Cross-Chain Transfer Protocol (CCTP)

Natively interoperable USDC via CCTP

The Cross-Chain Transfer Protocol (CCTP), developed by Circle, enables the transfer of USDC across blockchains. It achieves this by burning USDC on the source chain and minting an equivalent amount on the destination chain.

CCTP does not rely on pooled USDC liquidity for cross-chain transfers, thereby enhancing capital efficiency and eliminating fees by liquidity providers. This also avoids unofficial, bridged versions of USDC.

Before CCTP, USDC liquidity was fragmented due to the need for third-party bridged versions of USDC.

Borrowing via Cross-Chain Transfer Protocol (CCTP)

Circle’s CCTP unifies USDC liquidity across Pike's Hub and Spoke chains. For example, when a user wants to borrow USDC on Optimism but there is insufficient liquidity available, Pike steps in to transfer USDC from other chains such as from Arbitrum to Optimism.

In the example above, the burning of USDC emits an event on the source chain (Arbitrum), which is automatically observed by Circle’s attestation service. Pike would then fetch the signed attestation from Circle, which then enables the minting of USDC on the destination chain (Optimism).

USDC Token Addresses

USDC is available natively on Pike's supported networks. When withdrawing USDCs, you may need to manually add the USDC token address to your wallet as follows:

Network	USDC Token Address
Ethereum	0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48
Base	0x833589fcd6edb6e08f4c7c32d4f71b54bda02913
Optimism	0x0b2c639c533813f4aa9d7837caf62653d097ff85
Arbitrum	0xaf88d065e77c8cc2239327c5edb3a432268e5831
