Application developers must complete two steps to make their tokens compatible with `SuperchainERC20`.
Setting this up in advance ensures tokens will benefit from interop when it becomes available.

* Grant permission to `SuperchainTokenBridge` (address `0x4200000000000000000000000000000000000028`) to call `crosschainMint` and `crosschainBurn`.
* Your contract must implement `crosschainMint` and `crosschainBurn`, and include a check that the `SuperchainTokenBridge` (address `0x4200000000000000000000000000000000000028`) can call them. No additional permissioning or role setup is required.

Outdated
If you are using [`SuperchainERC20`](https://github.com/ethereum-optimism/optimism/blob/develop/packages/contracts-bedrock/src/L2/SuperchainERC20.sol) this is already done for you.
