What makes this exchange so successful through this article!

2. Opensea’s USP

2.1. Advantages

  • Transactions will be expressed in the form of a smart contract (Smart Contract), no need to go through any third intermediary.
  • Limit the risk of the exchange because the assets will be stored directly on the user’s wallet.
  • Users can take full ownership of NFTs purchased on OpenSea.
  • Get creative & NFTs are also recognized by floor auctions.
  • Free transactions, no strings attached and reasonable fees.

2.2. Disadvantages

  • The platform charges a 2.5% fee in addition to the sometimes extremely high ETH gas fee. Meanwhile, some markets do not charge fees.
  • Apart from the Ethereum blockchain, OpenSea does not support other popular blockchains such as Solana, Cardano, and Tezos. With its fast speeds and negligible fees, Solana has grown in popularity over the past year, making it the preferred blockchain for many crypto traders.
  • OpenSea only allows royalties up to 10% for artists, which means secondary sellers can keep more of their profits.

3. How to Use Opensea

The first condition for trading on OpenSea exchange is that we need a “wallet” (e.g. Metamask, Coinbase Wallet, …) to be able to connect to pay fees as well as receive other purchases.

3.1. How to Connect your wallet with OpenSea

Option 2: Or you can directly access the wallet icon on the right corner of the interface screen.

Note: To use OpenSea exchange, you need to deposit some ETH into your wallet before trading.

Like many DeFi platforms, OpenSea works with most Ethereum wallets, so choosing a wallet to use MetaMask as an option according to GameAZ will be the most optimal..

When you choose NFT, it will work by auction or instant buy. The buyer makes an offer and the seller decides whether to accept the offer. The sale is then completed.

Alternatively, the buyer can pay the full asking price and get the NFT by selecting the “Buy now” option.

When using the “Buy now” function, transactions are paid with ETH or any compatible token requested by the buyer. To bid and make offers, buyers need to use WETH-covered Ether.

You can completely set a deadline for an NFT sale. Selectable timelines include: 1 day, 3 days or 1 week. It is also possible to customize the time through the calendar.

You can then set up the NFT for a specific buyer. The way to do this is to paste their wallet address into the “Reserve for a specific buyer” box. You’ll see fees from the sale listed at the bottom:

  • OpenSea’s “service fee” is 2.5%.
  • The creator royalty “Creator Royalty” is 10%,

5. The future of the NFT trend in 2022

Based on the experiences that GameAZ has gathered, here are the trends we are looking forward to in 2022:

5.1. Increased NFT Utility

Gadgets are starting to take shape across the industry, especially in terms of enriching different experiences, be it fan engagement for collectors or exclusive access to events, by owning these digital assets.

For example, in September 2021, we saw Dallas Cowboys quarterback Dak Prescott release an NFT collectible in which buyers can unlock items like autographed cards or jerseys. By combining the physical and digital worlds in this way, NFT is becoming increasingly relevant to an audience that is not beyond the hardcore early adopters. Essentially, by treating art as more than just digital itself, we are all starting to learn about possible use cases for this technology.

5.2. Tight controls around cryptocurrencies

With the interest of crypto projects having continued to grow over the past year, I imagine we will see an increase in the scrutiny of the various coins coming to market. With the growing number of projects seeking to benefit from relatively standard anonymity existing in the space, I would expect investors to take a more disciplined approach when assessing the value of any potential investment.

Most notably, an unknown group of people were able to defraud investors of millions of dollars thanks to the popular K-dramas, Squid Game. Thus, 2021 has seen a regulatory “Sword of Damocles” bar hover over crypto markets, leaving the regulatory framework open as we continue into 2022. What I would like to see is an Stronger leadership from financial regulators, as the current approach has been at best not harmonized.

5.3. Merge Metaverse

In addition to the fact that we are all learning about the benefits of an even more connected world, I believe we will begin to see certain metaverse projects set apart from the rest of the pack. In what could be a saturated market, we will see investors, creators, and users in general begin to gravitate toward the most traction converters. There are only so many cases where investors in digital land will turn a blind eye to investments that never materialize due to insufficient development of the broader ecosystem. Similarly, groupthink is not just a disease that exists in Web 2.0. People want to be where everyone else is. So, I imagine, the metaverses capable of building the biggest communities will be the survivors of the inevitable merger.

5. The future of Opensea exchange?

In January 2022, OpenSea closed a $300 million Series C funding round led by Paradigm and Coatue, bringing the platform’s valuation to $13.3 billion. While the company says it’s not actively planning an IPO, hiring a seasoned CFO in 2021 points to it. Previously, Brian Roberts served as CFO of car-sharing platform Lyft, where he led the company’s IPO, raising $7 billion in capital.

As the leading NFT market, OpenSea will always face competition but OpenSea’s large market share could help it continue to lead in the long run. OpenSea once saw a 646x increase in transaction volume in 2021, surpassing US$14 billion. When the entire NFT market is measured to be US$25 billion in 2021, that means OpenSea accounts for 56% of the total trading volume.

Investment bank Jefferies expects the NFT market to surpass $35 billion by 2022 and $80 billion by 2025. Given the advantage of scale, OpenSea is likely to remain the leading NFT market for the foreseeable future.
