Programmable Wallet Suite

Overview

Programmable Wallet Suite is a next-generation Bitcoin wallet available as a Chrome extension, desktop application, and command-line interface. Built for power users and developers who need advanced UTXO management, time-locks, and programmable transaction logic.

Unlike traditional wallets that hide complexity, Programmable Wallet exposes full control over UTXO selection, fee estimation, and transaction construction. Hardware wallet integration ensures private keys never touch the host system while maintaining advanced functionality.

Key Features

• Chrome Extension, Desktop & CLI: Unified wallet experience across browser, desktop app, and terminal with synchronized state.
• Hardware Wallet Support: Native integration with Ledger, Trezor, and Coldcard for secure key management.
• Advanced UTXO Coin Selection: Manual UTXO selection, coin control, and custom selection algorithms for privacy and fee optimization.
• Time-lock Contracts: Create and manage time-locked transactions using CLTV and CSV opcodes.
• Custom Transaction Scripting: Build complex spending conditions with Miniscript and custom Bitcoin Script.
