How to Transfer, Mint and Sell NFTs Gas Free on Opensea

Jump to a section

Ctypocurrency collecting has grown in popularity dramatically this year. As a result, many secondary markets have appeared for trading these unique commodities.

As a refresher for those who have never heard of non-fungible (or NFT) tokens, NFTs are tokens that are distinct from each other due to particular attributes or identifications.

When it comes to tokenizing assets and contracts, we've found that NFTs play a big part in the concept of composability—or diverse products interfacing with one other to form an ecosystem.

An industry-leading decentralised exchange for NFTs called OpenSea, developed on Ethereum, is the subject of this overview.

What is OpenSea?

OpenSea is the first and largest peer-to-peer marketplace for NFTs, where anyone can buy and sell virtual goods using smart contracts.

Products here must be 100% digital and tokenized, so proof of ownership and transfer of ownership can be recorded on the blockchain.

To date, Animoca Brands, Stanford StartX, and David Pazdan of MetaMask have contributed a total of $2.1 million to OpenSea, bringing the total amount raised to little over $4 million dollars. YCombinator, Founders Fund, Coinbase Ventures, 1Confirmation, Blockstack, and Blockchain Capital were among the backers of previous rounds of fundraising.

Collectibles, games, and other digital goods are among the items availble on OpenSea. All transactions are protected by smart contracts. Because the assets are produced and stored on the Ethereum blockchain, they can be accessed at any time.

Alex Atallah and Devin Finzer started this business in January of this year. With backgrounds from Stanford, UC Berkeley, Palantir, Google and Facebook and Pinterest respectively, each bring a wealth of knowledge to a team of experts. This project's key partners are BlockStack, Quantstamp, Trust Wallet, Coinbase, Founders Fund, Blockchain Capital, and 1C.

Before you can use this service, you must first download and install MetaMask on your computer. An email address and personal information are required to open an account. To make purchases, you'll need Ethereum, which you may get from an exchange.

You have the option to read through the content or do a specialised search on the website. Other options include entering into a bidding war with other people, or even setting up your own auction. Auctions, on the other hand, typically sell rare or unsold objects at a faster rate than ordinary sales.

Prices might vary substantially based on the item's origin, whether it is discounted, and other factors. Once you've earned ownership rights to digital assets, you'll be able to sell them again using the same account. There are unique rules for developers, so be sure to read the next section to learn more.

How can I buy an NFT on OpenSea?

OpenSea offers NTFs in a wide range of categories from art and music to domain names and virtual worlds. There are a seemingly interminable number of listings in each category, making it difficult to sort through them all. Things may be narrowed down fortunately.

Select All Items, Individual Items, or Bundles from the Filter drop-down menu that appears. Other options include sorting by price, the date an item was advertised, and more. Alternatively, you can put a word or phrase into the search field at the top of the page.

Occasionally, an account or collection will have a blue checkmark next to it. In the same manner that you see verified accounts of public figures on Facebook or Instagram, OpenSea has confirmed this account. Having a blue checkmark indicates that it's safe.

In the status area of a collection, you will find the Floor Price. Power users can check the lowest price of any NFT in a certain collection by using this function. The pricing of this item is always being updated.

If you wish to use OpenSea to conduct transactions, you'll need Ethereum. Don't worry if you don't have any yet! Purchasing Ethereum with your wallet is a simple process. OpenSea's wallet icon can be found by clicking on it on the website. Click the Add Funds button.

You can now choose to buy from an exchange or use a credit card. Just copy the wallet address you are given and send ETH to it after purchasing ETH on Coinbase, Voyager, or any other exchange that you choose to use if you wish. You may also be able to use a credit card to purchase Ethereum, depending on your location. Keep an eye on your credit card company's costs.

What is a crypto wallet? It's something that allows you to store, send and receive digital currencies like bitcoin. You'll need a crypto wallet in order to make peer-to-peer transactions. You can use a wallet for one cryptocurrency, a wallet for multiple cryptocurrencies, or a wallet that is custodial (like the ones seen on cryptocurrency exchanges).


To sum it up, there are a wide variety of wallets from which to choose. This section explains the workings of digital wallets and explains the many types of wallets available. We also give some suggestions on which wallets to use in different situations.

What Is the Best Wallet for you? 

In most cases, a multi-coin wallet like Ledger, Binance, or Coinbase is the most practical option. MetaMask or TrustWallet are two options for DeFi web3 wallets. See our "How to Trade Cryptocurrency – For Beginners" page, where we walk you through using Coinbase if you want a basic wallet-exchange solution.


An electronic wallet is a piece of software that allows users to store and access their bitcoin assets.


There are a lot of different wallets out there, but in general, every given wallet will be able to hold one or more "public addresses" for one or more cryptocurrency.


Addresses that can be shared publicly are known as "public addresses," and they can be used to receive a certain sort of cryptocurrency (for example, Bitcoin addresses are required to receive Bitcoin).


A coin's blockchain is linked to every address associated with that address.


