A VERO always begins with two things - a real object and a 3D model. The real object needs to be uniquely identified so that a singular object is identifiable both in a local sense, e.g., in museum collections, and in a global sense, e.g., UUID. There must not be any ambiguity around which item is the real world analog for the digital representation. That real world object must also have an accurate 3D model and exist in perpetuity in the real world, otherwise the VERO will be subject to immediate revocation. The reputation and assurances of continued care from the repositories of the real objects, like museums, builds trust amongst collectors that their VEROs will be there indefinitely. The good thing is that that already aligns with the mission of museums that house our history: be it biological, artistic, or historical. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/61187bb40e8af33963f012e4/1629018102726/VERO+NFT+Flow.jpg Technical Details - … How do I create a VERO? A VERO is an NFT that only becomes a true VERO once all of the requirements of the specification are met and the VERO Admin Account creates a transaction on the Ethereum blockchain approving the status. Part of the reason why a VERO should be more collectible than a standard NFT is that a VERO corresponds with a 3D model that is assured to be tied to a unique real world object, where the original object is stored in perpetuity, otherwise the associated NFT stops being a VERO. This symbiotic mechanism makes minting VEROs especially advantageous to museums, which already store real items of historic value and want to create 3D models, and appealing to collectors, who appreciate rare, unique items to own. Ensuring that an NFT can be created that enforces the requirements of a VERO cannot be done automatically right now. There is not a global inventory of real world items that can be leveraged to confirm that a real world equivalent exists. Malicious actors can flood the market with false VEROs undermining the collectability and trust in the concept itself. That is where the VERO smart contract and the VERO Admin Account on the Ethereum blockchain ensure greater confidence in this type of NFT. Once they decide to sell a virtual equivalent of an object as a VERO, the real world object owner, most likely an authorized delegate of a museum where the object is permanently stored, needs to ensure that their object is ready to become a VERO. The checklist below defines all of the special attributes that a real object must have in order to become a VERO. https://www.vero-nft.org/how-to-create-a-vero daily 0.75 2021-08-25 https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611e568e1197c64ea55401ba/1629378228951/mew-wallet-home.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611aea21cd0917436df7e0aa/1629153844985/toy-truck.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611e54b18f6c5564662255d5/1629378180374/mew-wallet-connect.png How to Create a VERO - Make it stand out Go to the MEW home page and click on Access My Wallet. From this new page, you’ll want to connect to your MetaMask wallet, so click on the MEW CX option. After confirming access to your wallet, which will include granting access to your test Ethereum account from MetaMask to MEW, you will be taken to the MEW wallet dashboard. At this point it is very important to confirm that you are operating on the Rinkeby Test Network (RIN) and not the Ethereum mainnet (ETH). Make sure your account balance is in RIN and the network specified is “Web3 Provider(RIN)”. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611ed7406edcb62a95c50809/1629411213526/etherscan-contract.png How to Create a VERO - Open in a new browser tab, the VERO smart contract page on Etherscan for the Rinkeby Test Network. Click on the Contract tab, if the above link does not take you there directly. Then scroll down to the Contract ABI section. Copy the value to the clipboard by clicking the copy icon. Go back to the Interact with Contract page in MEW and paste the contract ABI code in the ABI/JSON Interface field. Enter the contract address, 0x07ffe55d6127120145b9aaef4649678fe21ad4cc, in the Contract Address field. Click the Continue button to begin to interact with the contract functions. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611da87b4d9a5338a5462086/1629333636743/pinata-toy-truck-model.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/6122d0911b928c0b6aff80b7/1629671582174/mew-specify-contract.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/6121332e27006e650ccbb3bf/1629565774788/gas-create-estimate.png How to Create a VERO - Once approved, the transaction is sent off to the network. You can follow along in MetaMask under the Activities tab for your account until the transaction has completed processing on the network. Conveniently, you can view prior transactions that created a PENDING VERO from Ethereum blockchain explorers like Etherscan. Looking at prior transactions against the VERO smart contract will give you a sense of the gas needed to mint the NFT. With the gas used, you can go to the ETH Gas Station and retrieve the estimated transaction costs. From using test networks, minting a PENDING VERO will use ~333,000 gas and cost around $40. NOTE: Both of these values are bound to fluctuate, so check for yourself prior to minting to get a better idea. When the transaction has completed, you will have created an honest to goodness (test) NFT! Not quite a VERO yet, but it’s close. