Shared control over your money

This wallet requires every transaction to be authorized both by you and this third party. Under normal circumstances, you can regain full control over your bitcoins using your initial backup or pre-signed transactions sent by email.

Centralized validation

This wallet relies on a centralized service by default. This means a third party must be trusted to not hide or simulate payments.

Remote app

This wallet is loaded from a remote location. This means that whenever you use your wallet, you need to trust the developers not to steal or lose your bitcoins in an incident on their site. Using a browser extension or mobile app, if available, can reduce that risk.

Two-factor authentication

This wallet can be used from insecure environments. However, this service requires two-factor authentication. This means access to multiple devices or accounts is required to steal your bitcoins.

Basic privacy

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.

Discloses information to a third party

This service can associate your payments together, log your IP address and know your real identity if you provide personal information like your email, name or banking account.

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.

Full control over fees

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.

Before you start using Bitcoin for any serious transaction, be sure to read what you need to know and take appropriate steps to secure your wallet. Always remember that it is your responsibility to choose your wallet carefully and adopt good practices in order to protect your money.
