# IBT Additional Rewards



Some [ERC4626](https://eips.ethereum.org/EIPS/eip-4626) [Interest Bearing Tokens](/docs/glossary#ibt) may be integrated into a reward program (on any protocol), and holding these IBTs makes the holder eligible to claim rewards. As the PT holds all the IBTs deposited by the users who[ tokenized their yield](/docs/guides/tokenizing-yield), the PT would need to claim these rewards on behalf of the depositors.

For such eligible IBTs, the Spectra protocol can deploy a rewards proxy on top of the associated Principal Token and add the logic to claim these rewards. These rewards would be sent to a Spectra DAO address and redistributed via governance.
