Let’s talk about the three types of access capabilities for RPC nodes.
The most basic is the standard JSON-RPC interface, which handles queries, sending transactions, fetching block data, and other routine operations. This suffices for most scenarios.
The next level is WebSockets connections, which enable real-time monitoring of mempool activity, subscribing to on-chain events, and tracking contract log changes. If you’re building trading bots or monitoring systems, this capability is pretty much essential.
The highest level is trace and debug APIs, mainly for developers who need to deeply analyze transaction execution paths or troubleshoot contract issues. These three tiers correspond to different technical needs—choosing the right one can save you a lot of trouble.