If you are the owner of an address, you can use a wallet to see the balances connected with that address and to move money around the blockchain.


To prove ownership of an address in non-custodial wallets, the private key (the secret code associated with a public address) is used. Your password is all you need to get into your custodial wallet, which is held by a third-party custodian (such as a broker, exchange, or other third-party custodian).


You can think of your wallet as an online bank account, with your address being the same as your account number, the blockchain being like the bank's ledger, and your wallet' s custodian acting in the role of your banker.

What is the Best Wallet for NFTs on OpenSea?


After smart contracts, the wallet you use to buy and sell NFTs on OpenSea is the second most critical factor in securing your NFTs. To use an ERC721 and ERC1155-based dapp like OpenSea, you'll need a secure, functional, and adaptable cryptocurrency wallet.


It's possible to lose all of your NFTs and other crypto assets if you use a less secure wallet or disclose your seed phrase / private key with someone else.


MetaMask, Bitski, Fortmatic, and mobile wallets like Trust Wallet can all be used to access and use OpenSea.


As far as wallets go, MetaMask is the best for OpenSea and most other decentralised applications.


However, MetaMask isn't the most secure cryptocurrency wallet out there. This wallet is vulnerable to a wide range of dangers because it is connected to the internet and hence vulnerable to cyberattacks.


For OpenSea, a hardware wallet like Ledger is preferable over a MetaMask-based wallet. You can utilise dapps like OpenSea more securely if you connect your hardware wallet, or cold wallet, to MetaMask.


Even if MetaMask or your PC is infected, your NFTs and other crypto assets remain safe in a hardware wallet.


How can I mint my NFT on OpenSea Gas Free?


Transaction fees for NFTs include gas costs, as everyone who has done so knows. The fee is used to compensate the blockchain network's miners. The cost of gas can sometimes exceed one hundred percent of the token's value. There are better ways to buy and sell NFTs without needing to spend more than you get in return.


Polygon chain can be used as an alternative to the Ethereum chain. Layer 2 blockchain Polygon enables users to acquire or mint NFTs with no gas fees at all.


Transactions in ETH will still occur, but the currency will be stored on a different blockchain. Polygon, on the other hand, has no transaction fees whatsoever.


OpenSea is a good place to start when it comes to trading on Polygon. It offers a high level of usefulness and efficiency, which makes it easier to carry out business as usual. Buyers and artists alike will be able to purchase more work without having to worry about additional payments.


Depositing money into the Polygon chain is the first step. 'Bridging' is the term for this technique. In order to transfer ETH between Ethereum and Polygon, there needs to be a bridge. Bridges can be made easier with the help of OpenSea.


OpenSea can be accessed by clicking on the wallet symbol on the main screen. Your Ethereum balance will be displayed in the window. A three-dot menu item called "Bridge to Polygon" is available.


Specify the amount of ETH you wish to transfer to the polygon in the popup that appears. This transaction will incur a cost because of the fact that Polygon and Ethereum need to communicate with each other. 


Bridge a large amount of ETH at once so that you don't have to pay gas over and again. We made the transfer from Ethereum to Polygon to prevent this, and we don't want to waste our money on another gas. To bridge, you pay a fee equal to one ETH or one-fifth of that amount.


Bridging will begin when you enter the amount and click "Convert Tokens." It'll only take a few minutes, maybe even less. The purple ETH will appear in your wallet after the process is complete. Your ETH is tucked away inside the Polygon network there.


How can I transfer my NFT on OpenSea?


An essential skill for everyone interested in working with blockchains is the ability to generate NFTs. Why? Decentralized NFT-creation methods will become increasingly sought-after as time goes on, and the need for those who know how is expected to rise in the coming years.


Because of this, we hope you put the information you've gained here to good use. After reading this, you now know that with the help of moralis you can write a simple dApp to generate randomly generated NFTs. On the other hand, you've learnt how easy it is to display or list the NFTs you've created on your OpenSea account. NFTs can be automatically uploaded to OpenSea if you are using the same wallet as before. However, you must confirm that you are connected to the same internet service provider (the mainnet or testnet).

Following the announcement of $100 million in Series B fundraising and a $1.5 billion valuation, OpenSea has now become one of the crypto unicorns. Andreessen Horowitz, a venture capital firm based in the United States also known as a16z, served as the group's leader.


Polygon has been added to OpenSea's Blockchain support as of July 20, according to a blog post. Since it has received $100 million in funding from OpenSea, it is now possible for developers to earn their way into bitcoin.


Unicorns are companies with a market valuation of greater than $1 billion. Additionally, Coinbase, Animoca Brands, and Chainalysis are just a few other notable cryptocurrency unicorns that have recently joined the ranks of Open Sea's growing roster of peers.


Hedge fund and private equity firm Coatue, as well as actor Ashton Kutcher and NBA star Kevin Durant, all contributed to the fundraising effort. However, the company has stated that the service is completely gas-free, allowing consumers to earn their way.


Furthermore, OpenSea plans to increase its support for Dapper Lab's Flow blockchain and Tezos in the near future.
