What Are SODAX and the SODAX SDK?

Kaia × SODAX

Kaia's ecosystem now supports cross-network execution through the SODAX SDK integration. This means Kaia developers can connect their applications to 17+ networks, including Ethereum, Solana, and Sui through a single integration point, without building custom infrastructure for each chain. Here's what SODAX brings to the table and how to get started.

TL;DR

• The SODAX SDK gives developers on Kaia a single integration point for cross-network execution, unified liquidity, and lending across 17+ networks.
• Kaia builders can offer their users access to assets on Ethereum, Solana, Sui, Arbitrum, and more without building custom infrastructure for each network.
• Production teams like Houdini Swap, Amped Finance, and Hana Wallet have already shipped cross-network products using the SODAX SDK in under two weeks.

Building DeFi products that work across multiple networks has historically meant months of infrastructure work. Every new network requires custom execution logic, bridge integrations, liquidity sourcing, and ongoing maintenance. For teams building on Kaia, the challenge is the same: how do you give users access to assets and liquidity across Ethereum, Solana, Sui, and other ecosystems without building it all from scratch?

The SODAX SDK is the answer to that question. SODAX is a cross-network execution and liquidity system that coordinates financial actions across networks through a solver-based model, integrated money market, and unified liquidity. The SDK packages that entire system into a single integration point that developers can plug into their applications.

Instead of stitching together separate integrations for each network, developers integrate the SODAX SDK once and gain programmatic access to cross-network execution across 17+ networks. That includes EVM networks like Ethereum, Arbitrum, Base, BNB Chain, Optimism, and Polygon alongside non-EVM environments like Solana, Sui, Stellar, and Injective. Kaia is now part of that network.

A typical SODAX SDK integration takes about one week from exploration to deployment.

What DeFi Primitives Does the SODAX SDK Provide?

The SODAX SDK is not limited to token exchanges. It exposes a full stack of cross-network DeFi primitives that developers can compose into products their users actually need.

Cross-Network Execution

Users express an Intent, a structured request defining the desired outcome and constraints. The Solver, SODAX's routing and execution engine, evaluates available paths across all 17+ networks and selects the most reliable execution route. The developer does not need to manage routing logic, gas estimation across networks, or finality differences between EVM and non-EVM environments.

Unified Liquidity

The Solver draws from Protocol-Owned Liquidity deployed across major assets like BTC, ETH, SUI, and AVAX. It also routes through external DEXs including Uniswap, Cetus, Raydium, and PancakeSwap. Traditionally, each liquidity source would require a separate custom integration maintained independently across different networks. One SODAX SDK integration opens the full ecosystem.

Cross-Network Lending and Borrowing

The SODAX Money Market lets builders lend, borrow, and reuse capital across all integrated networks. With 20 assets available for lending and borrowing, developers can offer their users cross-network collateral positions without requiring manual repositioning of assets.

How SODAX Handles Cross-Network Liquidity

Liquidity fragmentation is one of the core challenges in cross-network DeFi. Capital sits in isolated pools across dozens of networks. A developer building on Kaia might need access to Ethereum liquidity for one user and Solana liquidity for another. Without unified infrastructure, that means maintaining separate integrations, monitoring multiple liquidity sources, and handling the operational complexity of each network's unique execution model.

SODAX treats liquidity as a unified, globally accessible inventory rather than isolated pools. When a user on Kaia initiates a cross-network action, the Solver evaluates liquidity across all 17+ integrated networks simultaneously. It considers Protocol-Owned Liquidity, external DEX liquidity, and available execution paths to find the most reliable route.

The Solver v3, launched in early 2025, brought 100,000 requests-per-second capacity. This means the infrastructure scales with partner demand. As Kaia's ecosystem grows and more developers ship cross-network products, the execution system can handle the throughput without requiring teams to rearchitect their integrations.

The networks currently integrated include Sonic (SODAX's hub network), Ethereum, Arbitrum, Base, BNB Chain, Optimism, Polygon, Avalanche, Solana, Sui, Stellar, HyperEVM, LightLink, ICON, NEAR and Kaia.

Can I Integrate a Cross-Network SDK in Under Two Weeks?

Yes. Multiple production teams have demonstrated that the SODAX SDK integration timeline is measured in days, not months. Here is what real teams have shipped and how quickly they did it.

Houdini Swap: Scaling Cross-Network Volume

Houdini Swap, a privacy-focused DEX routing trades across more than 50 liquidity sources, integrated the SODAX SDK to connect EVM-compatible networks with Solana and Sui without maintaining separate codebases for each environment. The result: 600 to 1,000 cross-network trades processed daily, with $1.5M to $2.5M in daily volume routed through SODAX over sustained periods.

