Key Manager v3.0

New in v3.0

🌱 BIP39 Derivation Engine
Derive addresses and private keys directly from 24-word mnemonics. Supports:

  • EVM (Ethereum / Arbitrum / Base) — m/44'/60'/0'/0/0
  • BTC Taproot (bc1p) — m/86'/0'/0'/0/0
  • BTC SegWit (bc1q) — m/84'/0'/0'/0/0
  • BTC Legacy (1...) — m/44'/0'/0'/0/0
  • SOL (Solana) — m/44'/501'/0'/0'
  • DASH (Dash) — m/44'/5'/0'/0/0
  • SUI (Sui) — m/44'/784'/0'/0'/0'

🔑 Enhanced Private Key Management
Private keys are now derived per-chain from your mnemonic, not stored as static entries. View individual chain keys or the master key. Each key is encrypted at rest and masked by default.
