Why You Should Migrate Old Wallets

Some older wallets used weak random number generators or poor encryption. Expert attackers can predict these older seed phrases. Moving to a modern wallet protects you with BIP‑39/BIP‑44 standards and stronger entropy.

Security • 2025 Standard

Wallet Migration Checklist

  1. Create a new wallet (Trust Wallet, MetaMask, Phantom, Tangem, Ledger/Trezor).
  2. Write down the new 12/24‑word seed on paper or metal. No photos, no cloud.
  3. Do a small test transfer to the new wallet.
  4. Move all funds once confirmed.
  5. Verify balances and tokens have arrived.
  6. Delete the old wallet app/files.
  7. Store the new seed offline where executors can access.

Recommended Secure Wallets (2025)

What to Avoid

  • Old versions of Blockchain.com, Multibit, early web‑generated keys (e.g., MyEtherWallet pre‑2018).
  • Jaxx Liberty and discontinued wallets.
  • Paper wallets or “brain wallets”.
  • Any wallet that doesn’t use a 12/24‑word BIP‑39 seed.

Never type or store your seed phrase on any website, email, cloud, or phone gallery.

Executor Notes
