Justin Kahn, co-founder of Twitch, announced today that new blockchain gaming marketplace Fractal has made it easier for Web3 gamers to log into cryptocurrency wallets.

The new product is called Sign In with Fractal and it acts as a digital cryptocurrency wallet for web 3 players. Once you log into it, you can see the digital assets you own such as non-fungible tokens (NFTs) of different game assets.

The announcement comes two months after the company raised an initial $35 round led by Paradigm and Multicoin Capital.

Fractal is a marketplace for video game players to discover, buy and sell NFT games. Over 121 NFT combinations across 85 games have been launched live on Fractal since January.

“We have a lot of games being logged in to use them,” Kahn said. The company launched with one game and is now moving to more subscriptions.

Sign In with Fractal provides gamers with a cryptocurrency wallet that makes it easy to start playing web3 games, both on Fractal and within partner games. In an interview with GamesBeat, Kahn said players are able to store and trade in-game assets, purchase NFTs, and participate in Fractal tournaments using their Fractal login.

“We created a cryptocurrency wallet that solves some of the issues game developers face when creating Web3 games,” Kahn said. “We are trying to enter the mass market, the majority of non-crypto users playing games. The wallet is a big downfall.”

Blockchain gaming attracted 1.22 million unique active wallets (UAWs) in March, accounting for 52% of industry activity.

“We have noticed that the player does not appreciate the benefits of the blockchain until after the player wants to sell, share or lend their assets. In the beginning, the player just wants to play the game.” Kan said. “So we created a product that makes it easy to get users into crypto games.”

How it works

As part of the integration, logging in with Fractal solved the challenges game studios faced with building a game on top of the blockchain, which could certify the uniqueness of digital elements such as NFTs in games.

Sign In with Fractal for game studios provides an API for game studios to determine what assets a player has in their Fractal wallet, and comes with software development kits (SDKs) for Unity, Unreal, iOS, and Web. Some of the games that have integrated logging in with Fractal include multi-mode games (Tiny Colony), first-person shooters (MetaOps,, BR1), sci-fi MMORPGs (Roguestar), and fighting games (Psyker).

“Sign in with Fractal allows users to sign in to Web3 games with accounts they already have: Google, Twitter or Discord. In about 30 seconds, users can create a fractal wallet, register their initial phrase, and are ready to play on any device. No chrome extension No mobile app download. Quite simply. David Wirtz, Fractal CEO, said in a statement. “And because it’s tied to players’ social media login, it’s very difficult to fall into phishing attacks.”

“We have been talking about the potential of blockchain gaming for a long time. We recently saw successful and seamless adoption of Fractal login among the first 15,000 users who signed up and participated in a live session,” said Chris Scott, Managing Director of Addicting Games, in a statement. on “We’re excited to roll out Fractal login across other web3 games.”

At the moment, fractal login works with Solana cryptocurrency. The company does not support Metamask wallets yet, but it does support Phantom, which is similar to its Solana blockchain counterpart, which is popular in gaming. Kahn said that over time, Fractal will likely add more blockchain solutions.

“Signing in with Fractal is an excellent option for casual users who are discovering web 3 applications. From a technical perspective, the Fractal SDK team provided a clean, well-structured API that allows the use of OAuth and shamir secrets in a seamless and secure manner. Amazingly, its integration with existing wallet infrastructure was It was easy and our team took less than an hour.” Bartosz Lipinski, chief software engineer at Solana, said in a statement. “Signing in with Fractal gave me confidence that we would be able to bring the next hundreds of millions of users into our product without friction.”

Kahn said the Fractal team aims to spark a new wave of innovation that allows games to be more fun, have better aligned incentives between player and game studio, and enable growth faster than ever before. Game companies can contact this form.

A cryptocurrency wallet is similar to a digital wallet, but instead of storing your credit, debit cards and cash, it allows cryptocurrency users to store and redeem their digital assets (Bitcoin, NFTs, etc.). When a user buys cryptocurrency (such as Ethereum, Solana, Bitcoin, etc.), they store it in a crypto wallet and use it to complete transactions. When you buy NFTs on markets like Fractal, those also go into your crypto wallet.

If you’re a gamer and want to start playing a crypto game, Fractal said, knowing how to download a plugin and use a wallet can be confusing. There are many benefits to games moving to Web 3: Bigger, more open economies and real player ownership of assets.

But at first, some or all players may not know anything about encryption, how it works or why it is useful. A game that asks them to download a wallet can discourage them from participating. Only after the player wants to sell, bet or lend their assets will the player appreciate the benefits of the blockchain. In the beginning, the player just wants to play the game.

Login with Fractal allows players to log into web3 games with accounts they already have: Google, Twitter or Discord. In 30 seconds, the player can create a fractal wallet, record the initial phrase, and get ready to play on any device. There is no chrome extension. There is no download for a mobile app. Simply.

“If you lose your Google account, or your Twitter account, you can get it back,” Kahn said.

Kan said that Sign In with Fractal is a dishonest wallet, meaning no third party has access to it — yes, including Fractal itself. He said it’s secure because it’s linked to players’ social login. This makes getting caught in phishing attacks more difficult. For example, if a player tries to log into the Fractal Wallet on a site pretending to be the real site, the player will quickly realize that they are not actually logged in and know that something has happened.

Imagine that you are in the middle of a mission and you have just defeated your boss. Now, the game offers you a chance to mint one of 1000 special swords. You can do this with one click, Fractal said, without leaving the game for an app or browser window.

Sign In with Fractal solves a host of challenges for game studios. Building a game on top of the blockchain is tedious and requires a very specific skill set that is not found in the game studio. In fact, many game studios may not want to hire a cryptocurrency team, and instead prefer to focus on building their game. Logging in with the Fractal API solves this problem by reducing the barrier to interaction with the blockchain. It comes loaded with SDKs for Unity, Unreal, iOS, and Web. Developer documentation is now available at This allows almost any developer to integrate, unlocking a series of benefits:

Signing in with Fractal makes calling the API quick and easy for game studios to determine which assets a player has in their Fractal wallet. Does the player still have the sword he is playing with? Fractal is investing a lot of dollars on servers to make sure it keeps up with changes on the blockchain so the game doesn’t have to.

The Sign In with Fractal feature allows players to trade assets within the game, whether it is peer-to-peer or directly from the game. The company expects that most players will want to buy from within the game, which is the most natural place to buy gaming assets. Mint can also be made upon request.

Instead of holding an event every so often, the game can always offer its digital assets for in-game sale. Players can mint items at any time they want. In this way, the game begins to build much-needed cash flow to support their ecosystem.

Logging in with the Fractal private key is divided into two “secret shares”, one stored on Fractal servers, and one stored locally on your devices. Both secret shares are needed to re-create the private key. Acquiring one share is completely useless and Fractal cannot sign any transactions on your behalf.

First, sign in with the same social account you used on your original device. You should see a prompt to approve an existing device or enter an initial phrase. Go to on an existing device and click Agree, or paste the initial phrase into the dialog. This device will now be fully logged in and can be used to approve other devices.

If you lose all your authorized devices, you will lose all local “secret posts” and the only way to recover your account will be the initial issued gateway. But you have to make sure to store your seed phrase in a safe place.

Signing in with Fractal is currently working on a desktop or mobile web browser. For playing Web3 games on your desktop, Fractal recommends Chrome for stability and performance. Currently, all iOS web browsers are forced to clear local storage after seven days of inactivity. If you only use a mobile phone, be sure to back up your initial phrase.

“Our goal is to make things simpler again,” Kahn said. “Developers are excited because they want to include their users in seamless ways and no one has done that yet.”

The company has about 15 people.
