Frequently Asked Questions

Based on our extensive experience, we have developed proprietary software toolkits and optimized scripts (utilizing high-performance supercomputing systems on isolated hardware), enabling us to help you decrypt the correct wallet password.

File loss caused by operational errors has a very high data recovery success rate. Even if other operations were performed afterward, there is still an excellent chance to recover the wallet file.

If you forgot to backup the wallet.dat file saved on the hard drive (usually stored on C drive) and it was formatted during system reinstallation, although frequent hard drive operations reduce recovery probability, we have a professional data recovery laboratory that can attempt to help you recover the lost wallet file.

If your wallet is saved on a phone, computer, USB drive, cloud storage or other devices that are damaged, and you can no longer access the wallet due to hardware or software defects, we can help you retrieve the wallet through hardware repair.

When opening the wallet client, it prompts that the wallet.dat file is corrupted and backup rescue failed. This situation is mostly caused by virus damage or long-term storage hard disk sector damage and data loss. We will perform wallet repair or key extraction based on the degree of damage and encryption of your file.

This situation occurs because the transaction broadcast was unsuccessful. There are many reasons for this, such as: incomplete block synchronization, network connection problems, wallet internal code problems, etc. If you need to solve this problem, please contact us.

Mnemonic phrases have multiple algorithms. If you have transcription errors or incomplete records, you can contact us to help you calculate the correct mnemonic phrase.

Mnemonic phrases are the most convenient way to save cryptocurrencies, but many people find that the address recovered using the saved mnemonic phrase is wrong. This may be because you are using the wrong mnemonic phrase algorithm. If you need to solve this problem, please contact us.

Currently common mnemonic phrases are 12 or 24 words. 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23-word mnemonic phrases are relatively rare. They generally appear in various small wallets or protocol algorithms. If you encounter this problem, please contact us.

Our investigation experts will conduct detailed blockchain analysis to track fund flows and any connections to the real world. Once we have this information, we will teach you how to pursue recovery through law enforcement and relevant exchanges, providing you with as many recovery opportunities as possible.

For example: TRC20 USDT sent to ERC20 USDT address or ERC20 USDC sent to TRC20 USDC address, etc. We can usually recover funds sent to wrong address types, currently limited to stablecoins issued by centralized institutions.

Issues such as crashes, bricked devices, damaged buttons, broken screens, etc. In addition, we also provide PIN, mnemonic phrase and password recovery for hardware device wallets.

We can help you recover cryptocurrencies from damaged devices such as iPhone or Android. We have professional laboratories that can physically access the device.

Some software wallets were popular in the early days of Bitcoin but later became obscure and are no longer maintained. The first is the MultiBit Classic wallet, which only relies on passwords and was replaced by MultiBit HD, which also introduced mnemonic phrases. Many early Bitcoin adopters used such wallets on their computer hard drives.

Lost wallet transactions usually involve DeFi applications, sometimes related to failures or cross-chain/application incompatibilities. Be sure to document as much as possible about the lost transaction and then contact us.

This is especially common in DeFi transactions using wallets like Metamask and Trust Wallet, and can sometimes be reversed depending on the address type used and the blockchain involved. Accurately record what you did and then contact us.

This can happen during long periods of blockchain congestion or insufficient gas/miner fees to pay for the transaction. Another reason for pending, delayed or stuck transactions is that you entered an incorrect address or sent/received from a different blockchain.

BIP stands for Bitcoin Improvement Proposals, which are documents that propose new features or improvements for Bitcoin. They can be proposed by anyone and are published on bitcoin/bips after review. The relationship between BIP and Bitcoin is like RFC to the Internet.
Among them, BIP32, BIP39, and BIP44 together define the currently widely used HD Wallet, including its design motivation and concepts, implementation methods, examples, etc.
BIP32: Defines Hierarchical Deterministic wallet (abbreviated as "HD Wallet"), a system that can generate a tree structure from a single seed to store multiple sets of keypairs (private and public keys). The benefits are convenient backup, transfer to other compatible devices (because they all only need the seed), and hierarchical permission control, etc.
BIP39: Represents the seed with words that are convenient to remember and write. Generally composed of 12 words, called mnemonic code (phrase), Chinese called mnemonic words or mnemonic codes. For example: scrub river often kitten gentle nominee bubble toilet crystal just fee canoe
BIP44: Based on the BIP32 system, it gives special meaning to each layer in the tree structure. It allows the same seed to support multiple currencies, multiple accounts, etc. Each layer is defined as follows: m / purpose' / coin_type' / account' / change / address_index where purpose' is fixed at 44', representing the use of BIP44. And coin_type' is used to represent different currencies, for example, Bitcoin is 0', Ethereum is 60'.

Good question! If you send us your wallet and we crack the password, then we could steal the coins held by your wallet (we won't, but you can't be sure).
Fortunately, the developers of the official core wallet have designed it so that you only need to send us the encrypted password hash of the wallet private key. The hash you send us only allows us to decrypt the wallet without giving us any opportunity to steal money. Check various detailed explanations about Bitcoin wallet design (search Google). For more details, see the wallet page. (Please note that this only applies to some officially developed core wallets). For other wallets, before determining decryption, we will sign a legally guaranteed contract drafted by a professional legal team with you on-site to ensure the rights and interests of both parties before starting work.

Our pricing depends on the complexity of the recovery process. You can contact us at any time to get a quote tailored to your specific needs, usually ranging from 20-50% of the recovered wallet.
