What’s Copay? Copay can be described as a genuine bitcoin wallet. It is not an account-service. Secure your personal funds with multiple signatures, or just one. Secure your savings and take control of your security. Copay wallets are similar to joint-checking accounts. You can have multiple users. To send money, the group approves each transaction. – Share funds with coworkers and friends. Share a wallet with your child and introduce them to bitcoin. Copay makes sharing your wallet easy and secure. COPAY APP SAVES YOU TIME AND OFFERS A RANDOM SYSTEM FOR ADDRESS MANAGEMENT. Copay secures multiple wallets for bitcoin, so business and private users can keep their money separate. Access your testnet, business, personal and business wallets from within the app. Copay uses hierarchical-deterministic (HD) wallets, allowing for secure in-app wallet generation and backup. SECURE PAYMENT VIRIFICATION Copay was the first to support the full Bitcoin Payment Protocol (BIP0070-0073). 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. With multisignature (P2SH) and multiple wallet support, Copay makes it simple for developers to test and demo bitcoin applications without fumbling between other mobile apps. OPEN SOURCE. NO EXCEPTIONS. Not only is Copay’s app open source, but so is its server. Enterprise and powerful users can have full control over their finances by deploying their version of the Copay app and Bitcore Wallet Service. Copay has already seen contributions from dozens of bitcoin developers, and we are not done yet. Every aspect of Copay, server and wallet, can be reviewed and improved by the community.
