Gas Limit Change

The default gas limit is 36M and SSV makes it configurable as long as the operator committees converge on the same value.

Warning

Do this only on private operators, and on clusters where you either can control all the operators, or coordinate with them.

All operators in the cluster MUST set the same gas limit. Otherwise, MEV registrations would fail. The validators would eventually not propose MEV blocks and instead fall back to vanilla blocks (non-MEV blocks built locally).

This also applies after the Gloas fork, when the gas limit is sent in proposer preferences, which are signed by the cluster too.

Configuration​

The SSV node registers its validators to MEV relays with a preferred gas limit. From the Gloas fork on, validator registrations stop and the same gas limit is published in proposer preferences instead.

Starting from SSV version v2.1.1 this gas limit becomes configurable:

  • For .env use EXPERIMENTAL_GAS_LIMIT variable
  • For .yaml configuration file use the following
ValidatorOptions:
    ExperimentalGasLimit: 45000000

Gas limit for vanilla blocks (non-MEV blocks built locally) are set by the Execution Node which you should ideally be set to the same value.

Verification​

Before the Gloas fork, you can verify the configuration change works by querying one of the MEV relays used by the operator:

https://<relay-url>/relay/v1/data/validator_registration?pubkey=0x<validator-pubkey>

Validators are registered in a round-robin fashion once an hour, so you may have to wait this long or check more validators.
