Symverse Web3 JavaScript SDK

It provides json rpc communication interface and development library with symverse blockchain, rpc api.

npm: https://www.npmjs.com/package/sym-web3js

Installation

Node.js

npm i sym-web3js

Yarn

yarn add sym-web3js

...

import SymWeb3 from "sym-web3js"

A minified, browserified file dist/sym-web3 is included for use in the browser. Including this file simply attaches the symjs object to window:

<script src='sym-web3.js'></script>

Usage

Use the symjs object directly from the global namespace:

console.log(SymWeb3)  // { utils: ...} 

const symjs = SymWeb3();
console.log(symjs); // {network: ..., utils: ..., signer: ...} 

Network connect

const symjs = SymWeb3();
symjs.network.connect("http://localhost:8001").then(connectedMessage => {
    console.log(connectedMessage, 'connect success...')
}).catch(e => {
    // connected fail...
})

There you go, now you can use it:

// Return Promise Object By Json RPC   
symjs.network.call.getBalance(address); 
symjs.network.call.clientVersion();

• Send Raw Transaction example:

let privateKey = "1a43aa399cb2efe186317e0b09f4a7ef88b83cff05089b145709881bf4db3a20"
let params = {
    from:"0x00021000000000010002",
    nonce: 210,
    gasLimit: 41000,
    to: "0x00021000000000020002",
    value: 5,
    workNodes: ["0x00021000000000010002"],
    chainId: 7777 //require
};
// Return Promise Object By Json RPC   
symjs.network.call.sendTransaction(params, privateKey);

• Citizen api call example:

// Return Promise Object By Json RPC   
let citizenInfo = await symjs.network.call.citizen.getCitizenBySymID("0x00021000000000010002")
let count = await symjs.network.call.citizen.getCitizenCount()

• Warrant api call example:

// Return Promise Object By Json RPC   
let blockNumber = await symjs.network.call.warrant.blockNumber()

• Sct api call example:

// Return Promise Object By Json RPC   
let constract = await symjs.network.call.sct.getContract("0x4523ad7875a9c41e9629")
let account = await symjs.network.call.sct.getContractAccount("0x4523ad7875a9c41e9629", "0x00021000000000010002")

Send Transaction Receipt confirmation

//send Transaction
const hash = await symjs.network.call.sendRawTransaction(symjs.signer.sign(params, pk))

// watch Transaction Receipt
const receipt = await watch(hash).next(symjs.network.call.getTransactionReceipt);

console.log(receipt)
