Implementation
The token wrapper contract is called StableWrapper. Upon wrapping the token, the underlying deposited token will be used for yield farming while the user receives a 1-to-1 wrapped version of this token. The user will not be entitled to any yield unless they stake in the vault contract. To unwrap this token, there will be a 1 day delay in order to allow time for the vault keeper to deposit the underlying token back into the contract to allow for withdrawals to complete.
At the start all tokens will be required to be autostaked so all users will be
entitled to yield. This is handled through the allowIndependence flag on the
StableWrapper contract and may change in the future which will allow the
user to hold the wrapped token in itself.
Upon staking the wrapped token (defined in the StreamVault contract), the user will receive shares representing their stake in the vault. These shares are non-rebasing tokens, meaning their quantity remains constant while the underlying value they represent may change based on accumulated yield.
