I built a multichain wallet SDK that abstracts key management and transaction signing across multiple blockchain virtual machines (EVM & non-EVM) using a single HD wallet seed.
The goal is to make it easy for developers to integrate wallet functionality without dealing with chain-specific complexity.
What it does
Generates HD wallets (BIP32/BIP39) from a single mnemonic
Derives and manages addresses across multiple chains
Provides a unified interface for:
Key management
Transaction signing
Chain-specific wallet logic
