Wallet
This project is a multi-chain cryptocurrency wallet and self-custodial asset manager. It allows users to store, manage, and transfer digital assets across multiple blockchain networks while maintaining exclusive local control over private keys.
The application implements multisignature security, requiring a quorum of digital signatures from multiple participants to authorize transactions for shared funds. It also provides tools for self-custodial management, including hierarchical deterministic key derivation and local private key storage.
The platform covers a range of financial operations, including peer-to-peer asset transfers, digital asset swapping, and fiat-to-crypto onboarding via third-party integrations. Additional capabilities include blockchain portfolio tracking, currency pricing conversion, and transaction fee optimization.
Recovery and backup tools support the use of mnemonic seed phrases, encrypted backup files, and the sweeping of funds from paper wallets.
Features
