Autofarms and other protocols accumulate inSPIRIT by offering winSPIRIT in return for SPIRIT deposits. The protocol introduces an experimental feature, which functions as an autofarm smart contract by converting the deposited SPIRIT into inSPIRIT, and perpetually relocks that SPIRIT every 4 years. The smart contract functions as a one-way swap, where $SPIRIT is converted into the relevant winSPIRIT entitling the holder to various additional functionality (e.g. transferability outside of the protocol). This means the deposited $SPIRIT is locked in that smart contract forever.
