Sui Network has successfully integrated Circle’s Cross-Chain Transfer Protocol (CCTP), enabling secure and seamless transfers of the USDC stablecoin between Sui and nine other major blockchain networks. This integration marks a pivotal advancement in cross-chain interoperability, empowering users and developers with frictionless asset movement across ecosystems.
With CCTP now live on Sui Bridge, USDC can be transferred one-to-one across supported chains using a native burn-and-mint mechanism—eliminating reliance on third-party liquidity providers and minimizing trust assumptions. As a result, capital efficiency improves significantly, while maintaining the stablecoin’s strict 1:1 peg to the U.S. dollar.
This development strengthens Sui’s position as a high-performance Layer 1 blockchain built on the Move programming language, offering fast finality, low latency, and scalable infrastructure for next-generation decentralized applications.
Enhanced Interoperability Through Native Cross-Chain Transfers
The integration of CCTP allows users to transfer USDC directly between Sui and the following blockchains:
- Ethereum
- Arbitrum
- Avalanche
- Base
- OP Mainnet
- Polygon PoS
- Solana
- Noble
Each transfer operates through a trust-minimized process: when USDC is sent from one chain, it is burned on the source network and instantly minted as native USDC on the destination chain. This ensures that no duplicate tokens are created and that supply remains consistent across all ecosystems.
Unlike traditional bridging methods that rely on custodians or liquidity pools—which introduce counterparty risk and potential slippage—CCTP offers a more secure and efficient alternative by leveraging cryptographic verification and decentralized messaging protocols.
“Major launch for cross chain apps and services connecting EVM, Solana and Move ecosystems via CCTP. Let the liquidity flow!”
— Jeremy Allaire, CEO of Circle
This upgrade is especially valuable for developers building cross-chain applications (dApps), as it enables native interconnectivity without requiring complex middleware or wrapper tokens.

Expanding Ecosystem Support and Developer Tooling
Beyond basic transfers, CCTP’s integration into Sui unlocks powerful use cases across finance, commerce, and decentralized infrastructure. Multiple platforms have already incorporated support for CCTP-powered USDC transfers, enhancing accessibility and functionality.
Wormhole Connect, an embeddable widget powered by Wormhole, enables frictionless cross-chain interactions directly within Sui-based applications. Similarly, Portal leverages Wormhole Connect to facilitate instant USDC transfers, while Router enhances cross-chain routing capabilities using CCTP.
Other key integrations include:
- Interport: Offers developer tools and a cross-chain bridge with native CCTP support.
- Mayan Swap: Enables cross-chain swaps via Mayan’s liquidity network.
- WanBridge (by Wanchain): Supports CCTP for secure inter-chain asset transfers.
These tools collectively empower wallets, exchanges, dApps, and financial services to offer seamless USDC mobility across chains—without compromising security or user experience.
Additionally, several leading Sui-native protocols are already live with CCTP routes, including:
- AlphaFiSUI
- Bluefin
- CetusProtocol
- Ensofi
- KriyaDEX
- SuiLendProtocol
- Turbos_Finance
Such widespread adoption signals growing confidence in both the Sui ecosystem and the long-term viability of standardized cross-chain communication.
Powering Real-World Use Cases Across Blockchain Networks
The practical implications of CCTP integration extend far beyond simple token transfers. Developers can now build applications that:
- Onboard users from any supported blockchain without requiring them to swap assets.
- Enable multi-chain payments for e-commerce platforms accepting USDC.
- Facilitate instant withdrawals of USDC to centralized exchanges for trading or off-ramping.
- Support cross-chain yield aggregation and portfolio management tools.
For end users, this means greater flexibility in managing digital assets. Whether you’re trading on a decentralized exchange, lending on a money market protocol, or paying for goods online, you can now use USDC natively across ecosystems—without worrying about wrapped versions or bridge risks.
Moreover, exchanges like Binance have recently announced strategic partnerships with Circle to boost global USDC adoption, further validating the importance of interoperable stablecoin infrastructure.

A Growing Network of Interconnected Blockchains
Today, the CCTP ecosystem supports 72 unique cross-chain routes for USDC, enabling many-to-many transfers across all connected blockchains. This creates a truly interconnected web of liquidity, where value flows freely based on user demand rather than platform silos.
Each new integration strengthens the overall network effect—making it easier for emerging projects to plug into established ecosystems and for users to access services across chains without friction.
As adoption grows, we’re moving closer to a unified digital economy where blockchain interoperability is not an exception but the standard.
Frequently Asked Questions (FAQ)
Q: What is CCTP?
A: The Cross-Chain Transfer Protocol (CCTP), developed by Circle, is a permissionless framework that enables secure, one-to-one transfers of USDC between supported blockchains using a burn-and-mint mechanism.
Q: Which blockchains support CCTP with Sui?
A: Sui supports CCTP-based USDC transfers with Ethereum, Arbitrum, Avalanche, Base, OP Mainnet, Polygon PoS, Solana, and Noble.
Q: Is there a fee for transferring USDC via CCTP?
A: Yes—users pay transaction fees on both the sending and receiving chains. These fees cover gas costs and vary depending on network congestion.
Q: Does CCTP use third-party liquidity?
A: No. CCTP does not require intermediaries or liquidity pools. It uses cryptographic verification to ensure secure transfers without custodial risk.
Q: How does CCTP maintain the USDC peg?
A: When USDC is transferred out of a chain, it is burned. New USDC is minted only upon successful validation on the destination chain, ensuring supply consistency and dollar parity.
Q: Can developers build dApps using CCTP on Sui?
A: Absolutely. Developers can integrate CCTP via Wormhole Connect or use existing SDKs to enable cross-chain features in their applications.
The integration of CCTP into Sui Network represents more than just a technical upgrade—it’s a foundational step toward a truly interoperable blockchain future. By enabling secure, efficient, and trust-minimized movement of USDC, Sui strengthens its role as a hub for innovation in the Move ecosystem and beyond.
As more developers adopt this infrastructure and users demand seamless cross-chain experiences, the value of open, composable financial systems becomes increasingly clear.
