Wonder Wallet

A self-custodial Bitcoin wallet for collectors. Your keys, your assets, and your data stay on your own device.

Wonder Wallet is a self-custodial Bitcoin wallet. Your keys, your assets, and your data stay on your own device — always. Built for collectors on Bitcoin, Wonder Wallet lets you hold your own keys and manage your Bitcoin, Ethereum, and Solana from a single recovery phrase, with first-class support for Bitcoin Stamps, SRC-20, and Counterparty assets. What you can do: • Hold your own keys — generated and encrypted in your browser, never sent anywhere. • View and manage your collection with full-resolution on-chain art. • Coin control that recognizes asset-bearing coins, so you don't spend a collectible by accident. • Send and receive Bitcoin, Ethereum, and Solana from one recovery phrase. • Works with Ledger hardware wallets over WebHID — your keys stay on the device and you approve each transaction. • Fee controls (replace-by-fee and child-pays-for-parent), customizable auto-lock, and dark or light themes. Security and privacy: • Keys are encrypted locally with Argon2id and AES-GCM and never leave your device. • All signing happens on your device. No accounts, no trackers, and no personal data collected. • No remotely hosted code — the extension runs under a strict Content-Security-Policy. Wonder Wallet is beta software, provided as-is. Please use a test wallet, not your life savings.
