Zero-Block Inclusion with AllenHark Relay
A deep dive into how "BlockRunner," an independent MEV searcher, utilized our private transaction relay to bypass public mempools and secure profitable bundles.
The Challenge
In the world of MEV (Maximal Extractable Value), visibility is death. BlockRunner was identifying lucrative sandwich opportunities, but every time they broadcasted their transaction to the public Solana network, they were getting front-run by faster bots or having their strategies copied.
They needed a way to communicate directly with validators (leaders) without leaking their intent to the rest of the network. They also needed assurance that their bundles would land in the very next block—"Zero-Block Inclusion."
The Solution
BlockRunner integrated with the AllenHark Relay via our QUIC protocol interface.
Why QUIC?
Unlike standard HTTPS, our QUIC implementation maintains persistent connections. This eliminates the TCP handshake overhead for every request, shaving precious milliseconds off the transmission time.
The integration allowed BlockRunner to send signed transaction bundles directly to our relay network. From there, our Leader-Aware Routing engine instantly forwarded the bundle to the specific validator scheduled to produce the next block, bypassing the public gossip network entirely.
The Results
The privacy and speed of the AllenHark Relay transformed BlockRunner's operation:
- Eliminated Front-Running: By bypassing the public mempool, their strategies became invisible to competitors until after execution.
- Higher Win Rate: The QUIC connection ensured their bundles arrived at the leader node before competitors using standard RPCs.
- Cost Efficiency: Reduced wasted compute on failed bundles allowed them to bid more aggressively on priority fees.
"The AllenHark Relay is the closest thing to a direct line to the validator. It's fast, it's private, and it just works. My fill rate on atomic arbs has never been higher."
