Frequently Asked Questions

No. The assessment is free and needs no sensitive material at all — a description is enough: which wallet, what happened, and what you still have. Under a written agreement we may later work with copies of wallet files on controlled systems, offline where appropriate, but never through a form, chat window or ordinary email. No legitimate service will ever ask you to type your recovery phrase into a website.

No, and treat any service that does with suspicion. What is possible depends entirely on what you still have. One missing BIP39 word creates a finite candidate set and the checksum narrows it, but the actual effort depends on the phrase, wallet type, any passphrase and what else is known. A phrase that is entirely gone, with no wallet file and no backup, cannot be rebuilt by anyone. After the free assessment you get a realistic estimate, never a promise, and you pay only if access is restored.

Dutch KvK registration 75927276, a physical office in Amsterdam, a named team, and a written agreement under Dutch law before any work begins. You can check the registration yourself in the Dutch business register. The team is small — fewer than ten people — so you speak directly with the person handling your case, and an NDA is available on request. The Trust Center sets out how to verify each of these independently.

We do not take stolen-crypto or scam cases. Once coins have been sent to someone else they sit in a wallet under their control, and no one can reverse a blockchain transaction. Report it to your local police and your national fraud authority, and keep the transaction IDs and addresses as evidence. Be careful with any service that contacts you afterwards promising to get the funds back for a fee; that is usually a second scam aimed at the same victim.

A wallet file, a device, a partial or complete recovery phrase, or a password you half remember are all material we can work from. Some incomplete, incorrectly ordered or invalid recovery phrases are solvable, but feasibility depends on how much reliable information remains and the size of the resulting search. What cannot be rebuilt is a phrase that is entirely gone with no wallet file, no backup and nothing remembered. That case is closed for us and for everyone else, and we will tell you so rather than take the work.

It depends on what we are working with. Simple password cases are often resolved in a few days. Complex passwords and partial recovery phrases take weeks, occasionally months, because the work means testing very large numbers of combinations systematically. Legacy formats can add time again, since the wallet software itself has to be reconstructed first. You receive a realistic estimate after the free assessment, before any work begins.

Before we accept a case we verify identity and proof of ownership through risk-based KYC and AML checks. For an inherited wallet that means the documents establishing your legal authority: a grant of probate, a certificate of inheritance, or an executor's appointment. We do not work on wallets that are not provably yours to access, and everything runs under a written agreement governed by Dutch law.

We are non-custodial: we do not receive, hold or move your assets on your behalf. Recovery work may require agreed, controlled access to sensitive wallet material, but the handover leaves you in control of the wallet and any asset movement. The fee is paid separately under the written agreement; it is not deducted from the wallet by us.

Yes. Cases can run entirely remotely over a secure connection, wherever you are; clients come to us from across Europe and America. You are also welcome at the Amsterdam office, and where travel allows we can come to you for the handover. The technical environment is selected for the case and uses offline processing where appropriate, so your location does not change the need for controlled handling.

The assessment is free. Our standard success fee is 20% of the recovered amount, agreed in writing before any work and due only once access is restored. There are no upfront charges and no hourly rates. For higher-value wallets the percentage is negotiable and is usually lower. You pay us directly at the handover; the fee never comes out of the recovered funds by our hand.

Yes. We work for heirs, executors, administrators, notaries and advisers once legal authority is established. What decides the case is the same as any other: whether a wallet file, a device, a backup or part of a recovery phrase still exists among the belongings. Old computers and phones are worth checking before anything is wiped or sold. We do not give legal or probate advice — that is your lawyer's work.

Recovery happens at the wallet level rather than the coin level, so the currency itself rarely decides the case. Our core expertise covers Bitcoin Core, Electrum, MultiBit, Blockchain.com, Ledger, Trezor, MetaMask and Jaxx Liberty, plus a long tail of legacy formats from the early 2010s. Describe the format and the material you still have; we will assess whether there is a technically realistic route.

Offline, on paper or stamped metal, in at least two separate physical locations. Never in a photo, a password manager, a cloud note or an email to yourself, and never typed into a website. Metal survives fire and water where paper does not. Write the words in order, note which wallet they belong to, and check the backup by restoring it once before you rely on it.

No. A public address lets anyone look up the balance, but spending requires the private key, the recovery phrase, or the password to an encrypted wallet file. Without one of those and without a backup, the wallet cannot be opened — not by us, not by the wallet's developers, and not by anyone else. Seeing the balance on a block explorer does not change that.

Age alone does not close a case. Your coins stay on the blockchain no matter how long the wallet has been unreachable, and discontinued software — MultiBit, Jaxx Liberty, old Bitcoin Core — does not change what is on chain. What matters is whether you still hold the wallet file, the key, or enough of the recovery phrase. Old formats may require the original environment or data structures to be reconstructed first, which can add time and is not always possible.

Usually not. A zero balance after a clean restore normally means one of two things: the wallet is looking at the wrong addresses, which is a derivation-path or address-type mismatch, or the phrase you restored is not the one that held the coins. Check one of your old receiving addresses on a block explorer. If the balance shows there, the coins are untouched and the problem is a settings issue that is usually straightforward to resolve.

You get a free assessment and an honest view of your chances and next steps. Before we accept a case we verify identity and proof of ownership. If you decide to go ahead we sign a written agreement, and work begins only after that, on copies where possible and on controlled systems, offline where appropriate. If the assessment shows the case cannot be done, we say so plainly and there is nothing to pay.
