Hello, I have been professionally writing Solidity (and occasionally grabbing hackathon prizes) for the past 4 years. When you say cross-chain deployment: do you just need the same contract deployed to both Ethereum and Gnosis Chain? Or do you need more advanced stuff like making the 2 contracts communicate with each other (yes it's possible)? In both cases, I am confident I can take care of this task in a satisfactory way. Et petit bonus: je parle français.

Hi, as a senior blockchain engineer, I can build the project successfully very shortly. Should I build your smart contract and integrate it? I have rich experience with the dApp development such as the smart contract, NFT marketplace, and so on. So I am familiar with the erc20, erc721, erc1155, etc. Regarding my last NFT marketplace, I built the NFT smart contract using solidity and deployed it using hardhat, Remix, and Truffle. And integrated the smart contract with the front end side using web3, and etherjs. So I can fix the problem successfully in a short period. If you don't mind my skills and experience, I can start it on today. Best Regards.

EXPERT in blockchain development. I can fork the Uniswap Dex Contract and customize with your requirement and will deploy on Ethereum mainnet and Gnosis chain. Also, I'm very familiar with the Web3 integration, will build the Dex UI to let users swap ERC20 tokens. I think you put importance on the Walletness functionality, so I propose the Email wallet feature and gasless meta transaction with Openzeppelin meta transaction and defender protocol. Let's discuss this in detail over the chat. Looking forward to hearing from you. Best regards, Gediminas V.
