Introduction
The blockchain ecosystem is inherently multi-chain, with networks like Avalanche, Cosmos, Ethereum, Polygon, and Sui catering to diverse developer needs. While building on a single chain is well-supported, navigating this fragmented landscape requires rethinking application architecture.
Key Collaboration:
- Circle and Axelar are integrating solutions to enable native cross-chain USDC flows via the Cross-Chain Transfer Protocol (CCTP).
- Axelar’s General Message Passing (GMP) extends functionality beyond asset transfers, allowing developers to compose one-click, multi-chain experiences.
Challenges in the Current Cross-Chain Landscape
- Fragmented UX: Users juggle multiple frontends, transactions, and wallets.
- Liquidity Inefficiency: Bridging often requires costly swaps via liquidity providers.
- Security Risks: Bridge hacks have eroded trust in cross-chain solutions.

The Solution: Composable USDC
Cross-Chain Transfer Protocol (CCTP)
- Enables native USDC transfers by burning/minting tokens across chains.
- Eliminates wrapped assets, reducing slippage and fees.
Axelar’s General Message Passing (GMP)
- Transports any payload (not just tokens) for atomic cross-chain actions.
- Example: Swapping ETH for AVAX with USDC as the routing asset—all in one click.
Benefits:
- 1-click transactions (gas paid only on the source chain).
- Enhanced security: Decentralized attestation of burns/mints.
- No slippage: Direct USDC transfers via CCTP.
Use Cases
1. Cross-Chain Swaps
- Swap ETH (Ethereum) for AVAX (Avalanche) via USDC routing—abstracting complexity from users.
2. One-Click Deposits
- Open a dYdX position from Avalanche without wallet switching.
3. Cross-Chain NFTs
- Buy an Ethereum NFT using USDC on Solana, delivered back to Phantom wallet.

FAQ
Q1: How does CCTP improve upon wrapped assets?
A1: By minting/burning USDC natively, it avoids liquidity pool dependencies and reduces risks.
Q2: Is Axelar’s GMP live now?
A2: Yes! Developers can start building with GMP today.
Q3: When will CCTP launch?
A3: Expected on Ethereum and Avalanche mainnets later this year.
Conclusion
This collaboration between Circle and Axelar unlocks composable DeFi, streamlining cross-chain interactions for users and developers. By combining CCTP and GMP, Web3 becomes more accessible, secure, and efficient.
