Circle Product Management Director: The Future of Cross-Chain: Building an Interoperable Technology Stack for Internet Finance Systems

Key takeaways: Circle's 2026 vision for cross-chain interoperability, liquidity orchestration, and institutional-grade asset issuance—building the infrastructure for the internet finance system.

When the Internet was first conceived, networks operated as isolated intranets. The emergence of standardized network protocol stacks enabled reliable data exchange across systems, allowing any network to access the same set of protocols, thus spurring a massive boom in information and communication use cases.

Today, we live in a multi-chain world. Value can flow between blockchains, but its realization relies on various suppliers and inconsistent processes, and the ecosystems remain fragmented. Circle already carries a significant share of current cross-chain USDC circulation, but as more assets, applications, and institutions move onto the blockchain, the internet finance system needs an interoperability stack with reliability and scale comparable to that of the internet for open information exchange.

The first phase of building this stack focused on secure transfers . Developers tackled one of the earliest interoperability challenges: securely transferring assets between chains . Circle helped define this phase with Circle CCTP (Cross-Chain Transfer Protocol)—a leading "burn-and-mint" protocol for securely transferring USDC between blockchains. Since its launch, CCTP has processed over $140 billion in cumulative USDC transfers, supporting over 20 chains¹ , and has become a core infrastructure for wallets, exchanges, DeFi applications, and cross-chain bridge providers in the multi-chain ecosystem.

Even with improvements in cross-chain infrastructure, settlement speeds still inherently vary depending on the blockchain. Different blockchain finality models result in different wait times, user experiences, and operational constraints for developers and businesses.

Circle is addressing this challenge by building " faster-than-finality" capabilities on top of its secure CCTP foundation .

With CCTP: Fast Transfer , developers can achieve cross-chain USDC settlement in seconds, minting on the target chain without waiting for final confirmation from the source chain. This makes cross-chain value flows more predictable, improves capital efficiency, and gives USDC greater utility in diverse ecosystems.

Circle Gateway takes this a step further, providing enterprises with a unified, chain-agnostic USDC balance that can be used at speeds across 12 chains . With monthly transaction volume reaching $ 400 million and continuing to grow², the demand for instant cross-chain liquidity is accelerating. Enterprises no longer need to pre-deploy funds and manually rebalance across ecosystems; instead, they can instantly access USDC where needed.

Gateway also unlocks entirely new modes of economic activity. Through its nanopayments feature, Gateway supports gas-free USDC transfers as low as $0.000001 , allowing high-frequency trading to be efficiently settled across chains in batches. This opens the door to emerging use cases such as pay-per-request access to paid content, APIs, and data, and new models where autonomous agents can coordinate and execute computational and marketplace service transactions in real time without being constrained by traditional payment systems and fee structures.

CCTP and Gateway are working together to make settlements more predictable, capital more accessible, and cross-chain activities more efficient.

Circle has helped address USDC's liquidity fragmentation issue through CCTP's "burn-mint" infrastructure. But as more assets go on-chain—particularly RWAs such as tokenized funds, private lending, and new fiat stablecoins—the next challenge is extending the same interoperability advantages beyond USDC .

This is precisely the key to the next stage of CCTP's evolution.

Later this year , CCTP is expected to expand its "burn-mint" model from USDC to more Circle-issued assets, including EURC , USYC³ , and cirBTC , while extending these capabilities to asset issuers that partner with Circle, enabling their own digital assets to enjoy similar multi-chain distribution, interoperability, and configurable control.

This is significant in a growing multi-chain market. Asset issuers need more than just token creation; they also need infrastructure to support wider distribution, improve liquidity, and enhance asset availability .

Arc —an open Layer-1 blockchain built specifically for real-world economic activity—is a core component of this future, serving as a liquidity hub and institutional-grade environment for asset issuance and capital formation . With low and predictable fees (using stablecoins as gas), deterministic sub-second settlement finality, and a geographically decentralized set of institutional-grade validators, Arc provides an operational standard that institutional participants can confidently build upon. Arc's unique properties enable it to act as a coordination layer for issuance and liquidity routing, facilitating more efficient cross-chain economic activity.

