#### What are RPC URL? <a href="#what-are-rpc-url" id="what-are-rpc-url"></a>

The basic RPC addresses offered by blockchain networks are not designed for very large queries, especially considering that many users send requests there at the same time, this means a serious load for the servers. Therefore, you need to get these services from services that provide special RPC address services for Blockchain networks. Otherwise, you may face RPC blocking issues in your Blockchain payments process.
