# NFT and Messi By [ElisasAraya](https://paragraph.com/@elisasaraya) ยท 2024-04-04 messi, nft --- An NFT is like having a collectible Lionel Messi figurine, but with something very special: that figurine is signed by Messi. Imagine that in the world of figurines, there are thousands of them of Messi, but yours has his original signature and there is no other like it in the whole world. Even if your friends have many Messi figurines, none of them will be like yours because only yours has that unique and special signature. In the digital world, an NFT works in a similar way. For example, someone could create a digital art image, a gif, or even a short video of Messi scoring the most spectacular goal of his career. This file becomes an NFT when a sort of unique "digital signature" is added to it that cannot be copied, making that image or video unique in the digital world. Although other people may see or even have a copy of that image or video, only you will have the NFT, that is, the digitally "signed" version that is recognized as unique and original. Just as the signed Messi figurine would be the treasure of any collection, the NFT becomes a valuable and coveted digital collectible. **Does it have real value?** [Show me the money](https://www.youtube.com/watch?v=bRl_sBg6GX8&ab_channel=SamGor) The actual value of an NFT in the market can vary greatly and depends on several factors, similar to what happens with traditional works of art. Here are some of the factors that can influence its value: Rarity and Uniqueness: The more unique or rare the NFT, generally, the greater its value. The Creator Person: NFTs created by famous and recognized artists or developers can have a much higher value because of their association with that person. It is like the difference between an Argentina soccer jersey and one signed by Messi: the signature adds considerable value. Ownership History: NFTs that have been owned by celebrities or influential people can increase in value simply because of their ownership history. Utility: Some NFTs offer additional benefits beyond being digital collectibles, such as access to exclusive events, rights to use them in games or applications, or even shares in projects. These benefits can increase their value. Market Demand: Like any other market, the NFT market is governed by supply and demand (as is the case with [Yerba Mate](https://youtu.be/WRgho6UiWGg?si=Es500zcIIz9gRsok) and [Lettuce](https://youtu.be/2VPq0UuXsF0?si=6Xo-wjE6dPfn9AYW) in Argentina). An FTN can increase significantly in value if there are many people interested in buying it and few units available. Sentiment and Personal Connection: The value of an NFT can also be subjective, based on what the buyer is willing to pay for it. Some people may value an NFT more for personal, emotional reasons, or for the simple desire to support a specific artist or project. Having said all this, the NFT market is volatile and its value can fluctuate rapidly so an NFT that is very valuable today may not be valuable tomorrow, and the other way round. ### Create an NFT from scratch First of all patience, patience because Rome was not done in one day. First of all read documentation, real documentation on [GitHub](https://mirror.xyz/0xB534e2Df315dB1772af193b1491BD91BE4cf635E/TF-BmobfFUrjWYHdiC8qlYWdLqy0o0TFDfVLg5y13M4#:~:text=Primero%20antes%20que,Relaja%20y%20respira.) about the different currencies and try, if you are going to look for a video, make sure that they are current, from the year you are trying to do it because if you are going to see one from the year 2021 it is no longer useful. Second, I repeat, read real documentation, it is not useful to copy and paste, try to understand what you are going to do and why, what for. Relax and breathe. After familiarizing yourself with the documentation and understanding the basic concepts, it's time to get started with The Code: Select your Platform: You are going to have to decide on which platform you are going to create your NFT. Ethereum is one of the most popular(and expensive) and widely used(and expensive) options, but there are also other blockchains that support the creation of NFTs, such as [Binance Smart Chain,](https://www.binance.com/es/square/post/448884) [Solana](https://solana.com/es/developers/nfts), and [Tezos](https://tezos.art/), among others. Set up your development environment: Set up your development environment to start throwing code. This may include installing tools such as [Metamask](https://metamask.io/), [Remix](https://remix-project.org/), or [Truffle,](https://archive.trufflesuite.com/docs/) depending on the platform you choose and your personal preferences. Write your Code: Now you need to start using the knowledge gained from the documentation to write your own [smart contract](https://blog.lemontech.com/smart-contracts/) code. Try to understand each line of code and how it affects the operation of your NFT, it's trial and error. More mistakes than anything else. Test your Contract: Before deploying your contract on the main network, it is essential to test it on a