Testing the contract token

Smart Contracts
,
1

Hello
I'm having trouble testing the contract through sopelia
I don't know if uniswaprouter V2 supports sepolia
Because the deployment of the contract still fails
I wanted to test through goerli but the faucets don't work

I will be glad if someone helps me
When someone has time to look at my contract

Please provide the code of the token contract you're trying to deploy and test.

please, if someone can check it, I will be grateful

Plz share your contract codebase so that i can check.

I guess there was a net problem when you tried to deploy contract.
I deployed your contract to the goerli successfully.

yes, I see, thank you, I want to ask if the tax test will be done?
the point is that the 2% tax for liquidity is set in such a way that the 2% tax is 1% automatically converted to eth and then sent to liquidity but only when it reaches 0.05 eth due to the gas load.
