Configure FCL

Configure Blocto wallet to your Flow dApp

Installation

FCL is under heavy developments and the versions are not always backward compatible. We recommend that you use @blocto/fcl@^1.4.0 for now.

For why to use @blocto/fcl instead of @onflow/fcl, check out this Github PR for further information.

npm install @blocto/fcl@^1.4.0

yarn add @blocto/fcl@^1.4.0

pnpm install @blocto/fcl@^1.4.0
