What is OKB? It is the utility token of the OKX exchange and Web3 ecosystem, with uses spanning trading benefits, wallet services, and the X Layer Ethereum Layer 2 network. Unlike a standalone Layer 1 coin, OKB is closely tied to OKX products and infrastructure.
Core technology and blockchain architecture
OKB was originally an exchange-issued token with representations on multiple networks, including Ethereum, OKEx Chain, and Sora. Its role expanded significantly in 2025 when OKX made OKB the native gas token of X Layer, its Ethereum-based Layer 2 network.
X Layer originally used Polygon CDK and zero-knowledge technology. Following an upgrade completed on 5 August 2025, current X Layer documentation describes an enhanced Optimism Stack architecture with an EVM-equivalent execution environment. This allows Ethereum-compatible smart contracts and decentralized applications to operate on X Layer, while OKB pays transaction fees.
The network connects OKX Exchange, OKX Wallet, OKX Pay, Ethereum and other compatible infrastructure. X Layer uses a sequencer to order transactions and relies on Ethereum-linked settlement and Layer 2 security mechanisms rather than an independent Layer 1 validator network.
Primary uses and applications
OKB provides utility across the centralized OKX platform and its on-chain ecosystem. Exchange-related uses include trading-fee discounts of up to 40%, participation in OKX Jumpstart activities, selected Earn products, trading, custody, transfers, and some lending and borrowing services.
Within X Layer, OKB pays gas fees for transactions and smart-contract execution. It also serves as the native asset for decentralized applications focused on decentralized finance, payments and real-world assets. X Layer became the default public network for OKX Pay, while OKX introduced fast, gasless withdrawals for selected assets through the network.
OKB can also be transferred between OKX, X Layer, Ethereum and compatible networks. Its utility therefore depends on both OKX adoption and activity across the applications connected to X Layer.
Who is behind OKB and where is it based?
OKB is operated within the OKX ecosystem. OKX identifies Mingxing “Star” Xu as its founder and CEO. Xu previously founded Okcoin in 2013, while OKX was founded in 2017. OKB was announced in late 2017 and publicly launched in 2018, originally in connection with the OKEx Token Trading Loyalty Program.
X Layer was developed by OKX in collaboration with Polygon Labs. The available sources do not identify a separate, independently governed foundation or anonymous developer group responsible for OKB.
OKX operates through multiple regional entities rather than one universally applicable company. Aux Cayes FinTech Co. Ltd. is identified as a Seychelles-registered company. Other disclosed entities include OKX Europe Ltd, incorporated in Malta, and OKX SG Pte. Ltd., a Singapore-regulated operating company. The applicable entity depends on the customer’s jurisdiction and service, so the entire OKX group cannot be assigned to one country or legal entity.
Tokenomics and supply
CoinStats reports a circulating supply of 21,000,000 OKB and a total supply of 21,000,000 OKB. The figures indicate that the full stated supply is currently circulating.
In August 2025, OKX announced a one-time burn of approximately 65.26 million OKB held in reserves and accumulated through earlier buyback programs. The same restructuring permanently removed minting capability, ended the previous manual-burn model and fixed the maximum supply at 21,000,000 OKB. Earlier buybacks used part of OKX’s trading revenue to purchase and burn tokens, but that recurring model was replaced by the permanent supply cap.
The market snapshot lists OKB at $121.29, with a 24h change of -0.33%. Its market cap is $2.55B (rank #55), 24h volume is $17.36M, and its all-time high is $228.74, the current price is 46.98% below it.
Security, partnerships and development
OKB does not have its own independent consensus mechanism. Its security depends on the host networks, smart contracts, bridges and OKX infrastructure where it is issued or used. X Layer relies on its sequencer, settlement contracts and Ethereum-linked Layer 2 mechanisms, while exchange-held OKB depends on centralized custody and account security.
Key integrations include Polygon Labs and Ethereum infrastructure, alongside OKX Exchange, OKX Wallet and OKX Pay. OKX also has major commercial partnerships with Manchester City and McLaren Racing, which broaden the brand’s Web3 exposure but do not represent protocol-level dependencies.
Current development priorities include expanding X Layer’s DeFi, payments and real-world-asset applications, improving developer tooling and bridges, and pursuing interoperability initiatives involving Polygon AggLayer and LayerZero. The roadmap also emphasizes on-chain financial infrastructure for spot, perpetual and outcome markets. OKB’s main differentiator is therefore its dual role as an OKX ecosystem token and the native gas asset of an exchange-linked Ethereum Layer 2.
