About
TraceFast is a real-time blockchain analytics and forensics platform built around one idea: the answers you need are in the execution, not just in the address labels.
Most analytics tools compete on how many addresses they've tagged. We compete on how deep you can see. TraceFast indexes full execution traces — every internal call, every state diff, every storage write — within seconds of block production. When you're reconstructing an exploit, tracing stolen funds, or dissecting an MEV strategy, you see what actually happened inside the transaction, not just who sent what to whom.
We own the entire data path
Most analytics products are built on rented infrastructure: third-party RPC providers, external indexers, purchased datasets of unknown depth and freshness. Every layer they don't control is a layer where data can be incomplete, delayed, or silently wrong — and no way for you to verify it.
TraceFast runs the full pipeline in-house, from our own archive nodes to the final query layer. Traces are captured at the execution level as blocks are produced, flow through our own streaming and storage infrastructure, and land in query engines we operate end to end. No chain data is sourced from a vendor, and nothing arrives pre-aggregated from a black box — the only external inputs are public sanctions lists and registries, which we ingest verbatim and attribute to their source.
Why this matters in practice
- Verifiable provenance — every data point can be traced back to raw chain state on our own archive nodes. When your investigation needs to hold up to scrutiny, "we re-executed the block ourselves" beats "our data provider says so."
- Scalable JSON-RPC access — because we run our own nodes and indexes, we can expose archive-grade RPC as part of the product, not as a metered pass-through to someone else's service.
- Arbitrary attributes, on demand — any property of an address, contract, or token that exists in chain state or execution history, we can extract and serve. We're not limited to whatever fields a data vendor decided to include.
- No silent gaps — we know exactly what's indexed, from which block, with what guarantees, because we built every stage.
What the platform combines
- Deep execution traces — complete call trees and state diffs for Ethereum, indexed within seconds of block production
- Evidence-based address labeling — protocol deployments, exchange infrastructure, sanctions data (OFAC, FinCEN), and bridge registries, organized by evidence tier rather than crowdsourced guesswork
- Entity flow analysis — aggregated fund flows between entities, with drill-down from the big picture to individual transactions
- Transparent address clustering — reproducible heuristics with full provenance behind every claim
TraceFast is built for security auditors reconstructing incidents, AML and compliance teams that need defensible evidence trails, and MEV researchers working at the execution level.
About this blog
This is where we publish exploit post-mortems with trace-level detail, MEV research grounded in on-chain execution data, and engineering notes on running a real-time tracing pipeline. Every post draws on the same trace index that runs in the product.
