A playful simulation casts a 166,000-neuron fruit-fly model as a customer scanning fictional crypto transactions for MEV sandwiches.

Field notes

The interface models a fruit fly as a mempool-scanning agent, presenting neural activity, decision latency, appetite, and transaction choices as a live simulation. Its menu includes four token-pair scenarios, while the telemetry reports 1,337 simulated sandwiches eaten and 8.42 SOL in simulated MEV. A separate feed control says users can submit a historical transaction for analysis, although the extract does not verify the result of that interaction.
