AQUA
Non-custodial Bitcoin, Lightning, and Liquid mobile wallet. Open source, atomic swaps, global financial inclusion focus. iOS and Android.
AQUA is an open-source, non-custodial mobile Bitcoin wallet developed by Jan3, designed with a focus on global financial inclusion — particularly in Latin America and regions with limited banking access. It supports Bitcoin on-chain, Lightning Network, Liquid Network, and Tether USDt in a unified interface, with non-custodial atomic swaps between networks using Boltz. Features include Replace-By-Fee (RBF) support, low-fee international transfers, in-app Bitcoin purchasing, and a prepaid Dolphin Card for day-to-day spending. AQUA is particularly suited to users who need stable value storage alongside Bitcoin. Note: AQUA is not Bitcoin-only — it supports Liquid assets including Tether USDt. Open source on GitHub (AquaWallet/aqua-wallet). Available on iOS and Android.
