@rawr-multicall/no-side-effect-call

Utility to call contract without side effect of Rawr-multicall.

Please refer to [Rawr-mulitcall] for more details usage.

Contract

The contract only contains a fallback that will call a method of another contract, with the given address and call data. After that it will revert the success status along side with the result.

Input layout for fallback

Fields	Size (bytes)
Gas Limit	4
Address	20
Call data	The rest

• Data is packed tightly together, and won't align to word size.
• If the call does not specify gas limit, the library will automatically set it to $2^{32} - 1$ before sending.
• value is not required, since we can just use msg.value (i.e CALLVALUE instruction).
• call data size is not required either, as we can use CALLDATASIZE instruction.

Output layout for fallback

Or rather the laytout of the revert.

Fields	Size (bytes)
Success	1
Data	The rest

This will be the easiest way to compress the data. The result will be decoded on the client side rather than in the contract.
