Free Crypto AML Screening Software for Windows

Most people discover crypto AML screening only after a CEX deposit freeze or a flagged P2P trade. By then, per-address API bills and compliance consultants are already on the table. This guide explains how free AML screening works on Windows, what local desktop tools can and cannot do, and how to screen Bitcoin, Ethereum, and hardware wallets like Ledger and Trezor without recurring fees.

The cost problem with cloud AML APIs

Institutional blockchain analytics platforms — Chainalysis, Elliptic, TRM Labs — are built for banks and exchanges with six-figure contracts. Their self-serve API tiers still charge per lookup, often $3–15 per address depending on chain and depth of hop analysis. A freelancer accepting ten payments a month can spend more on screening than on wallet software.

Browser-based "free" checkers exist, but many are lead-generation funnels: one free scan, then a paywall, or worse, they log addresses you paste and resell aggregate data. For self-custody holders who care about privacy, sending every counterparty address to a random website is a poor trade.

Local desktop crypto AML tools solve the economics differently. They bundle sanctions lists, known-risk clusters, and graph heuristics into an application that runs on your Windows machine. You pay once (or nothing, for genuinely free tiers) and scan as many addresses as you need.

What free AML screening on Windows should include

Not every free tool is equal. Before you trust a result, confirm the software covers these minimum capabilities:

• OFAC sanctions matching — SDN-listed crypto wallets and designated entity addresses.
• Multi-chain support — At minimum Bitcoin and Ethereum; ideally USDT on Tron and ERC-20.
• Hop analysis — Distance scoring from your address to mixer, hack, and scam clusters.
• Mixer exposure detection — CoinJoin, privacy pools, and peel-chain identification on BTC; Tornado Cash adjacency on EVM chains.
• Read-only wallet integration — USB connection to Ledger or Trezor for xpub-based portfolio scans without exposing your seed phrase.
• Offline-capable sanctions refresh — Periodic list updates without requiring a paid API key for every query.

If a tool only checks a static address label database with no graph traversal, it will miss the indirect exposure that causes most CEX deposit freezes.

Local desktop vs browser-based screening

For Windows users in self-custody, local screening is the practical default. You get repeatable bitcoin address checks and Ethereum address risk checks without building a spreadsheet of API charges.

How AegisAML fits the free screening model

AegisAML is a Windows desktop application designed for individuals and small businesses who need real crypto AML coverage without enterprise pricing. Core workflows include:

1. Paste any address — Run a bitcoin address check or EVM scan in seconds.
2. Connect Ledger or Trezor read-only — Derive addresses via USB and audit your full cold-storage portfolio. No seed phrase is ever requested.
3. Review risk categories — OFAC sanctions, mixer exposure, hop distance, and scam-cluster proximity in one report.
4. Export or archive results — Useful documentation if a future CEX deposit triggers a compliance review.

The goal is not to replace a licensed VASP's compliance stack. It is to give self-custody holders the same category of warnings that exchanges see — before coins land in your wallet or hit a deposit address.

When you still need a paid institutional service

Free AML screening has honest limits. Upgrade to a paid provider if you:

• Operate a registered exchange, custodian, or MSB with regulatory reporting obligations.
• Need continuous transaction monitoring across thousands of addresses in real time.
• Must file SARs with pre-formatted case management and audit trails for regulators.
• Require legal attestations or expert testimony tied to a specific investigation.

For personal use, OTC side income, and pre-deposit checks, free AML screening on Windows closes the gap between "hope it's clean" and "verified before transfer."

Setup checklist for Windows users

1. Download from the official site — verify the installer signature and avoid cracked copies that may steal wallet data.
2. Run Windows Defender exclusion only if your security policy requires it; otherwise keep default protections enabled.
3. Update sanctions lists on first launch and schedule weekly refreshes.
4. Test with a known-clean personal address, then a published OFAC-listed address (publicly documented) to confirm detection works.
5. Integrate screening into your workflow: check before every inbound payment and before every CEX deposit.
