Incident Response Checklist for a Crypto Wallet

A pre-defined sequence of actions helps you quickly protect what's left, preserve data, and start the review without panic.

Security in cryptocurrency isn't a single setting. A pre-defined sequence of actions helps you quickly protect what's left, preserve data, and start the review without panic. It's better to build a few checks into the operation process itself.

The main thing to know right away: The goal isn't to memorize a hundred threats, but to build a few checks into every major operation: the address, the network, the source of the payment details, the meaning of the signature, and independent confirmation.

Where risk appears

Incident response is a pre-defined sequence of actions: stop the risk, preserve data, protect the remaining assets, notify the right people, and only then analyze the route. Such a checklist reduces chaos.

A pre-defined sequence of actions helps you quickly protect what's left, preserve data, and start the review without panic. Practical security is built on making the right check a mandatory part of the process rather than relying on the user's memory in a moment of haste.

What to do in advance

  1. Check the address, network, and meaning of the operation before signing.
  2. For large transfers, confirm the payment details through an independent trusted channel.
  3. Never share the seed phrase or private keys with third parties.
  4. Use strong 2FA and separate critical access.
  5. After a suspicious signature, check token approvals and the state of the wallet.

What to record

For an initial review, prepare the data in a single message or file — this reduces the risk of losing an important detail:

  • address and network
  • source of the payment details
  • a screenshot or text of the suspicious signature, if the incident has already occurred
  • a list of approvals, if needed
  • time of the event

What to avoid

  • Don't copy an address from transaction history without checking it.
  • Don't sign unclear requests just because they're "fee-free."
  • Don't keep using a seed phrase if it may have been exposed.

Important: no checklist provides an absolute guarantee. Its job is to eliminate the most typical and costly mistakes.

When to do a separate review

Before a large, unusual, or new operation for the team, it's useful to check the process in advance: who provides the payment details, who confirms them, which contract is being signed, and what will happen after confirmation. Such a review is cheaper than analyzing an incident that has already happened.

Frequently asked questions

Is there a single setting that protects against all schemes?

No. The threats vary: an address error, a malicious signature, a seed leak, account takeover. You need a set of simple checks.

Does support or an analyst need the seed phrase?

No. The seed gives control over assets and isn't needed for ordinary support or analysis of the public blockchain.

Does a hardware wallet protect against any phishing?

No. It protects the key, but the user can still confirm a dangerous operation.

In short

A pre-defined sequence of actions helps you quickly protect what's left, preserve data, and start the review without panic. The most useful protection is to make checking part of the normal process before signing or transferring.
