Incident intake & evidence preservation
Build an incident timeline, preserve original transaction hashes, record chain IDs, UTC timestamps, token contracts, screenshots and communications. Never collect seed phrases or private keys.
Read a transaction from first principles
Separate transaction hash, block, sender, recipient, value, fee, nonce, execution status and event logs. Distinguish a successful transaction from a successful token transfer.
Decode token transfers and approvals
Inspect ERC-20 Transfer and Approval events, token contract identity, decimals, spender permissions, allowance changes and suspicious approvals. Do not infer token identity from ticker symbols alone.
Build a wallet relationship graph
Represent wallets and services as nodes, transfers as directed edges. Track first-seen time, amounts, assets, transaction IDs, hop count and confidence. Common funding or timing is a lead, not proof of common control.
Follow bridge movements
Match source and destination events using bridge contract, message or nonce identifiers, asset mapping, amount after fees and timestamp windows. Do not match transfers by amount and time alone.
Recognize obfuscation patterns
Study peel chains, fan-out/fan-in, rapid consolidation, swaps, liquidity pools, privacy tools and repeated address cycles. Describe observed behavior precisely; avoid unsupported claims about identity or intent.
Identify exchange and service touchpoints
Assess public labels, deposit patterns, address reuse and service-specific transaction behavior. Record the source and date of every label. Only the service can confirm account ownership.
Correlate public information
Build a source matrix for domains, public statements, company records, usernames and breach disclosures. Separate direct evidence, corroborated inference and unverified leads.
Prepare an evidence-led case report
Write an executive summary, incident timeline, wallet inventory, transaction graph, evidence register, confidence ratings, unresolved questions and requested preservation action.
Test your investigation judgment
A wallet sends funds to a deposit address publicly labeled as an exchange. What can you safely conclude?

Trace & evidence workspace
Trace a transaction
Enter a public wallet address or transaction hash.
From transaction hash to evidence trail
Start with a public wallet address or transaction identifier. Verify the network and transaction in an independent block explorer, then record each confirmed movement below. This workspace organises evidence; it does not identify a wallet owner or independently prove criminal conduct.
Build a trace worksheet
Record each observed transfer as a separate evidence row. Keep the transaction hash and source chain with every claim.
What to preserve
Keep the original transaction hash, network, block height, UTC timestamp, token contract, amount, source and destination addresses, explorer URL, screenshots and the reason each transfer is relevant. Record facts separately from assumptions. Never enter seed phrases, private keys, exchange passwords or recovery codes.
Protect your wallet before attackers reach it
Never disclose your recovery phrase, private key, wallet password or one-time authentication code.
Legitimate exchanges, wallet providers, investigators and government agencies do not need your secret recovery phrase to verify a transaction or investigate a theft.
Check before you connect, sign or send
Suspicious URL pattern checker
Inspect a URL for common phishing signals directly in this page. No URL is uploaded by this checker.
This checks visible URL patterns only. It does not query domain reputation, inspect website code or certify a site as safe. A clean result is not proof of legitimacy.Compare two wallet addresses
Check whether a candidate address resembles a trusted address while still being different. This helps expose look-alike addresses inserted into transaction history.
The comparison is character-based. It does not prove that either address belongs to a person or service, or that it is valid on a particular network.Transaction approval pre-flight
Check the details you should understand before approving a transaction or message signature.

Mark the protections already in place. Your progress is calculated locally in this browser.
Understand the attack before it happens
If you suspect your wallet is compromised
If malware, remote-access software or a suspicious browser extension may be involved, disconnect the affected device from the network. Do not create a new wallet or enter a recovery phrase on that device.
If the recovery phrase or private key is exposed, create a new wallet with a newly generated phrase on a trusted, uncompromised device or genuine hardware wallet. Move remaining assets to the new wallet. Prioritize valuable assets and verify the destination carefully. A compromised phrase cannot be made safe by changing a password.
From a clean device, review token allowances and NFT operator approvals on the correct network. Revoke suspicious permissions using a trusted wallet interface or verified block explorer. Revoking is an on-chain transaction and usually costs gas. Disconnecting a dApp alone does not revoke token allowances.
Contact the exchange, wallet provider or payment provider through independently verified official channels. Request an account lock, withdrawal hold, session revocation or preservation of relevant records where available. Never transfer funds to a so-called safe wallet provided by support.
Save transaction hashes, wallet addresses, network names, UTC timestamps, token contract addresses, URLs, emails, chat exports, phone numbers, screenshots and support ticket IDs. Do not edit original evidence files.
Report to your local police or cybercrime authority and the relevant exchange. Include transaction IDs, amounts, assets, addresses, dates, platform names and communications. Report fraudulent domains to the appropriate national cyber-security response team.
Do not pay advance taxes, unlock fees, tracing deposits or guaranteed recovery fees. Treat unsolicited recovery agents and people claiming to be law enforcement with extreme caution.
Create an incident evidence record
Enter non-secret incident details to prepare a structured report you can save and share with an exchange or authority. Never enter a recovery phrase, private key, password or authentication code.

Recent warnings worth reading
Tampered hardware wallets reported
Police warned about cases involving hardware wallets allegedly containing malicious components capable of capturing recovery phrases or private keys. Buy through authorized channels, inspect device integrity and never enter a recovery phrase into a suspected device.
Permit signatures and malware-assisted wallet theft
Police described scams in which fake video-call updates delivered malware, followed by social engineering that induced victims to sign Permit messages. An off-chain signature can grant future token spending authority without an immediate transfer.
Approval phishing investigations
Chainalysis described approval-phishing operations that combine social engineering with on-chain spender and consolidation infrastructure. A single approval can expose a token balance to later transfers.
Scam operations are becoming industrialized
Chainalysis estimated $17 billion in crypto scam and fraud losses during 2025, with impersonation scams and AI-enabled tactics expanding. Treat polished interfaces, deepfake video and social proof as weak trust signals.

What to do after crypto is stolen
Seed phrase or private key exposed
Assume the wallet is permanently compromised. Do not reuse the seed phrase. Never share it with anyone claiming to investigate.
Tokens drained after a signature
Identify the approval transaction and spender contract. Revoke remaining allowances through a trusted chain-specific interface.
Exchange account takeover
Contact the exchange through its official website, secure the email account and preserve login alerts and support case numbers.
Fake investment or recovery scam
Stop sending funds. Preserve conversations, payment records, websites and account details. Report the fraud and any follow-on recovery scam.
Protocol or smart-contract exploit
Record contract addresses, block numbers, event logs and affected transactions. Follow official project incident updates.
Funds moved across networks
Record both sides of every bridge transfer and the matching timestamps. Do not assume similarly sized transfers are linked without evidence.
