What is the current behavior?

Resolves #1464

What is the new behavior?

• Implements the MulticallCairo precompile - at address 0x75003, that receives an flattened array of cairo calls and executes them sequentially.
• Permisionless precompile: anyone can call it, unlike 0x75001
• ⚠️ For security purposes this precompile CANNOT be called with DELEGATECALL or CALLCODE ⚠️
• Ignores return data of the Cairo calls
  • Highlights the requirement of a SinglecallCairo precompile that would be permissionless, and also have delegatecall deactivated ?

transform to Uint256 and compare to Prime to ensure this does not overflow ?

[enitrat]

bytes32_to_uint256 -> ensure not > PRIME -> reconstruct felt from (low, high)?

idk if we should put guard rails around this. @ClementWalter thoughts?

maybe add a comment about the fact that because of gas cost, input_len < 2**128

[ClementWalter]

it's better to use our wrapper call and invoke as starknet py is not so stable, and so it's easier when we need to update/patch

[enitrat]

call and invoke are good for contracts available in artifacts, not so much when passing an address because the calldata is not parsed.
