 Most contracts are written in Solidity and interpret their data field per [the application binary interface (ABI)](https://docs.soliditylang.org/en/latest/abi-spec.html#formal-specification-of-the-encoding).
 
 However, the ABI was designed for L1, where a byte of calldata costs approximately the same as four arithmetic operations, not L2 where a byte of calldata costs more than a thousand arithmetic operations.

 ## Reducing the cost when you do control the destination contract {#reducing-the-cost-when-you-do-control-the-destination-contract}
 
 If you do have control over the destination contract you can create functions that bypass the `msg.sender` checks because they trust the calldata interpreter.

 ## Conclusion {#conclusion}
 
 Both [Optimism](https://medium.com/ethereum-optimism/the-road-to-sub-dollar-transactions-part-2-compression-edition-6bb2890e3e92) and [Arbitrum](https://developer.offchainlabs.com/docs/special_features) are looking for ways to reduce the size of the calldata written to L1 and therefore the cost of transactions.
