OKB

OKB is the utility token of OKX, one of the world's largest cryptocurrency exchanges. It was issued by the OK Blockchain Foundation and launched in 2018 as an ERC-20 token on Ethereum, initially without an ICO or public fundraising round. Holders use OKB primarily to reduce trading fees on the exchange and to access services across the broader OKX ecosystem, including token launch platforms and the exchange's Layer 2 network activity.

Origin and supply changes

OKB began with a planned supply of one billion tokens, of which 60% was earmarked for OKX customers through community-building and marketing programs, with the remainder subject to multi-year lockups. Over the years OKX ran recurring buy-and-burn programs that steadily removed tokens from circulation. Following a major supply overhaul, the maximum supply now stands at 21 million OKB, all of which is in circulation — an unusually clean supply structure for an exchange token, echoing Bitcoin's 21 million cap.

Role in the ecosystem

As a centralized exchange token, OKB does not secure its own base-layer blockchain the way a Layer 1 coin does. Its value proposition is tied to utility within the OKX platform: fee discounts, participation in token sales, and integration with OKX's on-chain products, including its Ethereum Layer 2 infrastructure. The token exists on Ethereum and related networks rather than on a standalone chain with its own consensus mechanism.

OKB's trajectory illustrates a common pattern among exchange tokens: launch as an ERC-20 asset, distribution weighted toward platform users, and progressive supply reduction through burns. Its fortunes are closely linked to the health and activity of the OKX exchange itself, which is an important consideration when evaluating the token's role compared with decentralized network assets.