test network such as [Goerli](https://github.com/eth-clients/goerli) or [Sepolia](https://github.com/eth-clients/sepolia) (for Ethereum) (if you searched for info before 2022 they will tell you [Ropsten](https://github.com/ethereum/ropsten) but it died) or [Testnet](https://github.com/binance/binance-spot-api-docs/tree/master/testnet) (for other blockchains). This will allow you to identify and fix bugs before they affect your NFT in production. To deploy your NFT: Once you are sure that your contract is working as expected, you will be able to deploy it on the main network and [create your own NFT](https://medium.com/@dekachi17/tutorial-de-implantaci%C3%B3n-de-contratos-nft-916e44449be). A simple explanation of how to create an NFT using Mumbai and Thirdweb: **1) Log in to** [**Thirdweb**](https://thirdweb.com/) ![](https://storage.googleapis.com/papyrus_images/ddc5a91e8055e4346451e65e7d199a44.png) Read the documentation! And well, let's get started ![](https://storage.googleapis.com/papyrus_images/8c79640cb30a607af1bffd2a93e943e1.png) You will have to connect your wallet ![](https://storage.googleapis.com/papyrus_images/8edf03c90ac4571ad1eac9c578281192.png) In my case I did it with MetaMask ![](https://storage.googleapis.com/papyrus_images/004cc19bdf8573d31313555ad272a1a6.png) You are logged in, make sure you are logged in, then go to Contracts ![](https://storage.googleapis.com/papyrus_images/d153fc69019823e5cc98faec5da50c0a.png) This way you see the page, the popular and below there is NFT Choose an NFT Standard: Your token can be: [ERC-20](https://ethereum.org/es/developers/docs/standards/tokens/erc-20/), [ERC-721](https://ethereum.org/es/developers/docs/standards/tokens/erc-721/) or [ERC-1155](https://ethereum.org/es/developers/docs/standards/tokens/erc-1155/). Each standard has its own specific features and use cases. ![](https://storage.googleapis.com/papyrus_images/8fc3289b43d455c22c746c72f6e6223d.png) Token Standard ![](https://storage.googleapis.com/papyrus_images/803afcd0db91000573c9d1b2a8e61f72.png) I will choose 721 ERC-721 tokens are non-fungible tokens (NFT), which means that each token is unique and can represent a unique digital asset, such as a piece of artwork, a photograph or a collectible. With ERC-721, you can assign your photo to a single token and ensure that it is unique on the Thirdweb network. ![](https://storage.googleapis.com/papyrus_images/bfcbb6bc4fdef4c283e92c001f4f9d65.png) Important details The name, a token (you saw that web3 people like crazy tokens, this is random eh), the description, your wallet with the public key, percentage and below you need the Mumbai network (this took me a couple of hours to connect). Test Tokens: You will be able to request test tokens on the [polygon faucet page](https://faucet.polygon.technology/). This can take a while, check the discord, close the discord because sometimes it slows everything down (it also took another couple of hours). ![](https://storage.googleapis.com/papyrus_images/234bc29f561fb5caba63a1924146c30a.png) Deployment status In every moment you will be asked for permission so in your wallet you have to give ACCEPT, OK, CONNECT and many times it takes a while and sometimes it doesn't even appear to connect so there is always the reliable F5 and start all over again. Disconnect Wallet and everything and start from scratch again. ![](https://storage.googleapis.com/papyrus_images/d0ed4a3b5d00f25535813497ec2b9453.png) Finally Bebecita Webcera3 After almost 48 hours I was able to create 3 NFT with ERC-20, ERC-721 and ERC-1155. I leave my little monsters created very proudly after a couple of tears: ![](https://storage.googleapis.com/papyrus_images/b9cf26552808256dd81961ad2bdc1f45.png) NFT proudly And it did give me an error: * Wallet error. * Connection error. * Transaction error. * Error Error **And after creating them, I managed to create the one and only:** ![](https://storage.googleapis.com/papyrus_images/5cc9a89de06e679869169e688269db1c.png) Messi NFT by Cascieri Use this standard: [ ![](https://thirdweb.com/api/og/publishedContract?description=Create+collection+of+unique+NFTs.&extension=ERC721&extension=ERC721Burnable&extension=ERC721Supply&extension=ERC721Enumerable&extension=ERC721Mintable&extension=ERC721BatchMintable&extension=ERC721SignatureMintV1&extension=ERC721UpdatableMetadata&extension=Royalty&extension=PlatformFee&extension=PrimarySale&extension=Permissions&extension=PermissionsEnumerable&extension=ContractMetadata&extension=Ownable&extension=Gasless&extension=ERC721UpdatableMetadata&extension=Fallback&license=MIT&license=Apache-2.0&logo=ipfs%3A%2F%2FQmWARxASHf4UcWkwxTUDJxAXVDUG5STu5yBePJg35GzqjZ%2Fnft-collection.png&name=NFT+Collection&publishdate=Dec+18%2C+2023&publisher=0xdd...024&publisheravatar=https%3A%2F%2Fd391b93f5f62d9c15f67142e43841acc.ipfscdn.io%2Fipfs%2Fbafybeihoi2a4glq3tznlcs6bgyfrb3w63o25ulld4cfewda2qmxj32rx4y%2F0.png&version=5.0.1&og_version=0.1.0) https://thirdweb.com NFT Collection - ERC721 | Published Smart Contract -------------------------------------------------- Create collection of unique NFTs..
