Which lib can help me to make a multicall in JS for StarkNet?

Hi! I like writing my Cairo code in vim. However, I don't like that Cairo lang code has no auto-format and syntax highlighting (see screenshot):

I'm looking for a plugin to write Cairo contracts on Starknet in vim with all pretty formatting. Can you recommend any and how to install it as well?



Does anyone know a vim plugin for StarkNet smart contracts?

Say I am calling the following function test. Why can I call with either of these function signatures and get the same result?


`func test{syscall_ptr : felt*}():`


or


`func test{syscall_ptr : felt*, range_check_ptr}():`

Cairo: are builtins always needed to be expressed in function signature?

Hey!
I had a question about what would be the cleanest way to imitate a `uint32` or `uint64` in cairo. Two approaches came to mind:
1. Simply use a felt and check that is less than `2**32 - 1`
2. Pass a Uint256 and check that var.high == 0 and var.low is less than `2 ** 32 -1`

First approach seems straightforward, but I wanted to know if there was a convention for this or a better way.

How to check for smaller Uints in Cairo?

hi, i used the starkgate bridge from stark to eth one hour ago. Withdrawal has not occurred yet. How many hours does the process take? My tx hash is: <address>cfa0c02d013658804505506

How many time does it take for stark to eth starkgate bridge process?

gm all! I am working on this project https://github.com/outsider-analytics/ZK-Circuit-Performance-and-Security-Data on a grant from the EF PSE team.  I need to understand what hash types are being used in the STARK proof creations.  I have poured through the docs and can't seem to find it.  I have seen reference to Pedersen and Rescue, but can't find anything definitive.  Can someone point me towards any documentation that can help me?

Can anyone point me to Pedersen, Rescue references? StarkNet / Cairo Lang

I'm new to Cairo and I want to know what is the difference when I write `let x = 1;` and `tempvar x = 1;`. Is there any difference in Cairo Lang between let and tempvar?

Cairo: let vs tempvar what is the difference?

Hey there, is there an existing Math64x61_pow implementation to compute power of a floating point elevated to an integer power?

edit: looks like there is 🙂
