# All Transactions of a Token

So far we were streaming all transaction of a Solana address. Now imagine, if you want all transactions of a token, but only on <mark style="color:yellow;">Raydium V4.</mark> You don't want transactions of that token on Orca or any other dex. In this case we will use a new field <mark style="color:yellow;">**accountRequired.**</mark>

You can copy and paste this code on Replit to see it action, or simply remix [<mark style="color:yellow;">this code</mark>](https://replit.com/@shyft-to/streaming-transactions-for-tokens-related-to-address?v=1) on Replit.
{% endhint %}

This  lets you add another layer of filter, now gRPC will stream you transactions of that token only if it has <mark style="color:yellow;">Raydium V4</mark> address in it.
