# Get test currencies

Many developers and test users of Web3 applications are faced with a barrier: **the lack of balance in their wallets to test.**

This is because for you to carry out **any transaction on the blockchain, you need to pay fees** for the network to mine (validate) your transaction.&#x20;

{% hint style="warning" %}
Transactions are not just for monetary value, but information recording, information alteration, deletion...
{% endhint %}

To solve this, all blockchain protocols in Test environment (Testnet) provide websites for you to inform your wallet and receive balance to be able to use it.
