### CCT

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).

* **Security:** Varies depending on the weakest-link among the allowlisted verification mechanisms.
* **Latency:** 1-block latency within the Superchain. Outside the Superchain, latency is variable based on Chainlink's Cross-Chain Interoperability Protocol (CCIP).
* **Cost:** Variable based on allowlisted verification mechanisms.
* **Cross-chain address:** Requires cross-chain registry per deployment.
* **Supported ecosystem:** EVM, Solana


### OFT

OFT is a token standard used to send, receive, and compose tokens across chains LayerZero supports. More information will be added about how OFTs can benefit from Superchain interop at a later date.

## Key takeaways

* `SuperchainERC20` is a simple and trust-minimized way for token issuers to make their token available across the Superchain interop cluster.
* 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.
