Securing a Self-Custody Wallet

Recovery words, token approvals and signing requests explained — the practical habits that reduce wallet risk.

All insights

In self-custody, whoever holds the recovery phrase controls the wallet. No legitimate organisation will ever need it.

Practical habits

  • Store recovery words offline and never type them into a website
  • Review and revoke unnecessary token approvals regularly
  • Read signing requests carefully before confirming
  • Consider a hardware wallet for significant holdings

If you suspect compromise, move remaining assets to a new wallet created on a clean device.

Common ways wallets are compromised

  • Fake wallet apps or browser extensions that imitate well-known brands
  • Phishing websites that ask you to "verify" or "synchronise" your wallet by entering recovery words
  • Malicious token approvals that allow a contract to move your tokens later
  • Remote-access software installed at the request of a fake support agent

Before you connect to a new application

Check the website address carefully, download wallet software only from the official source, and be wary of airdrops or tokens you did not expect to receive. When a signing request appears, read what it will allow — an unlimited approval is very different from a single transfer. If something is unclear, cancel and research it first.

Blockchain transactions are generally irreversible once confirmed. Good habits are the most effective protection.
