    ERC20 Token 6 días left

    Hi, Freelancers. I have a simple task for you. ## Problem Deploy an ERC-20 Stable Coin on the Rinkeby Test Network with the following protocols in Solidity: 1. It should be pegged to the Japanese Yen. 2. The token should have limited supply. 3. The token should burn half its supply in 2 days (or any period) Include a small paragraph explanining your token and how it will function somewhere in your code // commented out is fine, Readme file is fine too! The content and data used is your choice. You will be graded on: - Readability of your Solidity code - Simplicity in implementation - Creativity in code structure ## Extra Credit Incorporate Polygon in any way. If anyone can do this, don't hesitate. Thanks.

    Hello we'd like to use Manifold studio () to lazy mint a custom contract for a collection of ~400 jpgs and gifs for an art based NFT collection. We don't want to pay gas fees to upload each item so lazy minting would probably be ideal for this project ( although we'd like your input) Manifold doesn't currently have a lazy minting option but it can be implemented via an extension. We need help adding that extension to our project. Let us know if you're interested and we'll discuss further. Thanks
