Phoenix Wallet, developed by ACINQ, is a self-custodial Lightning Bitcoin wallet with a strong emphasis on providing an intuitive user experience while maintaining the principles of non-custodial control. Available on both Android and iOS, Phoenix aims to make Lightning Network transactions as straightforward as traditional Bitcoin transactions, abstracting the complexities of channel management behind a clean, user-friendly interface. It operates by running a full Lightning node on your mobile device, ensuring that you have direct control over your funds, which is a significant feature for those who prioritize privacy and security.
Phoenix Wallet differentiates itself with features like automatic channel management, where it handles the creation, funding, and closing of channels without user intervention. This includes support for "trampoline payments," which simplify routing even when you're offline, enhancing the wallet’s usability. Additionally, Phoenix introduced "splicing," allowing for dynamic channel resizing, which means users can seamlessly manage their liquidity without needing to close and reopen channels. The wallet also supports BOLT12, providing reusable, non-expiring payment requests and contact lists for easier peer-to-peer transactions.
On the security front, Phoenix uses a 12-word recovery phrase for backups, standard in the crypto world, ensuring users can recover their funds if their device is lost or compromised. However, like all Lightning wallets, users must be cautious with backups, as losing the recovery phrase means losing access to funds. Phoenix is also open-source, which adds a layer of transparency and community trust, although it's worth noting that the app's dependency on ACINQ nodes for some operations can be seen as a potential centralization point.
