ERC20 Permit Tutorial - Allow users to approve token transfers without spending gas (EIP 2612)

[@thomascherret3180]

thanks for the video, I was looking for information on it. Your video gave all the info I was looking, well done!

[@cryptogenik]

Great video - I think a lot of commenters here misunderstand that somehow this allows you to transfer tokens without paying gas and that's not what this does. It allows you to not require the users to pay for an approval transaction from another contract, you can just approve and send tokens all in one transaction. Right?

@Web3_Club why we need to create http server & please show the process to connect server with this html file.

Hi, thank you for Tutorial. Everything works with MyToken, but when I'm forking mainnet and trying to do the same things with USDC it throwing an error: EIP2612: invalid signature. Maybe you know is there any difference between USDC and ERC20Permit ?

[@androidtechsayed201]

Probably usdc have not implemented this system

How can I transfer them after this? I tried with the transfer() erc20 method and it asks for a aditional signature with gas fees.. Can I use this for every token address (permit supported ones)?

[@Web3_Club]

Transfer by calling transfer from once the spender has approval. Should work with all permit related tokens

[@s.8494]

@@Web3_Club I used the same code from your video, I do get the permit logged in console (r, s and v), but when I call the transferFrom() method, it will make me sign again and asks for gas fees. I tried to use the contract transferfrom() method on etherscan, same problem... Any ideas? Thanks :D

[@s.8494]

Update: The transferFrom() method, won't do anything.

[@venom33cm17]

@@s.8494 Is it asking for the gas fees to the user even if the owner provides the spender with the coins?

[@notify7610]

Just coming in now @Web3 Club Please can I actually used the same code from your video, with out changing anything or the domain name and there wouldn't be any error? So I can start practicing immediately...🙂

[@Web3_Club]

Yes
