[llifezou]

1. What is your project? (max 100 words)

Fil-wallet - A hierarchical deterministic wallet

https://github.com/llifezou/fil-wallet

https://github.com/llifezou/fil-sdk

https://github.com/llifezou/hdwallet

An open source, out-of-the-box hierarchical deterministic wallet tool

• One mnemonic can derive multiple addresses, which is convenient for users or storage providers to manage multiple private keys
• Hierarchical Deterministic protocol compatible with Filecoin secp256k1, bls

Solve problem:

• Convenience: the benefit of managing one mnemonic phrase without the need to manage multiple private keys
• Trust issue: open source wallet without any trust risk
• Reduced complexity: users do not need to start a Filecoin node, as long as they can have a node endpoint, such as Glif nodes, can send any transaction
• Extended: can even be used as an offline signature machine if necessary, with a large degree of security

2. How are you planning to improve this project? (max 200 words)

• Support offline signature
• Support signature verification
• Support balance inquiry
• Support transfer
• Support for send transactions
• Support multi-signature
• Support fvm calls (in the future)
