An MEV relay censorship resistance audit checklist before large validator staking deposits turns relay selection from a default configuration into a censorship-resistance decision. The primary keyword is MEV relay censorship resistance audit, and the search intent is protocol infrastructure: verify which MEV relays censor transactions, how many non-censoring relays are available and whether the validator relay configuration maintains Ethereum credible neutrality.
CryptoSigy Radar treats MEV relay censorship resistance as a validator-infrastructure security layer. Since the OFAC tornado cash sanctions, a meaningful percentage of Ethereum blocks have been built by OFAC-compliant relays that exclude certain transactions. A validator that connects only to censoring relays contributes to blockchain censorship.
Audit Which MEV Relays Censor Transactions
Track which MEV relays filter transactions based on OFAC compliance or other censorship criteria. Data from mevwatch.info and similar dashboards show the percentage of blocks built by censoring relays versus non-censoring relays over time.
A validator that connects to five relays where four censor transactions is effectively a censoring validator, even if the validator operator has no censorship intent. The relay selection determines the censorship profile, not the validator intent.
Check Relay Diversity And Market Share Concentration
MEV relay market share is concentrated. A small number of relays build a large percentage of MEV-boost blocks. Check the market share concentration and whether the top relays are censoring or non-censoring. A validator that connects only to the top three relays by market share may have limited censorship-resistance options.
Also check whether the relays are operated by independent entities or share common ownership. Two relays operated by the same entity or funded by the same source may have the same censorship policy even if they appear as separate relay endpoints.
Evaluate The Minimum Relays Needed For Censorship Resistance
A validator needs at least one non-censoring relay in its configuration to have the possibility of including non-censored transactions. But one non-censoring relay may not have enough market share to win blocks regularly. A validator with one non-censoring relay and four censoring relays will still produce mostly censored blocks.
The recommended configuration is to connect to at least three non-censoring relays with meaningful market share. This ensures that the validator contributes to censorship resistance even if one or two non-censoring relays have temporary outages or low block-winning rates.
Monitor For New Relay Offerings And Regulatory Changes
The MEV relay landscape changes as new relays launch, existing relays change policies and regulatory requirements evolve. A relay that was non-censoring last month may implement OFAC compliance next month. A new relay may launch with better censorship-resistance guarantees.
Set up a quarterly relay audit schedule. Review the relay configuration, check for new relay options and verify that the censorship-resistance profile still matches the validator operator intent. Treat relay configuration as a living setting, not a set-and-forget parameter.
- Audit which MEV relays censor transactions and calculate the percentage of censored blocks in the current relay set.
- Check relay market share concentration and common ownership patterns that may create hidden censorship correlation.
- Connect to at least three non-censoring relays with meaningful market share for effective censorship resistance.
- Schedule quarterly relay audits to catch policy changes and new relay offerings.
