ONEchain (ONE), formerly known as CROSS, is a gaming-optimized Layer 1 blockchain designed to provide players with true ownership of in-game assets through a decentralized, EVM-compatible infrastructure. The network offers a modular development framework including SDKs, APIs, and smart contract templates to simplify blockchain integration for game studios. Its Game Token Protocol enables games to issue their own tokens and NFTs, so players can hold, transfer, and trade supported in-game assets such as currencies, items, and characters outside individual games. ONE is the native token used for network fees and staking. The project follows a "Play First, Grow Together" model focused on connecting players and developers through tokenized game economies.
