Positioning brief — for the Ultra Sound Relay team
Why the models put Ultra Sound Relay at #1 for mev-boost relay for ethereum validators
- market-leading payload volume and market share Claude · Gemini · Grok“Market-leading payload volume share (~34%)”
- non-censoring posture and network neutrality Claude · Gemini · Grok“strict non-censoring posture processing all valid transactions”
- strong rewards and block value delivery Claude · Gemini · Grok“near-tied with Titan Relay on block value delivery”
- multi-year reliability and clean missed-slot record Claude · Grok“multi-year reliability as the post-2022 neutrality leader”
What would move the rank — the models’ fix lines, unified
- no formal SLA or commercial support contract Claude“validators wanting a formal SLA or a commercial support contract won't find one here.”
- unviable for compliance-mandated institutional validators Gemini“unviable for compliance-mandated institutional validators requiring strict OFAC filtering.”
- private implementation reduces software transparency Grok“Private implementation reduces software transparency compared to open forks”

The de facto neutral standard for a typical validator — open-source (built on Flashbots' mev-boost-relay), non-censoring, community-run, and consistently one of the top relays by delivered payload value and market share, with strong public transparency on bids and a clean missed-slot record. Best all-round balance of censorship-resistance, competitive MEV, and reliability.
Gemini Market-leading payload volume share (~34%), exceptional low-latency infrastructure, strict non-censoring posture processing all valid transactions, and robust transparent metrics; near-tied with Titan Relay on block value delivery; assumes staker values network neutrality alongside high MEV returns.
Grok Sustained highest relay market share (~27-34% of payloads) with strong average rewards, fully non-censoring/unfiltered, high unique builder count, 100% of value to validator, self-caps share to limit dominance, and multi-year reliability as the post-2022 neutrality leader
Where Ultra Sound Relay falls short, per the models
- Claude It's a lean volunteer/community operation, so validators wanting a formal SLA or a commercial support contract won't find one here.
- Gemini Lacks transaction filtering, making it unviable for compliance-mandated institutional validators requiring strict OFAC filtering.
- Grok Private implementation reduces software transparency compared to open forks
