Pain Finance is the home for novel Reaper Farm strategies. Strategies on Pain use code that is new to DeFi or uses existing code in unique ways. In order to fully test these strategies, they must undergo production testing. That means they have to actually see real use, ergo Pain.Finance.
To make sure users do not deposit too much into these unique vaults we have implemented deposit caps. These deposit caps grow over the lifetime of the vault and are removed entirely when the vault is proven and moved to the main site. We do this as an additional way to mitigate risk when new vaults are introduced.
Pain Finance is a front-end implementation. This means that when a vault is migrated from Pain to Reaper, users are not required to migrate their funds. The back-end vault remains the same.
