Armory is an advanced Bitcoin client that expands its features for Bitcoin power users. It offers many backup and encryption features, and it allows secure cold-storage on offline computers.
This wallet gives you full control over your bitcoins. This means no third party can freeze or lose your funds. You are however still responsible for securing and backing up your wallet.
This wallet requires you to install full node software that validates and relays transactions on the Bitcoin network. This means no trust in a third party is required when verifying payments. Full nodes provide the highest level of security and are essential to protecting the network. However, they require more space (over 145GB), bandwidth, and a longer initial synchronization time.
The developers of this wallet publish the source code for the client. This means any developer in the world can audit the code. However, you still need to trust developers of this wallet when installing or updating the final software because it was not built deterministically like Bitcoin Core.
Prevents spying on your payments
This wallet makes it harder to spy on your balance and payments by rotating addresses. You should still take care to use a new Bitcoin address each time you request payment.
Avoids disclosing information
This wallet does not disclose information to peers on the network when receiving or sending a payment.
Tor can be used
This wallet lets you setup and use Tor as a proxy to prevent attackers or Internet service providers from associating your payments with your IP address.
This wallet gives you full control over fees. This means that this wallet allows changing the fees after funds are sent using RBF or CPFP. This wallet also provides fee suggestions based on current network conditions so that your transactions are confirmed in a timely manner without paying more than you have to.
