ETH infrastructure platform Blocknative adds TX bundles, cancellation, and replacement support

Blocknative, a real-time Ethereum (ETH) infrastructure platform, has newly introduced features including transaction bundle send, cancellation, and replacement support for the Blocknative Builder.

Searchers can now submit MEV bundles privately to the Blocknative Builder to be included on-chain.

This market utility builds upon Blocknative’s reliable, real-time infrastructure that is systematically important to the Ethereum ecosystem.

“MEV bundle control is an important element of our block-building capabilities. As Ethereum evolves, we remain committed to providing real-time infrastructure that supports transparency, accessibility, and decentralization block by block. To reduce friction and facilitate adoption, we have prioritized ease of use by ensuring that our API-level implementation is cross-compatible with the broader builder ecosystem.”
– Matt Cutler, CEO & Co-Founder of Blocknative

Searchers can quickly add the Blocknative Builder to their bundle workflow. The bundle RPC endpoint uses direct payments instead of gas prices to make payments conditional on their transaction succeeding, thus avoiding having to pay for failed bids.

With over 269,000 validators connected to the Blocknative Relay via MEV-Boost, searchers can use the Blocknative bundle RPC endpoint to increase their Builder reach and increase the likelihood that their bundles successfully get on-chain.
