Level 22 Dex - Sentry 429 (Too Many Requests) in MetaMask

[remedcu]

I have created an issue in MetaMask, which you can see here: MetaMask/metamask-extension#15000

This happens in approve transactions, and I use the command: await contract.approve(instance, 10000)

I even imported the contract to remix, deployed it to the instance address, and tried the GUI for approval, but still the same result.

Out of curiosity, I tried another level (23 and so on), which works well.

Is it a problem with Metamask, OpenZeppelin, or some weird bug just for me?

There's other ways to interact with a contract. I noticed this as well and was still able to solve it.

I created a pull request on this issue adding a hint, I didn't want to be so obvious about it, I could of hinted at what does "at address do???" I might do that

SPOILER ALERT
Head over to Remix.
Create a new contract called AnyToken.sol with the contents of:
import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol";
compile it
Then, right under the deploy button there's a button that says At Address
paste the address of await contract.token1() and click
After that, paste the address of await contract.token2() and click

I'm sure you can figure out the rest.

I was stoked to find out that was possible
