idle capital in this case.
I sincerely suggest the core team and the community to consider my suggestion. It would improve our long-term APR and make our protocol more sustainable.
