📜 README: T1-DApps Community Proposals

Welcome to the T1-DApps Community Repo! 🎉

T1 is building the first interoperability rollup, enabling real-time proof verification across Ethereum and rollups. Our goal is to restore composability in the fragmented Ethereum ecosystem, making cross-chain dApps seamless and efficient.

This repository serves as an open forum for developers, researchers, and community members to propose new decentralized applications that leverage T1’s unique capabilities.

🛠 How to Contribute

We encourage you to submit your dApp ideas as GitHub issues in this repository. Follow the structured template below to ensure clarity and completeness.

📌 Submission Requirements (GitHub Issues)

When opening an issue, please copy and paste the following template and fill in your responses:

Issue template

🏷 Title: [Your dApp Name]

(A short, descriptive name for your application idea.)

🔍 Problem Statement

What problem does your dApp solve? Why does this need to exist in the Ethereum ecosystem?

🚀 How T1 Enables This

Explain how T1’s interoperability rollup, real-time proofs, and unique architecture make your dApp feasible or significantly better than current solutions.

🏗 Technical Architecture

• Primary Contracts: (Briefly describe the smart contracts required.)
• Cross-Rollup Interactions: (Does this dApp involve multiple rollups? If so, how?)
• T1-Specific Features: (Does it require instant finality, secure off-chain execution, or encrypted mempools?)

🔄 User Flow

Describe the user journey step by step, from initiation to final settlement.

📌 Dependencies

Does your dApp require integration with existing protocols, liquidity sources, or standards (e.g., ERC-7683, ERC-4337, etc.)?

📈 Potential Use Cases

How would developers, users, or projects benefit from this dApp?

🎯 Target Audience

Who is most likely to use or build on this dApp (e.g., DeFi traders, NFT collectors, gaming developers, institutional users)?

💡 Additional Notes

Any extra context, inspiration, or references to related projects.

Example submission

🏷 Title: T1 Cross-Chain Auction House

🔍 Problem Statement

Current NFT auctions are siloed to a single rollup or Ethereum L1, making price discovery and liquidity fragmented.

🚀 How T1 Enables This

T1 allows instant cross-rollup finality. Users on Arbitrum, Optimism, or Base can bid on NFTs listed on other chains, knowing settlement is guaranteed without relying on centralized bridges.

🏗 Technical Architecture

• Auction smart contract on Ethereum L1 to manage listings.
• Bidding contracts on rollups interact with the main auction contract via T1’s real-time proofs.
• Escrow mechanism using ERC-7683 ensures winning bids settle instantly.

🔄 User Flow

1. Seller lists an NFT on Ethereum L1.
2. Bidders place offers on any rollup (Optimism, Arbitrum, Base).
3. T1 verifies bids in real-time, preventing bid sniping.
4. The highest bid is finalized across chains, and ownership transfers automatically.

📌 Dependencies

• ERC-721/1155 for NFTs
• ERC-7683 for cross-chain settlements

📈 Potential Use Cases

• Cross-chain NFT marketplaces
• High-value asset auctions
• Composable DeFi derivatives

🎯 Target Audience

NFT collectors, DeFi traders, auction platforms

💡 Additional Notes

Inspired by Sudoswap, Seaport, and Cross-Chain NFT Bridge discussions.
