Neon-DappKit

Neon-DappKit is the easiest way to build a dApp on Neo3. Suitable to connect Web Applications, Off-chain JS Servers and React-Native Apps to the Neo3 Blockchain.

WalletConnectSDK uses Neon-DappKit Types, so you can easily swap between Neon-DappKit implementation and WalletConnectSDK on the fly and reuse code, check the guide.

Installation

npm i @CityOfZion/neon-dappkit

In the vite.config.ts file you must change the global value like this:

export default defineConfig({
    //your config here
	define: {
		global: 'globalThis',
        //...
	},
});

Getting Started

Neon-Dappkit has 4 main components:

• NeonInvoker: SmartContract Invocation Tool.
• NeonParser: Powerful Parser for Neo3 Types.
• NeonSigner: Signs, Verifies, Encrypts and Decrypts data.
• NeonEventListener: Listen to events from the Neo3 Blockchain.

Quick Example

import { NeonInvoker, NeonParser } from "@CityOfZion/neon-dappkit";

const invoker = await NeonInvoker.init({
    rpcAddress: NeonInvoker.TESTNET,
})

const rawResp = await invoker.testInvoke({
    invocations: [
        {
            scriptHash: '0x123456',
            operation: 'myMethod',
            args: [123, 'Test'].map(NeonParser.formatRpcArgument)
        },
    ],
})

const resp = NeonParser.parseRpcResponse(rawResp.stack[0])
