Binacne smart chain

[phatwasin01]

How can I solve this ?
const {ChainId, Fetcher, WETH ,Route,Trade, TokenAmount, TradeType} = require('@pancakeswap-libs/sdk'); const ethers = require("ethers") const chainId = ChainId.MAINNET; const tokenAddresss = '0x0e09fabb73bd3ade0a17ecc321fd13a19e81ce82'; const bscProvider = new ethers.providers.JsonRpcProvider('https://bsc-dataseed.binance.org/') const init = async() => { const cake = await Fetcher.fetchTokenData(chainId,tokenAddresss,bscProvider); const weth = WETH[chainId]; const pair = await Fetcher.fetchPairData(cake,weth); const route = new Route([pair], weth); console.log(route.midPrice.toSignificant(6)) console.log(route.midPrice.invert().toSignificant(6)) } init();
ERROR :
(node:12788) UnhandledPromiseRejectionWarning: Error: unsupported getDefaultProvider network (operation="getDefaultProvider", network={"chainId":56,"name":"unknown"}, code=NETWORK_ERROR, version=providers/5.0.24)

Does Binance support the eth_chainId operation? If you specify the network details explicitly, this error should go away. Something similar to { name: "binance", chainId: CHAIN_ID }, you will need to look up the binance chain ID for that.

Hey, don't mean to re-open this but i tried

const bscProvider = new ethers.providers.JsonRpcProvider('https://bsc-dataseed.binance.org/', { name: 'binance', chainId })

and I got:

reason: 'unsupported getDefaultProvider network', code: 'NETWORK_ERROR', operation: 'getDefaultProvider', network: { chainId: 56, name: 'unknown' }

Looking at the source, it seems you just pass the network object as a second parameter, what am I doing wrong?

Did you ever figure out?

The following did work on ethers 5.1. Are you sure you're getting error from that line?

bscProvider = new ethers.providers.JsonRpcProvider('https://bsc-dataseed.binance.org/', { name: 'binance', chainId: 56 })

Still getting this error on providing { name: "binance", chainId: 56 } on binance.

I've also added a new BSC package. Still very experimental, but try it out and let me know if you have any problems: https://github.com/ethers-io/ancillary-bsc

Or simply, npm install @ethers-ancillary/bsc.

Example of what? The repo gives an example of creating the provider…

Sorry, I'm a noob

And Have been trying all day to connect my project smart contract to bsc testnet with ethers.js with no luck

[lelerukjaymoh]

To connect to a network using ethers, create a provider instance using either of these 👇

If you are using a WebSocket endpoint,
const provider = ethers.providers.WebSocketProvider("NODE_WS_ENDPOINT"

If you are using a HTTP endpoint
const provider = ethers.provides.JsonRpcProvider("NODE_HTTP_ENDPOINT")

//for testnet
bscProvider = new BscscanProvider(97);
//or for main
bscProvider = new BscscanProvider(56);
