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. Like a joint-checking account, your Copay wallet can have multiple users. Each transaction must be approved by the group before it can be sent. – Manage your shared funds with coworkers or friends. To introduce bitcoin to your child, share a wallet. Copay makes sharing a wallet simple and secure. NO MORE TEDIOUS ADDRESS MANAGEMENT The Copay app securely stores multiple, distinct bitcoin wallets, allowing both business and privacy-conscious users to keep funds carefully 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 is the first bitcoin wallet to support the full Bitcoin Payment Protocol. (BIP 0070 – 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 for DEVELOPERS Copay provides native support for Bitcoin Testnet. This is ideal for testing new bitcoin apps across multiple platforms. Copay makes testing and demoing bitcoin applications easy with multisignature support (P2SH), and multiple wallet support. OPEN SOURCE. NO EXCEPTIONS. Not only is Copay’s app open source, but so is its server. 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 been developed by dozens and dozens of bitcoin developers. Every component of Copay is open for review and improvement by the community.
