PortalCCTP: Cross-Chain USDC in One Flow

Move USDC Now

Launch PortalCCTP

What It Is

PortalCCTP is the Portal Foundation interface for Circle's Cross-Chain Transfer Protocol v2. Pick a source chain, pick a destination, choose how much USDC to send, and PortalCCTP handles the burn, attestation, and mint steps so the same USDC arrives on the other chain.

Vision

Make native USDC feel portable anywhere by wrapping Circle's infrastructure in a simple, confident experience that anyone can run from their own wallet.

Why It Matters

Without PortalCCTP you would juggle contract calls, explorer tabs, and updates from Circle just to move USDC. With PortalCCTP everything happens in one place: you see the right fee, burn on the source chain, watch progress in real time, and mint on the destination as soon as Circle signs off.

How It Works

  1. Select your source chain, destination chain, and amount of USDC.
  2. Connect your wallet; PortalCCTP checks you are on the right network.
  3. Approve USDC if needed, then complete the burn transaction.
  4. The interface watches for the Circle attestation and tells you when it arrives.
  5. Switch to the destination chain and mint the USDC with one more click.
  6. Both transaction links stay on screen so you always have a record.

Fast mode settles in seconds with a suggested fee. Standard mode settles in minutes with no extra cost.
