How do I create an NvirWorld account?

Follow these steps to create an account and start buying or selling NFTs on NvirWorld.

1) Digital Currency (ETH)
You need to get ETH, the cryptocurrency of the Ethereum blockchain, from a cryptocurrency exchange like Coinbase. ETH is needed in order to mint and buy an NFT as well as for gas fees to complete transactions.
Learn more about gas fees and all technical details of gas here: Jeff Coleman’s Stack Exchange post.

Once you have ETH, you need a crypto wallet.

2) Crypto Wallet
With a crypto wallet, such as MetaMask, you can store your ETH and make transactions on the Ethereum blockchain. When creating a crypto wallet for the first time a unique wallet address will be generated and you will use this address to complete transactions.



Watch our video to learn how to install a crypto wallet and connect it with NvirWorld.
All transactions connected to your wallet address can be found on
etherscan.io. It's always a good idea to check Etherscan after completing each transaction.

Why do you need a wallet before buying and selling on NvirWorld?

NvirWorld itself is another tool you use to interact with the blockchain. We never take possession of your assets or store your NFTs. Instead, we provide a system for peer to peer exchanges. Since you’ll be using NvirWorld to interact directly with others on the blockchain, you’ll need a wallet to help you turn your actions in the browser into transactions on the blockchain. Check compatible wallets with NvirWorld.

Now that you have a crypto wallet installed, you can connect your wallet address to NvirWorld.

3) NvirWorld

What is a crypto wallet?

A crypto wallet is a software program that stores public and/or private keys for cryptocurrency transactions and Non-Fungible Tokens (NFTs).



Watch our video to learn how to install a crypto wallet and connect it with NvirWorld.

How do crypto wallets work?

When you download a crypto wallet, you are given two 42-character keys, a public key (wallet address), and a private key.

While the public key is comparable to a username, a private key is like a password. When asked for your wallet address, copy and paste your public address.
It's essential to never reveal your private key to others.

Crypto wallets and NvirWorld

Decentralized applications, or "Dapps", work differently from traditional websites like eBay. When you purchase an NFT on NvirWorld, there is no exchange or coins or currency, and the transaction made is recorded on the blockchain. This, in turn, will result in a change in the balance of the sender and receiver's cryptocurrency wallet as the funds go straight from your crypto wallet to the seller's.

Security: keep your funds safe

Understanding risk is the key to successfully navigating the brave new world of crypto and NFTs. As NvirWorld never stores your funds or assets, we can’t retrieve them if you lose access to your wallet or it’s compromised.
If you forget your password, you can get access to your wallet via your seed phrase, a series of words that accompany all wallet addresses. It’s good practice to write down and safely store your seed phrase in multiple places when you first download your wallet, so if you can't find it, search online for info or reach out to your wallet provider before buying NFTs or storing digital currencies.
Now that you know what a crypto wallet is, check out which ones you can use with NvirWorld.

What are the Service Fees?

If you are a regular Seller, NvirWorld service fees are at 2%. Meaning NvirWorld takes 2% of the transaction sale price.

However, Nvir's Pick Service fees stand at 10%.

Who pays the gas fees?

Usually, gas fees occur when you cancel or lower the price of your listing on the Ethereum Blockchain BUT on NvirWorld there is no gas fees when you cancel or lower the price of your listing!

Furthermore, gas fees are incurred only when the final transaction is confirmed.
Here is how it works:
If the selling price is under 1ETH the Seller needs to pay the gas fees.
If the selling price is higher than 1ETH, NvirWorld will pay the gas fees.
The buyer will not pay any gas fees in any case.

NvirWorld uses the Layer 2 <Stay Pending> solution which lowers drastically all gas fees.
Click here to learn more about “Layer 2 <Stay Pending> solution”

What is Layer 2 <Stay Pending> solution?

NvirWorld NFT Marketplace is using a Layer 2 <Stay Pending - Hybrid Decentralization System> solution but you may wonder what this is all about so we prepare for you a quick introduction.

You first need to know that Ethereum was the first blockchain ever built that allowed for NFTs. Victim of its own success, it has challenges processing efficiently the number of transactions that it sees every day. Eventually, this causes the fees to go up and speed to go down.

That is when Layer 2 solution makes its entrance.

Layer 2 is a solution mainly being built on the Ethereum blockchain, it helps to lower the transaction costs you are charged, meaning lower gas fees, as well as to reduces traffic on the main network which ultimately reduce the speeds of how long the transaction takes.

But we didn’t stop there!

NvirWorld is now introducing Layer 2 <Stay Pending - Hybrid Decentralization System>.

“Hybrid decentralization system” is a technology that brings only the advantages of centralized and decentralized services.
The "Hybrid Decentralization System" takes a step further from Layer 2 to improve gas fees and processing speed even more. The drastic decrease in gas fees has been made possible through a technology called "Stay Pending”. In some cases, gas costs may not be incurred at all.

Don’t waste another minute and start creating NFTs on NvirWorld to enjoy lower than ever gas costs.
