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. You can take security in your own hands and not trust third parties when it comes to your savings. Your Copay wallet can be used by multiple people, just like a joint-checking bank account. Each transaction must be approved by the group before it can be sent. – Manage shared funds with friends and coworkers. Share a wallet with your child and introduce them to bitcoin. Copay makes it simple and easy to share your wallet. COPAY APP DOES NOT REQUIRE TEDIOUS ADDRESS MAINTENANCE. Copay securely stores multiple bitcoin wallets. It allows both privacy-conscious and business users to keep their funds separated. 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 is the first bitcoin wallet to support the full Bitcoin Payment Protocol. (BIP 0070 – 0073). Copay verifies your payment when you send money to a Payment Protocol 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. Not only is Copay’s app open source, but so is its server. Enterprise and power users can take full control of their finances by deploying their own version of the Copay apps and Bitcore Wallet Service. Copay has been developed by dozens and dozens of bitcoin developers. Every part of Copay, wallet and server, is available to be reviewed, improved, and developed by the community.
