OKB (OKB) Price, Market Cap & Coin Guide

OKB is the core utility token of the OKX ecosystem, a major global cryptocurrency exchange and Web3 platform. Originally launched in 2018 as an ERC‑20 token on Ethereum, OKB has evolved from a pure exchange token into a multi‑purpose asset that powers trading benefits, launchpad participation and an Ethereum Layer‑2 network called X Layer.

In 2025, OKX executed a large one‑time burn and upgraded the OKB smart contract to permanently fix the total supply at 21 million tokens, removing future minting and burning functions. This transition repositioned OKB as a scarce, Bitcoin‑style supply asset with a hard cap.

By category, OKB is an exchange utility token and L2 gas token. It provides fee discounts and VIP privileges on OKX, access to token sales via OKX Jumpstart, staking and earn products, and serves as the native gas token for transactions on X Layer.

OKB is issued by the OK Blockchain Foundation and closely tied to OKX’s product roadmap. Its value proposition combines exchange‑driven utility with on‑chain usage as X Layer’s sole gas asset.

The OKB price chart shows how OKB has traded across different timeframes, from short‑term moves to multi‑year cycles. Short intervals like 24H and 7D highlight near‑term volatility and reactions to OKX product updates, tokenomics changes or broader market sentiment, while 1Y and ALL views reflect OKB’s history from launch through multiple bull and bear phases.

As a token tied to a major exchange and an L2 network, OKB’s price may respond to changes in trading volumes, X Layer activity, new listings, partnerships and general risk appetite in crypto. The chart should be treated as a historical record, not a forecast.

For context on what influences OKB over time, users can refer to the sections on how OKB works and how its fixed‑supply tokenomics and utility model are structured.

OKB is the global utility token of the OKX exchange and Web3 ecosystem. It was created to reward active users, deepen engagement with OKX products and provide a unified asset for discounts, access and on‑chain activity.

Originally, OKB functioned primarily as an exchange token:

• Paying trading fees with OKB unlocked discounts.

• Holding OKB influenced VIP tiers and fee schedules.

• Staking OKB enabled participation in OKX Jumpstart token sales and earn products.

Over time, OKX expanded OKB’s role beyond the exchange. OKB became the native gas token for X Layer, an Ethereum Layer‑2 network built with Polygon technology. On X Layer, every transaction requires OKB to pay gas, linking on‑chain usage directly to demand for the token.

In August 2025, OKX executed a major one‑time burn and upgraded the OKB contract to lock the total supply at 21 million tokens, removing future minting and burning capabilities. This shifted OKB from a deflationary burn model to a fixed‑scarcity model, with utility driven by exchange benefits and L2 gas demand.

OKB is a token, not a native coin of its own L1, because it is issued on top of Ethereum (ERC‑20) and used as gas on an L2 rather than running on its own standalone base chain.

OKB operates across two main environments: the OKX exchange/Web3 platform and the X Layer blockchain.

On OKX:

• Users can hold OKB in their exchange accounts and use it to pay for trading fees, often at a discounted rate depending on their tier and holdings.

• OKB holders can participate in OKX Jumpstart, staking OKB to receive allocations of new token launches.

• OKB can be used in OKX Earn products for staking, savings and other yield‑bearing strategies offered by the platform.

• OKB may be required for certain premium features, voting activities and promotional campaigns within the OKX ecosystem.

On X Layer:

• X Layer is an EVM‑compatible Layer‑2 network where OKB serves as the exclusive gas token.

• Every transaction, smart contract call and transfer on X Layer requires OKB to pay fees, similar to how ETH is used on Ethereum or other L2s.

• Developers can build DeFi, NFT, gaming and other dApps on X Layer, with OKB as the base currency for fees and settlements.

Technically, OKB is an ERC‑20 token on Ethereum. Its smart contract was upgraded in 2025 to remove mint and burn functions, permanently capping supply at 21 million. OKB can be held in any ERC‑20‑compatible wallet and bridged or transferred to X Layer for on‑chain use.

From a user’s perspective, interacting with OKB typically involves:

• Holding OKB on OKX for trading discounts, Jumpstart and earn products.

• Withdrawing OKB to a personal wallet for self‑custody or DeFi use.

• Bridging OKB to X Layer to pay gas and interact with L2 dApps.

OKB’s tokenomics have evolved from an exchange‑driven burn model to a fixed‑scarcity design tied to X Layer utility.

Key elements:

• Initial design: OKB launched with a larger supply and a quarterly buy‑back‑and‑burn mechanism, where a portion of OKX trading fee revenue was used to buy and burn OKB.

• 2025 upgrade: OKX executed a one‑time burn of tens of millions of OKB and upgraded the smart contract to remove mint and burn functions.

• Fixed supply: Total supply is now permanently capped at 21,000,000 OKB, with all tokens in circulation.

• No further burns or minting: under the upgraded contract, OKB can no longer be created or destroyed.

Utility and demand drivers:

• Exchange utility (legacy and partial): historically, OKB provided trading fee discounts, VIP tier benefits, Jumpstart access and earn products. Some of these mechanics have been adjusted over time, with more emphasis shifting to X Layer.

• X Layer gas: OKB is the sole gas token on X Layer, meaning all on‑chain activity requires OKB. This creates a direct link between L2 usage and token demand.

• Scarcity narrative: the 21 million cap positions OKB alongside other fixed‑supply assets, with value driven by utility, adoption and market sentiment rather than ongoing burns.

This structure aims to align OKX’s product ecosystem, X Layer growth and long‑term holder incentives under a simple, fixed‑supply framework.

OKB is primarily listed on OKX and selected other centralized and decentralized exchanges. A typical path to buying OKB looks like this:

1. Create an account on OKX or another exchange that supports OKB.

2. Complete any required identity verification.

3. Deposit fiat currency or another cryptocurrency, such as USDT, USDC or BTC.

4. Search for OKB and choose a trading pair like OKB/USDT, OKB/USD or OKB/BTC.

5. Place a market order to buy instantly or a limit order at a chosen price.

After purchasing OKB, users can keep it on the exchange for trading, Jumpstart and earn products, or withdraw it to a non‑custodial wallet that supports ERC‑20 tokens and, if desired, bridge it to X Layer.

OKB can be stored in any wallet that supports Ethereum and ERC‑20 tokens. These include exchange wallets, browser and mobile wallets, and hardware wallets integrated with Ethereum.

For holding and use:

• Exchange wallets (OKX): convenient for active traders, Jumpstart participation and OKX Earn products.

• Non‑custodial wallets: allow users to control their private keys and interact directly with Ethereum dApps, bridges and X Layer.

• Hardware wallets: provide an extra security layer for larger OKB balances by keeping private keys offline.

Common use cases for OKB include:

• Paying and discounting trading fees on OKX (where applicable).

• Staking for Jumpstart token sales and earn products.

• Holding as a long‑term position tied to OKX and X Layer adoption.

• Using as gas on X Layer for transactions and smart contract interactions.

Good practices:

• Confirm which networks and contract addresses a wallet supports for OKB.

• Safely back up seed phrases and private keys.

• Verify the correct network (Ethereum vs X Layer) and address before sending OKB.

• Use strong passwords and enable additional security features where possible.
