Privacy Protection

Keep your financial information private and secure

Your Privacy Matters

Multibit Wallet is designed with privacy at its core. Unlike web wallets or lightweight clients that leak your addresses to third-party servers, Multibit gives you complete control over your financial privacy.

As a full validation node, Multibit downloads the entire blockchain locally. This means you never need to ask external servers which transactions belong to you, preventing anyone from linking your Bitcoin addresses to your IP address or identity.

Threat Model

How Multibit protects your financial privacy

Blockchain Analytics & Tracking Services

Many wallets leak address queries to third-party servers. Multibit validates locally, so your addresses aren’t sent out for lookup, reducing the chance of being profiled by analytics companies.

Malicious or Compromised Servers

There are no required accounts or backend services that hold your data. With no central server to trust, there’s no single point where user information can be harvested.

Targeted Attacks on End Users

Keys never leave your device, and signing happens locally. Even if someone monitors the network, they can’t extract private keys or reconstruct your wallet activity.

Data Seizure & Forced Disclosure Scenarios

Because Multibit doesn’t store user data remotely, there’s nothing meaningful to obtain from service providers. What exists stays under your control on your machine.

Privacy Best Practices

Additional steps to maximize your privacy

Store your recovery phrase physically

Write your seed phrase on paper or metal and keep it offline. Do not store it in cloud drives, screenshots, messengers, or note apps. Anything connected to the internet can leak, even if it feels private.

Never share your seed phrase

No wallet, no developer, no support team will ever need it. If someone asks for your recovery phrase, they are trying to steal your funds. There are no exceptions to this rule.

Always verify your wallet software

Download Multibit only from the official website. Be careful with links from ads, forums, or social media. Fake wallets look real and exist only to steal keys.

Be discreet about Bitcoin online

Avoid talking publicly about your balances, addresses, or setup. The less people know you hold Bitcoin, the harder it is for anyone to target you socially or technically.

Keep your device clean and up to date

Use system updates, avoid pirated software, and don’t install random tools on the same machine where your wallet lives. Most wallet compromises start with a compromised device.

Think about physical access

Lock your computer when you’re away. Keep backups hidden. Assume that anyone who can touch your device or your notes could become a threat, even if they don’t look like one.

Important Privacy Notice

Bitcoin transactions are permanently recorded on the public blockchain. While Multibit is built to reduce unnecessary data sharing, using Bitcoin is never fully anonymous by default. It is important to think about privacy before every transaction.

If you need a higher level of privacy, consider using techniques like CoinJoin or other tools designed to limit transaction tracing. For cases where full anonymity is required, research options carefully and understand the trade-offs before using any alternative solutions.

Use Bitcoin with privacy in mind

Multibit helps reduce how much of your activity is shared by default. Install the desktop wallet and take a more careful approach to using Bitcoin.
