In the fast-evolving world of digital assets, decentralized applications, and the Web3 ecosystem, wallet extensions have become essential tools for securely interacting with blockchain networks. Among the most popular choices for users within the Solana ecosystem is Phantom Wallet. Known for its simplicity, speed, and highly polished user experience, Phantom has now extended its capabilities to Firefox through the “Phantom – Get this Extension for Firefox (en-US)” page on Mozilla Add-ons.

What is Phantom Wallet?
Phantom is a non-custodial crypto wallet designed primarily for the Solana blockchain, although recent updates have extended support to Ethereum, Polygon, and other emerging Layer-2 ecosystems.
