3rd party interop solutions for L2s often wait for Ethereum finalization (15min+) when transferring tokens from an L2 to mitigate the double spend problem. However, that solution results in high latency and poor user experience. Superchain interop is [reorg aware](./reorg) - this means users can transfer assets across chains in the Superchain with 1-block latency, and should a reorg happen, either both the source and destination transactions would remain, or both of them would revert. In every case, there is no window of opportunity to double spend. Low latency interop that mitigates the double spend problem is now possible with Superchain interop.
