# Multichain SDK

We plan to unify various SDKs/ APIs of blockchains in this library following the structure of `ethers.js` and provide a multichain SDK for cross-chain application development. IParticularly, we simplify the management process of smart contracts by integrating common operations, enabling the minting, transferring, etc., of NFT with low code.

**Currently Supported Blockchain**

- [x] Ethereum (Based on `ethers.js`)
- [x] Conflux  (Based on `js-conflux-sdk.js`)

### Basic Structure

```
Unified Chain" SDK
{
    providers: {
        BaseProvider,
        Web3Provider,
        JsonRpcProvider
    },
    Signer,
    VoidSigner,
    Wallet,
    Contract
    ContractFactory,
    ContractClient
}
```

## Installation

```shell
npm install
```

## Quick Start


### Run an example of the NFT Kit
```
npx ts-node main.ts
```


### Simple Example
```typescript
import { createMultichainSDK } from "./multichain";

const cfx_sdk = createMultichainSDK("Conflux")
const eth_sdk = createMultichainSDK("Ethereum")

// provider (JsonRpcProvider/ Web3Provider)
cfx_privider = new cfx_sdk.providers.Web3Provider(windows.conflux);
eth_privider = new eth_sdk.providers.Web3Provider(windows.ethereum);


// signer (JsonRpcSigner/ Wallet)

cfx_signer = cfx_privider.getSigner();
eth_signer = eth_privider.getSigner();

cfx_PK = "******"
eth_PK = "******"

cfx_wallet = new cfx_sdk.Wallet(cfx_PK, cfx_privider);
eth_wallet = new eth_sdk.Wallet(eth_PK, eth_privider);

// contract
cfx_abi, cfx_adress = "*", "*"
eth_abi, eth_adress = "*", "*"

cfx_contract = new cfx_sdk.Contract(cfx_adress, cfx_abi, cfx_signer)
eth_contract = new eth_sdk.Contract(eth_adress, eth_abi, eth_signer)
```
