FCL: Flow Client Library

Making secure web applications powered by the Flow Blockchain

Flow Client Library (FCL) enables applications to easily integrate with all FCL-compatible wallets and other services (e.g. (Coming Soon) profiles, private information, notifications). This offers developers a strong foundation to compose their apps with existing building blocks. It’s currently supported for browser applications, and will be extended to other platforms.

With FCL, you can:

• Integrate all compatible wallets without any custom code or code injection
• Authenticate users
• Query the Flow Blockchain
• Send transactions (e.g. initializing resources, sending assets, purchasing, etc.)
• Sign transactions through wallet integration avoiding key management

With FCL, you will eventually be able to:

• Personally sign data via FCL Compatible Wallets
• Request Additional User info like Emails

Status

• Last Updated: Mar 2nd 2021

The things that exists probably won't be changing much externally, we will be adding new functionality in the near future.
