## Specification
### Overview
The following specification revolves around the structure and description of a cross-chain storage router tasked with the responsibility of writing to an L2 or database storage. This document introduces `StorageRoutedToL2()` and `StorageRoutedToDatabase()` storage routers, and proposes that new `StorageRoutedTo__()` reverts be allowed through new EIPs that sufficiently detail their interfaces and designs. Some foreseen examples of new storage routers include `StorageRoutedToSolana()` for Solana, `StorageRoutedToFilecoin()` for Filecoin, `StorageRoutedToIPFS()` for IPFS, `StorageRoutedToIPNS()` for IPNS, `StorageRoutedToArweave()` for Arweave, `StorageRoutedToArNS()` for ArNS, `StorageRoutedToSwarm()` for Swarm etc.

### L1 Router: `StorageRoutedToL1()`
A minimal L1 router only requires the `contractL1` address to which routing must be made, while the clients must ensure that the calldata is invariant under routing to another contract. One example implementation of an L1 router is given below.
