One year ago, we set out to build a bitcoin wallet secure enough for our company's funds. After a year of beta testing and use, we're releasing the first version of Copay.
Hold bitcoin, not IOUs.
When you use Copay, you control your money. Simple, secure, future-proof backups mean you'll always have access to your bitcoin, no bank required. And without a middleman holding your money, the next hacked company won't cost you your savings.
Multiple wallets, one app.
The Copay app securely stores multiple, distinct bitcoin wallets, allowing both business and privacy-conscious users to keep funds carefully separated, without tedious address management.
Both shared and personal wallets.
Copay provides a convenient flow for sending funds from shared wallets, requiring approval of multiple people – perfect for company and group wallets. Copay personal wallets also make routine payments simple.
Open Source. All of it.
We're serious about security and privacy. Not only is the Copay app open source, the server is too. Enterprise and power users can take full control of their finances by deploying their own version of the Copay apps and Bitcore Wallet Service. Of course, all users can use BitPay's official apps and service, no additional setup required.
Available on all your devices.
The Copay app is available on iOS, Android, Windows Phone, Chrome extension, Mac OS X, Windows, Linux, and universal Node-powered CLI. Download it from the Google, Windows, and Apple app stores or from Copay.io.
Testnet support for developers.
Copay includes native support for the Bitcoin Testnet, perfect for testing new bitcoin applications across multiple platforms. With multisig (P2SH) and multiple wallet support, Copay makes it simple for developers to test and demo bitcoin applications without fumbling between other mobile apps.
Better and better.
Dozens of bitcoin developers have already contributed to Copay, and we're not finished yet. Every part of Copay, wallet and server, is available to be forked, changed, and developed by the community. You can follow along, discuss improvements, and join in on GitHub at bitpay/copay and bitpay/bitcore-wallet-service.
