We've updated our methodology for tracking mev-boost rewards between builders and proposers on Ethereum to include additional payment patterns. Previously, we only recognized payments made directly from the builder's address that received transaction fees. Now, we track two new cases:

• Payments from Different Addresses: Builders using different addresses for paying proposers at the end of the block, separate from the address receiving transaction fees.

• Payments via Internal Transactions: Builders paying proposers through an end-of-block transaction to an alternate address, which then sends funds to the proposer via an internal transaction.

These updates were applied retroactively (on 22nd Jan 2024 at 2300 UTC) to our validator rewards database from September 2022, affecting approximately 23,000 blocks, or roughly 0.6% of all blocks since the Ethereum Merge. This change will impact all API endpoints and fields related to Ethereum execution layer rewards, including aggregations and APR values.

You can find details about these changes on our forum here.
