@Hero909 the code i sent seem to work,
(https://rinkeby.etherscan.io/tx/0xa376606e715c005f779b16356ac68d848df2ae5a332ba372d6d2cddc3abf0f3e) this is the transaction (i sent my custom erc20 token to someone), make sure when using metamask as default, you are scanning the qr code on the network you are sending the transaction on

Thanks a lot for your help guys !
@0xprof which code are you referring to ?
Were your custom erc20 token from the contract I shared ?
I tripled checked and I am using mumbai on metamask and metamask is set as default in unity ( on mumbai too)
I canât sea what is wrong 
Thanks again !
@0xprof I figured it out !
I donât know why but it works only when I increase the gas fees for the transactions quiet a lot.
Any Idea how I can lower that limit ? is it when deploying the smart contract ?
Thanks very much guys !
oh, i forgot
since it was a demo, i have to manually place the gas and i didnt mention it here (it wouldnt fail, but will show me a popup about gas been too low) i thought it would be the same.
you can set custom gas, it is in the readme of the boilerplate (https://github.com/ethereum-boilerplate/ethereum-unity-boilerplate#web3), although if i have time i will put it in my own example.
always take a look at the readme to help you understand , you can read it and see where gas is been passed
this will have something to do with gasfee, i have done it on mumbai, you just have to bump the gasfee to the right amount

The WebGL / Metamask Integration Pre-Release Package has been published.
This has been tested as desktop and WebGL using Unity 2020.3.26 & 2020.3.29.
NOTE: A new step upon import - in Player Setting when build is set to WebGL, under Resolution and Presentation select the Moralis WebGL template (see the Readme in the features/webgl-metamask branch (https://github.com/ethereum-boilerplate/ethereum-unity-boilerplate/tree/features/webgl-metamask)
The WebGL/Metamask integration is done. Still need to synchronize the interface to Wallet Connect / Nethereum function calls to match the new interface.

Hi. Is there a way to update an existing data row for a custom object? For example, Iâd like to find the row associated with a matching wallet address in a custom PlayerData object and then save data to that row (e.g., TokensCollected). Thanks!
var user = await MoralisInterface.GetUserAsync();
var walletAddress = user.authData[âmoralisEthâ][âidâ].ToString();
MoralisQuery player = await MoralisInterface.GetClient().Query();
var dataRow = player.WhereEqualTo(âWalletAddressâ, walletAddress);
//Update TokenBalance for this specific rowâŚ

Yes, this is possible.
You want to query a custom table, not the user table correct?
Say you have this object:
class PlayerStats : MoralisObject
{
public PlayerStats() : base("PlayerStats") {}
public string Name {get; set; }
public string WalletAddress {get; set; }
}
To query an existing player by WalletAddres:
user = await MoralisInterface.GetUserAsync();
var walletAddress = user.authData["moralisEth"]["id"].ToString();
// Create query
#if UNITY_WEBGL
MoralisQuery<PlayerStats> playerStatsQuery = await MoralisInterface.GetClient().Query<PlayerStats>();
playerStatsQuery = playerStatsQuery.WhereEqualTo("WalletAddress", walletAddress);
#else
MoralisQuery<PlayerStats> playerStatsQuery = MoralisInterface.GetClient().Query<PlayerStats>().WhereEqualTo("WalletAddress", walletAddress);
#endif
// Run query
IEnumerable<PlayerStats> result = await playerStatsQuery.FindAsync();
// Assunig there shou8ld only be a single row returned.
PlayerStats ps = result.FirstOrDefault();
// Change row data
ps.Name = "Clem the bold";
// Save changes
await ps.SaveAsync();
Happy coding,
David

Hi @dgoodrich
I have tested the pre-release with Unity v2020.3.27 and it is working fine. But with Unity v2021.2.5 iâm getting this error on Metamask wallet connect:
MRLW.framework.js.gz:3 NotSupportedException: /Applications/Unity/Hub/Editor/2021.2.5f1/Unity.app/Contents/il2cpp/libil2cpp/icalls/mscorlib/System.Runtime.InteropServices/RuntimeInformation.cpp(34) : Unsupported internal call for IL2CPP:RuntimeInformation::GetRuntimeArchitecture - "This icall is not supported by il2cpp on this architecture."
Rethrow as TypeInitializationException: The type initializer for 'System.Runtime.InteropServices.RuntimeInformation' threw an exception.

