Hi guys I have a question for you. I knew that in order to swap eth with erc20 tokens on uni it requires to have a wrapped eth. But when using it with metamask it did accepted my eth straight away without the need to convertit into weth first

Yes it's normal. I guess the interaction with contract will make your ethereum to be swapped into WETH automatically and when you're converting something (i.e token) your token will be considered into the ethereum automatically. The process has been done by the smartcontract that already programmed to swap your native ethereum into the WETH(erc20 ethereum)

...is it normal? tks

Yes it is normal. This is an example https://etherscan.io/tx/0xe79b02313d406393f2a7046ff4d0f75aa2fd0bc632b790db1593d6851046b8bf

Your ethereum will be sent to the custodian wallet as collateral and the contract will be sending WETH for that.
