Subscribing to all transactions of a Token

This example illustrates subscribing to all transactions of a token on Raydium

So far we were streaming all transaction of a Solana address. Now imagine, if you want all transactions of a token, but only on Raydium V4. You don't want transactions of that token on Orca or any other dex. In this case we will use a new field accountRequired.

{
  "slots": {
    "slots": {}
  },
  "accounts": {},
  "transactions": {
    "raydiumPoolv4": {
      "vote": false,
      "failed": false,
      "accountInclude": [
        "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
      ],
      "accountRequired": ["675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8"]
    }
  },
  "blocks": {},
  "blocksMeta": {},
  "accountsDataSlice": [],
  "commitment": CommitmentLevel.CONFIRMED
}

This lets you add another layer of filter, now gRPC will stream you transactions of that token only if it has Raydium V4 address in it.
