What is Copay? Copay acts as a real bitcoin wallet and not as an account service. Secure your personal funds with multiple signatures, or just one. – Take security into your own hands and avoid trusting third parties with your savings. Copay wallets can have multiple users just like a joint check account. Each transfer must be approved by the group to send money. – Manage shared funds with friends and coworkers. You can share a wallet and introduce your child to bitcoin. Copay makes sharing wallets easy and secure. COPAY OFFERS ONE-CLICK ADDRESS MANAGEMENT. The Copay app secures multiple bitcoin wallets. This allows business users and privacy-conscious individuals to keep their funds separate. Manage personal, business, and testnet wallets easily, all without leaving the app. Copay uses hierarchical-deterministic (HD) wallets, allowing for secure in-app wallet generation and backup. SECURE PAYMENT VIRIFICATION Copay has been the first bitcoin wallet that supports the full Bitcoin Payment Protocol (BIP0070–0073). Copay secures the payment to be sent to the correct place when money is sent to merchants that are Payment Protocol-enabled. TESTNET SUPPORT FOR DEVELOPERS Copay includes native support for the Bitcoin Testnet, perfect for testing new bitcoin applications across multiple platforms. Copay allows developers to easily test and demo new bitcoin applications using multiple wallet support and multisignature (P2SH). OPEN SOURCE – NO EXCEPTIONS. The Copay app and server are both open source. Enterprise and power users have the ability to take complete control of their finances and deploy their own versions of the Copay apps as well as Bitcore Wallet Service. Copay has already seen contributions from dozens of bitcoin developers, and we are not done yet. Each part of Copay, including the wallet and server are open to review, improvement, and development by the community.