LightLink: Day-One Liquidity for a Growing Layer 2

LightLink, a gasless Ethereum Layer 2 backed by $11.5M in funding, faced the classic fragmentation problem. Deep liquidity attracts protocols and users, but building proprietary cross-network execution infrastructure consumes months of engineering time. Instead of building from scratch, LightLink integrated the SODAX SDK to deploy native representations of BTC, ETH, and SUI directly on their network - with trading liquidity attached. Rather than launching as an isolated liquidity island, LightLink connected into a cross-network system already covering 17+ networks from day one.

Amped Finance: Complex Products in Days

Amped Finance, a derivatives DEX on LightLink and Sonic, completed their SODAX SDK integration in two weeks. They then deployed a full cross-network Money Market in 2 to 4 days. The SDK also unlocked cross-network index pools, a product category that would have required months of dedicated infrastructure work to build independently. Amped now processes $1M+ in monthly DEX volume.

Hana Wallet: 9x Growth After Integration

Hana Wallet, with 47,000+ installed users and integrations with Mastercard and MoneyGram, integrated the SODAX SDK to deliver in-app cross-network trades. Trades execute across any supported network in under 30 seconds, with no wrapped tokens and no network switching required. Following integration, Hana Wallet's weekly top-up volume surged nearly 9x within weeks.

What Does This Mean for Kaia Developers?

With the SODAX integration now live on Kaia, builders in the Kaia ecosystem gain immediate access to the full SODAX stack. That means a wallet app on Kaia can offer users direct access to ETH on Ethereum, SOL on Solana, or SUI on Sui without building separate integrations for each network. A lending protocol can accept cross-network collateral. A DEX can source liquidity from every network SODAX supports.

Live trading pairs are already live on sodax.com, including native KAIA, USDT, and bnUSD. As the Kaia ecosystem expands, additional routes and asset pairs will follow.

The integration pattern follows what LightLink, Houdini Swap, and other partners have already proven: integrate once, access all networks, and ship cross-network products in days rather than months.

How to Start Building with the SODAX SDK

Getting started as a Kaia developer follows three clear paths.

1. Explore the Partners Page

The SODAX partners page showcases live integrations and case studies. Study how teams like Houdini Swap, LightLink, Amped Finance, and Hana Wallet approached their integrations. Each case study details the specific cross-network features shipped, the timeline, and the production outcomes. This is the best starting point for understanding what is possible.

2. Read the SDK Documentation

The SODAX SDK documentation at docs.sodax.com provides technical guides, API references, and code examples. The documentation covers everything from basic cross-network execution to advanced use cases like Money Market integration and sodaVariant deployment. For Kaia-specific implementation details, the documentation includes network-specific configuration guidance.

3. Use the Builders MCP

The SODAX Builders MCP is a developer tool that gives AI coding assistants live access to SODAX API data and auto-updating SDK documentation. It works with Claude, Cursor, VS Code, Windsurf, and other MCP-compatible agents. Instead of manually searching documentation, developers can query the MCP server for integration guidance, code examples, and live network data directly within their development environment to get an MVP release live.

Frequently Asked Questions

How long does a SODAX SDK integration take?

A typical integration takes about one week from exploration to deployment. Some teams have shipped full cross-network products, including Money Markets and index pools, within two weeks of starting their SDK integration.

Does the SODAX SDK support non-EVM networks?

Yes. The SDK provides a unified interface across both EVM and non-EVM environments. Developers on Kaia can access liquidity on Solana, Sui, Stellar, and more without writing Rust, Move, or Stellar-specific code. The Solver handles the cross-environment coordination.

What is the difference between the SODAX SDK and a bridge?

A bridge moves assets between two networks. The SODAX SDK provides full cross-network execution infrastructure. Users express an Intent (swap native SOL for native KAIA) and the Solver coordinates the entire execution path. This includes routing, liquidity sourcing, and settlement across any combination of the 17+ supported networks. No wrapped tokens, no manual network switching, and no separate bridge transactions.

Build What Was Not Possible Before

The teams that have integrated the SODAX SDK shipped products that were not viable before: derivatives exposure without settlement delays, native liquidity on a new Layer 2 from day one, wallet trades that settle in under 30 seconds across any supported network. Kaia developers now have access to the same infrastructure.

As new networks continue to emerge and liquidity fragments further, the need for unified cross-network execution grows. The SODAX SDK provides that foundation without requiring you to build or maintain the underlying infrastructure yourself.
