Testing and implementation

We are calling all validators to test mev-boost on Ropsten and Kiln

mev-boost is ready for testing, and we need you! If you’re a solo validator or node operator, please help us test on the Kiln and Ropsten networks. Let us work together so the infrastructure is ready for the merge, and validators can profit from MEV from their first block.

Follow this guide to run mev-boost, a consensus client and an execution client: https://github.com/flashbots/mev-boost/wiki/Testing - and feel free to reach out if you need any support in this.

• Prysm finished the builder-specs integration, is now testable on the develop branch.
• Teku and Prysm are ready for testing.
