Today, Cronos announced Cronos Play, a comprehensive modular suite of developer tools and services to streamline the creation of gaming and GameFi applications in the Cronos blockchain ecosystem.

Live since November 2021, Cronos is an EVM-compatible chain designed to support the Creator Economy with applications such as DeFi and GameFi, ultimately serving as foundational infrastructure for the Metaverse. Cronos delivers dramatically faster and cheaper transactions than Ethereum mainnet, making decentralized applications (dApps) and smart contracts greener and more user-friendly.

Since its launch in November 2021, Cronos has skyrocketed to being a top 10 blockchain by total value locked (More than $US 4billion), with 25% month-on-month user growth and more than 200 dApps.

Cronos Play is an essential pillar of Cronos’s strategy to bring tens of millions of end-users to Web3. The developer platform will consist of a wide range of integrations, developer products, and services supporting multiple game platforms and languages such as the Unity engine, the Unreal engine, and the C++ programming language.

As a first milestone, Cronos Play is announcing its integration with ChainSafe’s Gaming SDK, web3.unity, an open-source software development kit maintained by ChainSafe, a leading blockchain R&D firm specializing in infrastructure solutions for web3.

ChainSafe’s Gaming SDK, web3.unity, enables mobile, web, and desktop games created with the Unity engine to easily interact with common web3 smart contracts such as ERC20 and CRC20 token contracts, and ERC721 and ERC1155 NFT contracts. Game developers will be able to access on-chain data in-game, fetch user wallet addresses, connect to the Cronos chain, query cryptocurrency and NFT balances, send transactions, and transfer NFTs as part of the suite of out-of-the-box functionalities

To support the adoption of ChainSafe’s Gaming SDK by game creators, Cronos is releasing developer documentation, code samples, a demo application, and an NFT testnet faucet suitable for teams to develop and launch Unity games on the Cronos blockchain. Please visit for more information.

Ken Timsit, managing director of Cronos, said: “The Cronos user base is already 500,000 strong with potential to grow amongst the tens of millions of, and $CRO users. Our community is incredibly engaged, transacting once every two days on average. They tell us every day that they are hungry for more games and metaverse experiences. We are at an inflection point and it is time for game developers to pay close attention to Cronos. The ChainSafe Gaming SDK is an outstanding developer tool that will make it easier to build on Web3.”

“Since the beginning, we have always taken pride in our technologically objective, multi-chain oriented vision,” Aidan Hyman, CEO and co-founder of ChainSafe said. “Making the Gaming SDK available on Cronos is an extension of this vision, and we are incredibly excited to see the wealth of gaming innovation that is to come from the Cronos ecosystem with this integration.”

The announcement of Cronos Play is the first step of a multi-year product and ecosystem development effort that will greatly enhance the quality of GameFi user experiences in Web3.

In the near future, Cronos Play will announce additional integrations and products developed together with, the world’s fastest-growing cryptocurrency exchange, as well as partners and game studios.

The Cronos Play roadmap includes integration with a number of open-source libraries as well as connectivity to commercial services such as OAuth and Pay. With’s help and expertise, games will be able to easily receive credit card or crypto payments. Users will be able to sign blockchain transactions via the DeFi wallet, the MetaMask wallet, or other wallets compatible with Wallet Connect.
