Wallet Recovery Service — Self Custody Bitcoin Wallet

How it works

Four steps. No surprises.

You tell us the situation

Fill the questionnaire below. Every answer narrows the search space — even fragments help.

We assess feasibility

Free technical assessment: we estimate the search space and give you a candid probability. No hype.

NDA & scope, then compute

We sign your NDA, agree the written scope, and commit our own compute at our own cost.

Recovery or zero bill

Success: you pay 35% of recovered funds. Failure: you pay nothing. Ever.

What we recover

Wallets we work with.

If your wallet type isn't listed, ask — the underlying cryptography is usually the same.

⚠ Randstorm-era wallets: JavaScript wallets created between 2011 and 2015 — Blockchain.info, Dogechain.info, early web-based Litecoin wallets, and many others — were generated with a browser RNG that made their keys far weaker than intended. If your wallet dates from that window, recovery can be realistic even with a forgotten password, because the key space itself was flawed. Tell us the creation date — it changes everything.

Pricing

Only success costs anything.

If we recover your access

35%

of the recovered funds — our entire fee. No retainers, no hourly billing, no expense charges. Everything else is yours.

If we fail

You owe nothing. Not a dime — no "attempt fees", no consulting charges, no costs passed on. Risk is entirely ours.

Start your case

Recovery intake questionnaire.

Answer as much as you can — partial answers still help. Send only what you consider safe: never send us your seed phrase, private keys, or wallet files through this form.

// 1 · About you

Full name *

Required.

Email *

Valid email required.

Telegram (optional)

Country of residence *

Required.

// 2 · The wallet

Wallet type *

Approximate year of creation *

Required.

Exact (or closest) creation date? *

Day/month if known — for web wallets of the 2011–2015 era this can be decisive.

Required — even an approximate window helps.

Browser / device used to create it?

For web wallets: the browser's RNG is part of the story.

What OS was it used on? *

Do you still possess the wallet file / paper? *

Be precise — the file (or its absence) defines which recovery routes exist.

Public address / Wallet ID (optional)

A PUBLIC address only — never a private key. First/last characters suffice for us to confirm the target.

What exactly do you still have? *

List materials — but do NOT paste actual keys, seeds or files here.

Required.

Have you (or others) already attempted recovery?

Prior attempts and tools tried change our strategy — tell us honestly.

// 3 · The passphrase

Roughly how long was it? *

Any fragments you remember? *

Fragments, themes, language, names, dates — anything. Don't guess wrong on purpose; estimates are fine.

Required.

Character types used?

Keyboard layout back then?

Your password style in that era?

Patterns from old accounts you still remember are gold.

// 4 · Terms

I understand the fee is 35% of recovered funds, success-only, and $0 if recovery fails. I confirm I have NOT included any seed phrases, private keys, or wallet files in this form. I agree that this inquiry is a request for a feasibility assessment, not a guarantee of recovery, and consent to being contacted about this case.
