How to use local binance smart chain lightclient to access the blockchain with web3 js

0 votes

I have downloaded and launched the light client node.

./lightd --chain-id "Binance-Chain-Tigris" --node tcp://dataseed1.binance.org:80 I[2021-03-25|03:19:19.040] Connecting to source HTTP client... I[2021-03-25|03:19:19.041] Constructing Verifier... I[2021-03-25|03:19:19.041] lite/proxy/NewVerifier()... module=lite/proxy chainID=Binance-Chain-Tigris rootDir=.binance-lite client=WSEvents I[2021-03-25|03:19:19.098] DBProvider.LatestFullCommit()... module=lite label=trusted.mem chainID=Binance-Chain-Tigris minHeight=1 maxHeight=9223372036854775807 I[2021-03-25|03:19:19.098] DBProvider.LatestFullCommit()... module=lite label=trusted.lvl chainID=Binance-Chain-Tigris minHeight=1 maxHeight=9223372036854775807 I[2021-03-25|03:19:19.099] DBProvider.LatestFullCommit() found latest. module=lite label=trusted.lvl height=1 I[2021-03-25|03:19:19.100] Starting proxy... I[2021-03-25|03:19:19.697] Starting RPC HTTP server on 127.0.0.1:27147



I can see that the proxy is started. I use the following line of code to set up the web3:-

WSS_URL=tcp://0.0.0.0:27147/websocket HTTPS_URL=http://0.0.0.0:27147
const httpsUrl = process.env.HTTPS_URL const wssUrl = process.env.WSS_URL const jsonRpcUrl = process.env.JSON_RPC_URL const web3 = Helpers.initWeb3(httpsUrl) const web3Socket = Helpers.initWeb3Socket(wssUrl)



Then I want to connect to a smart contract in order to see the events being emitted.

let factoryContract = Helpers.initContract(web3Socket, factoryABI, factoryAddress) trackPairCreatedEvent(factoryContract) function trackPairCreatedEvent(factoryContract) { trackEvent( factoryContract.events.PairCreated(), handlePairCreatedEvent ) } function trackEvent(event, callback) { event .on('data', callback) .on('error', console.error) }


I can see that node has received the WS connection

I[2021-03-25|03:27:17.455] New websocket connection remote=127.0.0.1:59376 I[2021-03-25|03:27:17.455] Starting wsConnection remote=127.0.0.1:59376 impl=wsConnection



But the node.js process the crashes with an error

[25.03.2021 03:21.34.630] [ERROR] Error: Returned error: Method not found at Object.ErrorResponse (/Users/ok/Workspace/aimbot/node_modules/web3-core-helpers/lib/errors.js:28:19) at Object.callback (/Users/ok/Workspace/aimbot/node_modules/web3-core-requestmanager/lib/index.js:303:36) at /Users/ok/Workspace/aimbot/node_modules/web3-providers-ws/lib/index.js:114:45 at Array.forEach (<anonymous>) at WebsocketProvider._onMessage (/Users/ok/Workspace/aimbot/node_modules/web3-providers-ws/lib/index.js:102:69) at W3CWebSocket._dispatchEvent [as dispatchEvent] (/Users/ok/Workspace/aimbot/node_modules/yaeti/lib/EventTarget.js:115:12) at W3CWebSocket.onMessage (/Users/ok/Workspace/aimbot/node_modules/websocket/lib/W3CWebSocket.js:234:14) at WebSocketConnection.<anonymous> (/Users/ok/Workspace/aimbot/node_modules/websocket/lib/W3CWebSocket.js:205:19) at WebSocketConnection.emit (node:events:376:20) at WebSocketConnection.processFrame (/Users/ok/Workspace/aimbot/node_modules/websocket/lib/WebSocketConnection.js:554:26) at /Users/ok/Workspace/aimbot/node_modules/websocket/lib/WebSocketConnection.js:323:40 at processTicksAndRejections (node:internal/process/task_queues:75:11) { data: null }

Everything works perfectly when I used the URLs provider by ANKR (same as infura in ETH), but I don't understand why an error is thrown when I try to use the local light node?

So the answer is that I was trying to connect using "Binance Chain" light node which is not EVM compatible, in order to connect to BSC Geth must be used according to https://github.com/binance-chain/bsc

Hope this helps!
