The Ethereum Layer 2 ecosystem grew and splintered. Arbitrum’s TVL increased 70% year-over-year to $10.4 billion. Optimism more than doubled to $5.6 billion. Base, launched in 2023, crossed $4.7 billion. Today, 67.5% of Uniswap’s daily volume runs on Layer 2 networks.
The infrastructure worked, but fragmentation followed. Every new network became an isolated liquidity pool. Every cross-network product required the same stack: custom execution logic, wrapped token contracts, third-party liquidity with no guarantee of depth. For most teams, that meant months of infrastructure work before shipping a single user-facing feature.
The industry’s architectural response has been Intents-based execution, where users specify desired outcomes (like “trade my BTC for ETH”) rather than specific routes. As documented in DL Research’s State of DeFi 2025, intent-based protocols collectively scaled to billions in monthly volume over 2025. The same abstraction logic changing how traders execute is now changing how developers build.
SODAX is a cross-network DeFi platform built on Sonic that packages this model as an SDK. Its Solver (the routing and execution engine coordinating cross-network actions) is backed by $6M+ in Protocol-Owned Liquidity across 17+ networks. Developers access the full stack through a single integration point, the SODAX SDK, and typically go live in about a week.
The third major version of the Solver, launched in early February, brought 100,000 requests-per-second capacity. It has since processed nearly 6,000 cross-network intents, routing $6.45M in volume. As we described previously, SODAX is designed to behave predictably as network conditions change, coordinating execution under real-world constraints.
Here’s how production teams, from Layer 2s to wallet apps, are using the SODAX SDK to ship cross-network features in days rather than months.
radFi: cross-network execution with native Bitcoin
Bitcoin is the deepest capital pool in crypto and the most technically constrained environment for DeFi execution. The Bitcoin mainnet has no EVM, no general-purpose smart contracts, and no native interoperability with external networks.
Most protocols sidestep the problem by wrapping BTC into a synthetic representation on another network, which introduces custodial risk and bridge dependency.
radFi, a Bitcoin AMM protocol built on Casey Rodarmor’s Light Pools concept, executes trades entirely on Bitcoin mainnet for BTC and runes with an approach that exponentially accelerates settlement speed.
Bringing cross-network capability to that environment means coordinating between Bitcoin’s UTXO model and the account-based architectures of networks like Ethereum and Solana, handling asymmetric finality times, and sourcing liquidity across fundamentally different systems.
But users never need to leave the Bitcoin-native experience.
“Bringing native BTC trading directly against assets like ETH and SOL isn’t just an incremental improvement. It’s a new primitive,” said Scott Smiley, co-founder of radFi. “This integration sets the foundation for the fastest native BTC-to-anything trading experience in the industry.”
The recently announced SODAX SDK integration gave radFi access to cross-network execution across 17+ networks through a single integration point. Users express an intent (trade native BTC for native ETH, SOL, or USDC) and the Solver coordinates the cross-network path, sourcing liquidity and settling natively on both sides. No wrapped tokens, intermediary contracts, or multi-step user flows.
Most cross-network Bitcoin trades require at least one full block confirmation, which takes an average of 10 minutes on the Bitcoin network and can rise with network congestion.
The radFi-SODAX integration instead requires zero block confirmations, achieving finality at the moment of broadcast through radFi’s trading infrastructure.
In testing, trades have settled in under one minute. By comparison, leading alternatives for native Bitcoin trading clock in at 27 minutes for the same route.
Three routes are live at launch, pairing Bitcoin with Ethereum, Solana, and USDC, with additional cross-network routes to follow.
Houdini Swap: privacy & execution at scale
For Houdini Swap, a privacy-focused DEX routing trades across more than 50 liquidity sources, the core challenge is competitive pricing across fundamentally different virtual machine environments.
Connecting EVM-compatible networks with Solana (Rust) and Sui (Move) traditionally requires maintaining separate, highly complex codebases and routing logic for each environment.
Integrating the SODAX SDK gave Houdini Swap access to the Solver across all supported networks simultaneously. Users declare their intents, and the Solver matches them to the most reliable execution path available.
The production numbers reflect sustained throughput: 600 to 1,000 cross-network trades processed daily, with $1.5M to $2.5M in daily volume routed through SODAX over the past 30 days. This demonstrates what the SDK is built for: infrastructure that holds under real production load.
LightLink: bootstrapping Layer 2 liquidity
Every new Layer 2 network faces the same cold-start problem. Deep accessible liquidity attracts DeFi protocols and users. But building, auditing, and securing proprietary cross-network execution infrastructure consumes months of engineering capital before a single user arrives.