Asset issuers can launch assets on Arc and securely extend distribution to over 20 chains via CCTP. Issuers can seamlessly manage and update asset allocations across all supporting chains from a single node on Arc. Liquidity can flow to where demand emerges in the ecosystem within seconds. This creates a flywheel effect : wider distribution drives liquidity, liquidity improves availability, and availability amplifies the network effects of assets.

In this way, Circle's interoperability strategy is expanding from solving the cross-chain experience of USDC to helping solve cross-chain issues for a wider range of new and existing digital assets.

Even with faster settlement speeds and greater liquidity, building and managing cross-chain activities remains complex. Developers today typically need to coordinate multiple transactions, signatures, gas management, target chain execution, and fee processing across different chains. These fragmented processes increase operational overhead and lead to unreliable user experiences.

To this end, Circle is investing in orchestration —a more unified way to execute cross-chain workflows, with the goal of enabling cross-chain operations to be completed with a single click.

We first built a forwarding service that automatically performs cross-chain transfers to the target chain, improving speed and reliability while reducing operational complexity. Developers no longer need to build and maintain broadcast infrastructure themselves; they only need to enable the forwarding function in CCTP, Gateway, and other supported platform services.

Building upon this foundation, Bridge Kit provides developers with a simplified approach to implement cross-chain processes through a concise SDK. Bridge Kit utilizes CCTP with built-in forwarding capabilities at the underlying level, helping developers design cross-chain application experiences with less overhead and greater reliability.

Deposit Kit is under development and aims to provide a seamless application deposit experience, including one-click cross-chain deposits, abstracting away the complexity of the underlying blockchain for end users.

Additional services such as Circle Fee Service and Circle Workflows are designed to address two of the most enduring challenges in cross-chain development: fragmented fee handling and coordination of multi-step cross-chain execution .

Circle Fee Service aims to enable quote-based cross-chain transfers by providing developers with a single pre-quoted price—a price that bundles the required fees, collects them uniformly on the source chain, and provides an accurate amount to be transferred to the target chain. This eliminates the need for multiple fee components to estimate and reconcile across services, enabling developers to handle fees in a more consistent manner and supporting a more predictable cross-chain experience.

Circle Workflows aims to coordinate multi-step, multi-chain workflows at the protocol level, transforming complex operations such as fund transfers, contract execution, and settlement into a single, unified action. Developers can define end-to-end workflows to ensure more reliable cross-chain execution, rather than relying on fragile sequential transactions that may fail midway.

These orchestration services collectively aim to reduce the number of components developers need to manage directly. The end result is a more unified, reliable, and significantly easier-to-build, integrate, and scale cross-chain experience.

Addressing cross-chain interoperability challenges involves more than just improving infrastructure; it also fosters new economic activities within the internet finance system.

For applications , it makes onboarding and depositing funds more convenient. Trading platforms such as Hyperliquid have integrated cross-chain USDC deposit functionality, reducing the complexity users typically face when transferring funds into their accounts.

For businesses operating across ecosystems , it simplifies liquidity access. Through the Gateway, USDC can be instantly accessed on all supported chains without the need for continuous pre-deployment and rebalancing of funds. Companies like RockawayX are using the Gateway to reduce liquidity fragmentation and access capital more efficiently.

For asset issuers , it creates pathways for broader multi-chain distribution. CCTP will extend Circle's interoperability model to more assets (such as RWA), while Arc provides an institutional-grade settlement layer and liquidity hub with the privacy, predictability, and operational standards required by institutional users.

For high-frequency economic activities , the Gateway supports another type of use case. AI-native platforms such as OpenMind are leveraging this infrastructure to support agency nanopayments, in which funds need to flow efficiently in extremely small amounts, without gas, and at high speed.
