Orderflow streams and builder-agnostic bundle submission. Submit a backrun bundle once—we fan it out to every active builder on the chain in parallel. Inclusion odds scale with the whole builder market, not a single operator.
The orderflow stream feeds searchers the targets. Bundle submission fans your backrun to every active builder on the chain so inclusion isn't bottlenecked by a single operator.
Low-latency stream of signal transactions for backrun strategies. Multi-region endpoints, SSE and WebSocket transport, with desensitized payloads safe for searcher consumption.
Submit a backrun bundle once. We fan it out to every active builder on the chain in parallel. Whichever builder wins the slot includes your bundle—you don't bet on a single block producer.
Other infra services compete to be the builder—your inclusion is capped by their block share. We sit one layer above and route your bundle to every active builder in parallel. The whole builder market works for you.
Other infra services are themselves builders—your inclusion is capped by their block share. We route to every active builder on the chain in parallel, so inclusion scales with the entire builder market, not one operator.
Target a signal hash and append your transactions. Bundles execute in defined order or revert as a unit—no partial fills, no orphaned approvals, no leaked intent across blocks.
Aggregated signal stream from desensitized sources, normalized into a single bundle-format feed. Originators not visible in the public mempool—an edge that disappears the moment flow goes public.
proxyBid-style bidding with refund handling done at the protocol layer. Searchers compete on value, not infra plumbing. Future: native builder for vertical integration when economics justify it.
BSC has a mature builder market—exactly where fanout meaningfully beats single-builder dependency. Submission and stream are chain-agnostic; new chains are added as integrator demand and builder coverage make the math work.
Closed beta launching on BSC. Fanout architecture targets every active BSC builder; integrations underway.

Stream a signal, build a backrun, submit once—we fan it to every active builder in parallel. You focus on strategy; we handle the network.
Subscribe to the orderflow stream over SSE or WebSocket. Each frame is a desensitized bundle-format signal with the target hash and metadata you need to plan a backrun.
Reference the signal hash, append your tx(s), set revertingTxHashes and maxBlockNumber. Optionally include proxyBid for the auction lane.
Post to a single MEV Labs endpoint. We validate, simulate, and prepare the bundle envelope for parallel fanout—you never manage builder lists yourself.
Bundle is dispatched to every active builder on the chain simultaneously. Whichever builder wins the slot lands your bundle. Inclusion odds scale with the whole builder market.
We don't pick winners on the builder side. The submission layer targets every active builder so your bundle has the best possible chance of landing — no matter who wins the slot.
No allowlist. No preferred operators. Bundles fan out to every active builder simultaneously — whichever wins the slot lands your transaction.
Closed beta on BSC. Onboarding searcher teams, market makers, and quantitative funds first. Applications open when we launch the beta.
