What happened to the original X1 testnet and the old OKT token ecosystem?

The original X1 project successfully transitioned into the live X Layer mainnet ecosystem. To eliminate network fragmentation, OKX migrated X Layer to the open-source OP Stack architecture, officially joining the Optimism Superchain. As part of this infrastructure upgrade, the old OKTChain and OKT utility tokens were systematically phased out, and native gas operations were consolidated onto the primary OKB token architecture.

Is my OKX Web3 Wallet connected to my centralized OKX exchange account?

No. While both modules are conveniently accessible within the same user interface application, they operate on completely separate infrastructure layers. The OKX Exchange account is a custodial system managed by the corporation, while the OKX Web3 Wallet is a fully independent, non-custodial environment where you alone hold the cryptographic keys or MPC shards to your on-chain assets.

What is the practical security benefit of the new XKO-prefix address format on X Layer?

Because most Layer 2 networks reuse standard Ethereum-style addresses starting with "0x," users frequently copy the wrong address from their transaction history logs and suffer clipboard hijacking exploits. The specialized XKO-prefix provides immediate visual confirmation that the target address is native to X Layer, lowering manual entry risk while maintaining full technical compatibility under the hood.

How does the OKX DEX aggregator offer better pricing than swapping on an individual exchange?

If you execute a large token swap on a single decentralized platform, the immediate supply shortage inside that isolated pool can cause aggressive price slippage. The OKX DEX relies on automated X Routing protocols to scan hundreds of platforms and bridges simultaneously, splitting your order into multiple sub-paths to tap the deepest global liquidity slots and secure the best net pricing matrix.

OKX Tutorial: Wallet, DEX, and Earn Products Explained

May 25, 2026 — By Boni in Tutorials

Unifying centralized exchange liquidity with decentralized web3 autonomy minimizes market friction. We break down OKX advanced trading, keyless MPC wallets, and X Layer mechanics.

What is OKX

OKX is one of the largest centralized cryptocurrency spot and derivatives marketplaces and an expansive Web3 technology infrastructure provider. Founded in 2017 and operating globally under strict tier-1 virtual asset regulatory frameworks, the ecosystem clears billions of dollars in daily transactions.

Rather than functioning as a standard token marketplace, OKX delivers a comprehensive portal that unifies high-frequency centralized matching engines with a native Layer 2 scaling blockchain, a self-sovereign multi-chain Web3 wallet app, decentralized exchange routing engines, and automated passive asset optimization vaults for tens of millions of global users.

To maintain seamless compliance across heavily fragmented global jurisdictions, the parent group operates via geographically ring-fenced corporate subsidiaries. These regional OKXs (spanning specific licensed operational hubs in Europe, Dubai, Australia, and the Bahamas) each enforce custom token listing parameters, localized banking access paths, and tailored consumer safety standards to align strictly with their respective local virtual asset regulatory frameworks.

The Unified Interface: Merging CeFi Liquidity with Web3 Autonomy

Navigating contemporary digital asset markets often forces users to choose between two conflicting operational environments. Centralized exchanges (CeFi) offer deep liquidity books, low trading execution fees, and high-leverage derivatives, but require sacrificing asset custody to a centralized intermediary.

Conversely, decentralized web3 architectures provide absolute asset sovereignty and permissionless access to applications, but expose retail participants to high network gas fees, complex manual cross-chain bridging routes, and fragmented pool depths.

OKX bridges this historic structural divide. By running a centralized trading house alongside a non-custodial web3 portal within a single interface, the platform serves as a versatile ecosystem for modern financial market participants. This comprehensive tutorial details how to navigate the centralized spot and derivatives books, leverage the non-custodial wallet framework, execute cross-chain swaps via its decentralized exchange (DEX) aggregator, and deploy idle assets into interest-bearing Earn vaults.

1. Centralized Core: Spot and Derivatives Execution Architecture

The centralized side of the ecosystem routes all customer transactions through an advanced Unified Account framework. This cross-collateral ledger allows shared margin management, meaning your open spot holdings, stablecoin reserves, and options contracts can simultaneously back complex derivatives positions to optimize capital efficiency.

The Spot and Futures Engines

Spot Trading Workspace: Connects buyers directly to a highly liquid Central Limit Order Book (CLOB). Users can execute immediate market fills or set passive limit, stop, and trailing orders to secure targeted price entries with minimal execution slippage.
Derivatives Workspace: Built for high-performance risk configuration, supporting perpetual swaps, dated futures, and options contracts with leverage scaling up to 100x. Position risk can be structured under isolated or cross-margin mechanics to isolate collateral fields from aggressive market liquidations.

The financial backbone of the exchange relies on its native utility token, OKB. Beyond serving as a global loyalty asset that unlocks up to 40% transaction fee discounts for holders on the centralized exchange, OKB serves as the foundational economic engine for the platform's external on-chain networks.

2. The Web3 Powerhouse: The Non-Custodial Wallet

With a single toggle at the top of the interface, the app transforms from a centralized custodial environment into the fully independent OKX Web3 Wallet.

Operating as a completely self-sovereign application, the Web3 Wallet gives you full ownership over your cryptographic private keys. The system incorporates two advanced account custody options:

Traditional Seed Backups: Generates standard 12-to-24-word cryptographic master recovery phrases that users record offline using physical steel slates or paper media.
Next-Gen MPC Infrastructure: Utilizes Multi-Party Computation (MPC) principles to deliver a completely keyless onboarding experience. The private key is programmatically split into three separate encrypted data shards distributed across your personal device, cloud storage systems, and the platform's secure network nodes. This format eliminates the single point of failure inherent to written recovery sheets while maintaining true non-custodial control.

3. Direct Liquidity Hub

Embedded natively inside the Web3 portal is the OKX DEX, a highly sophisticated decentralized exchange and cross-chain bridge aggregation gateway.

When swapping tokens on-chain, relying on a single localized automated market maker (AMM) can lead to severe pricing slippage due to shallow capital pools. The platform solves this through X Routing technology. The aggregation algorithm continuously scans more than 400 independent decentralized exchanges and cross-chain liquidity bridges concurrently.

When you configure an on-chain swap, X Routing automatically divides your transaction payload across the most capital-efficient paths on the market. It optimizes gas fees, eliminates artificial slippage markups, and enables seamless cross-chain asset swaps between entirely different Layer 1 and Layer 2 ecosystems in a single, atomic user operation.

4. The On-Chain Infrastructure: X Layer Scaling Engine

If you have been tracking the platform's underlying technical development, you might recall early iterations of its native Layer 2 scaling blockchain under the name "X1." The network has completely matured into a public, zero-knowledge mainnet ecosystem renamed X Layer.

In a major technical migration finalized in late 2025, OKX transitioned X Layer from its original Polygon CDK blueprint over to the OP Stack architecture, officially linking the blockchain into Optimism's interconnected global Superchain ecosystem.

The Gas Layer: X Layer uses the native OKB token as its primary fuel source to clear transactions, completely phasing out older legacy tokens (like OKT) to secure a fixed maximum supply structure.
XKO Address Innovation: To shield Web3 wallet participants from address poisoning and copy-paste clipboard exploits across similar EVM layers, the network utilizes a specialized XKO-prefix address format. This distinct visual design ensures instant network recognition on-chain, lowering human transmission errors while maintaining full underlying compatibility with traditional Ethereum-style addresses.
