What is Copay? Copay works as a bitcoin wallet and not an account service. Secure your personal funds with multiple signatures, or just one. – Don’t trust anyone with your savings. Copay wallets can be shared with multiple users, much like a joint checking account. 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 it simple and easy to share your wallet. COPAY APP STORES SMALL, DIFFERENT BTC Wallets. This allows both business and privacy-conscious users the ability to securely store multiple wallets. All your wallets can be managed easily from the app, including testnet, business and personal. 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 SUBSOURCE, NO EXCEPTIONS Copay is not only open-source, but the server as well. 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 already has the support of dozens upon dozens of developers. We are far from done. Every aspect of Copay, server and wallet, can be reviewed and improved by the community.
