Chui Wallet

Chui Wallet simplifies bitcoin payments with speed, precision, and ease.

Chui Wallet — bitcoin payments, built for merchants. Chui is a self-custody bitcoin wallet that runs as a Chrome extension. It was born from a simple need: a clean, business-friendly way to accept bitcoin without fighting your wallet. We focused on the two issues that frustrate business users and high-volume merchants the most. Why merchants choose Chui - One-click xPub connect. A standardised web-interface button to securely expose your extended public key to third-party services like Blockonomics. No more copy-pasting xPubs between tabs or config screens. - 200-address gap limit by default. Most wallets stop scanning after 20 unused addresses, which can hide funds on busy merchant wallets. Chui scans far deeper, with optimised discovery so performance stays fast even on long histories. - Non-custodial by design. Your seed phrase is encrypted locally and never leaves your browser. You hold the keys — always. Everything you'd expect from a modern bitcoin wallet - Native SegWit by default, with optional Taproot - Multiple wallets and accounts - Automatic unused-address generation, up to the gap limit - Three-tier fee estimation (fast / medium / slow) - Balances shown in BTC and your preferred fiat currency - Mainnet and testnet support - Wallet-connect support for sharing xPub on demand Built for trust Chui is built around best-practice Chrome extension security: minimal permissions, locally-encrypted secrets, password-gated access to sensitive data, and a small, auditable code surface. No accounts, no servers, no telemetry — just a wallet that works. Get paid in bitcoin. Keep your keys. Stay fast.
