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.

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.
