GHOCC is a GHO Facilitator that is pegged to USDC on Mainnet (Sepolia for the demo), and that also functions as a cross-chain facilitator using Chainlink CCIP.
The following capabilities are available in the GHOCC smart contracts:
- paying USDC and receiving an equivalent amount of GHO in return
- redeeming the GHO for USDC
- transferring the GHO cross-chain using Chainlink CCIP
- transferring the GHO back to the source chain (Mainnet or Sepolia)
A fee is charged for swapping USDC for GHO, and for sending GHO cross-chain. The fees are distributable only to the Aave Treasury.
Since only pre-deployed token pools are available at the moment for CCIP on testnets, GHOCC uses a simple message send, with the details of the transfer. It verifies that it came from the approved Facilitator on Sepolia, and if it did, it mints wrapped GHO on Polygon Mumbai.
It is only deployed between Sepolia and Polygon Mumbai for the demo, but if there is demand it could be deployed to any other chain.
