CCT is a token standard used to send, receive, and compose tokens across chains Chainlink supports. You can learn more about CCT and Superchain interop [here](https://github.com/AstarNetwork/chainlink-ccip-erc7802).

* `SuperchainERC20` is a simple and trust-minimized way for token issuers to make their token available across the Superchain interop cluster.
129-
* Token issuers can use other token standards (xERC20, OFT, NTT) and give `crosschainMint` and `crosschainBurn` permissions to the `SuperchainTokenBridge` or `L2ToL2CrossDomainMessenger` to benefit from Superchain interop.

* Token issuers should include a [ERC-7802](https://eips.ethereum.org/EIPS/eip-7802) interface on their token to simplify downstream integrations.
