What is Copay? Copay acts as a real bitcoin wallet and not as an account service. You can secure your personal funds using multiple signatures or one. – Secure your personal savings by taking control and trusting only yourself. Like a joint-checking account, your Copay wallet can have multiple users. The group must approve each transfer before money can be sent. – Manage shared money with friends or 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. You can manage your personal, business and testnet wallets all from the same app. Copay uses hierarchical-deterministic (HD) wallets, allowing for secure in-app wallet generation and backup. SECURE VERIFICATION OF PAYMENTS Copay was one of the first wallets to accept the full Bitcoin Payment Protocol. Copay secures your money when you send it to a Payment Protocol-enabled merchant. TESTNET SUPPORT FOR DEVELOPERS Copay includes native support for the Bitcoin Testnet, perfect for testing new bitcoin applications across multiple platforms. Copay makes testing and demoing bitcoin applications easy with multisignature support (P2SH), and multiple wallet support. OPEN SOURCE – NO EXCEPTIONS. The Copay app and server are both open source. Enterprise and high-powered users can manage their finances in full control by deploying their own Copay apps or Bitcore Wallet Service. Copay already has the support of dozens upon dozens of developers. We are far from done. Each part of Copay, including the wallet and server are open to review, improvement, and development by the community.
