Seed Phrase Recovery Service — Missing Words, Typos, and Wrong Order
In one paragraph. If your BIP-39 seed phrase will not import — because a word or two is missing, misspelled, or out of order — your coins are very often still recoverable, because the problem is usually imperfectly recorded information, not lost information. This is a non-custodial technical service: we reconstruct the seed and deliver it to you encrypted, and you open your own wallet. We never take custody of your funds, we never guarantee a result (cryptography is deterministic; outcomes are probabilistic), and we assess feasibility before you pay anything. This page explains what we handle, what the mathematics says about your odds, what we need from you, and what it costs.
1. What this service is — and what it is not
Seed phrase recovery is a technical reconstruction of a BIP-39 recovery phrase that is incomplete or slightly wrong, performed for the verified rightful owner of the wallet. The keys, and the coins they control, are on the blockchain regardless; the seed is how you reach them, and a seed recorded with a small human error can usually be re-derived.
It is not hacking, it is not custody, and it is not a guarantee. Three principles hold throughout:
- Non-custodial. We recover the seed and deliver it to you securely. You access the wallet and move the funds yourself. At no point can we move your funds.
- Assessment-first. We evaluate the realistic feasibility and quote you transparently before any engagement. If the maths says your case is unlikely, we tell you before you spend anything.
- Owner-only. We work for verified rightful owners. Ownership verification is part of the process — it is what protects your wallet from anyone else attempting the same thing.
2. What we handle
| Problem | What it means | Where to read more |
|---|---|---|
| Missing words (1–5) | You have 11/12, or 19–23/24 words; one or more are gone | This page (§3) and, for 4–5, the Tier 3 guide |
| Typos & visual errors | A misspelled or non-existent word, autocorrect, handwriting misread (b/d, 1/l, rn/m, a/o) |
Seed Phrase Typos or Wrong Order |
| Wrong word order | All words correct, sequence uncertain | Seed Phrase Typos or Wrong Order |
| Funds not showing after restore | Seed is fine, but the wallet shows zero — usually a derivation-path issue | Funds Not Showing? Derivation Paths |
| Forgotten passphrase (25th word) | An extra secret on top of the seed | BIP-39 Passphrase (25th Word) Recovery |
This page focuses on missing words; the linked guides go deep on the others.
3. Missing words — what the mathematics actually says
The feasibility of a missing-word case is not a matter of opinion or track record — it is arithmetic, and you can understand your own odds from it.
A single missing word means trying every word in the 2,048-word BIP-39 list at that position until one produces your known address. Each extra missing word multiplies the work by 2,048, and the checksum (which rejects about 15 of every 16 wrong twelve-word guesses, and 255 of every 256 wrong twenty-four-word guesses) does much of the filtering for free.
| Missing words | Candidate space (positions known) | Hardware | Realistic feasibility (with known address) |
|---|---|---|---|
| 1 | 2,048 | Laptop | Near-certain — only thousands of candidates, the checksum and your address pin it down |
| 2 | ~4.2 million | Laptop | Very strong — minutes of work |
| 3 | ~8.6 billion | Multi-core CPU | Strong — minutes to a few hours |
| 4 | ~17.6 trillion | GPU | Case-dependent — feasible with known positions and address; see Tier 3 |
| 5 | ~36 quadrillion | GPU farm | Hard — sometimes infeasible; honest scoping essential |
Two things move you up or down this table:
- A known verifying address (or
xpub) is what lets a reconstruction recognise the right answer. Without it, even a found phrase cannot be confirmed. This is the single most valuable thing you can provide. - Known missing-word positions keep the search small. Unknown positions multiply the candidates by the number of possible placements.
We do not publish a single "success rate" figure, because it would be misleading — your odds are a property of your case (how many words, known positions, a verifying address, standard path, no passphrase), and the table above lets you see honestly where you sit. Four and five missing words move into GPU-assisted Tier 3 work, with its own honest no-find-no-fee structure.
4. What we need to assess your case
To give you an honest feasibility read and a transparent quote, we ask for:
- Network — Bitcoin, Ethereum, Litecoin, Dogecoin, etc.
- Wallet / app — Electrum, Exodus, Trust Wallet, Bitcoin Core, Ledger, Trezor, and so on.
- Seed length — 12, 18, or 24 words.
- Number of missing / uncertain words — and their positions if you know them (the last word, which carries the checksum, is often the most tractable).
- BIP-39 language — English, Italian, Spanish, French, etc.
- A verifying address or
xpub— optional but enormously helpful; it is what confirms a match.
You do not send your full or partial seed phrase at first contact. A one-paragraph email describing the situation is enough to begin.
