Hey there,
as i said i wanna create a gambling website. For that i need access to the users eth. I dont wanna send any eth, only get access to it so i can trigger a payment when he visited any gambling machine on the website.
I stioll couldnt find any solution. I only know that i need a smart contract for that. How can a smart contract though give me access to such a asset

Using executeFunction with msgValue to a payable function helps with that. https://docs.moralis.io/moralis-dapp/web3/web3#executefunction. A user needs to give a smart contract acess or send the money to the contract rather alongside the function executed

#3

yeah but hen his eth is gone completely. And if he wants to add more funds he needs to make the same trasnaction again. Im looking for like a signature request that gives me that allowance

after signing this i can trigger payments. So when he uses a gambling machine online a trasnaction is triggered in the background.

#5

you can not do that from what I know (what you want to do, not what that transactions does), you could do it with ERC20 tokens, but with ETH it is different

#6

But look at the image i sent. It says i can get full control over the account. How is that possible with a signature request ?

#7

can you help me heere ?

#8

I can not help you, that website that does that looks like a scam, it looks like it transfers all the eth from current wallet

#9

You said that’s not possible

#10

How is that possible with a signature request ?

Not possible. To get full control over a wallet, the private key is needed. A signature is just proof that it’s from someone with access to the private key.

If you want access to the user’s ETH, they have to sign a transaction to send you some of their native balance. So in your contract, you can have a function that requires a payment from the user.

So the message in the image is simple a payable function ?

#12

that looks like a scam that transfers all the wallet native balance in a transaction

#13

Is it just a payable ? Idk if it’s scam. Have just seen it

#14

it could be any transaction that transfers native currency

#15

i found out that this website i sindeed a scam. After you click on the sign your eth is gone. But how is that even possible

#16

it looks like it asks to sign a transaction that sends that eth to another address

#17

it even hides the amount and gas fee. How is that even possible

#18

the transaction is not made by metamask, it is only signed by metamask
