The Flow Dev Wallet is a mock Flow wallet that simulates the protocols used by FCL to interact with the Flow blockchain on behalf of simulated user accounts.
_10This project implements an FCL compatible_10interface, but should **not** be used as a reference for_10building a production grade wallet._10_10This project should only be used in aid of local_10development against a locally run instance of the Flow_10blockchain like the Flow emulator, and should never be used in_10conjunction with Flow Mainnet, Testnet, Canarynet or any_10other instances of Flow.
Before using the dev wallet, you'll need to start the Flow emulator.
The Flow emulator is bundles with the Flow CLI. Instructions for installing the CLI can be found here: flow-cli/install/
Run this command to create
flow.json file (typically in your project's root directory):
Start the emulator
Start the emulator and deploy the contracts by running the following command from the directory containing
flow.json in your project:
_10flow emulator start_10flow project deploy --network emulator
The Flow Dev Wallet is designed to be used with
1.0.0 or higher. The FCL package can be installed with:
npm install @onflow/fcl or
yarn add @onflow/fcl.
To use the dev wallet, configure FCL to point to the address of a locally running Flow emulator and the dev wallet endpoint.
_10import * as fcl from "@onflow/fcl"_10_10fcl_10.config()_10// Point App at Emulator REST API_10.put("accessNode.api", "http://localhost:8888")_10// Point FCL at dev-wallet (default port)_10.put("discovery.wallet", "http://localhost:8701/fcl/authn")
It's easy to use this FCL harness app as a barebones app to interact with the dev-wallet during development:
Navigate to http://localhost:8701/harness
Releasing a new version of Dev Wallet is as simple as tagging and creating a release, a Github Action will then build a bundle of the Dev Wallet that can be used in other tools (such as CLI). If the update of the Dev Wallet is required in the CLI, a seperate update PR on the CLI should be created.
