Is Phantom safe?

Clean risk

Phantom is a non-custodial crypto wallet for Solana, Ethereum, Bitcoin, and Sui that injects provider APIs into web pages and sends session analytics to its own servers.

Phantom allows users to store, send, and receive cryptocurrency across multiple blockchains directly from the browser. It injects blockchain provider objects (window.phantom, window.solana, window.ethereum) into all web pages to enable dApp interactions. On each session start, the extension sends wallet account identifiers and address presence data to Phantom's analytics endpoint at data.phantom.app via RudderStack.

Where it sends data

Destinations our analysis observed Phantom contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • data.phantom.app

    Phantom sends data to data.phantom.app. No other extension we have analyzed sends data here.