LightLink is a gasless Ethereum Layer 2 backed by $11.5M in funding, with over 100 million blocks processed and 40 million transactions handled. With 50+ ecosystem partnerships including Animoca Brands and Lamborghini’s Fast ForWorld platform, it had ecosystem momentum but needed cross-network liquidity from day one.
Instead of dedicating months to proprietary bridge development, LightLink integrated the SODAX SDK to deploy native representations of major assets (BTC, ETH, and SUI) directly on their network.
Through SODAX’s architecture, assets flow through the unified liquidity system on Sonic. They are also deployed on partner networks under local naming standards: SUI.LL, AVAX.LL, appearing as native tokens to users while remaining fully composable within the SODAX ecosystem.
Rather than launching as an isolated liquidity island, LightLink connected directly into a cross-network system already covering 17+ networks. Their developers could focus on scaling their local ecosystem rather than maintaining execution infrastructure indefinitely.
“Being able to offer the variety of assets that SODAX provides means we can offer so much more for DeFi traders within the ecosystem,” said Daniel Enright, Ecosystem Lead at LightLink.
“They don’t need to leave the network to gain exposure to other assets. It’s better in all aspects through SODAX because of the deep liquidity they offer across all the networks they support.”
Amped Finance: fast deployment of complex mechanics
Amped Finance is a derivatives DEX built on LightLink and Sonic, giving traders exposure to cross-network assets (BTC, SOL, and AVAX) without forcing them to leave their network.
Previous attempts using third-party execution solutions hit consistent walls: 24-hour settlement delays, insufficient liquidity depth, and slippage that made the product uncompetitive.
Building cross-network index pools and derivatives products from scratch would have meant months of complex coordination across networks, continuous state monitoring, and automated rebalancing.
The SODAX SDK handled the underlying infrastructure. It provided a single integration point that managed complex cross-network execution and immediate access to $6M+ in Protocol-Owned Liquidity across BTC, ETH, SOL, SUI, and AVAX.
After just two weeks to complete the SDK integration, they deployed a full cross-network Money Market live in 2 to 4 days. The SDK also unlocked a new product category entirely (cross-network index pools).
It allowed users to gain diversified exposure to multiple assets across ecosystems through a single-token position. Amped now processes $1M+ in monthly DEX volume and generates $4.4M in protocol fee revenue.
For Amped, the SDK removed the barrier between idea and shipping. What would have required a dedicated infrastructure buildout became a two-week integration, with new product categories unlocked as a result.
Hana Wallet: turning infrastructure into user experience
Wallet teams sit at the front line of cross-network complexity. When a user wants to move assets from Ethereum to an alt-L1, traditional options are poor: route them through a cumbersome third-party interface or maintain separate integrations for every network.
The former exposes users to wrapped asset confusion, manual network switching, and managing secondary gas tokens. The latter consumes engineering capacity indefinitely.
Hana Wallet (with 47,000+ installed users and integrations with Mastercard and MoneyGram) integrated the SODAX SDK to deliver in-app cross-network trades. The Solver handles routing and settlement, coordinating execution across networks.
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. For a wallet team, that’s the clearest signal that abstracting cross-network complexity with the SODAX SDK translates directly to product outcomes.
How SODAX coordinates liquidity
What makes these integrations fast and reliable in production is SODAX’s cross-network execution and liquidity system. When developers integrate the SDK, they gain programmatic access to baseline Protocol-Owned Liquidity deployed across BTC, ETH, SUI, and other major assets.
Plus there’s automatic routing across major external DEXs including Uniswap, Cetus, Raydium, and PancakeSwap.
Traditionally, each liquidity source would require a separate custom integration, maintained independently across different networks. The Solver optimizes across all of them automatically, without developer overhead. One integration point opens the full ecosystem.
Solver v3, launched in early February, raised the infrastructure ceiling significantly: 100,000 requests per second capacity, designed to scale with partner demand without requiring teams to rearchitect as volume grows.
“Developers shouldn’t need an entire engineering process to add cross-network deposit functionality,” said Min Kim, SODAX’s founder. “Our SDK should make that a single line of code.”
Build the future, skip the infrastructure
The fragmented, execution-heavy development model is giving way to something more composable. What the teams above have in common is that they shipped products that weren’t viable before.
Derivatives exposure without settlement delays, native liquidity on a new L2 from day one, wallet trades that settle in under 30 seconds across any supported network.
“As new networks keep emerging, fragmentation is only accelerating, and there aren’t enough players on the interoperability side to service all of them,” Kim said. “If our thesis plays out the way we believe it will, SODAX is here to meet that demand.”
The SODAX SDK provides the unified liquidity and execution foundation to do it at production scale, without building or maintaining the underlying infrastructure yourself.
It doesn’t matter whether you’re bootstrapping a new Layer 2 network, deploying complex derivatives infrastructure, or designing the next generation of cross-network wallet experiences.
