[Proposal] Implementation of smart contract ownership verification feature on XDC

qwerty389 — Tue, 27 Feb 2024 11:12:06 +0000

We are requested by XDC team to further elaborate on our proposed certification and verification of smart contract on XDC that received positive feedback. Here are the details.

Implementation Process

We need to implement our solution on XDC block explorer so that XDC users could easily ascertain if a contract is verified. For example, view our live demo for Sepolia testnet. When you click on the green icon beside the contract address, you'd be able to view the ownership details of the contract such as,

Individual or Organization name
Website
Email address (optional)
And more...

This information shall be verified by us prior to issuance of digital certificate. In order to view this data, we need to integrate our certification and verification code on XDC block explorer. We envisage working together with BlocksScan team to perform this where,

We will provide the customized source code and BlocksScan team will implement the code on the explorer. Here, we're assuming XDC explorer is based on Blockscout code base. If not, we shall work with the team to provide a customized code specifically for their explorer platform. We shall bear the cost of this customization.
We shall both perform the necessary testing.

Once the implementation is complete, we shall work with XDC team to provide free digital certificates to every contract on XDC for the first year. Plus, we shall subsidize the gas fees (up an agreed max cap) on contract deployment for contracts that are installed with our digital certificates.

[Proposal] Certify & Verify Smart Contracts on XDC

qwerty389 — Mon, 30 Oct 2023 00:42:56 +0000

Goal

To authenticate and verify smart contract ownership on XDC blockchain via digital certificates to fight scams, at no cost to XDC. Here's a video intro -> https://youtu.be/5Pf4ZUyiQvo

4 PROBLEMS: Smart Contracts Ownership Is Not Verified

Anyone can deploy a contract on any chain without verification of ownership. E.g., John can deploy an ERC20 contract named USDC even though he’s not from Circle.
Digital artists are having their NFT art counterfeited and buyers have no way to verify which is real or fake.
Current verification method only verifies contract source code. This means, a scammer can also have their source code verified.
Scammers can create fake smart contracts that look legitimate and are only differentiated by their contract addresses which are hard to tell apart.
Often these fraudulent contracts are listed on phishing websites that also look like the original.
Case in point is the BAYC scam

1 SOLUTION: Authenticate and Verify Contracts Ownership With Ztamp

Ztamp issues digital certificates for smart contracts deployed on any blockchains where the certificates ascertain who are the owners of the contracts.
Each smart contract ownership can also be verified on block explorer, similar to Twitter blue checkmark (not to be confused with source code verification). Here's a video demo - https://youtu.be/5Pf4ZUyiQvo
NFT buyers can identify which NFT is original and which is a counterfeit just by looking at the “verified” checkmark on smart contract that issued the NFT.

How it Works

Go and install our Chrome extension at https://chrome.google.com/webstore/detail/ztamp-contract-verifier/gkcoamipecajkfinfppgebiekmmmljna
Then, go to https://sepolia.etherscan.io/address/0x250D37b01Bd69ec0693f9385EC511510D4E045bF to view the contract's verified checkmark and click on the checkmark to view the owner's details of the contract.
Contract developer's website is also verified.

Our Special Offer to XDC

We wish to implement our contract verification module on your block explorer so that your users don't have to install any browser extension to know if a smart contract on XDC can be trusted. And we're willing to work with XDC for free, meaning we're not requesting for any grant money.

USE CASES

Smart contracts for any tokens
Smart contracts for DeFi
Smart contracts for NFT digital art
Smart contracts for NFT marketplaces
Smart contracts for Web3 games
Smart contracts for coupons
Smart contract for DIDs
Smart contracts for certificates – academic, deeds, trusts, etc
Basically, any smart contracts that don’t want to be labelled as a scam!

PROPOSED MILESTONES

Please view our detailed milestones at https://drive.google.com/file/d/1wxTZEgVAV_qNV09HaRnliwXBIojG1P7R
We're offering 200 digital certificates for free to anyone who wishes to authenticate and verify their smart contracts on XDC.
We're not asking for any grant payments from XDC.

[Solved]Can't deploy Remix contract on Apothem

I still can't deploy a contract using Remix. It's been 30 minutes and I'm still waiting.
