Description

Secure bitcoin on your own terms with an open source, multisignature wallet from BitPay.

Copay users can hold funds individually or share finances securely with other users with multisignature wallets, which prevent unauthorized payments by requiring multiple approvals. Here are some ways Copay can be used with others:

To save for vacations or joint purchases with friends
To track family spending and allowances
To manage business, club, or organization funds and expenses

We built the following features into this version of Copay for a bitcoin wallet that doesn't compromise on security or accessibility:

Multiple wallet creation and management in-app
Intuitive multisignature security for personal or shared wallets
Easy spending proposal flow for shared wallets and group payments
Hierarchical deterministic (HD) address generation and wallet backups
Device-based security: all private keys are stored locally, not in the cloud
Support for Bitcoin testnet wallets
Synchronous access across all major mobile and desktop platforms
Payment protocol (BIP70-BIP73) support: easily-identifiable payment requests and verifiably secure bitcoin payments
Support for 150+ currency pricing options and unit denomination in BTC or bits
Email notifications for payments and transfers
Customizable wallet naming and background colors
4 supported languages (EN, JP, FR, ES)

Copay is free and open source software run on non-proprietary servers, so there's no need to rely on any company for continuous support. Anyone can review or contribute to Copay's source code on GitHub (https://github.com/bitpay/copay).

Customer Reviews

Great Full-featured Wallet App

Just wanted to say I've tried several wallet apps over the last few months and Copay's is the best I've found It has features other wallets just don't have like the ability to adjust your transaction fees, a list of used addresses and how much bitcoin is associated "on" each one, the ability to create several other separate wallets inside, color schemes, naming and password protection, links to your transaction on the Blockchain databases, etc. Give it a try!

Available on tons of platforms

I use shared wallets across several phones and laptops. For my spending wallet, only one signature is required. For more security, I use a separate savings wallet which requires all signatures. Copay makes this setup incredibly easy to use. Love it!

Best HD wallet

Simple, supports multiple wallets, has all the features.

It also supports BIP 44 and BIP 32. And I'm looking forward to see them including BIP 47 support.

It is also available on all platforms through Cordova and other open standards.

App is Open Source and it connects directly to the Blockchain network. Private key is kept in the app, not in a web service.
