question about miner's config using xmr-node-proxy

[MrCook1es]

I'm using XMRIG with xmr-node-proxy and everything works properly.
But one thing is not clear to me, which of the 2 miner's config is correct? (both apparently seem to work properly)

XMRIG config1.json

"pools": [
        {
            "url": "xmr-node-proxy-IP:3333",
            "user": "4xxx.....WALLET-ADDRESS",
            "pass": "MINER-NAME",
            "use-tls": false,
            "keepalive": true,
            "nicehash": true

XMRIG config2.json

"pools": [
        {
            "url": "xmr-node-proxy-IP:3333",
            "user": "MINER-NAME",
            "pass": "x",
            "use-tls": false,
            "keepalive": true,
            "nicehash": true

.
For the correct management of shares with xmr-node-proxy, it is mandatory to insert the wallet address in the config.json of the miner?

Not mandatory. Wallet address can be empty or whatever.

I had read a message from Snipa that indicated the wallet address of the miner as a sort of authentication for the shares, but maybe I misunderstood.

@Snipa22 Snipa what do you think? Could you confirm too?

Thanks!
