Our take
Cryptocurrency wallets provide a way to protect secret information that gives users control over your digital assets. Many crypto enthusiasts prefer the wallet option as non-custodial wallets remove the third-party option and users gain full control over their data. Phantom is a cryptocurrency wallet that creates a space for users to buy, send, receive, swap tokens and collect NFTs.
Phantom hosts the Solana blockchain, though Ethereum is generally more popular within the crypto world, Solana is said to have faster speeds and lower transaction costs. Offering the same wallet features as its competitors, the company is setting itself apart with newer features like the “Burn NFTs” feature allowing users to remove spam NFTs sent by attackers and support them in dodging NFT theft prevalent in the sector. The company prides itself on extremely high-security factors.
Founded in 2021, the company has an impressive firm valuation of $3B and has earned its place as a top-rated crypto wallet. As the crypto space continues to evolve, Phantom is positioning itself not just as a wallet, but as a comprehensive platform for managing the full range of digital assets and decentralized applications.
