Does bob have to pay for 2 transactions? 1 for permit and 1 for transferFrom? (I've always wondered why these can't be combined into 1 transaction, from the day I first started "defi-ing").

you make this look so early, love what you do.
This was great, thanks. Would love to see a ctf using this concept.
It would be fun to go over some of the proposed transaction relayer standards, or maybe some details around permit2. Keep up the good work 👍
Both would be amazing!
i love the work you do it really helps me alot
So, basically, it's not gassless. The gas does get paid but by the receiver or a compensated third party.
yes, and you can create abstraction on top of EVM and not require any native token to be on your users wallets, only gas-less signatures

nice content❤
Also do they need to trust Carol?

Only Carol pays for fee
Bro will this work with existing ERC20 contracts ? like DAI, USDT and all ?
Only if ERC20 supports permit
I think both DAI and USDT supports permit
DAI has Erc20permit
make a tutorial videos on gasless transaction .
How did Alice send the message to bob without paying for it ?
Message can be sent via internet, such as email or chat
@@smartcontractprogrammer but where the blockchain plays role in it?
And can this be done through web3 js
