If your HD wallet is using Chinese or English mnemonic phrases and you’re unable to find your Bitcoin when restoring to another wallet, you can utilize this tool to convert the mnemonic phrase protocol and recover your Bitcoin. This issue typically arises because older wallets (such as BRD, also known as Breadwallet, and imToken) employ outdated protocols that newer wallets do not support. Don’t panic; your coins are still there.

Let’s begin by understanding the underlying principles:

In Bitcoin, BIP32, BIP44, BIP49, BIP84, and BIP141 are five related standards used for generating and managing wallet addresses. The main differences among these standards lie in how they derive child keys from a master key.

BIP32 is a standard for generating hierarchical deterministic wallets. It allows you to derive an unlimited number of child keys from a single master key, which can be used for different addresses and accounts. BIP32 employs a tree structure to organize these keys, with each child key having a unique identifier known as a “path.”

BIP44 is a standard for deriving specific types of addresses from a BIP32 master key. It defines standard paths for different cryptocurrencies, such as Bitcoin, Ethereum, and Litecoin. The BIP44 path format is:

1

m/44'/coin_type'/account'/change/address_index

where:

• m represents the “master key”
• 44' indicates “BIP44”
• coin_type' signifies the cryptocurrency type, e.g., 0' for Bitcoin
• account' indicates the account index, starting from 0
• change specifies the address type, with 0 for external addresses and 1 for internal addresses
• address_index is the address index, also starting from 0

BIP49 is a standard for deriving Segregated Witness (SegWit) addresses from a BIP32 master key. It is similar to BIP44, but it uses a different path to derive SegWit addresses. The BIP49 path is structured as follows:

1

m/49'/coin_type'/account'/change/address_index

BIP84 is a standard for deriving native SegWit addresses from a BIP32 master key. Similar to BIP49, it employs a different path to derive native SegWit addresses. The format for BIP84 paths is:

1

m/84'/coin_type'/account'/change/address_index

BIP141 is a standard that was established for the soft fork of Segregated Witness (SegWit). It activates SegWit and allows Bitcoin nodes to validate and accept SegWit transactions.

Here are the main differences among these standards:

Summary:

• BIP32 is a standard for generating hierarchical deterministic wallets.
• BIP44, BIP49, BIP84, and BIP141 are standards for deriving different types of addresses from a BIP32 master key.
• BIP141 is a standard for activating the SegWit soft fork.

Please Note:

• These standards are interrelated, but they can be used independently.
• You can choose to use mnemonic phrases to generate a BIP32 wallet.
• You can select BIP44, BIP49, BIP84, or BIP141 to derive addresses from a BIP32 master key.
