Blocknative's infrastructure delivers maximum value.


Events like NFT drops can be highly lucrative for the special validators chosen to propose these high-value block rewards. Our real-time infrastructure gives you a performance edge during bursts of network congestion and rapid spikes in gas prices, like those seen during a high profile NFT mint, giving you higher profit margins for your validator.

There are only two code repositories: Flashbots and Blocknative’s Dreamboat


47% of the network using relays is entirely dependent on Flashbot’s relay implementation. • The Blocknative Relay is the only open-source relay not based on Flashbots relay code. Relay diversity is critical to your bottom line.

Blocknative Relay FAQs

Blocknative is committed to upholding our relay to commonly adopted community standards.

Yes. We support all Relay API specifications and continue to monitor and make changes as the specs evolve. See our docs here.

We currently use feeRecipient to minimize complexity and cost (by avoiding additional transfer transactions). We do so in a setting where we don't accept externally built blocks. We are moving towards using last transaction payment when our builder starts accepting bundles.

Blocknative has 4 years of experience operating low-latency, highly reliable infrastructure for Ethereum. The Ethereum Foundation, Curve, and Metamask are among the entities that use Blocknative's infrastructure. Blocknative's gas extension is used by 40K+ users and github dependencies on our open source libraries crossed the 8k mark.

Yes. The Blocknative Relay is built upon our open source code Dreamboat. We believe relay diversity to be critical to network resiliency so our team built Dreamboat independent from Flashbots' Relay code to strengthen the health of the network. As of Nov 1, 2022, the Blocknative Relay is the only relay using a non-flashbots based relay implementation.

The Blocknative Relay has a transparent deployment process. For every new release of relay we build the artifacts for that release using Github Actions. Anyone can see these here as our repo is open source.

Yes. Our relay endpoints are documented here. We also have a dashboard page for our relay with useful resources and data for the community.

Yes. The Blocknative Relay filters transactions to/from any addresses on the OFAC SDN list.

Currently, the Blocknative Relay only accepts blocks from the trusted Blocknative Block Builder. We are planning to add external builder support soon.

Yes, if a high severity bug is found the Blocknative Relay would be taken down and the ecosystem would be notified via our Discord. We encourage anyone using MEV-boost to run more than one relay to always have a fallback.

Yes, it is Blocknative's policy to systematically publish an incident report on Discord in case of a major issue. We also regularly post status updates there for the community for non-critical incidents. The Blocknative Relay has not encountered any major bugs since it launched. You can find an example of an incident report in Blocknative's Discord here.





Yes. This is the endpoint

Yes. We do support relay monitoring based on the guidelines set forth by Flashbots and we do not impose rate limiting on monitors.

Connect with us on block building.

We love to talk to individuals and teams that are thinking about block building.

"Decentralization is critical at every level of the Ethereum network – including block building. Our team is opening up access to Blocknative’s real-time Web3 infrastructure in an effort to enable virtually any network participant to become a block builder. Ultimately, our goal is to drive block builder diversity and equitable value recirculation throughout the Web3 transaction supply chain."
