IndirectCall library

[Amxx]

Some contract are required to perform arbitrary action controlled by user input. This is dangerous if the contract has special permissions, or holds assets. In such cases, using a relay contract can be useful to change the msg.sender of the outgoing call. This pattern is used in the ERC-4337 entrypoint that relies on a helper called the "senderCreator" when calling account factories. Similarly ERC-6942 does factory calls that could be dangerous if performed directly.

This contract provides a indirectCall that can be used to perform dangerous calls. These calls are indirect through a minimal relayer.

Edit: this can also be usefull for some construction that use a singleton with "satellites" contract that hold assets/permissions.
