Base Network support

[alicercedigital]

How can we use the base network with this package?

I have defined customNetwork and cloneUniswapContractDetails, but when I try to use them, I get the message:

Can not find chain name for 8453. This lib only supports mainnet(1), ropsten(4), kovan(42), rinkeby(4) and görli(5)

This is my config:

 const uniswapPair = new UniswapPair({
  fromTokenContractAddress: "0x4200000000000000000000000000000000000006",
  toTokenContractAddress: "0x347F500323D51E9350285Daf299ddB529009e6AE",
  ethereumAddress: selectedAddress,
  ethereumProvider: metaMaskProvider,
  chainId: 8453,
  settings: new UniswapPairSettings({
   cloneUniswapContractDetails: {
    v2Override: {
     factoryAddress: "0x8909Dc15e40173Ff4699343b6eB8132c65e18eC6",
     routerAddress: "0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD",
     pairAddress: "0x0Aa352230c5C05Fa912DAC0B538551f79121e29B",
    },
    v3Override: {
     factoryAddress: "0x33128a8fC17869897dcE68Ed026d694621f6FDfD",
     routerAddress: "0x2626664c2603336E57B271c5C0b26F421741e481",
     quoterAddress: "0x3d4e44Eb1374240CE5F1B871ab261CD16335B76a",
    },
   },
   customNetwork: {
    nameNetwork: "Base Mainnet",
    multicallContractAddress: "0x275617327c958bD06b5D6b871E7f491D76113dd8",
    nativeCurrency: {
     name: "Ether",
     symbol: "ETH",
    },
    nativeWrappedTokenInfo: {
     chainId: 8453,
     contractAddress: "0x4200000000000000000000000000000000000006",
     decimals: 18,
     symbol: "WETH",
     name: "Wrapped ETH",
    },
   },
   slippage: 0.0005,
   deadlineMinutes: 10,
   uniswapVersions: [UniswapVersion.v2, UniswapVersion.v3],
  }),
 });

Has anyone used this package with Base network? If so, could you kindly provide the configuration you used? That would greatly help us; we have been struggling with the Uniswap SDK for almost a month now. We just want to use code to trade, and this package is our last hope. =/

[alicercedigital]

I have created a fork of this package and made changes to the following files: (https://github.com/alicercedigital/simple-uniswap-sdk)

uniswap-pair.ts Added the chainId to the createFactory() check

chain-id.ts Added the base chainId to the ChainNames and ChainId enum

tokens.factory.public.ts Added providerContext.customNetwork to the TokensFactoryPublic constructor

eth.ts and wth.ts Added the WETH address of the base network

ethers-provider.ts Added the RPC base mainet of Infura

Now we are receiving the error: unsupported network (argument="network", value={"chainId":8453,"name":"unknown"}, code=INVALID_ARGUMENT, version=providers/5.7.2)

This error is being thrown when we initialize new UniswapPair() Does anyone know which contract is throwing this error?
