What’s Copay? Copay can be described as a genuine bitcoin wallet. It is not an account-service. You can either use multiple signatures to protect your personal funds or just one. Secure your savings and take control of your security. Copay wallets can be shared with multiple users, much like a joint checking account. The group must approve each transfer before money can be sent. – Share funds with coworkers and friends. Your child can have a wallet shared with you and introduce bitcoin to them. Copay makes sharing a wallet simple and secure. 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. The app allows you to manage personal, business, or testnet wallets quickly and easily. 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 TO DEVELOPERS Copay offers native support for Bitcoin Testnet. This allows you to test new bitcoin applications on multiple 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. Dozens of bitcoin developers have already contributed to Copay, and we're not finished yet. Every aspect of Copay, server and wallet, can be reviewed and improved by the community.
