Grant Application: TxShield - Transaction Safety Simulator
Project Name: TxShield
MVP Official Docs: github.com/HoodClock/OfficialDocs
MVP Demo: safe-tx-simulator.vercel.app

Overview
TxShield is a transaction simulator and a detection tool for the contracts as well that prevents failed transactions, gas waste, and honeypot scams by previewing risks before execution. Built with Ethers.js and Next.js, it targets 21M+ wallets users and plans to expand to Polkadot’s EVM

Thanks for the updated application @HoodClock. Can you explain more about how the honeypot contract works in practice?

[HoodClock]

Hi @keeganquigley, Thanks for the follow up, The honeypot Contract looks like a normal smart contract on the outer shell but deep in this its a trick to block the user funds. It lets user send amount and promises a reward or sometime return with extra based on the scammer hook but when a user try to withdraw their funds the internal logic of smart contract wont let user do that instead it traps the funds.
I have made the custom honeypot contract just for testing using solidity here is the link [https://github.com/HoodClock/OfficialDocs.git]

So to demonstrate the honeypot contract i have made the simple smart contract that pretends to allow withdrawals. But in reality, a fallback function force-ably revert.
Since this is one of the most common honeypot tricks, I’m also exploring ways to detect more advanced types as I continue building the Beta version.

Thanks for the explanation @HoodClock this sounds very similar to Token Sniffer for Solana. Let me clarify though that the W3F grants program is focused solely on the Polkadot ecosystem. Therefore there are many deliverables we wouldn't be able to fund, such as:

• 1.3 "Extend Ethers.js support to Polygon & Optimism (Sepolia tested)"
• 2.0b "Tutorial update for Polygon support".

For further consideration, I would recommend re-purposing the application to focus on Polkadot, with a possible Asset Hub (PVM) deployment in addition to Moonbeam (which are planned to launch in September).

Hi Keegan, Thanks for the clarification and follow-up. After some thought, I believe the core vision of TxShield aligns more with broader EVM compatibility, where the tooling can serve users across chains like Ethereum, Polygon, and Optimism. While Polkadot is a strong ecosystem, narrowing the scope exclusively to it might limit the platform’s long-term potential. I truly appreciate the opportunity, but for now, I’d prefer to stay aligned with the broader EVM landscape. Thanks again for your time and support! Best, Moiz