5. What affects price
Pricing follows computational complexity, not the value of your wallet — we charge the same to recover a small wallet as a large one. The drivers:
- Number of missing words — more words mean exponentially more candidates.
- Position uncertainty — unknown positions widen the search.
- Language uncertainty — testing several wordlists increases scope.
- Derivation-path complexity — custom paths need extended scanning.
- GPU requirement — four to five missing words need GPU acceleration (Tier 3).
Indicative pricing
These are indicative figures confirmed in writing in your engagement letter before any work begins. Success fees, where they apply, are charged only on successful recovery.
| Case | Indicative price |
|---|---|
| 1 missing word | £300 |
| 2 missing words | £600 |
| 3 missing words | £1,200 |
| 4 missing words (GPU) | £3,000 |
| 5 missing words | £2,000 + 15% success fee |
| Typo correction (1–2 words) | £400 |
| Wrong order (12-word) | £800 |
| Wrong order (24-word, partial known order) | £2,000 |
All prices include technical assessment, execution, progress updates, and secure delivery. A truly random full 24-word permutation is not computationally feasible and we will say so rather than quote it.
6. What we do NOT do
- ❌ We do not guarantee recovery — cryptography is deterministic; outcomes are probabilistic. We give honest feasibility, not promises.
- ❌ We do not take custody of your funds at any point.
- ❌ We do not ask for your full seed phrase by email, chat, or web form.
- ❌ We do not use web-based tools or expose seeds online.
- ❌ We do not work on blind or random attempts — assessment comes first.
- ❌ We do not provide financial or legal advice.
- ✅ We do provide technical recovery to verified rightful owners only.
7. When recovery is NOT realistic — and we will tell you
We decline or advise against cases when:
- There are too many unknowns — for example, 6+ missing words with no verifying hints.
- Ownership cannot be verified.
- The computational requirement is extreme relative to the wallet's value.
- There is no address or
xpuband no other way to confirm a candidate. - Several problems stack — missing words and wrong order and unknown language.
- The circumstances raise ethical or legal concern, or a "guarantee" is demanded.
In each of these we communicate a realistic feasibility read derived from the mathematics, and if it is low we advise you honestly before any payment.
8. Supported wallets
Software (BIP-39): Electrum, Exodus, Trust Wallet, Atomic, Coinomi, MetaMask, MyEtherWallet, Bitcoin/Litecoin/Dogecoin Core, and any BIP-39-compliant wallet.
Hardware (seed recovery, not PIN unlock): Ledger (all models), Trezor (all models), KeepKey, SafePal, and other BIP-39 devices. Seed recovery works independently of the device — we recover the recovery phrase, not the device PIN. See the Hardware Wallet Recovery guide.
9. How it works
- Tell us the situation — a short email: network, wallet type, seed length, how many words are missing or wrong. No seed material yet.
- Free technical assessment — we evaluate feasibility from the mathematics, give you a realistic read and a transparent quote (typically within 15–30 minutes for standard cases).
- Controlled recovery — on a written engagement and after ownership verification, the reconstruction runs offline, with encrypted communications and progress updates.
- Secure delivery — the recovered seed is delivered to you encrypted. You verify it, restore your wallet yourself, and move funds to a fresh wallet.
10. Frequently asked questions
Do you guarantee recovery? No. Cryptographic systems are deterministic and do not allow guaranteed outcomes. We provide an honest feasibility assessment grounded in the mathematics of your specific case — number of words, known positions, a verifying address — not a promise and not a marketing percentage.
Do you need my private keys?
No. For seed recovery we need the incomplete seed (only once a written engagement is in place) and a verifying address or xpub. We never ask for private keys, and never for a full seed by email, chat, or form.
Can you steal my crypto? No. The service is strictly non-custodial — we recover the seed and deliver it to you; you access the wallet. We never have the ability to move your funds.
How long does it take? It depends on the case: one or two missing words can resolve in minutes to a couple of hours after assessment; three words in hours; four to five words need GPU time measured in hours to days. We give you a realistic range at assessment.
My seed imports but the wallet is empty — is that a missing-word case? Possibly not. An empty wallet from a complete seed is often a derivation-path issue (Funds Not Showing?) or a forgotten passphrase, both of which are different workstreams. Tell us the symptoms and we will route correctly.
Which jurisdictions do you serve? The UK, the EU, and most jurisdictions where we can complete sanctions and money-laundering checks. We do not currently engage clients resident in the United States or Canada.
A closing note. A seed phrase that will not import is one of the most frightening things in self-custody, and the fear is what pushes people toward the website that promises a miracle and takes the wallet. The steadier truth is that the coins are still on the chain, the seed is usually intact information with a small recording error, and the mathematics — not a sales pitch — decides what is recoverable.
