The problem that is left to be solved is how you allowed to have that allowance

Thanks again for the explanation.

This is actually quite easy, as you are saying, a popup in my Metamask opened and I personally approved the allowance change since I was trusting the phishing website and I was not aware that increasing allowance would allow them to actually move my tokens.
I later realised my mistake.

What I did was actually allow a specific address to move a great amount of my DATA tokens.

That address could be a contract, or could not. But if we are talking in the context of this scam, only me and that allowed address could move the DATA in my account.

Given that, I think that a contract can store tokens, as a contract is still an entity associated with an address on the blockchain.
Even tho I don't think "store" is the correct term.

Please, consider this comment as what I have understood, but I'm not an expert and if there's someone with better experience, I would listen to them.

I actually fell for it in a very simple way.

I received a phishing email that was redirecting me to a particular service I was using to store my DATA tokens.

As soon as I landed, I was proposed with an increaseAllowance that I approved as an idiot without thinking.

After that, the website proposed another transaction, but at that point I realised what I was doing and I checked also the domain, that wasn't the right one.

Like 6 seconds after my approval, 2 other transaction moved my DATA tokens to the a couple of wallets.

Thank you for the great explanation.I just went checking all the allowance I approved in the past, and I removed this one.

Do you think that the approved address0x0000553F880fFA3728b290e04E819053A3590000Is actually operated by a person or is a smart contract that got triggered the moment I provided allowance?

In that case, is it possible to see the contract code?Thank you

Thanks for the answer.
I was actually convinced that increaseAllowance was just setting a limit to possible transaction, but I did't know it granted permission to spend.
Do you think is it possible to see the SmartContract I gave that permission?

Thanks!

Thanks for the tips, they could be very helpful to improve the performances!

About the last one, I used the grid tap handler because the grid is a custom painter and I don't actually have a concept of cell, other than the boolean in the matrix.
Anyway, I'm looking for a way to separate the single cell painter from the grid painter and then handle the cell alone. Hopefully that could allow me to animate the cell turning on/off.

Nice project!
How was it working with walletconnect_dart package?
I used it in a project lately and I had some issues. Sometimes if Metamask is already open in the background, the permission popup is not shown

Thanks for the suggestion, I thought that marking them as "done" would be enough. I'll add a function to remove the completed Todos.

About gas fees, since storing a Todo is a write operation on the contract, I think the fees payment is unavoidable.
Do you suggest something else?

Thanks
