Over $50 billion in crypto is permanently inaccessible because people lost their seed phrases. Whether you lost all of it or just a few words, this guide explains exactly what recovery options exist — and which "services" to avoid.
Recovery depends entirely on how much information you have. Find your scenario below:
You're fine. Enter the seed phrase into a new wallet app (MetaMask for ETH, Electrum for BTC, Trust Wallet for most coins). Your wallet and all funds will be restored. Do this on a secure, offline device or trusted computer. Never enter your seed phrase on a website or into any app you didn't deliberately install.
This is recoverable in many cases. A BIP39 seed phrase uses a specific word list of 2,048 words and includes checksum bits — meaning the missing words can be brute-forced. Missing 1–2 words is straightforward; missing 3–4 is harder but feasible. See the maths below and the legitimate recovery services in this guide.
If the device still works and you know the PIN, you can access your funds directly without the seed phrase. If you don't know the PIN but have the seed phrase, you can reset and restore. If you have neither — it depends on the specific device model; some have known vulnerabilities that specialist firms like Unciphered may be able to exploit.
An encrypted wallet.dat, keystore file, or .json file can often be cracked if you remember part of the password — a rough pattern, prefix, or suffix. Specialist services use GPU-accelerated password cracking. This is distinct from the seed phrase — the file is what's locked, and partial password knowledge significantly helps.
If the seed phrase, private key, hardware device, wallet file, and any written backups are all completely gone with no information to work from, recovery is almost certainly not possible. No legitimate service can recover funds from zero information. Preserve any assets you do have access to, and consider this a learning experience for future wallet security.
BIP39 seed phrases use a specific word list of exactly 2,048 words. Because the phrase also includes a checksum, the number of valid combinations is smaller than you'd expect:
If you know which word positions are missing (e.g., "I know words 1–10 but can't remember 11 and 12"), the search space is far smaller than if you don't know which words are missing. If you have a partial written backup, even one that's incomplete, it dramatically improves recovery odds. Bring all partial information to any recovery service.
These three services have documented track records and verifiable reputations. All charge on success only — never upfront.
One of the most reputable and long-established crypto wallet recovery services. Specialises in encrypted wallet files (.dat, keystore files) where you remember part of a password, and in partial seed phrase recovery where you're missing a small number of words. Works with Bitcoin Core, Electrum, Exodus, and many other wallet formats. Recovery rate varies by case — they assess feasibility before taking on work.
Visit Wallet Recovery Services →A separately operated but similarly reputable service (note: different from walletrecoveryservices.com). Specialises in Bitcoin wallet password recovery, particularly for old-format wallets, encrypted wallet.dat files, and cases where you remember approximate password patterns. Has handled thousands of cases and has publicly verifiable reviews. Contact for a feasibility assessment — they'll tell you honestly if recovery is likely before taking on the case.
Visit Dave Bitcoin →Unciphered is a cybersecurity firm that has publicly demonstrated the ability to exploit vulnerabilities in certain hardware wallet models — including specific Trezor and other devices. If you have a hardware wallet from which you've lost the seed phrase and PIN, but still physically possess the device, they may be able to extract the seed phrase directly from the hardware in specific scenarios. Not a fit for software wallet recovery — their work is hardware-specific.
Visit Unciphered →| Factor | ✓ Legitimate Service | 🚨 Scam |
|---|---|---|
| Payment | Success fee only — nothing until funds are recovered | Upfront payment required to "start the process" |
| Seed phrase | Never asks for your full seed phrase | Asks for your complete seed phrase "to begin recovery" |
| Guarantee | Honest about odds — assesses feasibility first | "100% guaranteed" or "success rate 99%" claims |
| How they found you | You found them via their website or independent reviews | They contacted you via Telegram, email, or social media |
| Screen access | Never asks you to share your screen or install remote software | Asks to "remotely assist" or install TeamViewer/AnyDesk |
| Verification | Identifiable business, published research, verifiable track record | No physical address, vague background, recent fake reviews |
| Wallet file | Works with encrypted wallet file offline — doesn't need keys | Wants you to send crypto to a "recovery address" |
Before spending money on a recovery service, exhaust all self-search options. Check: USB drives, old phones and tablets, physical notebooks, email drafts, photos of written notes, cloud backups (iCloud, Google Drive, Dropbox), browser saved passwords, and password manager vaults. Many people find their seed phrase in an unexpected place.
btcrecover is a free, open-source tool for recovering Bitcoin and many other wallet passwords. It can brute-force passwords with known patterns and recover missing seed phrase words. Requires some technical ability — there are guides on GitHub. Best suited for those who remember a rough password pattern or have partial seed phrase information.
Old phones running MetaMask, Trust Wallet, or Coinbase Wallet may still have the wallet cached if you never deleted the app. If the device still boots, the wallet app may be accessible with biometrics or a cached PIN even without the seed phrase.
Some mobile wallets automatically back up to iCloud (iOS) or Google Drive (Android). If you granted backup permissions when setting up the wallet, the encrypted keystore may exist in your cloud account. Check: iCloud Drive, Google Drive, local backups in iTunes/Finder.
If you're trying to access a wallet that belonged to a deceased family member, the seed phrase recovery process is the same — but you may have better luck finding it than the person who hid it would expect. Check their physical spaces thoroughly: safes, filing cabinets, metal backup plates, and hidden notebooks. Also check their password manager if you have access to their computer or phone. If you need the full picture on claiming a deceased person's crypto — including exchange accounts, hardware wallets, and legal steps — see our Crypto Inheritance Guide.
A seed phrase (also called a recovery phrase or mnemonic) is 12 or 24 random words generated when you create a non-custodial wallet. It encodes the mathematical master key for your wallet. Anyone with your seed phrase can access all your funds on any compatible wallet app, on any device, anywhere in the world. It is the only true backup for a self-custody wallet.
It depends on the coin. For Bitcoin: Electrum or Trezor Suite. For Ethereum and ERC-20 tokens: MetaMask. For Solana: Phantom. For multiple coins: Trust Wallet or Exodus. Most modern wallets use the same BIP39 standard, so your seed phrase will work in any compatible app — you just need to find one that supports your specific coins.
If you're still logged into MetaMask on a device and haven't cleared the browser cache, you may be able to export your private key from MetaMask's settings (Account → Export Private Key — requires your MetaMask password). If you're locked out and don't have the seed phrase, recovery is not possible through MetaMask itself. Check if the wallet is cached on an old device or browser profile first.
A private key is a single key for a single wallet address (a long string of letters and numbers, usually starting with "5" or "K" for Bitcoin). A seed phrase generates multiple private keys — one for each address in your wallet — from a single backup. If you have either the seed phrase or the private key for an address, you can access the funds at that address.
Best practices: (1) Write it on paper and store in multiple secure physical locations (home safe + safety deposit box). (2) Consider a metal backup plate — fireproof and waterproof (products like Cryptosteel or Billfodl). (3) Never store it digitally — no photos, no cloud notes, no password managers. (4) Tell a trusted person where to find it (for inheritance purposes). (5) Never type it into any website or app that you didn't deliberately set up for wallet recovery.
