How to Access Binance Chain?

[taeguscromis]

In Binance Chain docs: here we can see that accessing it with Web3 is easy

const Web3 = require('web3');
// mainnet
const web3 = new Web3('https://bsc-dataseed1.binance.org:443');

// testnet
const web3 = new Web3('https://data-seed-prebsc-1-s1.binance.org:8545');

Is there any way to do the same with ethers without wrapping web3? Thanks.

If is is a normal JSON-RPC endpoint, you can just use: new ethers.providers.StaticJsonRpcProvider(url) passing in your binance url.

But I’ve not used Binance before, so I may be mistaken.

Thank you for the quick reply. Just a question. If I use StaticJsonRpcProvider, do I still have all of the functionality of ethers available as in case of defaultProvider? Why I am asking is because I have a bridge between ETH and another chain and we are now scaling to Binance. and I would like to reuse my code. Binance is a copy / paste of ETH otherwise.

By functionaliy I meant the functions in "provider" class. Also yes Binance chain should be 100% ETH compatible but we will see.

Would be good to study this, as Binance is getting very popular due to low fees

As long as the functionality also exists in Binance, Yupp! :)

The default provider just uses well-known Ethereum third party services, like INFURA and Alchemy.

There is no difference from if you manually created providers for Ethereum yourself, it’s just a convenience function. :)

Perfect. Just what I wanted to hear. Thank you. I was not sure about it at first as for instance Etherscan I know has some additional functionality in their APIs

There is a PR for an Etherscan extension for Binance, but I think it makes more sense as an ancillary package than as part of ethers core. I haven’t heard of Binance outside of that PR. :)

But I’m going to break some functionality out in v6 to make that the EtherscanProvider extensible for Binance.

Well, they are taking a big share right now simply because of fees on ETH. That is why BNB mooned lately. I think having pluggable chain agnostic library would be a huge plus. There is also Polkadot, but I have no clue how different that is.

What is for sure is that in the future everything will have to communicate across different chains and ecosystems in

Hi @taeguscromis
have you got the BSC working with ethers.js.
Thanks for your reply