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/61213a5aba87964dd7be2000/1629594023174/gas-approve-estimate.png How to Create a VERO - Prior to a decision being made and the status changed, some Ether should be transferred to the VERO Admin Account, 0x77deC79EdB77a22ddC8272e45988599FCFAb32FF. Although this is not a money making endeavor for the VERO authors, we do not want to pay out-of-pocket to process transactions on the Ethereum blockchain to change the VERO status. From using test networks, approving / rejecting a VERO will use ~55,000 gas and cost around $6. Any excess Ether that was transferred to the VERO Admin Account and does not need to be kept there for future gas charges will be transferred back to the original minters. NOTE: Both of these values are bound to fluctuate, so check for yourself prior to requesting approval to get a better idea. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611ed9fc0b518621073e60c5/1629417163362/mew-interact-contract.png How to Create a VERO - Adjust the dropdown to the right of the contract address to the “createAsPending” contract function, which as the name suggests creates an NFT that is in a PENDING VERO status. Take the IPFS token metadata URI, ipfs://QmU66p2V1QPJrbDwtAGNhgH85mkxcwqDKUxeDc8ZyQpaKX, that you had created in the earlier section and paste it into the _tokenURI field. No need to specify Ether as the smart contract does not require Ether to mint a new token. You will have to be pay gas charges, though, but remember that this is a test network so it's not real Ether. Click on the Write button to initiate the transaction. MetaMask will open up with a request to approve the gas needed to fulfill this transaction on the Rinkeby Test Network, which will be the same process when done for real. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/6122cfc22ed25f4699e6bd03/1629671370971/pinata-toy-truck-token-json.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/6121457827006e650ccc8571/1629583161179/opensea-home.png How to Create a VERO - Make it stand out Although you can sell your VERO on any NFT marketplace or negotiate the sell yourself, we will use OpenSea, which is the most popular NFT marketplace and has native support for 3D models on their NFT pages. Also for testing purposes, OpenSea integrates with the Rinkeby Test Network, which makes trying out the whole process first much easier. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/612184f958642907f49c5f04/1629586690968/opensea-vero-posting.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611c6c3f392ae006b088b961/1629252701876/pinata-home.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/612130f89b28c023040d5fd4/1629565379319/etherscan-vero-status.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/612177ec9a97d543dadf231e/1629583433878/opensea-list-vero.png How to Create a VERO - Now that you’re on the Sell page, you have a lot of different options that give you flexibility (set price sells, highest bid auctions, and bundling multiple items together). Explore and see which options work best for you, even though we’re just testing right now. Once you get your VERO sell options all set up, click on the “Post your listing >” button. This will open up the MetaMask extension again to give authorization to sign the request using your Ethereum account. When you approve, OpenSea will show the processing stages to get the VERO posted. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611c6dd3270bdd2b105f4060/1629253083765/pinata-toy-truck.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/612174b39a97d543dadeee63/1629582532069/opensea-profile.png How to Create a VERO - Click the profile icon on the OpenSea home page at the top right and select “My Profile”. This will open the MetaMask Chrome extension to connect your MetaMask test account wallet to OpenSea, so it can access all of your NFTs. We know your wallet includes at least one VERO from above. This will be the same process you followed with MEW earlier. Click on the VERO you want to put up for sell on OpenSea Testnets, then click the “Sell” button on the top right of the page. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/6122cf48e319162f60bf557c/1629671267867/pinata-toy-truck-object-json.png How to Create a VERO - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611b21b63ac914066029b696/1629168063971/toy-truck-3d-vero.png How to Create a VERO - What you’ll need to create an NFT that will become a VERO To create an NFT that can eventually become a VERO for testing, you need the token URI (you just created it above!), the VERO smart contract address on the Rinkeby network, and some Ether in your test account tank. We’ll be using a web-based client-side application to interface with an Ethereum network called MEW (MyEtherWallet), although an older version as the newer one has an annoying bug, along with the MetaMask browser extension to create the NFT against the VERO smart contract in your browser. No programs needed to install or user profiles created for any of this. https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611da99c3390496f0dd866ba/1631371154955/metamask-test-account.png How to Create a VERO - The first step to creating a VERO is getting set up with an Ethereum account https://static1.squarespace.com/static/610e96e82d4cdc6cebf573ec/t/611ae0815871a965bf8a810b/1629162556043/toy-truck-3d.png How to Create a VERO - My first (test) VERO is a toy truck My first (test) VERO is a toy truck
