How to Test Your Seed Phrase Recovery Without Moving Your Funds? (Performing a Dry Run)

Understanding Seed Phrase Dry Runs

1. A seed phrase dry run simulates the full wallet recovery process using the same 12, 18, or 24-word mnemonic without accessing or transferring any real assets.

2. This method verifies that every word is recorded correctly, in proper sequence, and free from typos, capitalization errors, or omitted characters.

3. It confirms whether the derivation path matches the original wallet’s standard—such as BIP-39 with BIP-44 for Ethereum or BIP-49 for segwit Bitcoin addresses.

4. Performing the test on an air-gapped device eliminates exposure to malware that could intercept keystrokes or clipboard data during input.

5. The entire operation occurs offline; no private keys ever touch a network-connected machine or third-party service.

Required Tools and Environment Setup

1. A clean, offline computer or hardware wallet with verified firmware—never reused after internet exposure without full wipe and reinstall.

2. Open-source wallet software known for deterministic derivation, like Electrum (for Bitcoin) or MyEtherWallet’s offline generator (for Ethereum-compatible chains).

3. Physical paper or metal backup of the seed phrase, kept away from cameras, microphones, or networked peripherals during the session.

4. A second trusted device to cross-check generated addresses—only used to verify public address output, never to enter the seed.

5. Never use browser-based recovery tools, cloud wallets, or mobile apps claiming “test recovery” functionality—they often transmit data or derive keys insecurely.

Step-by-Step Recovery Simulation

1. Boot the offline machine into a read-only OS such as Tails Linux to prevent disk writes or persistent logging.

2. Launch the chosen wallet software in offline mode and select “Restore wallet from seed” or equivalent option.

3. Carefully type each word exactly as written—no auto-correct, no copy-paste, no swapping positions even if two words look similar.

4. Confirm the displayed receiving address matches one previously used in the live wallet—this proves correct derivation and checksum validation.

5. Repeat the process at least twice: once with the exact original spacing and casing, once with deliberate minor variations to observe failure behavior—this builds confidence in error detection capability.

Risks of Incomplete or Misguided Testing

1. Entering the seed on a compromised or internet-connected system may leak the phrase via memory dumps, browser extensions, or keyloggers.

2. Using unofficial forked versions of wallet software can hardcode backdoors or alter derivation logic silently.

3. Assuming checksum validation success guarantees full recovery ignores potential mismatches in passphrase handling or custom derivation paths.

4. Confusing testnet and mainnet address generation leads to false positives—always verify against a known mainnet receive address.

5. Skipping the verification step where you compare derived addresses against historical on-chain activity renders the entire dry run meaningless.

Frequently Asked Questions

Q: Can I perform a dry run using my existing hardware wallet?Yes—if the device supports viewing derived addresses without signing, such as Ledger Live’s “Show address” feature in recovery mode or Trezor Suite’s “Recovery check” tool. Ensure firmware is up to date and avoid connecting to untrusted computers.

Q: What if my wallet uses a passphrase (25th word)?You must include the exact passphrase during the dry run—including spaces, special characters, and case sensitivity. Omitting it will generate entirely different addresses. Store the passphrase separately but equally securely.

Q: Does successfully deriving one address guarantee all addresses are recoverable?No. Deriving the first receiving address only confirms basic BIP-39 parsing and initial derivation. To confirm full compatibility, verify at least three addresses across different account indices and change chains.

Q: Is it safe to take a screenshot of the derived address during testing?No. Screenshots may be cached, synced, or indexed. Use physical notepaper or a dedicated offline device with no storage persistence to record outputs.
