1inch and OKX partner to power OKX Wallet and OKX DEX with 1inch APIs

OKX, a global Web3 technology company, now integrates the 1inch Swap and 1inch Fusion APIs to offer seamless swaps on OKX DEX and OKX Wallet.

Committed to delivering cutting-edge solutions, OKX has integrated the 1inch Swap and Fusion APIs, enhancing users’ swapping experience with the best rates, deeper liquidity, and advanced security features. OKX Wallet will also be supported by the 1inch dApp, offering users access to a broad range of onchain tools.

OKX Wallet provides users with a secure and convenient way to store, manage, and trade various digital assets across multiple blockchain networks. It supports a wide range of cryptocurrencies and offers access to a range of dApps, combining user-friendly features with robust security measures.

At the heart of this integration are the 1inch Swap API and 1inch Fusion API, two powerful tools that optimize every aspect of the crypto swapping process. OKX Wallet and DEX users can now enjoy seamless, secure swaps backed by 1inch’s cutting-edge solutions. Let’s explore how these APIs transform the OKX Wallet and OKX DEX experience.

The 1inch Swap API: optimal rates and routes
The 1inch Swap API enables fast, self-custodial swaps across multiple major DeFi ecosystems. What sets this API apart is its ability to provide users with the best possible rates and the most efficient swap routes. The Swap API optimizes gas costs and swap execution by finding the most efficient paths across different liquidity pools.

The 1inch Fusion API: flexible and secure swapping
With the 1inch Fusion API, OKX Wallet and OKX DEX users experience new levels of flexibility and efficiency in their swaps. Here’s what the Fusion API brings to the table:

Gasless swaps: users don’t need to hold network tokens like ETH to cover swap fees — resolvers (professional market makers) take care of the fees, making transactions smoother and more convenient.
MEV protection: users are safeguarded from front-running and sandwich attacks by design, adding a crucial security layer.
Customizable swaps: with the ability to set custom price and time ranges, users can fine-tune their swaps to better match their preferences and goals.
Together, the 1inch Swap and Fusion APIs deliver a comprehensive toolkit that enhances the swapping experience for OKX Wallet and OKX DEX users, no matter the amount being traded.

A partnership driving innovation
“At OKX, we are dedicated to building a powerful and user-friendly Web3 wallet that enhances the DeFi experience,” says Jason Lau, Chief Innovation Officer at OKX. “By integrating 1inch’s Swap and Fusion APIs, OKX Wallet users can now enjoy seamless, gasless swaps with optimal rates and built-in MEV protection. This integration is a testament to our commitment to providing users with secure, efficient, and innovative tools that simplify their journey into the world of decentralized finance.”

OKX’s integration of 1inch APIs reflects its ongoing commitment to innovation and user satisfaction. With the 1inch Swap and Fusion APIs, users can now benefit from Fusion’s powerful features in a safer, more secure environment, ensuring the best possible swapping experience.

You can enhance swap efficiency in your project with cutting-edge 1inch APIs available on the 1inch Developer Portal.

The release of the white paper comes at a time of growing interest in addressing key challenges faced by existing cross-chain solutions.

In a world where Vitalik Buterin himself has warned of risks associated with centralized cross-chain solutions, 1inch offers a future-proof model that aligns with the values of Web3 and DeFi.

Interoperability across blockchains has been a hot topic for years, but so far, solutions have often been clunky, centralized or downright inconvenient. Now, 1inch is here to change that.

Cross-сhain frictions
In today’s decentralized finance (DeFi) ecosystem, limited interoperability between blockchain networks has created massive friction. The existing solutions generally fall into two categories: centralized bridges that come with serious security risks or decentralized approaches that often offer a frustrating user experience.

Even emerging intent-based approaches, like those described in the Anoma blog research, simplify liquidity sourcing but still demand user involvement in off-chain order signing, adding another layer of complexity to cross-chain swaps. For DeFi to reach the next level, a more seamless, secure, and user-friendly solution is needed.

1inch’s solution: the best of both worlds
To address these challenges, 1inch came up with Fusion+, an intent-based atomic cross-chain swap protocol. This groundbreaking hybrid solution combines the best aspects of traditional atomic swaps and intent-based protocols. If you’ve been following DeFi for a while, you know how powerful atomic swaps can be for trustless exchanges. But let’s face it — they’re not the most user-friendly. They require users to generate secret values and actively participate in the swap process, which isn’t exactly “plug-and-play.”

On the flip side, intent-based protocols simplify liquidity but demand user involvement in off-chain signing, which still adds layers of friction. 1inch’s team has engineered a solution that combines the security of atomic swaps with the simplicity of the intent-based approach.

The secret sauce: how 1inch does it better
So, what’s the secret sauce that makes 1inch’s new protocol stand out? It’s Fusion+, which not only enhances security but also makes the user experience frictionless. Instead of relying on users to manage every aspect of a swap, the process is streamlined through the use of Dutch auctions and 1inch resolvers — trusted professional market makers that automate the bulk of the work.

Here’s how it works:
Dutch auctions ensure users get the best rates possible, as resolvers compete to fill orders at the most favorable terms.

Resolvers are incentivized to execute swaps quickly and securely, stepping in to ensure that if either party becomes unresponsive, the transaction is still completed.

By maintaining the core components of atomic swaps — hashlocks and timelocks — the protocol ensures trustless, operator-free exchanges across multiple blockchains.

Building the future of DeFi
In simple terms, 1inch is solving one of the biggest bottlenecks in DeFi adoption: cross-chain friction. With more users and liquidity flowing into DeFi every day, the need for a seamless cross-chain experience has never been greater. 1inch’s protocol doesn’t just address this need — it takes it to the next level, making cross-chain swaps as easy as making a trade on a single blockchain.

This solution is launching at a critical time, too. Ethereum founder Vitalik Buterin has repeatedly spoken about the challenges of achieving true decentralization in cross-chain systems, citing concerns about censorship and security. 1inch Fusion+ tackles these concerns head-on, offering a decentralized, secure, and user-friendly solution that aligns with Vitalik’s vision for the future of blockchain interoperability.

A journey of cross-chain innovation
1inch’s commitment to advancing cross-chain functionality is not new. This white paper builds on intent-based protocols such as the 1inch Limit Order Protocol and Fusion, and other existing technologies is paving the way for a truly interoperable DeFi future. If you’ve been following 1inch’s journey, you know they’ve been steadily working towards this moment, and this white paper marks a major milestone.

Check out some of our previous posts to dive deeper into our cross-chain research.

The future of DeFi starts now
For anyone deep in the crypto trenches, it’s clear: cross-chain interoperability is essential for DeFi to truly go mainstream. In line with 1inch’s vision, the barriers between blockchains are about to become a thing of the past. 1inch Fusion+ isn’t just another incremental improvement — it’s a paradigm shift that will unlock new possibilities for traders, liquidity providers and developers alike.

As 1inch continues to push the envelope, this white paper represents more than just a technical document — it’s a vision for the future of decentralized finance. Whether you’re a hardcore DeFi user or just starting to explore the possibilities of cross-chain swaps, this is the protocol to watch.
