Free Crypto Forensic Tools
Five free, no-signup tools to check crypto safety: validate an address, trace a transaction, screen for OFAC sanctions, value a wallet portfolio in USD, and calculate the USD value of stolen crypto — read live from public sources, right in your browser.
These tools read public data for preliminary, informational purposes only. They are not investigative findings, a risk assessment, or legal/financial advice, and absence of a sanctions match is not a clearance. BlockTrace Forensics does not store anything you enter.
Want the full picture? These tools are a preliminary check. For multi-hop tracing, exchange attribution, and a court-admissible report, start an investigation.

These free tools help you check crypto safety and put a value on it — with no signup and nothing stored. Use the address validator to confirm an address is real, the transaction tracer to look up any transaction hash, the sanctions screener to check an address against the OFAC list, the portfolio valuation to value a wallet in USD, and the loss valuation to calculate what stolen crypto was worth.
Crypto Address Validator
Paste any Bitcoin, Ethereum/EVM or TRON address and the validator verifies its format and checksum entirely in your browser, then tells you the network and address type. It catches typos and fake addresses before you send funds — a single wrong character can send crypto to a dead address forever. Need on-chain details too? Try the free wallet check.
Transaction Hash (TXID) Tracer
Enter a transaction hash and pick the chain (Bitcoin, Ethereum, BNB Chain or TRON) to pull the live details: status, value, sender and recipient, block, fee and confirmations — read directly from public explorers and RPC nodes. For multi-hop tracing across wallets and exchanges, see blockchain tracing.
OFAC Sanctions Screener
Screen any address against the U.S. OFAC SDN list of sanctioned crypto addresses (updated daily). A match means the address is sanctioned and you should not transact with it. This is a first-line compliance check — it covers the OFAC list only and is not a substitute for full screening or legal advice.
Wallet Portfolio Value
Paste a Bitcoin, Ethereum, BNB Chain or TRON address and the tool reads its live holdings and values them in USD using current CoinGecko prices — native coin plus USDT — with a running total. It's a quick way to see what a wallet is worth right now. For balance and activity details, use the free wallet check.
Crypto Loss Valuation
Lost crypto to a scam or hack? Pick the coin, enter the amount and the date it was taken, and the loss-valuation tool fetches the historical price on that date and the current price to show what your crypto was worth then and now — with a downloadable report you can attach to insurance claims, police reports, or legal filings. If you've been a victim, talk to our investigators about tracing and recovery.
When to Use These Tools
- Before sending crypto to an unfamiliar address.
- To verify a payment or refund actually went through.
- To check whether a counterparty's wallet is sanctioned.
- To gather initial evidence after a suspected scam — then talk to an investigator.
Frequently Asked Questions
Are these crypto tools free?
Yes — all three are free with no signup, and nothing you enter is stored.
Which networks are supported?
Bitcoin, Ethereum and EVM chains (including BNB Chain), and TRON. The tracer also covers USDT on these networks.
How does the sanctions check work?
It compares the address against the public OFAC SDN crypto-address list (a daily-updated mirror). It covers OFAC only and is not exhaustive.
Is my data stored?
No. The validator runs entirely in your browser; the tracer and screener query public sources directly. We don't store the addresses or hashes you enter.
How is the wallet portfolio value calculated?
It reads the wallet's live native-coin and USDT balances from public explorers and multiplies them by current CoinGecko prices in USD. It's an estimate of current value, not an audited statement.
What is the loss valuation report for?
It values stolen or lost crypto at the date of the loss and today, so victims have a clear USD figure to attach to insurance claims, police reports, or legal filings. The report is downloadable and informational only — not a formal valuation opinion.
An address is sanctioned or looks like a scam — what now?
Do not transact with it. If you've already lost funds, preserve evidence and contact our investigators for a forensic trace.
