aelf-smartcontract-viewer

The aelf-smartcontract-viewer is a React component that provides an easy interface to view and interact with smart contracts on the Aelf blockchain. You can use this component to input contract details and view available read and write methods. This tool is useful for developers building applications around Aelf smart contracts, allowing easy testing and interaction with deployed contracts.

Installation

You can install the package using npm:

1npm install aelf-smartcontract-viewer

Usage

Basic Example

1import React from "react";
2import { ContractView } from "aelf-smartcontract-viewer";
3
4const App = () => {
5  return (
6    <div>
7      <ContractView
8        address="your_smart_contract_address"
9        rpcUrl="rpc_url" // i.e = https://explorer-test-side02.aelf.io/chain
10        contractName="Smart Contract Name"
11      />
12    </div>
13  );
14};
15
16export default App;

Props

Prop	Type	Default	Description
wallet	IWalletInfo	undefined	Optional wallet info. If not provided, a new wallet is generated.
headerTitle	string	"Aelf Contract View"	Title for the contract view header.
headerShown	boolean	true	Whether the header should be shown or not.
address	string	undefined	Address of the contract. If not provided, a default contract address is fetched from the Aelf blockchain.
contractName	string	"Contract"	The name of the contract to be displayed.
rpcUrl	string	"https://explorer-test-side02.aelf.io/chain"	The RPC URL to connect to the Aelf blockchain.
theme	light or dark	"light"	Theme of contract view component

Example Explanation

The above example demonstrates how to use the ContractView component. You only need to pass in the contract's address, RPC URL, and optionally the contract name.

Smart Contract Interaction

The ContractView component displays the available read and write methods from the given smart contract. Once loaded, the methods are grouped as follows:

• Read Methods: These are functions you can call to read data from the contract without sending a transaction.
• Write Methods: These are functions that will initiate a blockchain transaction to update the state of the contract.

Example with Wallet

If you want to specify your own wallet, you can pass the wallet prop. If you don’t provide a wallet, the component will create a new wallet for you and interact with the blockchain using that.

1import React from "react";
2import { ContractView } from "aelf-smartcontract-viewer";
3import AElf from "aelf-sdk";
4
5const App = () => {
6  const wallet = AElf.wallet.getWalletByPrivateKey("YOUR_PRIVATE_KEY");
7
8  return (
9    <div>
10      <ContractView
11        wallet={wallet}
12        address="your_smart_contract_address"
13        rpcUrl="rpc_url" // i.e = https://explorer-test-side02.aelf.io/chain
14        contractName="Smart Contract Name"
15      />
16    </div>
17  );
18}
19
20export default App;

Features

• Auto Wallet Creation: If no wallet is provided, the component creates a new wallet.
• RPC URL Management: Users can select different RPC URLs for connecting to different blockchain networks.
• Contract Method Interaction: The component lists both read and write methods available on the contract, allowing for easy interaction.
