Is starknet.id legit?

I'm trying to use Nile (StarkNet).
I send this function call : 

```cairo
func setBaseURI{pedersen_ptr: HashBuiltin*, syscall_ptr: felt*, range_check_ptr}(
    baseUri_len: felt, baseUri: felt*
)
```

The only thing that would get processed is 

```
nile send account mycontract setBaseURI 3 1 1 1
```

but I don't think that's the right way. How do you pass an array of felt to call with Nile?

Does AA support "Session Keys" so I can avoid signing too many transactions when they are redundant?

Are there situations in which we prefer declaring variables as `local` vs `tempvar`?
I understand that both are used to avoid variables being revoked, curious to know if they are different in any way

The following code:



```
func pow4(n) -> (m : felt):
    alloc_locals
    local x

    jmp body if n != 0
    [ap] = 0; ap++
    ret

    body:
    x = n * n
    [ap] = x * x; ap++
    ret
end

func main():
    pow4(n=5)
    ret
end

```

is declared inefficient in the [doc](https://starknet.io/docs/how_cairo_works/consts.html#id7) because of non-continuous memory.


I ran it and could not see any hole in the memory table:



```
Addr  Value
-----------
â‹®
###
â‹®
1:0   2:0
1:1   3:0
1:2   5
1:3   1:2
1:4   0:21
1:5   25
1:6   625

```

so I don't understand where the problem is. I do see a hole with `n=0` though:



```
Addr  Value
-----------
â‹®
###
â‹®
1:0   2:0
1:1   3:0
1:2   0
1:3   1:2
1:4   0:21
â‹®
1:6   0

```

that I can fix using:



```
    jmp body if n != 0
    x = 0
    ret

```

but it's not what's suggested:


* Move the instruction alloc\_locals.
* or Use tempvar instead of local.

How can I get ETH for the test net in StarkNet?

Hi, I'm trying to solve a Playground exercise on the [Cairo website](https://www.cairo-lang.org/playground/) named "Conditionals". I don't know how to make OR operator in Cairo. I tried something like that:

```
func abs_eq(x: felt, y: felt) -> (bit: felt) {
    if (x == -y) or (x == y) {
        return (bit=1);
    } else {
        return (bit=0);
    }
}
```

but it gives me an error


`Error: code:12:18: Unexpected token Token('IDENTIFIER', 'or'). Expected: "{".
    if (x == -y) or (x == y) {`

How can I solve it?
