In the past year, Phantom has experienced the fastest growth among web3 wallets, according to a February report by CoinMarketCap. The wallet has attracted more than 15 million active users, facilitating token swaps worth over $20 billion in 2024 alone. Phantom raised an additional $150 million at a $3 billion valuation in a Series C round…
