The cumulative crypto assets imBack has helped clients recover (valued at hundreds of millions of USD at current market prices):
Jack Yi is an early OG of China's crypto community and has invested in hundreds of blockchain projects since 2015. He owned an iPhone locked for 8 years that stored early-purchased BTC and wallet apps such as imToken, Bitpie and Kcash. imBack unlocked the device, recovered the BTC once thought lost forever, and earned Jack Yi's public endorsement and strategic investment.
The client stored BTC in a MultiBit wallet back in 2013 but forgot the password, leaving the assets dormant for 12 years (admittedly resulting in an accidental HODL).
Over drinks during the World Cup, the client set a 15- to 16-character imToken password and couldn't remember a thing the next day. The password bore almost no resemblance to any of the hints the client could provide.
A Japanese client's imToken 1.5 wallet had an issue. The client and a series of other technical teams worked on it for 8 years without success.
The client held crypto assets on a ColdLar hardware wallet that could no longer be accessed normally.
The client had installed TokenPocket on an iPhone 15 and held USDT in it, but forgot the transfer password. imBack once again demonstrated industry-leading capability and recovered all of the USDT in the wallet.
Years ago the client installed a wallet app via iOS TestFlight and created a BTC wallet. After the public release, the old TestFlight build crashed on launch, trapping the assets inside an app that could no longer be opened.
The above is only a selection of our cases. For more success stories, please contact us via Telegram @back_im — verification is welcome.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Asset recovery is a struggle with mathematics, time, cost, and human behavior; like any battle, tactics are constantly evolving.
