The blockchain ecosystem is no longer confined to a single chain. Today, networks like Avalanche, Cosmos, Ethereum, Polygon, and Sui are thriving—each attracting unique developer communities and use cases. While developers have mastered building on individual blockchains, the real challenge lies in navigating this fragmented multi-chain world. Users expect seamless experiences, but current cross-chain solutions often fall short, creating friction, cost, and security concerns.
That’s where composable USDC comes in—a transformative step toward universal Web3 accessibility. Through a powerful collaboration between Circle and Axelar, native USDC will soon flow across chains with full composability, enabled by Circle’s Cross-Chain Transfer Protocol (CCTP) and Axelar’s General Message Passing (GMP). This integration unlocks a future where users interact with decentralized applications (dApps) across chains in a single click—without managing bridges, wrapped tokens, or multiple wallets.

The Problem: Fragmented Cross-Chain User Experience
Today’s cross-chain landscape creates significant barriers to mainstream Web3 adoption. Moving assets between chains typically requires:
- Navigating multiple interfaces (bridge UIs, dApp frontends).
- Submitting several transactions across different networks.
- Managing multiple wallet connections and gas tokens.
From a user’s perspective, USDC on Solana feels like a different asset than USDC on Ethereum—even though they represent the same value. This fragmentation leads to confusion, inefficiency, and increased costs.
Moreover, most cross-chain transfers rely on wrapped assets, which introduce counterparty risks and liquidity dependency. Recent high-profile bridge hacks have further eroded trust in cross-chain security. The result? A disjointed experience that limits user engagement and stifles innovation.
What if developers could build applications that let users move value and execute functions across chains as easily as sending an email?
The Solution: Composable USDC via CCTP and GMP
To solve these challenges, Circle and Axelar are combining two groundbreaking technologies:
1. Cross-Chain Transfer Protocol (CCTP)
Announced at Converge22, CCTP enables native USDC transfers across supported blockchains through a secure burn-and-mint mechanism. Instead of wrapping USDC on destination chains, users send their USDC from one chain, it gets burned, and an equivalent amount is minted on the target chain—directly from Circle’s reserves.
This eliminates wrapped tokens, reduces reliance on liquidity providers, and ensures users always hold genuine USDC.
2. Axelar General Message Passing (GMP)
While most bridges only move assets, Axelar’s GMP can transport any arbitrary data payload—including function calls—to any connected chain. This allows developers to build truly composable cross-chain applications.
When combined with CCTP, GMP enables atomic execution of asset transfers and smart contract interactions. A user initiates one transaction on the source chain; behind the scenes, the system handles cross-chain routing, burning/minting USDC, and executing commands on remote dApps.

Key Benefits of Composable USDC
The fusion of CCTP and GMP delivers tangible improvements for both users and developers:
- True Asset Uniformity: Users always interact with native USDC—no more confusion over token versions or wrappers.
- One-Click Cross-Chain Transactions: Execute complex multi-chain operations with a single transaction. Pay gas only on the source chain.
- No Slippage or Liquidity Risks: Since transfers occur natively via burn-and-mint, there's no need for AMM pools or liquidity providers.
- Enhanced Security: Axelar’s decentralized network verifies the burning of USDC on the source chain before any action is taken on the destination chain—adding an extra layer of trust.
- Developer Empowerment: With the Axelar SDK, teams can monitor, debug, and relay cross-chain transactions seamlessly. All activity is visible via axelarscan.io and its API.
Real-World Use Cases
1. Seamless Cross-Chain Swaps
Imagine swapping ETH on Ethereum for AVAX on Avalanche in one click. The process works like this:
- ETH is swapped for USDC on Ethereum.
- USDC is natively transferred to Avalanche via CCTP.
- On Avalanche, USDC is swapped for AVAX—all triggered by a single user transaction.
Liquidity providers never hold bridged assets—they maintain native positions on each chain—eliminating bridge-related risk.
2. One-Click Deposits to App-Specific Chains
dYdX operates on its own application-specific chain. Currently, depositing funds requires switching networks and managing gas on a new chain.
With composable USDC:
- A user on Avalanche sends a single transaction.
- USDC is transferred natively to the dYdX chain.
- A position is automatically opened—all without the user knowing they interacted with a different network.
Closing the position works the same way—initiated from Avalanche, executed remotely.
3. Cross-Chain NFT Purchases
A user holding USDC in their Phantom wallet on Solana wants to buy an NFT listed on OpenSea (Ethereum). Today, this requires:
- Transferring funds to Ethereum.
- Using MetaMask.
- Paying ETH for gas.
- Bridging the NFT back to Solana.
With GMP + CCTP:
- The user initiates one transaction from Phantom.
- USDC moves natively to Ethereum.
- The NFT is purchased and bridged back to Solana.
- The entire experience happens within the Solana wallet interface.
No wallet switching. No wrapped tokens. Just seamless execution.
Frequently Asked Questions (FAQ)
Q: What is composable USDC?
A: Composable USDC refers to the ability to use native USDC across multiple blockchains in combination with general-purpose messages (like function calls), enabling complex, multi-step cross-chain operations from a single user action.
Q: How does CCTP differ from traditional bridges?
A: Unlike bridges that create wrapped tokens, CCTP uses a burn-and-mint model directly backed by Circle. This means users always hold real USDC—no third-party custody or liquidity pools involved.
Q: Is this solution secure?
A: Yes. CCTP inherits Circle’s robust security model, while Axelar adds decentralized validation of cross-chain events. Together, they reduce attack surfaces compared to traditional bridge architectures.
Q: Which chains are supported?
A: Initial support includes Ethereum and Avalanche, with plans to expand to other EVM and non-EVM chains as CCTP rolls out.
Q: Do users need to pay gas on multiple chains?
A: No. With Axelar’s gas services, users pay gas only on the source chain. Axelar handles relaying and execution fees on destination chains.
Q: Can developers start building now?
A: Absolutely. Axelar’s GMP is live today. Developers can explore documentation and examples at docs.axelar.dev.
The Future of Chain-Abstracted Finance
Composable USDC represents a pivotal shift toward chain abstraction—where users no longer need to understand or manage underlying blockchain infrastructure. Applications handle complexity behind the scenes, delivering intuitive, one-click experiences.
As Circle’s CCTP launches on mainnet and integrates with Axelar’s network, we’re entering a new era of interoperability. Developers gain unprecedented flexibility to design global financial systems that span ecosystems. Users benefit from faster, cheaper, and safer interactions across Web3.
The vision is clear: make blockchain technology invisible so its value becomes universal.
