The world of blockchain and digital assets is constantly evolving, and one of the most user-centric upgrades in recent times is the introduction of dual address support on OKX. With the launch of the EVM (Ethereum Virtual Machine) compatibility layer, OKTC now supports Ethereum-style address formats — making interoperability smoother and user experience more seamless than ever before.
This innovation allows users to generate two addresses from a single private key: one starting with ex, and another starting with 0x. Both addresses share the same balance and can be used interchangeably for transactions such as sending, receiving, and interacting with decentralized applications (dApps). This dual-address system bridges the gap between legacy systems and modern wallet standards.

How Dual Address Works
At its core, the dual address feature leverages cryptographic consistency across different address formats. When you create a wallet on OKX or compatible platforms:
- Your private key generates a public key using elliptic curve cryptography.
From this public key, two representations are derived:
- The original
ex-prefixed address, native to OKTC. - The
0x-prefixed address, compatible with Ethereum and ERC-20 standards.
- The original
Despite their different appearances, both addresses point to the same underlying account. Any funds sent to either address are instantly accessible via the other. This eliminates the need for manual bridging or wrapping assets when switching between ecosystems.
For example:
- You receive USDT on your
ex...address from an OKX internal transfer. - Later, you use MetaMask — which only recognizes
0x...addresses — to interact with a DeFi protocol. - Since MetaMask connects to the same private key, it automatically detects the balance from the shared account.
This unified balance model enhances convenience while reducing the risk of lost funds due to sending assets to incompatible addresses.
Why Ethereum Format Matters: The Role of MetaMask
One of the primary drivers behind adopting Ethereum-style addresses is compatibility with widely used tools like MetaMask. As the most popular self-custody wallet in the Web3 space, MetaMask only supports 0x-formatted addresses derived from Ethereum’s standards.
By enabling dual address functionality, OKX ensures that users aren't locked out of the broader decentralized ecosystem. Whether you're participating in NFT mints, yield farming, or cross-chain swaps, having a 0x address means frictionless integration with thousands of dApps built on EVM-compatible chains.
Moreover, developers building on OKTC benefit from reduced onboarding complexity. They can deploy smart contracts using familiar tooling (like Hardhat or Remix), test them locally, and deploy without worrying about address translation issues.
Frequently Asked Questions (FAQ)
Q: Can I have different balances on my ex and 0x addresses?
A: No. Both addresses represent the same account. The balance is shared and synchronized in real time. There’s no need to "transfer" funds between them.
Q: Do I need two separate private keys?
A: Absolutely not. Only one private key controls both addresses. Losing it means losing access to both — so keep it secure and never share it.
Q: Will all dApps recognize my 0x address automatically?
A: Most EVM-compatible dApps will recognize your 0x address if you connect through MetaMask or similar wallets. However, always verify network settings (e.g., custom RPC for OKTC) to ensure proper connectivity.
Q: Is there any fee difference when using one address over the other?
A: No. Transaction fees (gas) are identical regardless of which address format you use. Fees are determined by network activity and gas price settings, not by address type.
Q: Can I display both addresses at once in my wallet?
A: Yes. On OKX’s platform, users can view both addresses simultaneously under their wallet settings, allowing easy copying depending on use case.
Broader Implications for Blockchain Interoperability
The dual address system exemplifies a growing trend: user-first design in blockchain infrastructure. Instead of forcing users to adapt to technical silos, platforms like OKX are removing friction through backward-compatible innovations.
This move aligns with larger industry goals of achieving true cross-chain interoperability, where assets and identities flow freely across networks without complex bridges or third-party custodians.
Keywords naturally integrated throughout this article include: dual address, EVM, MetaMask, OKTC, 0x address, ex address, blockchain interoperability, and private key — all central to understanding modern wallet evolution.

Expanding Your Digital Asset Toolkit
Beyond dual addressing, OKX offers a comprehensive suite of services that empower traders and developers alike:
Spot Trading (Coin-to-Coin Exchange)
Spot trading allows direct exchange of one digital asset for another — such as swapping BTC for ETH or USDT for OKB. These trades occur instantly at market prices and form the foundation of most crypto portfolios.
OKX supports multiple spot markets including:
- Stablecoin pairs (e.g., USDT, USDⓈ)
- Major cryptocurrencies (BTC, ETH, BNB)
- Platform tokens (like OKB)
This flexibility enables efficient portfolio rebalancing and quick entry into emerging opportunities.
Graystone Concept Coins
While originally referring to Grayscale Investments’ suite of crypto trusts (such as GBTC or ETHE), “Graystone concept coins” has evolved into a broader category representing institutionally recognized digital assets. On OKX, this refers to a curated list of 11 major cryptocurrencies available for trading in a dedicated section.
These include:
- Bitcoin (BTC)
- Ethereum (ETH)
- Litecoin (LTC)
- Chainlink (LINK)
- And others backed by institutional interest
Having a dedicated zone for these assets helps traders identify high-conviction opportunities based on long-term adoption trends.
Options Contracts: Flexible Derivatives Trading
OKX also supports options contracts on key assets like BTC and ETH. Options give buyers the right, but not the obligation, to buy (call option) or sell (put option) an asset at a set price before expiration.
Key benefits:
- Limited downside risk for buyers
- Income generation potential for sellers (via premium collection)
- Hedging strategies for large holdings
Traders can choose between Simple Mode for beginners and Pro Mode for advanced users — ensuring accessibility across skill levels.
Emerging Technologies: MXC Zone & IoT Integration
Though not directly related to dual addressing, OKX’s support for innovative projects like MXC (Machine eXchange Coin) highlights its commitment to next-generation blockchain use cases.
MXC focuses on Low-Power Wide-Area Networks (LPWAN) combined with blockchain for IoT data transmission. Its core protocol enables:
- Efficient allocation of wireless bandwidth via smart bidding
- Cross-chain data marketplaces using Polkadot-based "DataHighway"
- Decentralized infrastructure for smart cities and industrial sensors
As Web3 expands beyond finance into physical systems, platforms supporting such integrations will lead the next wave of adoption.
Price Mechanisms in Derivatives: Mark Price Explained
In futures trading, OKX uses mark price to calculate unrealized PnL and prevent unfair liquidations during volatility spikes.
Mark price = Spot Index Price + Moving Average of Basis
Where Basis = (Mid Price of Futures Market) – Spot Index Price
This mechanism filters out short-term price manipulation and ensures liquidations reflect true market value rather than temporary slippage.

Final Thoughts
The introduction of dual address functionality marks a significant step toward universal accessibility in cryptocurrency. By harmonizing native (ex) and standard Ethereum (0x) formats under one private key, OKX reduces complexity for users while expanding compatibility across ecosystems.
As blockchain continues to mature, features like these will define user experience — prioritizing simplicity, security, and seamless interaction across platforms.
Whether you're a casual holder, active trader, or developer building the next dApp, understanding how dual addresses work empowers you to navigate the digital economy with confidence.
