Usage

Compatible with any dapp / smart contract. Simply copy & paste the ABI or artifacts.json for any deployed smart contract you would like to interact with.

1. Connect your wallet:

   Currently supported:
   - MetaMask
   - Custom RPC
   - Localhost
   

2. Add contract:

   - Paste the contract address in the "Contract" field
   - Click "Add Contract", you will then be prompted for the contracts ABI or Artifacts.json
   - You can copy any contracts ABI via most block explorers (is. etherscan.io, ftmscan.com, bscscan.com, etc.)
   - Alternatively, if this is a contract you deployed. You can copy & paste the artifacts.json
   - You will then be prompted to name the contract. This name is arbitrary. 
   - Finally, click "Add contract via ABI / Artifacts.json"
   

3. Functions:

   - Choose the contract from the contracts list (left sidebar)
   - The "Functions" list will then populate.
   - Choose from the list of smart contract function calls.
   - If the function is "view" you will "submit" (Free) otherwise "Pure" you will "Sign" and submit a txn (payable).
   - Returned values are logged in real time for easy visibility.
   

Custom gas limit, custom signer, and encoding are also supported!

CLI / Local Deployment:

Install

Compatible with any dapp / smart contract (Truffle, Buidler, etc.) as long as you provide the JSON artifacts. OR Manually add ABIs and or artifacts.json for pre deployed smart contracts.

1. Install from the command line:

   npm install @gweidart/[email protected]

   OR

   Install via package.json:

   "@gweidart/evm95": "1.0.0"

2. Run with path to your artifacts folder:

   @gweidart/evm95 ./build/contracts

3. Navigate to your Local Deployment via http://localhost:3000

4. Refer to steps 1 - 3 detailed at the beginning of this document in the Web App section.

How it works

When @gweidart/evm95 is run, an Express server is fired up and a frontend (packaged by Parcel) is served at localhost:3000 (you can define the port with the -p flag -p 1234). The server will watch the directory you passed in for any changes to your artifacts and send those changes to the frontend via Websockets.

Note: you can also add contracts manually if you have the ABI or Artifact (there is an Add Contract button).
