Can Puppet be solved in 1 transaction ?

[MiniGlome]

Hello,
The new release of the Puppet Challenge requires the player to use only 1 transaction to succeed. However, I don't see how this is possible since in order to solve the challenge, the player has to deploy a smart contract and approve the token. That's at least 2 transactions...

It is feasible and I have done it.

Any hints? how?

I suggest you spend some more time learning and trying. There is a flaw in the thirteenth challenge that I only discovered after watching it for five nights.

I can only assure you that this challenge is achievable.

Hey @MiniGlome, as @naiba was saying, it's possible. Keep looking ! 💪

Do you know a way to make the transaction signature on-chain using solidity.
I think I might have an idea to solve this.
Not able to find a way so that we can generate the signature on chain. Or maybe it's not possible. I don't know.
can you help to find this @MiniGlome @naiba

Finally solved the problem.
Yes it is achievable

Figuring out how to do it in a single transaction took me more time than the actual bug.
There are multiple "solutions" online, that simply deploy contract with eth already - that's not THE solution. 🤐
