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.
