# Interest Pool

Users who choose not to join the SDP will pay interest on their synthetic assets, and the interest will enter the interest pool. 80% of the interest will be converted to CRF and the converted CRF will be destroyed as another way to support the price of the token. The remaining 20% will be reserved for future maintenance and development.
