Bottom line: stop the bleeding first, then record and report

"My wallet was emptied." "I sent funds to a fake investment." The moment you notice, the order of actions is fixed: 1) stop further loss → 2) preserve evidence → 3) report to legitimate channels. Sadly, a transfer settled on-chain generally can't be reversed — but you can prevent further loss right now.

Key points

- Top priority: "nothing more gets taken" (revoke approvals, move funds)

- Settled transfers usually can't be recovered — but escalation can be stopped

- Preserve records and report to police, the consumer hotline, and the FSA

- Anyone offering to "recover" your funds is a second scam — never pay or engage

1. Stop further loss (minutes matter)

  • Suspect a compromised wallet: immediately revoke all token approvals and move remaining assets to a fresh wallet. If the seed phrase may be exposed, never use that wallet again
  • Exchange account breached: change the password, reset two-factor auth, and ask the exchange's support to freeze it
  • Stop engaging the scammer: send nothing more, and cut contact

2. Preserve evidence

  • The transaction hash, destination address, time and amount
  • Screenshots of the conversation (their contact, the site URL, any ads)
  • Transfer receipts and exchange history

3. Contact Japan's help lines

For urgent or clear crimes, consider a formal report

For high-urgency situations or a clear crime, also consider filing a formal police report. The National Police Agency also provides a cybercrime consultation channel.

4. Never believe "we can recover it" (the second scam)

Beware recovery scams

People and "services" target victims, claiming they can recover your funds for a fee. This is almost always a second scam. Never pay anything to a "recovery service" that demands an up-front fee, DMs you, or advertises on social media. For legitimate help, use the official channels above.

Prevention (for next time)

FAQ

Q. Will the crypto I sent come back? A. A transfer settled on-chain generally cannot be reversed. That's why the realistic steps are "stop further loss" and "report to official channels."

Q. Can the exchange freeze it if I ask? A. Only if the funds landed at an exchange's address and the exchange could act fast. No guarantees — but contacting them quickly is worth it.
