Key Points (tl;dr)
  • is an NFT marketplace aggregator that not only provides NFT traders with fully visibility of the entire market supply but also allows users to bulk buy and sell NFTs.
  • Gem’s unique features include a sweep button, integrated rarity filters, the ability to pay with any ERC-20 token as well the retention of rewards from integrated marketplaces such as LooksRare.
  • We believe OpenSea’s acquisition of Gem is a combination of an “acqui-hire” as well as a defensive move. Buying acquiring Gem OpenSea stands a much better chance of retaining high-volume “pro” traders. However, it also benefits from the technical prowess of the Gem development team and can use the aggregator a “test lab” for future feautres on OpenSea.
  • The acquisition comes soon after a core developer team member, Josh Thompson, was removed for the team and cap table due to allegations of rape and sexual harassment.

What is Gem NFT?

Gem NFT is the leading NFT marketplace aggregator, covering all of the most popular Ethereum-based NFT marketplaces, including OpenSea, LooksRare, X2Y2, Rarible, and NFT20. NFT aggregation platforms allow users to scan the market and buy NFTs in bulk rather than purchasing each NFT individually.

NFT marketplace aggregators are particularly popular amongst big traders who like to purchase multiple items in bulk.

Gem NFT allows you to bundle together listings from various different marketplaces and buy them in one go.

Aggregation platforms also have the added benefit of providing a holistic view of the market, effectively solving many of the liquidity issues involved with switching to a competing marketplace.

Gem NFT has only been around for about 3 months after launching in January 2022.

The idea isn’t new, since their primary competitor has been on the market for at least twice as long.

However, despite having the first-mover advantage, Gem quickly took the lead by iterating much faster and excelling on the user experience front.

What Are Gem NFT’s Features?

Gem’s list of features includes an aggregated search function, a discover page, batch buy and sell, up to 40% gas savings, multi-token payment options, and a rarity filter. It covers markets places such as OpenSea, LooksRare, Rarible, X2Y2, and NFT20.

The most obvious benefit of Gem is the fact that you have one unified interface from which you can scan the entire market.

Instead, you just look at what’s available straight from your Gem NFT dashboard. allows you to batch buy and sell NFTs, not only saving your time and effort but all up to 40% on gas fees thanks to optimized smart contracts.

And it doesn’t stop there.

They even have an integrated rarity filter and they allow you to pay with any ERC-20 token.

And they’ve even managed to integrate marketplace rewards from sites like LooksRare, that otherwise would have ended up in the aggregator’s wallet.

Here’s a quick overview.

Features include:

  • Aggregated search function
  • Discover page
  • Batch buy and sell
  • Save up to 40% on gas
  • Pay with any token
  • Rarity filter

Why Did OpenSea Acquire Gem NFT?

OpenSea’s acquisition of Gem in April 2022 was a strategic move to defend market share and invest in superior technology. OpenSea is now in a position to use Gem as their test lab for professional traders while keeping OpenSea as simple and accessible as possible.

On the 25th of April 2022, OpenSea announced that it had acquired for an undisclosed amount.

The official press statement claimed that the acquisition was part of their efforts to serve more experience “pro” users.

Gem will continue to operate as a separate product and brand, however, this obviously allows OpenSea to address a customer segment that otherwise would have been difficult to serve from the main OpenSea website.

In fact, we wouldn’t be surprised if OpenSea used Gem as a sort of test lab where new features are tested first.

Once certain features are battle-tested, they can be integrated into OpenSea’s marketplace quite easily.

However, we’re not convinced that this is the only reason for the acquisition.

Although OpenSea still dominates the market by a wide margin, the competition is growing stronger by the day.

Any standalone NFT marketplace would traditionally have a hard time gaining traction simply because the largest volume traders are attracted by liquidity.

Since OpenSea offers the greatest liquidity, more often than not they would have to go back to OpenSea to make their trade.

Even though they might hate OpenSea.

Aggregation platforms like Gem significantly reduce this barrier by providing transparency across many marketplaces.

And if you take this one step further, once an NFT aggregator gathers enough users, it is technically in a position to start acting as its own marketplace.

The pending launch of Coinbase NFT will only make it worse for OpenSea.

We believe the acquisition of Gem NFT is a very clever strategic move for the following reasons:

  • OpenSea retains “pro” trading volume (defensive move)
  • Gem becomes OpenSea’s “test lab”
  • The best features are integrated into OpenSea
  • Gem provides OpenSea with better visibility into competing marketplaces
  • OpenSea could launch a community token via Gem, rather than via OpenSea itself

There are many benefits to this acquisition for OpenSea.

Unfortunately, the community will most likely hate most of it.

Gem NFT Team Controversy

About two weeks before the acquisition, Gem announced the removal of Josh Thompson from their team.

Thompson was a core developer and former shareholder at Gem, going under the pseudonym “Neso”.

Unfortunately, information surfaced that led to allegations that Thompson had engaged in rape, sexual harassment, and grooming of minors.

The removal of Thompson from both the team as well as the cap table (he previously held shares) was apparently a key factor in enabling the acquisition by OpenSea.

The formal announcement by OpenSea addressed the issue head-on, stating that it had come up as part of their due diligence process.


The acquisition of Gem NFT by OpenSea took the entire NFT scene by surprise.

While the investment makes total sense for OpenSea which has been struggling with various scandals and increasing competition, the NFT community is a lot less happy.

Most of the community is rooting for the underdogs, the smaller competitors who are challenging the status quo.

Every time an incumbent like OpenSea buys a competitor, it’s another hit to a scene whose morale is built on the ambition to take on the wealthy establishment.
