# /walletsolidity/gettransactioncountbyblocknum - Tron

This endpoint returns the number of transactions in a confirmed block, identified by height.

{% hint style="info" %}
This is a Solidity-node endpoint. It returns only confirmed, irreversible data, so it is the correct interface for balance and payment verification. The Fullnode serves the same operation at `https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/wallet/gettransactioncountbyblocknum` over the latest, possibly unconfirmed state.
{% endhint %}

## Parameters

| Parameter | Type    | Required | Description      |
| --------- | ------- | -------- | ---------------- |