Thanks for posting. We have some up coming changes for all the jslib packages for Unity version > 2021.
I will add the âSystem.Runtime.InteropServices.RuntimeInformationâ as well.
Hi there,
I am sorry i donât understand, even with the readme 
I donât want to set custom gas fees and I canât find which one of your scripts is responsible for that.
Maybe something I am missing in the whole logic of it but its the network that sets the gas fee no ?
Thanks again for your time.
Hi @dgoodrich,
I canât seem to make the AwardableController.cs works.
I am simply trying to send a NFT minted with an ERC1155 between two players.
I try to use the SafeTransferFrom function like this:
public string ABINft;
public async void NftTransfer()
{
MoralisInterface.InsertContractInstance("NFT", ABINft, "mumbai", nftAddress);
Function f = MoralisInterface.EvmContractFunctionInstance("NFT", "mumbai", "safeTransferFrom");
Debug.Log(f);
string jsonresult = await f.SendTransactionAsync(senderAccount, receiverAccount, 2, 1, 0);
print(jsonresult);
}
Where the âsenderAccountâ owns the ID number 2 from the nftAddress (ERC1155 contract address).
The transfer fails like shown here:
What am I missing ?
Thanks a lot for your time and support!
you dont want to set custom gas ? then what are you looking for ?
i didnt set custom gas in any of my script, but i am still updating it,
and send the contract code for the erc 1155
Hello ! thanks for the reply !
since it was a demo, i have to manually place the gas
sorry maybe I misunderstood, I donât want the players to have to change the gas limit on metamask everytime they want to transact. If I donât significantly increase this value the transaction fails
And this is the contract code for the erc1155:
// SPDX-License-Identifier: MIT
// contracts/NftTrader.sol
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC1155/presets/ERC1155PresetMinterPauser.sol";
contract YTTokens is ERC1155PresetMinterPauser {
uint256 public gameIDCounter;
mapping(string => uint256) public idmap;
mapping(uint256 => string) public lookupmap;
constructor() ERC1155PresetMinterPauser("") { //base URI
}
function addGameID( string memory gameID, uint256 initialSupply ) external {
require(hasRole(MINTER_ROLE, _msgSender()), "YTTokens: must have minter role to mint");
require(idmap[gameID] == 0, "YTTokens: This gameID already exists");
gameIDCounter = gameIDCounter + 1;
idmap[gameID] = gameIDCounter;
lookupmap[gameIDCounter] = gameID;
_mint(msg.sender, gameIDCounter, initialSupply, "");
}
function uri(uint256 id) public view virtual override returns (string memory) {
return string( abi.encodePacked( super.uri(id), lookupmap[id]));
}
function getAllTokens(address account) public view returns (uint256[] memory){
uint256 numTokens = 0;
for (uint i = 0; i <= gameIDCounter; i++) {
if ( balanceOf(account, i) > 0) {
numTokens++;
}
}
uint256[] memory ret = new uint256[](numTokens);
uint256 counter = 0;
for (uint i = 0; i <= gameIDCounter; i++) {
if ( balanceOf(account, i) > 0) {
ret[counter] = i;
counter++;
}
}
return ret;
}
}
yes, you can set custom gas in code and add them to the parameters, so the user dont have to touch the gass and go straight to accepting the transaction.
you can look at this from the readme
Nethereum.Hex.HexTypes.HexBigInteger g = new Nethereum.Hex.HexTypes.HexBigInteger(80);
Nethereum.Hex.HexTypes.HexBigInteger wei = new Nethereum.Hex.HexTypes.HexBigInteger(1000);
string jsonResult = await func.CallAsync(playerAddress, new Nethereum.Hex.HexTypes.HexBigInteger(80), new Nethereum.Hex.HexTypes.HexBigInteger(1000), pars);
you can also take a look at the nethereum docs
(http://docs.nethereum.com/en/latest/)
can you show me what the SafeTransferFrom function look like ?
you may need to use this method
string playerAddress = "0x37bd48252f4dcE15C7147eA82b31978a00750f81";
object[] pars = {2, 1,0};
Nethereum.Hex.HexTypes.HexBigInteger g = new Nethereum.Hex.HexTypes.HexBigInteger(80);
Nethereum.Hex.HexTypes.HexBigInteger wei = new Nethereum.Hex.HexTypes.HexBigInteger(1000);
string jsonResult = await func.CallAsync(senderAccount, new Nethereum.Hex.HexTypes.HexBigInteger(80), new Nethereum.Hex.HexTypes.HexBigInteger(1000), pars);
or try
string jsonresult = await f.SendTransactionAsync(senderAccount, new Nethereum.Hex.HexTypes.HexBigInteger(80), new Nethereum.Hex.HexTypes.HexBigInteger(1000), pars);
print(jsonresult);
if this doesnât work, no worries, i am writing a demo right now and will update you when i am done

Hello everyone,
I am using Moralis SDK for Unity. I am trying to fetch my NFTs using :
async void Fun()
{
NftOwnerCollection balance = await MoralisInterface.GetClient().Web3Api.Account.GetNFTsForContract(address.ToLower(), tokenAddress, ChainList.eth);
}
Ref : https://github.com/ethereum-boilerplate/ethereum-unity-boilerplate#getnftsforcontract
The above code is working fine on PC, but returning null on Android. Please help.
