Here is my repo If you or anyone wants to have a look. Everything you have said to do i have done unless i misinterpreted it. I have hit a wall right now.

Hey
I was able to get the list button to not throw a error at me on Mumbai but i sit here waiting for the transaction to go through and It just sits here loading. I had no luck getting the list button on Ropsten testnet to work

@johnversus This is the post I mentioned

johnversus · July 27, 2022, 6:15am

You clicked on the confirm button and it is still loading?

can you share your contract address and chain name where it is deployed?

KyeG · July 27, 2022, 6:17am

Yes i sat waiting for it finish loading and it never did so i cancelled the transaction.
0xd9145CCE52D386f254917e481eB44e9943F39138 is my contract address and i deployed the contract to Mumbai.
Cheers

What happens when you click on the confirm button in metamask?

johnversus · July 27, 2022, 6:24am

I think this is the wrong contract address. As per the polygon scan this is an erc20 contract.

You need to deploy the contract address from here and use that address.

I hit confirm then i sit here for ages watching it load but the transaction doesn’t go through

KyeG · July 27, 2022, 6:28am

@johnversus I deploy that contract above and put its contract address in my moralisdappprovider?
Cheers

johnversus · July 27, 2022, 6:31am

Yes, That’s the contract that is used in the tutorial.
Also make sure the ABI used in the moralisdappprovider is of the same contract.

KyeG · July 27, 2022, 6:46am

Okay im double checking it now. Maybe my internet isn’t the best and why its taking so long for the transaction to go through lol

KyeG · July 27, 2022, 10:53am

This is what I’m getting now. Do i need to change my RPC URL?

I dont know what that error is related to.
Which function caused this error?

KyeG · July 27, 2022, 8:35pm

@johnversus
This happens from the list function.

KyeG · July 27, 2022, 10:14pm

@johnversus I’ve read online its a transaction underpriced error.

alex · July 27, 2022, 10:32pm

You can try setting higher gas in MetaMask. Have any of your list function calls been confirmed (and checked on the chain explorer)?

KyeG · July 27, 2022, 10:34pm

@alex Ok ill try setting a higher gas price. None of the listings have gone through as transaction successful. I go on chain explorer and it says pending.

KyeG · July 27, 2022, 10:39pm

Hey @alex
The metamask error Im getting now is different to before. All i changed was the listing price from ETH to MATIC. I’ve never heard of a EIP-1559 transaction.

alex · July 27, 2022, 10:53pm

All i changed was the listing price from ETH to MATIC

What do you mean by this exactly? What did you do in code?

Didn’t you get past this EIP-1559 error before? E.g. with changing the chain and/or RPC.

KyeG · July 27, 2022, 11:04pm

Hey @alex
I changed where it says listing price in ETH to listing price in MATIC.
I can change it back if need be. The RPC I was told to use was the original RPC URL I was using.

Listing in ETH
