Hello guys, does one know how to modify keccak.cairo and/or packed_keccak.cairo to compute a 512bits keccak hash instead of 256 bits?

I'm following a paper that needs 256 bits collision resistance so i need 512 bit keccak. 

There should only a few parameters to change but its quite hard to find them in the Cairo code

How do I create account using starknetjs?

I'm implementing the new version and had a couple Q's:

- Is `useStarknetExecute` now the only transaction method (for multi and single calls).
- Do we update the transaction manager on our end? I seem to remember `useStarknetInvoke` also update this automatically

Hello, I am trying to implement the connect wallet : ``` import { useConnectors } from '-react/core' function YourComponent() { const { connect, connectors } = useConnectors() return ( <div> {connectors.map((connector) => connector.available() ? ( <button key={connector.id()} onClick={() => connect(connector)}> Connect {connector.name()} </button> ) : null )} </div> ) } ``` I feel like connectors will only give the wallet if I have it on my chrome extensions , so whats the point of connector.available() ? I am using : ``` const connectors = getInstalledInjectedConnectors() ```

Hello, I deployed my contract using Argent X.
I click on "Developer settings" and then "Smart contract developement". I declare and deploy the contract.
Also used [this guide](https://www.newton.so/view/63a1890e581919f84b2a4c51) and it helped me.

But the contract is not automatically verified on starkscan or voyager. What should I do to get verified?
