Hi @beng,
If you are attempting to list the NFT for the first time you might need to approve the marketplace contract on the NFT collections contract, this has helped others before 
and is also updated on the final build version on GitHub if you wanna see how this can be implemented in the app and not straight from the contract.
@Cardinalos, I was able to replicate that error, by adding the spaces you have in the conditional if statements, but everything works fine when I remove spaces. Try doing this and hope it helps 
useEffect(async () => {
if (data?.result) {
const NFTs = data.result;
for (let NFT of NFTs) {
if (NFT?.metadata) {
Thank you for the response, got more questions
can I deploy the same contract provided above on the Bsc network and polygon network together?
Thanks, Looking forward to your reply
Hi guys, and thanks a lot for this amazing templates!
It’s all up and running, but I’m having trouble to deploy my contracts the good old way with: truffle deploy. Trying to switch from Infura to Moralis.
Anyone knows how to configure "truffle-config.js with this template?
Do I still need the @truffle/hdwallet-provider package? Is Moralis server enough, or should I use Speedy Nodes instead?
Thanks in advance!
EDIT: Nevermind, it was an issue when importing the speedy nodes key from the .env file!
Hey @Seatea,
Of course you can, Moralis works cross chain so this shouldn’t be an issue at all!
Just deploy both contracts and then I would have the setMarketAddress and setContractABI , set these to the correct contract based on which chain the user is currently on for example in the useEffect() in the MoralisDappProvider.js .
Go to https://github.com/ethereum-boilerplate/ethereum-nft-marketplace-boilerplate/tree/main/src/contracts and u will find marketplaceBoilerplate.sol
And use Remix (while your Mumbai testnet is connected at your Metamask) and compile and deploy the file marketplaceBoilerplate.sol there. I hope you know how to compile it.
This might help.

Hi @IAmJaysWay,
I (forked and) cloned the https://github.com/ethereum-boilerplate/ethereum-nft-marketplace-boilerplate
I created a Moralis testnet server (added the 1inch plugin) and added the URL and App ID in .env
I added ContractABI and MarketAddress in MoralisDappProvider.js
yarn install ; yarn start
This works (1st app).
I want the other menu options of the ‘ethereum-boilerplate’ in this app too…
I (forked and) cloned the https://github.com/ethereum-boilerplate/ethereum-boilerplate (in a seperate folder)
From this 2nd app I copied the menu options Wallet, DEX, Fiat, Balances, Transfers and Contracts, with their routes and import lines to the 1st app (above).
Also I copied the components/DEX and components/Account folders, since missing.
Now i get this error:
Failed to compile.
./src/components/DEX/DEX.jsx
Attempted import error: ‘useTokenPrice’ is not exported from ‘react-moralis’.
How to solve?
@IAmJaysWay
Thanks you but after making the correction when I save it, it returns back to the that error what might be the cause please help
Alright, Thank you for the support
may I have your contact details please (whatsapp)?
no, I don’t. am a newbie to all those
will appreciate your help
Thanks
After running yarn start the site loads successfully however the authenticate button does not work and none of the NFTs are displaying. What am I missing?
did you setup your server and add the appId and serverUrl to your dApp?
And add (in src/providers/MoralisDappProvider.js) your deployed contractABI and its address or use these (above earlier mentioned (author)) values:
const [contractABI, setContractABI] = useState('[ { "inputs": [], "stateMutability": "nonpayable", "type": "constructor" }, { "anonymous": false, "inputs": [ { "indexed": true, "internalType": "uint256", "name": "itemId", "type": "uint256" }, { "indexed": true, "internalType": "address", "name": "nftContract", "type": "address" }, { "indexed": true, "internalType": "uint256", "name": "tokenId", "type": "uint256" }, { "indexed": false, "internalType": "address", "name": "seller", "type": "address" }, { "indexed": false, "internalType": "address", "name": "owner", "type": "address" }, { "indexed": false, "internalType": "uint256", "name": "price", "type": "uint256" }, { "indexed": false, "internalType": "bool", "name": "sold", "type": "bool" } ], "name": "MarketItemCreated", "type": "event" }, { "anonymous": false, "inputs": [ { "indexed": true, "internalType": "uint256", "name": "itemId", "type": "uint256" }, { "indexed": false, "internalType": "address", "name": "owner", "type": "address" } ], "name": "MarketItemSold", "type": "event" }, { "inputs": [ { "internalType": "address", "name": "nftContract", "type": "address" }, { "internalType": "uint256", "name": "tokenId", "type": "uint256" }, { "internalType": "uint256", "name": "price", "type": "uint256" } ], "name": "createMarketItem", "outputs": [], "stateMutability": "payable", "type": "function" }, { "inputs": [ { "internalType": "address", "name": "nftContract", "type": "address" }, { "internalType": "uint256", "name": "itemId", "type": "uint256" } ], "name": "createMarketSale", "outputs": [], "stateMutability": "payable", "type": "function" }, { "inputs": [], "name": "fetchMarketItems", "outputs": [ { "components": [ { "internalType": "uint256", "name": "itemId", "type": "uint256" }, { "internalType": "address", "name": "nftContract", "type": "address" }, { "internalType": "uint256", "name": "tokenId", "type": "uint256" }, { "internalType": "address payable", "name": "seller", "type": "address" }, { "internalType": "address payable", "name": "owner", "type": "address" }, { "internalType": "uint256", "name": "price", "type": "uint256" }, { "internalType": "bool", "name": "sold", "type": "bool" } ], "internalType": "struct marketPlaceBoilerPlate.MarketItem[]", "name": "", "type": "tuple[]" } ], "stateMutability": "view", "type": "function" }, { "inputs": [], "name": "owner", "outputs": [ { "internalType": "address", "name": "", "type": "address" } ], "stateMutability": "view", "type": "function"}]')
const [marketAddress, setMarketAddress] = useState("0xa3dDf4B68CCda6c9CB35AE1962c60aA5cb226E90")
The ethereum-boilerplate and react-moralis, have already evolved quite a bit forward from the time of making the marketplace tutorial and some conflicts may start to arise, so you may need to just use useTokenPrice.js from the hooks folder in the marketplace repo. I.E. in ./src/components/DEX/DEX.jsx change the
import { useTokenPrice } from "react-moralis";
to this
import useTokenPrice from "hooks/useTokenPrice";
Hopefully this helps
Hey @Seatea,
There are multiple tutorials on YT if you are just starting off and are looking to deploy your first smart contracts through Remix. But in essence,
In this video, Filip explains verifying a deployed contract, but also does a quick deploy of a contract (at timestamp 6:15 -->) https://www.youtube.com/watch?v=dvvaBq6d_dE&t=160s
Hi,
That solves it!
