**Update on Holesky Relay Additions** This post is to confirm that the proposal to expand the Holesky “may use” list by incorporating additional relays supporting constraints has been reviewed, with no objections raised by the Relay Maintenance Committee. Accordingly, the following relays will be added to the “may use” list on Holesky. These additions are aimed at enabling and testing preconfirmation flows within the **Protocol Evaluation and Request Coordination Hub (PERCH)** while maintaining PBS compatibility (more on [PERCH here](https://research.lido.fi/t/proposal-perch-protocol-evaluation-and-request-coordination-hub/8306), [and here](https://research.lido.fi/t/perch-request-for-node-operators-to-run-and-test-bolt/8698)). Node operators can now choose to run either the Bolt sidecar or the Commit-Boost with the Bolt module for their preconfirmation testing. **Relays to be Added:** - **[NEW] Chainbound**: `https://0xa55c1285d84ba83a5ad26420cd5ad3091e49c55a813eee651cd467db38a8c8e63192f47955e9376f6b42f6d190571cb5@relay-holesky.bolt.chainbound.io` - **[NEW] Titan**: `https://0xaa58208899c6105603b74396734a6263cc7d947f444f396a90f7b7d3e65d102aec7e5e5291b27e08d02c50a050825c2f@holesky-preconf.titanrelay.xyz` - **[NEW] Aestus**: `https://0x8d6ff9fdf3b8c05293f6c240f57034c6c5244d7ecb2b9a6e597de575b373610d6345f5060c150012d1cc42d38b8383ac@preconfs-holesky.aestus.live` For reference, the [MEV Relay list is viewable here](https://enchanted-direction-844.notion.site/6d369eb33f664487800b0dedfe32171e?v=d255247c822c409f99c498aeb6a4e51d). --- _[View the full topic](https://research.lido.fi/t/rmc-proposal-add-relays-supporting-proposer-commitments-to-the-holesky-allow-list/8992)._
