What is the technical difference between Solidity -> Cairo transpiler and ZK-EVM Kakarot for StarkNet? Both of them interpret Solidity into Cairo and it can help Solidity developers to use StarkNet. 

But really, how does [Kakarot](https://github.com/sayajin-labs/kakarot) compare to [Nethermind's Warp](https://github.com/NethermindEth/warp)?

Hey! With starknetjs(4.15.1) I am trying to declare a contract on devnet(0.4.2) using one of  predeployed accounts:

```
const account = new Account(
  provider,    '0x33507ff2edf12c12c73d0b6d1d90de9fac12a355de1097ab305249612451919',
  ec.getKeyPair('0x1de9ea6670d3da1fc735df5ef7697fb9')
);
...
const response = await account.declare({contract, classHash})
```

In return I get:

```
