Case Studies
An archive of technical deep-dives, architectural reviews, and data engineering pipelines built by Rantum Studio.
ClearTrace ● Live
Neutral, third-party proof of where DEX volume really originates — surfacing hidden, untagged orderflow plus execution quality and MEV across Ethereum, Base, Arbitrum, and Optimism. Live API + dashboard.
AddressIntel ● Live
Predictive real-estate intelligence fusing fragmented municipal permit records with multimodal AI (Google Gemini) to score teardown probability, flippability, and off-market opportunity. Live B2B API.
DePIN QoS Oracle Prototype
A real-time anomaly-detection oracle that scores the reliability of decentralized GPU compute (Akash, Render, io.net) as a 0–100 Compute Health Score for autonomous AI agents.
Graphify Charts Internal Tool
A FastAPI rendering engine that aggregates Notion databases and streams dynamic, real-time SVG charts directly into Notion embeds.
Detecting MEV & Sandwich Attacks On-Chain ● Live
A practical methodology for detecting MEV and sandwich attacks on-chain — separating real slippage from adversarial extraction, across Ethereum, Base, Arbitrum, and Optimism.
From Fragmented Permit Data to a Teardown-Probability Model Case Study
How AddressIntel unifies building permits from four municipal systems on the parcel APN, engineers a teardown label that is independent of the feature it validates, and backtests it point-in-time — with an honest read on what the model actually beats.
What Won't Change in On-Chain Execution Markets Perspective
Nine structural bets about execution, MEV, and data verification on-chain that don't depend on any specific protocol, model, or chain staying the same.
