Mycelium Bitcoin Wallet

Mycelium Wallet is a security-first, feature-rich app for managing Bitcoin (BTC), Ethereum (ETH), and ERC-20 tokens. It’s built to support both beginners and advanced users who want full control over their funds. Available on Android (including installation via APK) and iOS.

Key Features

• Seed-based backup (BIP39): uses a master seed so you can create a backup once and keep it safe for the long term.
• Control across devices: manage your wallet on multiple devices without surrendering ownership.



• Privacy with super nodes: connect using a Tor hidden-service (.onion address) to improve privacy and availability.
• Adaptive transaction fees: dynamic fee handling helps ensure your transactions are processed in a timely way based on current network conditions.
• Fee/byte visibility: transaction details display fee-per-byte so you can estimate execution time.
• Watch-only addresses: support for single-key or HD watch-only setups for secure cold-storage workflows.
• Private key import: import a single private key or an xPriv.
• Spend from paper wallets: send funds directly from paper wallets using a single key, xPriv, or a master seed.
• Hardware wallet spending (direct support):
  • Trezor
  • Ledger (Nano, Nano-S, Unplugged, HW.1, Trustlet)
  • KeepKey

• Compact QR codes (BIP73): uses more compact QR code formats for easier handling.

Why People Like It

• Secure HD wallet design: Mycelium is an HD (Hierarchical Deterministic) wallet that generates a fresh address each time you send or receive. That makes it harder for others to track your balance and activity. HD also simplifies backup and restore of Bitcoin addresses. For additional protection, use a trusted password manager, enable two-factor authentication, and consider encrypted messaging/email when communicating.



• Separate accounts: manage multiple accounts—for example, keeping different expenses under different accounts.
• Built-in exchange support: handles exchange rates for 164 currencies, letting you send and receive using current rates.
• Pair with hardware wallets: connect for stronger security using devices such as Trezor and Ledger.
