Discovering that your cryptocurrency has been stolen is a devastating experience. Because blockchain transactions are irreversible, there is no bank to call to cancel the transfer. If you suspect your wallet has been compromised, you must act instantly to mitigate the damage. Here is the emergency protocol for what to do if you are hacked.
Step 1: Secure Any Remaining Funds (IMMEDIATELY)
Hackers often use automated scripts (bots) to drain wallets. Sometimes they prioritize high-value tokens and leave smaller altcoins or staked assets for later.
- Create a New Wallet: On a device you know is clean (preferably a new hardware wallet), generate a brand new wallet with a new seed phrase.
- Transfer Everything: Immediately send any remaining coins or NFTs from the compromised wallet to the new, clean wallet. Pay the highest gas fee possible to ensure your transaction is processed before the hacker's bots.
- Abandon the Old Wallet: Once a seed phrase or private key is compromised, the wallet is dead. Never send funds to that address again.
Step 2: Revoke Smart Contract Approvals
If the hack was caused by interacting with a malicious smart contract (rather than a stolen seed phrase), the attacker may only have permission to drain specific tokens.
Go to a blockchain explorer (like Etherscan) or a tool like Revoke.cash. Connect your wallet and instantly revoke all token spending approvals granted to unrecognized contracts. Note: This will not recover stolen funds, but it stops further theft.
Step 3: Document and Report
While the chances of recovery are extremely low, you should create a paper trail for tax and legal purposes (stolen crypto can often be written off as a capital loss).
- Track the Funds: Use a blockchain explorer to follow where your funds were sent. Record the transaction hashes and the hacker's destination address.
- Report to Authorities: File a report with local law enforcement and national cybercrime agencies (like the IC3 in the United States). Provide them with the transaction hashes.
WARNING: The Secondary Scam
After you are hacked, you may desperately search for "crypto recovery experts." Scammers aggressively target hack victims. They will claim they have special software to track and recover your funds, but they will require an "upfront fee" or ask for your private keys. Do not trust them. There is no software that can reverse a blockchain transaction. They will simply steal more money from you.

Frequently Asked Questions
What should I do first if my crypto wallet is hacked?
Immediately transfer any remaining assets to a completely new wallet generated with a new seed phrase on a clean device. Time is of the essence.
Can a crypto transaction be reversed?
No. Due to the decentralized and immutable nature of the blockchain, once a transaction is confirmed, it cannot be reversed, canceled, or refunded by any authority.
Should I trust 'crypto recovery services'?
Almost all 'crypto recovery services' advertising on social media or search engines are secondary scams. They will ask for an upfront fee and deliver nothing. Law enforcement is the only entity you should report the theft to.
