Phantom

Phantom started on Solana and is now a multichain wallet. Its Chrome listing names Solana, Ethereum and Polygon, with Ledger support for added security. It is self-custodial: Phantom says it never has access to your funds, and no name, email or phone number is needed to set it up.

The listing highlights scam detection that flags malicious transactions. Least Authority audited the wallet's mobile app and browser extension in a report dated 7 June 2024, with its suggestions resolved. Phantom also runs a bug bounty paying up to $50,000. It says other top firms have audited the code, with reports linked from its security page, but the page does not name them. In 2022 the "Demonic" flaw affected Phantom and other extension wallets; Phantom says fixes began rolling out in January 2022, and no exploitation was reported.

The trade-off is transparency. We did not find a public source repository for the extension, so you rely on audits and Phantom's word rather than reading the code yourself. The Firefox listing has not been updated since May 2025, so we link only the Chrome Web Store version. Best for Solana users and anyone who wants one wallet across several chains.
