What is Copay? Copay works as a bitcoin wallet and not an account service. Secure your personal funds with multiple signatures, or just one. Secure your savings and take control of your security. Your Copay wallet can be used by multiple people, just like a joint-checking bank account. The group must approve each transfer before money can be sent. – Manage shared funds with friends and coworkers. Your child can have a wallet shared with you and introduce bitcoin to them. Copay makes sharing your wallet easy and secure. COPAY APP STORES SMALL, DIFFERENT BTC Wallets. This allows both business and privacy-conscious users the ability to securely store multiple wallets. 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 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’s multisignature and multiple wallet support makes it easy to develop and test bitcoin applications. OPEN SUBSOURCE, NO EXCEPTIONS Copay is not only open-source, but the server as well. Enterprise and power users have the ability to take complete control of their finances and deploy their own versions of the Copay apps as well as Bitcore Wallet Service. Copay has seen many contributions from bitcoin developers. And we’re not done yet. The community can review, improve, and develop every part of Copay (wallet and server).
