It's not working for me

If the function with the useCallback is not passed to a child I don't see the point, as this has a computational cost and I would prefer to give it to a useMemo in useContractItems and run the simple logic in the effects.

Such as:

const userContractItems = useMemo(() => {
    return Array.isArray(items) ? items.filter(item => item.hidden === false) : [];
  }, [items]);

  useEffect(() => {
    const updatedChain = getChain(networkConnected);
    setChain(updatedChain);
  }, [networkConnected]);

  useMultiEventListener([WalletConnectionEvents.customChainNameChanged], () => {
    const updatedChain = getChain(networkConnected);
    setChain(updatedChain);
  });
