Secure bitcoin on your own terms with an open source, multisignature wallet from BitPay.
Copay users can hold funds individually or share finances securely with other users with multisignature wallets, which prevent unauthorized payments by requiring multiple approvals. Here are some ways Copay can be used with others:
To save for vacations or joint purchases with friends
To track family spending and allowances
To manage business, club, or organization funds and expenses
We built the following features into this version of Copay for a bitcoin wallet that doesn't compromise on security or accessibility:
Multiple bitcoin wallet creation and management in-app
Integration for buying and selling bitcoin.
Integration for buying Amazon.com gift cards.
Intuitive multisignature security for personal or shared wallets
Device-based security: all private keys are stored locally, not in the cloud
Hierarchical deterministic (HD) address generation and wallet backups
Payment protocol (BIP70-BIP73) support: easily-identifiable payment requests and verifiably secure bitcoin payments
Support for 150+ currency pricing options and unit denomination in BTC or bits
Email and push notifications for payments and transfers
Easy spending proposal flow for shared wallets and group payments
Support for Bitcoin testnet wallets
Customizable wallet naming and background colors
Multiple supported languages, including French, German, Chinese (Simplified), and Spanish
Copay is free and open source software run on non-proprietary servers, so there's no need to rely on any company for continuous support. Anyone can review or contribute to Copay's source code on GitHub (https://github.com/bitpay/copay).
