Problem Statement

What is AddreNFTy?AddreNFTy is an innovative protocol poised to redefine how developers perceive and employ Ethereum contract addresses. Fundamentally, think of AddreNFTy as the equivalent of buying a domain name in the Web2 world, but tailored for smart contracts in Web3. With AddreNFTy, not only can you reserve a contract address, but you also have the option to deploy a contract on it or mint it for potential future sale.##How Does It Work? Traditionally, when a contract is deployed, its address depends on both the nonce of the sender and the sender's address. While accurate, this only scratches the surface. There's an alternative:CREATE2. WithCREATE2, the contract address is derived from the sender's address, the nonce, and a unique salt. However, AddreNFTy introduces an even more streamlined method—akin to aCREATE3—where the contract's address is determined solely by the sender's address (which, in this case, is AddreNFTy) and the salt. Here, the salt encapsulated in the NFT serves a pivotal role. The NFT owner can utilize this salt to deploy a contract to a pre-defined address. To safeguard against front-run attacks, the salt includes the minter's address. Once a contract is deployed to the address denoted by the NFT, the NFT becomes "soulbounded" to that contract.In Summary:Deterministic Address Generation: Mint an NFT using a specific salt. This encapsulates the designated contract address for future deployment.Mint, List, or Purchase: Have the liberty to list your NFT for sale, presenting it to potential buyers.Protocol Bounties: Set a bounty on a particular address, incentivizing others to discover the right salt for you.Deployment: Deploy a contract to the NFT's represented address. Upon successful deployment, the NFT becomes soulbounded, solidifying its union with the contract.

Solution

The creation of AddreNFTy involved a blend of technologies and innovative approaches. Here's a breakdown of the tools we used, how they interconnect:Foundry: At the heart of AddreNFTy lies our suite of smart contracts. For their development, I used Foundry. Solmate: For the NFT and CREATE3 implementation using create3, we've crafted a deterministic contract address generation system. Sveltekit: Known for its minimalistic yet powerful approach, SvelteKit allowed us to develop a responsive, intuitive, and lightweight frontend. Viem: we use it in the frontend to interact with the deployed contracts. Service workers: we leverage the mining process of a salt in the navigator service workers. TheGraph: Marketplace & Bounties. For managing our NFT marketplace and tracking bounties, we've tapped into the power of TheGraph
