If you’re looking for “Sparrow Wallet Recovery”, you have most likely already tried to get back into your Sparrow wallet yourself and hit a wall. Sparrow is a privacy-focused, non-custodial, open-source wallet and the good news: your Bitcoin remains on the blockchain. A lost password, a forgotten passphrase, a partial seed or a corrupted wallet file is an access problem, not a lost-BTC problem. Disclaimer: If you have your entire BIP/SLIP seed phrase or wallet file and password, you can restore the Sparrow wallet on your own. If that path is closed, this section explains where you actually stand and what steps you can take.
Sometimes, but be aware that Sparrow encrypts the wallet file with Argon2, a deliberately slow, memory-hard algorithm designed to make password cracking expensive. A blind brute force is unrealistic, but strategic evidence based approaches can narrow the search enough to yield realistic chances for success.
Often not. Sparrow is non-custodial, so if you still have your full BIP39 seed phrase or (.mv.db) wallet file and password, you can reinstall Sparrow, import and be back in without anyone's help. ReWallet is for the situations where that path is closed: a forgotten password on a wallet whose seed is also gone, a forgotten passphrase, a partial seed or a wallet file that will not open or any other issues where Sparrow DIY recovery fails.
Two common and very different causes: If you used a BIP39 passphrase, remember that Sparrow stores nothing derived from it, so a wrong or forgotten passphrase opens a different, usually empty wallet instead of showing an error. If you did not use a passphrase, an empty balance after restoring from your seed is almost always the gap limit, which is a quick fix. If you believe your passphrase is wrong and you only partly remember it, that is a case we can work on.
We cannot promise it and we will never pretend otherwise. What we can do is assess your case honestly and where a recovery is realistic, attempt it with our own specialized tools. Whether it is feasible depends on what you still have and what you remember. Our assessment is free and we will first evaluate the chances for a recovery before you commit to anything.
These actions commonly reduce the chances of recovering your Sparrow wallet.
At this first stage we only need to understand your situation, not your secrets.
Sparrow encrypts your wallet file with Argon2, so a forgotten password is a hard problem, but not always an impossible one. If your seed is also gone and you remember something about the password, we run the recovery on high-performance, air-gapped hardware, with strategic approaches instead of random brute forcing and work from whatever you can give us to narrow the search.
The seed is the master key to a Sparrow wallet. If you have lost part of it, are unsure of the word order or have a few words missing, a reconstruction may still be possible. Let us know what is still available and we assess the chances for a successful recovery of your Sparrow wallet.
Because Sparrow stores nothing derived from your passphrase, a forgotten one opens a different, empty-looking wallet with no error message or warning after your first attempt. If you remember parts of your passphrase, there is a good starting point to base a wallet recovery on.
A "Failed to open database file" or "Error Opening Wallet" error usually means the wallet file was damaged, not that your Bitcoin are lost. Where the seed is also unavailable, we can attempt to repair the file or recover a working copy from Sparrow's automatic backups.
