Mnemonic recovery
Mnemonic phrase recovery (partial seed)
We recover missing or unclear words in mnemonic phrases of different standard lengths (typically 12 or 24 words; also 15 / 18 / 21 when your wallet used them), fix wrong or unknown word order, and work across BIP39 wordlists and wallet families. Heavy combinatorial search and checksum checks run offline on isolated hardware after scope and contract. Optional BIP39 passphrase (“25th word”) cases are scoped when you have partial rules. Nothing is uploaded to this site — start with a description, not the full phrase.
What we help with
- One or more unknown word positions in a BIP39 phrase when you know the length (12 / 15 / 18 / 21 / 24) and as much of the rest as possible.
- Words are known but order is wrong or you are unsure which slot a word belongs in (permutation-style cases within agreed limits).
- Substitutions from the same wordlist — similar BIP39 words, typos, handwriting misreads — when we can narrow candidates.
- Optional passphrase cases (sometimes called a 25th word / extension word) when you remember part of it or a pattern, not the full secret in chat.
- When you can share a checksum-valid partial phrase or tie candidates to a known address, xpub, or derivation path (after agreement), we use that to cut the search space.
Protocols, wordlists, and wallets
Most wallets rely on BIP39 with English or localized wordlists (e.g. Russian, Spanish, Portuguese). Some products add SLIP39 Shamir shares or vendor-specific dictionaries — we align the technical scope with your wallet and backup format before any large search. You never need to paste a full seed into this page; word count, language, and gap positions are enough for a first assessment.
Ethics and scope: we only work on phrases that belong to you and that you can explain. We do not “recover” seeds from leaks, screenshots of strangers’ backups, or third-party wallets. If the material did not originate with you, we will decline.
Describe your mnemonic case
We typically reply within one business day, often faster. Send your draft by email or Telegram using the contacts on our home or contact page.
How the process works
- Initial review: word count, which positions are unknown, wordlist language, and whether an address/xpub can narrow candidates.
- Agreement on scope, confidentiality, pricing (usually success-based), and a secure channel for sensitive material.
- Offline search and verification on isolated hardware; you confirm access on your side before any success fee.
Same standards as our other services
Transparent scoping, no cold outreach or upfront “guaranteed” recovery spam model, success-based fee after you verify the result.
