Lokesh — Wed, 04 Sep 2024 07:28:54 +0000

Dear Team -

Please check this error response, that we are receiving since today morning. We are unable to deploy a contract using Xinfin Remix.

1) Tried this RPC URL : https://earpc.apothem.network - It is showing values and sometimes 0 xdc in the metamask

Similarly other RPC URL"s. due to which, the following error message is displayed while deploying our contract via Remix.

creation of AddressResolver errored: Error: JsonRpcEngine: Response has no error or result for request:

[Solved] XDC Faucet throws - Internal Server error

Unable to get XDC Faucet through faucet.apothem.network it throws the following error.

[WIP] HeadTracker is not capturing few blocks in Apothem / Mainnet

Lokesh — Mon, 25 Sep 2023 07:54:09 +0000

We are witnessing this issues recently, when we setup Plugin2.0.

This issues were not occuring before, but recently. To check the issues, we have executed the Plugin2.0 in "Polygon" and also in "XDC Mainnet". Logs for both the execution is captured below.

Actual issue?

In Plugin, when we configure more than 4 jobs, the execution is failed and resulting the following error

"2023-09-25T12:48:34.707+0530 [ERROR] Error in new head subscription, unsubscribed headtracker/head_listener.go:67 err=websocket: close 1000 (normal) evmChainID=50 logger=EVM.HeadTracker.HeadListener stacktrace=github.com/GoPlugin/pluginV2/core/chains/evm/headtracker.(*headListener).ListenForNewHeads"

When we execute the same against "Polygon" chain, it runs without any issues.

Log ::::

Log shows that, "headtracker is missing" a block, due to which we face "RPC node is not reachable" and it is on & off and instable.

Head & Block logs for Polygon: https://notepad.pw/g50JXvp3RIn1PNfe2Tea

For XDC : https://notepad.pw/o7VtAjvuS4dFtN0YdLyd

You may see the difference in XDC Log, where the blocks are missing.

Note: We have tested the available RPC from "https://chainlist.org/" for Apothem & Mainnet and the results are same.

Let us know if you need some more informations to debug.

Kindly review and let us know the possible solutions.

[WIP] Hardhat: Upgradeable Proxy support for XDC

Lokesh — Tue, 12 Sep 2023 15:27:36 +0000

Unable to setup upgradeable proxy contract using Hardhat features. Setup is working fine with other evm compatible blockchain.

Can we look into this?

How to replicate this issue?

const { ethers, upgrades } = require("hardhat");

async function main() {
  //   const gas = await ethers.provider.getGasPrice();
  const CLCStakePool = await ethers.getContractFactory("CLCStakePool");
  console.log("Deploying stakePool...");
  const v1contract = await upgrades.deployProxy(CLCStakePool,[]);
  await v1contract.waitForDeployment();
  console.log("Contract deployed to:", await v1contract.getAddress());
}

main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

use this deployment script, replace the contract with your own contract.

Expected results : it should deploy the contract fine and provide the contract address

Actual Results : Erroring out with "ProviderError: too many arguments, want at most 1"

[Informative]Exploring the Convergence of AI and Decentralized Oracles!

Exploring the Convergence of AI and Decentralized Oracles! 🌐 @plugin

In the rapidly evolving landscape of technology, the fusion of Artificial Intelligence (AI) and Decentralized Oracles has emerged as a game-changing phenomenon. AI has completely changed how we gather, process, and analyze data, empowering us to make decisions with unmatched accuracy. On the other side, a new era of openness and trust in data sources for blockchain applications has been ushered in by Decentralized Oracles.

The potential is endless when these two potent technologies combine . AI can access real-world data by utilizing the decentralized, tamper-proof nature of oracles, ensuring the accuracy and dependability of data utilized in decision-making processes. This collaboration opens the door for more accurate and secure predictive analytics, better contracts, and data-driven insights..

Think about AI-powered platforms that can seamlessly access decentralized oracles to gather information on supply chain metrics, market trends, and even weather patterns to generate data-driven forecasts in real time. Industries like finance, healthcare, logistics, and others could be redefined as a result of this convergence.

It's critical to promote cooperation between AI experts and blockchain engineers as we traverse this crucial juncture. By working together, we can solve issues like data privacy and security while ensuring the ethical and responsible use of this technology pairing.

At Plugin, we're actively exploring and building compelling use cases that harness the immense potential of AI, unleashing its capabilities alongside the transformative force of Decentralized Oracles. 🚀

But the same contract throws error in XDC Network, resulting( JSON-RPC ) issues with XDCPay, since the token value is 0.

Issue Details: Token minted not showing in XDCPay, please see the snapshot

where as it is showing in Metamask correctly

Actual Results: Token minted is not showing up in XDCPay but the tXn has the token value - Link here

[Solved]Invalid address issue: While submitting Txn from XDCPay wallet

Lokesh — Sat, 03 Dec 2022 18:59:10 +0000

@blocksscanio Team - From today morning, we are facing an issue while submitting the transaction from XDCPay.. It seems, it is prefixing the XDC instead of 0x in wallet address / contract address.

Any update made recently Or should we use https://erpc.xinfin.network in XDCPay to arrest this?

please assist.

onError Error: invalid address (argument="address", value="xdc117c691d76c1d9c68e3709a87f7d496097f2b56f", code=INVALID_ARGUMENT, version=address/5.7.0)

Note: the same logic was working fine till yesterday.

[Solved]XDCPay is not being recognized in Ethereum Remix --

Lokesh — Fri, 02 Dec 2022 07:12:19 +0000

I tried to connect https://remix.etherum.org with XDCPay, and got the below error while selecting "Inject Web3 Provider"

"No injected provider found. Make sure your provider (e.g. MetaMask) is active and running (when recently activated you may have to reload the page)."

It was working fine a month before, right after that we are facing this issue in all the browsers.

Any changes made recently?, which broken this connectivity?

Note: Xinin remix has some issues and it is keep crashing from today morning.
