# Daily Updates on Base

All active indices allocations are posted daily on-chain. We use Base for this purpose. To avoid front-running we post daily the allocation of the previous day.

The allocations are posted by the Lucid Oracle 0x09812b11f496830af022dc707fb50b490383971e Looking at the logs of a transaction will read the latest allocation. For instance on this transaction you can see
