Crypto development platform Sequence has launched Builder, a full-stack dashboard for game developers that it says will dramatically simplify the process of adding blockchain elements like NFTs to video games.
Sequence was created by crypto infrastructure and game development firm Horizon Blockchain Games, which previously launched the NFT trading card game Skyweaver and raised $40 million in funding from prominent video game publishers Ubisoft and Take-Two Interactive late last year.
โBlockchains are scaling, and theyโre only going to continue to scale more,โ Horizon CEO and co-founder Peter Kieltyka told Decrypt in an interview.
โBut what they really need is the middleware infrastructure. And they need the applications, which are the games and the apps. And thatโs what we do. Thatโs why we offer this batteries-included thing,โ Kieltyka explained.
Sequence Builder allows game devs to import existing NFT collections to incorporate into their games, add a crypto wallet connection function, prepay for gas fees for in-game crypto transactions, and launch a white-label NFT marketplace, to name a few of its features. The builder will also add an NFT minting feature in the future, according to the company.
โWe wanted to give an interface to people who didnโt have to know anything about the blockchain,โ Kieltyka said of Sequence Builderโs user experience and design, which offers a minimalistic dark-mode aesthetic and a side navigation menu that clearly lists the productsโ features.
Game developers can choose to set up wallets that require as little as a Twitch login connection or email addressโan option that can significantly reduce the steps required to create a crypto wallet.

โWeb3 development has been plagued by weak and fragmented tech that destroys the UX for players,โ Sam Barberie, Horizonโs Head of Strategy and Partnerships, said in a statement. โThe bar for seamlessness in gaming is incredibly high, and Sequence Builder ensures that thereโs never friction in any part of the playerโs journey, from account creation to secondary trading.โ
The Builder enables devs creating with popular game engines like Unreal Engine and Unity to add blockchain elements to their gamesโwithout making users leave the game application itself.
โI think a lot of Web3 tech kind of falls short there just being browser-only,โ Barberie told Decrypt in an interview on the decision to offer Unreal and Unity integrations.
โWhat weโre hearing a ton is everybody wants their own marketplace, because everybodyโs pissed off about the royalty thing,โ Kieltyka said, referring to a wave of marketplaces (including Blur and OpenSea) ditching mandatory creator royalty fee payments on NFT sales. Thatโs made it harder for NFT creators to generate ongoing revenue.
โThey donโt want a third-party experience,โ Kieltyka said of blockchain game devs. โThey want to know when people are in their game or on their site.โ
โWe know from our game, and this is obviously true for players in generalโthey donโt want to leave your game,โ Barberie said of Skyweaver, echoing the sentiment that developers donโt want to make users โtab-outโ or leave the game just to buy NFTs.
And while there are other competing blockchain gaming solutions out there for developersโlike Stardust or Thirdweb, for exampleโSequence sees its newest offering as a truly full-stack solution that stands out from the bunch.
โWe have, I would say, a significantly much wider technology stack,โ Kieltyka said, adding that Sequenceโs wallet is a smart contract wallet (as opposed to a simpler EOA-type wallet).
โWe [also] offer an indexer. We have all this core infrastructure that weโve built internally that weโve been running for years,โ the CEO continued, referring to a tool that organizes and presents various blockchain data.
When it comes to adding blockchain networks via the builder, thereโs straightforward toggle buttons to enable different blockchains. The builder will help devs connect their games to over 11 different EVM blockchains if they choose, including Ethereumโs mainnet, Optimism, Polygon, Polygon zkEVM, Base, Oasys, Arbitrum One and Nova, and Avalanche, to name a few.
Asked if Sequence might expand its offering beyond Ethereum networks to something like Solana in the future, Kieltyka said it could happenโif developers really want it.
โI like Solana, I really do. But thatโs not a trivial thing,โ the CEO answered, adding that for now, the team feels confident about its decision to focus on EVM. โWe might support it in the future. If thereโs enough demand for Solana, we will do it.โ
