Plastron is a free, lightweight alternative to enterprise blockchain-forensics suites for individuals: it screens a wallet for sanctions, mixer and stolen-fund exposure across seven EVM chains, though it is informational, not court-grade forensics.

Blockchain forensics refers to the application of analytical techniques to trace on-chain transactions, identify the entities behind wallet addresses, and build an evidentiary picture of fund flows. In the enterprise market, this capability is dominated by Chainalysis, Elliptic, and TRM Labs — firms that have spent years building address attribution databases, training cluster analysis models, and integrating with law enforcement and regulatory data sources. Their tools are essential for large-scale investigations and regulatory compliance at major exchanges, but they are priced for institutional budgets. Annual contracts for enterprise blockchain forensics tools start in the mid-five figures and scale into six figures for high-volume plans. This pricing structure leaves a significant gap in the market: individuals, small businesses, compliance officers at smaller firms, and crypto developers who need wallet-level risk intelligence for spot checks and pre-transaction screening often cannot justify the enterprise cost. Plastron fills the lower end of this spectrum. It provides the core screening capabilities that cover the most common compliance use cases — OFAC sanctions screening, mixer and darknet exposure checks, stolen fund links, and a composite risk score — without a contract or subscription. The trade-off compared to enterprise tools is scope: Plastron covers Ethereum mainnet, analyzes up to 1,000 recent transactions, and applies one-hop counterparty analysis. Enterprise tools cover dozens of chains, trace fund flows five or more hops deep, and apply machine learning cluster analysis. For pre-deposit screening, self-assessment, and first-line due diligence, Plastron provides enterprise-equivalent intelligence where it matters most.
