These pages are intended to be available for testnets only. Therefore they are disabled by default and need to be enabled via the frontend.showSubmitElRequests setting if wanted.

  tests:
    - { file: "https://raw.githubusercontent.com/ethpandaops/assertoor/refs/heads/master/playbooks/dev/fund-wallet.yaml", config: { targetAddress: "0x332E43696A505EF45b9319973785F837ce5267b9" } }

change the address (0x332E43696A505EF45b9319973785F837ce5267b9) in both assertoor tests to a test test wallet you control.

2. Start devnet with make devnet-run

3. Open dora & wait for epoch 1

4. Navigate to Submit Consolidation page, connect your test wallet and try consolidating some validators :)
