Crypto wallet recovery services

We recover access to lost or locked cryptocurrency wallets — forgotten passwords, partial seed phrases, damaged devices — and you pay only if we succeed.

Updated July 2026 · KeychainX — Wallet Recovery since 2017

KeychainX has recovered lost Bitcoin and Ethereum wallets since 2017. We are the oldest incorporated wallet-recovery company — founded after we helped a friend recover a Ledger holding 150 ETH — and today we operate as a Swiss AG in Baar, Zug, with a 4.9 rating across our reviews and a presence at conferences from Miami to Singapore. What follows is exactly what we recover, how the process works, and the cases we honestly turn away.

Software wallet password recovery

The bulk of our work is decrypting software wallets where the file survives but the password is lost. Your password isn’t stored anywhere — it only derives the key that decrypts the wallet — so recovery is a targeted search for that password, built from your hints and run on dedicated offline GPU hardware. You never hand over an unlocked wallet. We have custom software that can decrypt your wallet from the password hints you deliver.

• Bitcoin Core — the encrypted wallet.dat, where the master key is protected by SHA-512 key-stretching inside a Berkeley DB file.
• 2014 Ethereum presale — the encseed JSON (PBKDF2-HMAC-SHA256 + AES-128-CBC), our specialty, where a “correct” password often fails on an encoding quirk.
• MetaMask — the encrypted browser vault (PBKDF2 + AES-GCM), recoverable even when you never saved the seed.
• Blockchain.info / Blockchain.com — first and second password, and the old 15–21 word mnemonics the current site no longer imports.
• MultiBit Classic, Electrum, Mist, Geth, Armory and Jaxx — legacy and discontinued wallets we still support.

Hardware wallet recovery

We recover hardware wallets where the seed, passphrase or PIN is the problem — not by “bypassing” the device, which no honest service can do reliably, but by working the parts that are genuinely recoverable. Anyone who promises to crack a hardware wallet’s secure element is not being straight with you.

• Trezor — a forgotten passphrase (the optional 25th word), hidden wallets, and derivation-path confusion between the device and apps like MetaMask.
• SLIP39 / Shamir — rebuilding access from your recovery shares when some are missing or unclear.
• Ledger — limited: an early ETH derivation-path issue (m/44’/60’/0’/index) is recoverable, but a lost PIN with no seed backup generally is not.

Seed phrase and mnemonic recovery

A surprising number of cases aren’t about passwords at all — they’re about a backup phrase that is almost right. We reconstruct partial or out-of-order BIP39 seed phrases, correct wrong or misread words (a 0 written for an O, an l for a 1), and resolve them against a known address so the answer is certain. We also handle the non-standard mnemonics that early wallets used, which don’t import into modern software.

Damaged, deleted and dead devices

If the wallet lives on hardware that no longer works, the coins usually aren’t gone — they’re buried. We take a forensic image of the media and carve the wallet out of it, then recover the password from the reconstructed file.

• Dead or wiped hard drives — deleted wallet.dat files recovered from free space (note: SSD TRIM can make this impossible, so results vary by media).
• Broken or water-damaged phones — extracting the wallet from a device that won’t boot; ship it to one of our labs in Europe.

How our recovery works, and why it’s safe

We never brute-force blindly. You tell us what you remember — a length, a fragment, the language and keyboard you used, the year and the software — and we turn that into a structured search using custom masks and rules rather than an impossible exhaustive one. Those candidates run on our own in-house GPU and FPGA servers, entirely offline. We deliberately don’t use Amazon or Google cloud, because your encrypted wallet should never sit on shared infrastructure that could be compromised. We keep a copy of your file so nothing is ever lost, and the moment a candidate decrypts your wallet and reproduces your known address, we’ve found it.

Original research is our edge

What separates us from a generic “password cracker” is that we study how these wallets were built — and where they were built badly. We’ve documented the weak-randomness flaws in early browser wallets (Randstorm), the full catalog of encoding bugs that break presale passwords, the MultiBit truncation bug, and the derivation quirks across every major wallet standard. That research is why we solve cases other services return as impossible.

What to expect

The process is simple and honest. You send us the wallet file (or details of the device) and what you remember; we give you a candid assessment within about 24 hours, including whether the case is even viable. If we take it, we agree terms in writing first — a success-based percentage, nothing upfront. Recovery time ranges from hours to, occasionally, months depending on the search space. When we succeed, you transfer the coins yourself; we never take custody of your funds.

What we can’t do

We’d rather tell you upfront than take a hopeless case. We can’t help if you only have a public address and no wallet file or seed; we don’t work on wallets bought or downloaded from the web (those are usually forged); and a Trezor or Ledger with a lost PIN and no seed backup is often not recoverable. If your case isn’t viable, we’ll say so — at no charge.
