What Is CCTP (Cross-Chain Transfer Protocol)?

CCTP (Cross-Chain Transfer Protocol) is Circle's system for moving USDC between blockchains. Instead of wrapping the token, it burns native USDC on the source chain and mints native USDC 1:1 on the destination chain.

How does CCTP work?

CCTP avoids the "wrapped token" model that most cross-chain bridges rely on. When you move USDC from one chain to another, the protocol permanently destroys (burns) the USDC on the chain you are leaving, then issues an equal amount of brand-new native USDC on the chain you are arriving at.

Because the destination token is real native USDC rather than a bridged wrapper, it carries no extra peg or custody risk from the bridge itself.

Why does CCTP matter for a global founder?

If you get paid in USDC, your client and your off-ramp may not live on the same chain. CCTP lets that USDC move to wherever it settles cheapest and fastest without converting into a different asset or trusting a third-party bridge. StableCorp supports USDC and USDT payouts across Solana, Ethereum, and Polygon, and Solana settles in roughly 400ms with sub-cent fees, so you can receive on the chain your client prefers and still cash out efficiently.

Where does CCTP fit with StableCorp?

CCTP is the plumbing; StableCorp is the compliant on/off-ramp on top of it. The risky part of stablecoins is rarely the chain itself, it is moving money to and from your bank with a clean paper trail. For Indian founders, StableCorp off-ramps USDC into INR through approved RBI purpose codes, which keeps you on compliant rails rather than the DIY direct-wallet grey area, covered in our guide to FEMA and RBI rules for receiving USDC in India.

Off-ramps for clients incorporated with StableCorp are 0.5%, with direct off-ramp to INR at 1%, versus a market norm of roughly 2.9% headline plus around 2% hidden FX. See pricing for the full breakdown.
