What is OKB?
Exchange origins
OKB launched publicly in 2018 as an Ethereum token. The OK Blockchain Foundation and OKX developed it for the exchange's ecosystem. Mingxing 'Star' Xu led its introduction. Account uses have included trading-fee discounts and access to eligible Jumpstart activities. These benefits follow the exchange's product and account conditions.
X Layer and markets
OKB is the native gas asset of X Layer. Applications pay it for transfers and smart-contract execution on that network. X Layer includes an EVM environment supporting Ethereum-style contracts. The Exchange OS design also requires venue deployers to stake OKB. Its architecture separates asset anchoring and governance from the trading environment used for order matching.
Revised supply
The August 2025 economic upgrade established a supply of 21 million OKB after a one-time destruction of reserves. That upgrade removed minting and manual burning functions from the token contract. It also phased out OKX support for Ethereum withdrawals in favor of X Layer. OKT balances on the exchange were converted under a separate published conversion schedule. The former periodic exchange-buyback model should therefore be read in the context of this later revision.
