OKBOKB

OKB is the native token of OKX, a crypto exchange that launched as OKEx in 2017 and was renamed OKX in 2022. OKB was first issued in 2018. For years it worked mainly as an exchange token, offering benefits on the platform such as trading fee discounts. Since 2025, OKB has also been the gas token of X Layer, OKX's own blockchain.

X Layer is a layer-2 network on Ethereum built by OKX. After an upgrade announced in August 2025, OKB became the only native and gas token of X Layer, so transaction fees on the network are paid in OKB.

For several years, OKX carried out regular buybacks and burns of OKB, which reduced the supply. In August 2025, OKX carried out a final one-time burn and changed the token's smart contract, which fixed the total supply at 21 million OKB. Current circulating and total supply figures are shown at the top of this page.

OKB rose sharply after the August 2025 announcement. You can see the all-time high and the full price history on the chart above.
