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

We built the following features into this version of Copay for a bitcoin wallet that doesn't compromise on security or accessibility:
- Support Bitcoin and Bitcoin Cash
- 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

- Support for Bitcoin testnet wallets
- Customizable wallet naming and background colors
