MetaMask Adds OKX DEX Support with New MEV Protection

• MetaMask now integrates OKX’s DEX API, enabling faster swaps with lower slippage across 500 DEXs on 25 networks.
• MEV protection via Servo is now active, making MetaMask the first third-party wallet to implement it through a partnership with OKX.

MetaMask has finally officially partnered with OKXpartnered with OKX, and the results are impressive. Through this partnership, MetaMask has now integrated OKX’s DEX API into their swap feature.

For users, this means swaps are much faster, cheaper, and safer. Access is also wider—over 500 DEXs across 25 blockchain networks are immediately available. Execution time? Less than 100 milliseconds. Slippage? Much reduced. For those who often bite their fingers because of the price difference when swapping, this is good news.

Let's build together

We’re joining forces with @Consensys to upgrade @MetaMask swaps with our DEX API and bring enhanced MEV protection to #Wallet via Servo.

MetaMask Boosts Security with First-Ever Servo Integration

However, what makes this partnership even more interesting is not just its performance. MetaMask and OKX Wallet are now equipped with a protection system against MEV (Maximal Extractable Value) attacks thanks to a technology called “Servo.”

This technology is not an ordinary feature—it is protection specifically designed to ward off front-running and sandwich attacks, two things that often cause users’ swaps to be “swept” by bots before the transaction actually takes place. And interestingly, this is the first time Servo has been used in a third-party wallet.

On the other hand, in May, MetaMask released the Smart Accounts feature that allows users to make batched transactions, pay for gas with tokens other than ETH, and even prepare advanced features—all without having to change addresses or transfer funds. Simply update to the latest version of the MetaMask Extension, and the feature is immediately active.

In the same month, as we previously reported, MetaMask also officially added full support for the Solana network via their browser extension. This means that tokens on Solana can now be managed directly from MetaMask, without having to use a separate wallet. Most conveniently, security features such as transaction simulations and DApp risk warnings also automatically apply to Solana accounts.

Furthermore, as we have covered, in March MetaMask also integrated the Crypto Tax Calculator into its platform. This is a simple solution for those who are confused about managing crypto taxes. This tool helps users generate automatic tax reports for 23 jurisdictions, with support for multiple wallets and automatic transaction tracking. No need to open five different sites just to find out how much to report to the tax office.

A New Era of Wallet Performance and Protection Begins

In terms of volume, OKX Web3 Wallet currently records daily transactions of $140 million with around 75,000 active users per day. Meanwhile, MetaMask Swap is still around $7 million per day. But with the additional performance from OKX and MEV protection from Servo, this number could change quickly. Moreover, users are increasingly aware of the importance of efficient swaps that are free from bot interference.

It should also be noted that this collaboration comes after OKX tightened their security side. Some time ago, they were the target of attention due to the activities of hacker groups such as Lazarus. Since then, OKX has moved quickly: collaborating with CertiK, Hacken, and SlowMist for audits, and activating a bug bounty system. It makes sense that they are now MetaMask’s strategic partners to improve user security.

Interestingly, this collaboration does not end here. According to Consensys, this collaboration is only in its early stages. In the future, they plan to explore further—perhaps expanding to Layer-2 networks such as Linea. If true, it means that the experience of using a wallet could be much more agile, secure, and… yes, not inferior to traditional trading platforms, but still self-custody.
