Policy
As outlined in DAO-ratified Lido on Ethereum Block Proposer Rewards Policy, Node Operators participating in the Lido on Ethereum protocol must use a selection of relays from the vetted list of relays, which is maintained on chain (note: the most up to date contract will always be reflected in the Lido Deployed Contracts docs page).
- The “must include some” set of relays are DAO-vetted relays that are considered trustworthy, well-operated, and reliable.
- The “allow” set of relays are DAO-approved, but less well-known or battle-tested relays which can be trialed prior to inclusion in the “must-include” set.
The list is accessible to the public and amendable by the DAO (and the RMC which has been authorized to do so by the DA) in case relays should be considered for addition, e.g. via public request, or relays should be removed e.g. for bad performance.
The full list list can be queried on-chain by using the get_relays() function. This will return an array with the vetted relays, each including a Uri, operator name, is_mandatory flag and description. Relays belonging to the “must include some” list are denoted through when the flag is_mandatory == True .
What does this mean for Node Operators?
Operators are encouraged to use as many of the relays on this list as possible. Node Operators must use at least some of the relays which have a flag of is_mandatory==True. If amenable to doing so, ideally all should be used, in order to promote relay & builder diversity.
Additionally, Node Operators and Relay Operators are suggested to re-familiarize themselves with the expectations as detailed in the Block Proposer Rewards policy, especially sections: Block Production and Relay Troubleshooting and Relay and Relay Operator Responsibilities.
