Process & Fees

  1. 1

    Free Assessment

    Describe your situation via Telegram / Email (wallet type, how access was lost, any clues you remember). We respond with a feasibility assessment within a few business days — completely free.

  2. 2

    Service Agreement

    If recovery is feasible, we sign a service agreement specifying the fee (a success-based percentage of the recovered assets, depending on difficulty), confidentiality terms and the asset delivery method.

  3. 3

    Technical Recovery

    Depending on the case we apply computational password recovery, mnemonic repair or chip-level hardware recovery. Timelines range from days to months, with regular progress updates.

  4. 4

    Asset Delivery

    Recovered assets are transferred directly to a brand-new address you designate, verifiable on-chain end to end. After delivery we destroy all case data as agreed.

No recovery, no fee — you only ever pay after your assets are back.

FAQ

How do I know you won't run off with my assets?

Three safeguards: every case is covered by a formal service agreement; recovered assets are transferred directly to a brand-new address you designate, verifiable on-chain; and our track record is publicly verifiable, including the public confirmation and strategic investment by Liquid Capital founder Jack Yi.

How do you charge?

No recovery, no fee. On success we charge a percentage of the recovered asset value; the exact rate depends on difficulty and is written into the agreement before signing. No hidden costs.

Do I need to ship my hardware to you?

It depends on the case. Software-only cases (passwords, mnemonics, Keystore files) can be handled remotely. Physical cases such as hardware wallets or phones require shipping or an in-person handover — the exact arrangement is agreed during the free assessment.

How long does recovery take?

Simple password cases may take days; complex password derivation or chip-level recovery can take months or longer (for reference, the MultiBit case took about a year). We give you an estimated timeline during assessment and share progress regularly.

How is my data and privacy handled?

Case data is stored in isolation and accessible only to core technical staff. After the case closes, all related data is destroyed as agreed. See our Privacy Policy.

What cannot be recovered?

Mathematically irreversible situations: a mnemonic completely lost with no backup or clues, a private key overwritten or destroyed, etc. We tell you honestly during the free assessment and never take on hopeless cases.

Our Advantages

Asset recovery is a struggle with mathematics, time, cost, and human behavior; like any battle, tactics are constantly evolving.
