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 is approved by the group in order to send money. – Manage your shared funds with coworkers or friends. Share a wallet with your child and introduce them to bitcoin. Copay makes it easy and secure to share a 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. 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 – COPAY INCLUDES NATIVE SUPPORT FOR THE BTC Testnet. This support is perfect for testing new applications on different platforms. Copay allows developers to easily test and demo new bitcoin applications using multiple wallet support and multisignature (P2SH). OPEN SOURCE. NO EXCEPTIONS. Not only is Copay’s app open source, but so is its server. Enterprise and power users can fully control their finances with their own Copay apps and Bitcore Wallet Service. Copay already has the support of dozens upon dozens of developers. We are far from done. The community can review, improve, and develop every part of Copay (wallet and server).
