About ONEchain

$ONE is the native token of ONEchain, an EVM-compatible Layer 1 network built for on-chain gaming. The token pays network gas fees, is staked to run validators or delegate to them, carries governance rights, and is used by developers to deploy games and applications on the network. ONEchain runs Proof of Staked Authority (PoSA) consensus with BLS signatures. Its Mainnet 2.0 upgrade, released in June 2026, introduced a validator and delegation model, burning of network base fees, and a halving-based schedule for network rewards. The chain uses EVM chain ID 612055 and supports standard Ethereum tooling and smart contracts. $ONE has a fixed total supply of 1 billion tokens with no additional issuance. Staking is available to holders through delegation, with a minimum stake of 10 ONE and a 14-day unbonding period. The surrounding ecosystem includes ONEpocket for wallet functions, ONEbridge for cross-chain transfers, ONEnft for NFT trading, ONEramp as a developer SDK, and ONEexplorer as the network block explorer. ONE Store, a South Korean app marketplace acquired by Nexus Co., Ltd. in June 2026, operates as a network validator. The project was previously known as CROSS and rebranded to ONE in July 2026. The rebrand covered naming only. The network, token and team are unchanged. $ONE is issued by OGF (BVI) Ltd., part of the Opengame Foundation, with development led by Nexus Co., Ltd.

Crypto Asset General Risks

  • Investing in crypto assets is risky and each token can have its own set of risks. Below is a list of risks that generally apply to all crypto assets:
  • Volatility: The performance of crypto assets can be highly volatile, with their value dropping as quickly as it can rise. You should be prepared to lose all the money you invest in crypto assets.
  • Lack of protections: Crypto asset investments are unregulated and neither the Financial Services Compensation Scheme (FSCS) nor the Financial Ombudsman Service (FOS) will assist or protect you in the event something goes wrong with your crypto asset investments.
  • Liquidity: Some crypto asset markets may suffer for low liquidity which could prevent you buying or selling your crypto assets at the price you want or expect.
  • Complexity: Specific crypto assets may carry with them specific complex risks that are hard to understand. Do your own research and if something sounds too good to be true, it probably is.

Don’t put all your eggs in one basket: Putting all your money into a single type of investment is risky. Spreading your money across different investments makes you less dependent on any one to do well.
