Cross-chain Execution, solved by SODAX with intents

We are preparing to enter a new DeFi era with our Unified Liquidity Layer, powered by intent-based execution and Protocol-Owned Liquidity (POL). One of the most transformative components is the SODAX Solver — a powerful, intent-based engine that sits at the heart of our platform. It’s designed to solve two of DeFi’s most persistent problems: fragmented liquidity and clunky user experience. Here we unpack how Solvers work, where they fit in the SODAX stack, and why they’re a game-changer for DeFi users and developers.

What Is Intent-Based Execution?

Traditional DeFi asks the user to interact directly with liquidity pools — managing gas, slippage, and routing themselves. That complexity doesn’t scale. Intent-based execution flips this model.

Instead of micromanaging how a trade is performed, the user simply submits an intent: "I want X amount of Token A in exchange for Y amount of Token B.” From there, SODAX's Solver handles the execution by searching across the cross-chain DeFi landscape to deliver the best possible result.

How SODAX solves your swap

Behind the scenes, the Solver:

Scans connected AMMs like Uniswap, Raydium, Cetus, Soroswap, and others.
Determines the optimal trade route and ensures the user’s intent can be filled.
If the requested price can’t be met, the latest version of the Solver will automatically hold the trade as a limit order, completing it once the market price aligns.
The user receives exactly what they asked for — seamless, fast, and slippage-free.
Any arbitrage found or created by the Solver will even be passed on to the user as a better swap rate.

You’re not dealing with approvals, failed transactions, or front-running. The Solver manages that complexity for you and you can access all the assets you want from one cross-chain DeFi protocol. Simply, SODAX Solvers remove the noise and lets users focus on what they care about. Outcomes.

Protection from Slippage and MEV

Slippage and MEV (Maximally Extractable Value) attacks are common pain points in DeFi swaps, resulting in the user not getting the swap they asked for. With SODAX the user is shielded from these issues as they interact directly with the Solver, not with public AMM pools. the Solver can:

Predict and avoid MEV strategies in real time.
Minimize slippage through smarter routing.
Bundle the trade with internal arbitrage (if needed) to maintain optimal pricing.

This makes trading through SODAX not only more efficient but fundamentally safer than most existing methods. The user knows exactly what they can expect upon creating an intent, the solver simply delivers the outcome to them.

Post-Trade: Rebalancing and Capital Efficiency

After the user’s trade is fulfilled, the Solver goes to work in the background. It rebalances liquidity — restocking itself through cross-chain routes to prepare for the next trade. In the past, this was fueled by ICON’s Network-Owned Liquidity (NOL). This system proved effective but with assets inactive and held by the Solver, there were limitations in scale and efficiency.

Enter Protocol-Owned Liquidity (POL)

With SODAX, this model is evolving. Previously held NOL will be progressively migrated to Sonic along with our DeFi infrastructure.

Instead of passively holding assets, POL is now actively deployed in a single-sided Money Market. As with NOL, this market will hold a wide range of cross-chain assets across our integrated chains. When a trade needs to be executed, the Solver borrows from this pool, completes the trade, then rebalances and repays the loan quickly and efficiently.

This setup provides:

More scalable capital access for the Solver.
Passive yield for POL and community asset suppliers through the Money Market.
No idle capital, improving overall efficiency.

The Developer Edge: SODAX Core SDK

Beyond users, projects and protocols can tap into this infrastructure directly, with the SODAX Core SDK giving any DEX, bridge, or aggregator the ability to:

Use the SODAX Solver’s intent-based execution.
Access POL liquidity, and AMMs across integrated chains.
Deliver leading swap rates and faster settlement to their users.

This creates a B2B distribution flywheel — allowing SODAX's liquidity and Solver engine to connect the wider DeFi ecosystem seamlessly. For more on how SODAX solves cross-chain developer experience — Read our blog on the SODAX SDK.

Clean, Predictable DeFi

SODAX is refreshing DeFi, abstracting away the pain points of cross-chain trading to bring users a seamless experience powered by a capital-efficient, deeply integrated backend. Pushing the space forward to become more accessible for everyone:

No slippage management or manual routing.
No surprise MEV losses.
One interface, one request, one result.
Whether you're swapping tokens on Avalanche or SUI, the experience is identical.

As liquidity spreads across more chains and DeFi gets even more complex, intent-based execution with SODAX Solvers is how to stay ahead. Delivering fast, scalable, and chain-agnostic DeFi solutions for all.
