Hey guys
hope you all be fine and doing well

Is there anybody knows about how we can have implement payments in dapp development, with using an ERC20 compatible token, other than native coin of the network?

Just configure the payment button on the dapp to take payments using the ERC20 token of your choice...

I meant, gas fees deductible with erc-20 tokens(other than ETH)

Gas fees by default are done using the native token. That cant be bypassed...

Yes, you’re saying by default. But with account abstraction in eip4337 it is possible to do gas abstraction

But I don’t know how exactly to implement it

I think you are getting the entire think mixed up mate...

?

First, a user creates a UserOperation object and submits it to the mempool. The Bundler then receives the UserOperation and submits it to the EntryPoint for verification and execution. The EntryPoint verifies the UserOperation is valid by checking the Contract Account and if needed the Paymaster and Aggregator, and then sends the call data to the Wallet Contract for execution. Any unused gas fees are refunded to the Wallet Contract or a function is called on the Paymaster Contract to run any post-execution logic.

You'll find more information here mate...

So how can we implement a system when user does not have eth in his balance and just have for example usdt, but be able to send transaction with gas reduction from usdc ?

The contract needs to have some native tokens in order to work even if the user doesn't...

In that case, Can we deduct the gas fee from user token balance when he as an example, wants to withdraw the funds?

That should work, then the contract will retain the funds then swap to ETH just to maintain the native balance for subsequent interactions with the contract...

I think it will do the job, do you think so?

Definitely, just implement the logic in the contract...

Thanks a lot for helping🙏
I guess know it is more clear to me

Always a pleasure mate...

Also I have seen in some platforms, they split gas fees into 2slices.
One slice goes to the miner, and the other slice goes to a different wallet.
I was very curious how it is happening like that?

you have to use paymaster for that

1: User tokens get deducted,
2: Paymaster pays for the gas
3: User pays to pay master in tokens
4: Tokens swapped in the tx to eth/weth

but tokens will need the permit() function check out Oz's permit extension with paymaster contracts

Hi, shall we use this for production..

Yes you can...
