The multichain world is here to stay, but it has introduced a fundamental challenge: liquidity fragmentation. Users and businesses alike are forced to maintain balances across multiple blockchains, constantly bridging, rebalancing, and shouldering unnecessary operational costs.
At RockawayX, with our dedicated solvers team providing support to projects like deBridge and Mayan, having also collaborated with Wormhole on the development of Wormhole Settlement, we’re no strangers to multi-chain balances and the pains of constant rebalancing.
With Circle Gateway now live on mainnet, this challenge is being meaningfully addressed head-on for USDC. Gateway creates a unified USDC balance that can be instantly deployed across supported blockchains, removing the friction of pre-positioning liquidity.
We’re proud to have played a supporting role in Gateway’s journey from testnet to mainnet. We view Gateway as a critical advancement for the next phase of crypto adoption—one that directly benefits solvers, builders, and liquidity providers.
Moving forward, our team will leverage the system in our solvers activities, maintaining one cross-chain USDC balance to instantly pull funds from for the supported chains that we operate on, boosting capital efficiency while enabling us to process larger orders on smaller chains where we typically wouldn’t park significant capital.
Why Gateway Matters
Capital efficiency has long been the limiting factor for onchain markets. Today, solvers—the backbone of efficient transaction execution across chains—must hold fragmented liquidity to ensure reliability. This redundancy reduces efficiency and raises costs.
Circle Gateway resolves this by making USDC truly chain-agnostic. Instead of idle balances locked across ecosystems, solvers and applications can draw instantly from a unified pool. For the first time, capital can flow freely without the latency, risk, and expense of bridging.
From a broader market perspective, this unlocks:
- Instant access to liquidity on any supported chain
- Reduced operational overhead for businesses
- Improved user experiences, where applications abstract away the complexity of multichain infrastructure
With the launch of Gateway mainnet, the system is now live on Arbitrum, Avalanche, Base, Ethereum, Optimism, Polygon, and Unichain, with more blockchains going live in the near future.
RockawayX’s Role In Shaping Gateway
During early testing, our team provided feedback that shaped the protocol, including requests for greater visibility into in-flight deposits, pointing out inconsistencies in the API documentation, and clarifying technical details around fees. We also participated in conversations about how Gateway improves solver operations and agreed to contribute to forthcoming research measuring the cost savings it enables.
Now, as Gateway launches on mainnet, we are among the first to integrate it into our solver infrastructure. Instead of holding fragmented balances across chains—$100k here, $200k there—we will maintain a unified USDC balance that can be pulled instantly to any supported chain. This has two transformative effects: it dramatically improves capital efficiency, and it allows us to process large orders (up to $1M) on smaller chains where we would never otherwise provision that level of liquidity.
Our View On The Future
This integration reinforces conviction in leveraging solvers as a hidden backbone of DeFi to improve scalability and overall user experience across intents-based applications. By adopting innovations like Gateway early, we’re working to demonstrate how solvers can operate with greater competitiveness, efficiency, and scale, providing deeper liquidity and faster execution across the multichain ecosystem.
We believe Gateway represents an essential tool in the maturation of the onchain experience—fragmented balances and operational inefficiencies cannot persist. For institutional adoption to accelerate, liquidity must be accessible instantly, anywhere.
RockawayX is proud to have supported Circle in testing and refining Gateway, and we’re excited to bring this innovation into production and continue to support through our solver infrastructure.
