Real-time financial intelligence,
extracted from raw blockchain data

OmniSight ingests every USDC transfer on Base Mainnet, decodes the raw EVM payload, and scores wallet behaviour with a trained anomaly model — all visible below, updating right now.

// architecture

Eight stages, ledger to risk score

Every layer designed, deployed, and maintained independently. No managed services — just the raw stack.

Base Mainnet — JSON-RPC via Alchemy

Raw event logs pulled directly from the chain. No intermediary indexer.

web3.py

Airflow DAG — 120s cadence

Incremental checkpointing, idempotent inserts, self-healing on block failures.

Airflow

EVM decoder

32-byte topic fields decoded into wallet addresses, 6-decimal USDC normalisation.

Python

PostgreSQL — partitioned by block range

Sub-second range queries at scale. Unique constraint on transaction hash.

Postgres 15

Feature engineering

Transaction count, total volume, average size — per wallet, computed on demand.

SQL

RobustScaler + Isolation Forest

Unsupervised anomaly detection. Median/IQR scaling resists whale-wallet outliers.

Scikit-Learn

FastAPI gateway

Authenticated and public rate-limited endpoints. Async connection pooling.

FastAPI

Nginx + TLS — always on

systemd-managed, survives reboots, Let's Encrypt auto-renewal.

OCI

Why this matters

On-chain volume keeps growing faster than the tooling to monitor it. Most teams still rely on manual lookups or closed enterprise platforms that take weeks to integrate.

OmniSight is the alternative: a single engineer, an open codebase, and infrastructure that costs nothing to run — proof that real-time risk intelligence doesn't require a six-figure contract or a team.

Operational facts

393,000+ clean records, zero duplicates enforced by DB constraint
9,410 wallets with 2+ transactions, eligible for ML scoring
Model —, retrained on — wallet profiles
API survives reboots — systemd managed