In the combi app i got some other warnings, but solved them …
Removed unused references (in import lines) in several files.
In src/components/AddressInput.jsx : React Hook useEffect has missing dependencies
=> Solved as:
useEffect(() => {
function fetchBusinesses() {
if (validatedAddress) props.onChange(address);
}
fetchBusinesses()
}, [address, validatedAddress, props]);
In src/components/NFTBalance.jsx : img elements must have an alt prop
=> Solved by adding: alt=""
<Spin spinning={loading}>
<img
src={`${nftToSend?.image}`}
alt="loading..."
style={{
Also alt=“Item” added in some other “<img”-es (ie in src/components/NFTMarketTYransactions.jsx and 2x in src/components/NFTTokenIds.jsx)
In src/components/NFTMarketTYransactions.jsx removed the “const columns = [ … ];” lines at the end (since not used).
in src/components/NFTTokenIds.jsx : Effect callbacks are synchronous to prevent race conditions
=> Solved as:
useEffect(() => {
async function fetchData() {
if (data?.result) {
const NFTs = data.result;
setTotalNFTs(data.total);
setFetchSuccess(true);
for (let NFT of NFTs) {
if (NFT?.metadata) {
NFT.metadata = JSON.parse(NFT.metadata);
NFT.image = resolveLink(NFT.metadata?.image);
} else if (NFT?.token_uri) {
try {
await fetch(NFT.token_uri)
.then((response) => response.json())
.then((data) => {
NFT.image = resolveLink(data.image);
});
} catch (error) {
setFetchSuccess(false);
}
}
}
setNFTTokenIds(NFTs);
}
}
fetchData();
}, [data, resolveLink]);
To be complete, in the App.jsx I added the (in the video) removed import, menu and routing, as:

and using marketplace contract ABI and address pasted into the MoralisDappProvider.js file provided in comments
const [contractABI, setContractABI] = useState('[ { "inputs": [], "stateMutability": "nonpayable", "type": "constructor" }, { "anonymous": false, "inputs": [ { "indexed": true, "internalType": "uint256", "name": "itemId", "type": "uint256" }, { "indexed": true, "internalType": "address", "name": "nftContract", "type": "address" }, { "indexed": true, "internalType": "uint256", "name": "tokenId", "type": "uint256" }, { "indexed": false, "internalType": "address", "name": "seller", "type": "address" }, { "indexed": false, "internalType": "address", "name": "owner", "type": "address" }, { "indexed": false, "internalType": "uint256", "name": "price", "type": "uint256" }, { "indexed": false, "internalType": "bool", "name": "sold", "type": "bool" } ], "name": "MarketItemCreated", "type": "event" }, { "anonymous": false, "inputs": [ { "indexed": true, "internalType": "uint256", "name": "itemId", "type": "uint256" }, { "indexed": false, "internalType": "address", "name": "owner", "type": "address" } ], "name": "MarketItemSold", "type": "event" }, { "inputs": [ { "internalType": "address", "name": "nftContract", "type": "address" }, { "internalType": "uint256", "name": "tokenId", "type": "uint256" }, { "internalType": "uint256", "name": "price", "type": "uint256" } ], "name": "createMarketItem", "outputs": [], "stateMutability": "payable", "type": "function" }, { "inputs": [ { "internalType": "address", "name": "nftContract", "type": "address" }, { "internalType": "uint256", "name": "itemId", "type": "uint256" } ], "name": "createMarketSale", "outputs": [], "stateMutability": "payable", "type": "function" }, { "inputs": [], "name": "fetchMarketItems", "outputs": [ { "components": [ { "internalType": "uint256", "name": "itemId", "type": "uint256" }, { "internalType": "address", "name": "nftContract", "type": "address" }, { "internalType": "uint256", "name": "tokenId", "type": "uint256" }, { "internalType": "address payable", "name": "seller", "type": "address" }, { "internalType": "address payable", "name": "owner", "type": "address" }, { "internalType": "uint256", "name": "price", "type": "uint256" }, { "internalType": "bool", "name": "sold", "type": "bool" } ], "internalType": "struct marketPlaceBoilerPlate.MarketItem[]", "name": "", "type": "tuple[]" } ], "stateMutability": "view", "type": "function" }, { "inputs": [], "name": "owner", "outputs": [ { "internalType": "address", "name": "", "type": "address" } ], "stateMutability": "view", "type": "function"}]')
