What is Copay? Copay works as a bitcoin wallet and not an account service. Secure your personal funds with multiple signatures, or just one. – Take security into your own hands and avoid trusting third parties with your savings. Copay wallets can have multiple users just like a joint check account. Each transaction must be approved by the group before it can be sent. – Share funds with coworkers and friends. Share a wallet with your child and introduce them to bitcoin. Copay makes sharing wallets easy 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. 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 is the first bitcoin wallet to support the full Bitcoin Payment Protocol. (BIP 0070 – 0073). Copay securely verifies the transaction when you send money via Payment Protocol to merchants. TESTNET SUPPORT TO DEVELOPERS Copay offers native support for Bitcoin Testnet. This allows you to test new bitcoin applications on multiple platforms. Copay’s multisignature and multiple wallet support makes it easy to develop and test bitcoin applications. OPEN SOURCE. NO EXCEPTIONS. Not only is Copay’s app open source, but so is its server. 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 has seen many contributions from bitcoin developers. And we’re not done yet. Every part of Copay, wallet and server, is available to be reviewed, improved, and developed by the community.
