UniswapError: invalid from or to contract tokens #20
Im trying to use one of the examples from this repo but I keep getting this error and I can not find the reason why. I am trying to use my chainstack node provider URL which works with other modules like web3 without issues.
const uniswapPair = new UniswapPair({
// the contract address of the token you want to convert FROM
fromTokenContractAddress : '0xdac17f958d2ee523a2206206994597c13d831ec7',
// the contract address of the token you want to convert TO
toTokenContractAddress : '0x2b591e99afe9f32eaa6214f7b7629768c40eeb39',
// the ethereum address of the user using this part of the dApp
ethereumAddress : '0x1624c82cdac2f518ab47ef34f497af268b6d7916',
chainId : ChainId.MAINNET,
providerUrl :
'myusernamen:myuserpassword@nd-095-386-530.p2pify.com',
settings : new UniswapPairSettings({
// if not supplied it will use 0.005 which is 0.5%
// please pass it in as a full number decimal so 0.7%
// would be 0.007
slippage : 0.005,
// if not supplied it will use 20 a deadline minutes
deadlineMinutes : 20,
// if not supplied it will try to use multihops
// if this is true it will require swaps to direct
// pairs
disableMultihops : false,
// for example if you only wanted to turn on quotes for v3 and not v3
// you can only support the v3 enum same works if you only want v2 quotes
// if you do not supply anything it query both v2 and v3
uniswapVersions : [
UniswapVersion.v2,
UniswapVersion.v3
]
})
});
