not working on goerli test network? #3

Closed ctrngk closed 3 years ago

ctrngk commented 3 years ago

const uniswapPair = new UniswapPair({ fromTokenContractAddress: '0xf74a5ca65e4552cff0f13b116113ccb493c580c5', toTokenContractAddress: '0x2ac3c1d3e24b45c6c310534bc2dd84b5ed576335', chainId: ChainId.GÖRLI, ... }) which returns 

UniswapError: invalid from or to contract tokens

Those goerli tokens are from https://explorer.bitquery.io/goerli/tokens which should be valid

Hey thanks for raising it, I have now made this support goerli just so you know your query will now return

UnhandledPromiseRejectionWarning: UniswapError: No routes found for 0xf74a5ca65E4552CfF0f13b116113cCb493c580C5 > 0x2aC3c1d3e24b45c6C310534Bc2Dd84B5ed576335 < but that's a normal error from the lib it can not found any route paths to take you so make sure the tokens you are querying all have pools to weth!

simple-uniswap-sdk@2.2.0 holds the fix
