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. – Don’t trust anyone with your savings. Copay wallets are similar to joint-checking accounts. You can have multiple users. To send money, the group approves each transaction. – Manage shared funds with friends and coworkers. Your child can have a wallet shared with you and introduce bitcoin to them. Copay makes it easy and secure to share a wallet. 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). When you send money to a Payment Protocol-enabled merchant, Copay securely verifies that your payment will go to the right place. TESTNET SUPPORT For Developers Copay has native support to the Bitcoin Testnet. This makes it easy for developers to test new bitcoin applications across different platforms. Copay makes it easy for developers to test, demo and deploy bitcoin applications. It supports multisignature (P2SH), multiple wallet support, and is a great way to get started. OPEN SUBSOURCE, NO EXCEPTIONS Copay is not only open-source, but the server as well. Enterprise and high-powered users can manage their finances in full control by deploying their own Copay apps or 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.
