What is RPC Network?

What Is an RPC Network?

An RPC (Remote Procedure Call) network serves as a communication channel that allows your wallet to interact directly with blockchain nodes. By leveraging the RPC programming paradigm, applications can request nodes to execute queries or broadcast transactions—essentially instructing the network to act on your behalf.

Think of RPC as asking a skilled librarian to fetch information or carry out specific tasks for you. Blockchain nodes operate like libraries, storing ledger data and smart contract states. Your wallet or DApp sends requests, and the node responds with data or broadcasts your transactions according to the network’s consensus rules.

Why Is the RPC Network Essential in Blockchain?

The RPC network is fundamental because nearly all on-chain activities rely on it—including checking balances, querying transaction history, interacting with smart contracts, and submitting transactions. Without an RPC network, your wallet cannot track your asset status or transmit transactions across the blockchain.

Practically, when you open a wallet on any blockchain, it loads that chain’s RPC network address. For example, when depositing assets on an exchange like Gate, the platform relies on its own or managed RPC nodes to confirm transaction status, enabling account crediting and risk management workflows.

How Does an RPC Network Work?

The RPC network operates on a request-response model. Your wallet sends a request specifying the desired action (method name) and relevant parameters; the node processes this and returns a result.

A common communication protocol is JSON-RPC, which uses JSON formatting for standardized messaging between different software systems. Requests are typically transmitted via HTTP (for single calls) or WebSocket (for persistent connections and event subscriptions). For example, to check account balances, wallets might invoke methods like “eth_getBalance”; to submit transactions, they use “eth_sendRawTransaction,” transmitting signed transaction data for node propagation.

What Can You Do With an RPC Network? Common Use Cases

RPC networks support three main functions: reading blockchain data, executing smart contract interactions, and submitting or tracking transactions. Wallets use RPC to load balances and token lists at startup; DApps retrieve contract states and event logs upon page load; after sending a transaction, users track hashes, confirmations, and final status through RPC calls.

Typical scenarios include:

• Viewing attributes and ownership of an NFT in your wallet—RPC requests fetch contract state and event records from nodes.
• During decentralized exchange operations, DApps read prices and estimate gas fees via RPC, then broadcast signed transactions.
• On exchanges like Gate, deposit confirmation workflows use RPC to query block confirmations and transaction logs to validate credits and assess risk.

How Do You Use an RPC Network? Steps to Add an RPC Network in Your Wallet

Using an RPC network typically involves adding or switching networks in your wallet. To connect to a new chain, follow these steps:

Step 1: Gather necessary details—network name, RPC URL, chain ID, token symbol, and block explorer address. These parameters are usually found in project documentation or official sites.

Step 2: Open your wallet’s network settings. Locate the “Add Network” or “Custom RPC Network” option.

Step 3: Paste the RPC URL and chain ID. Ensure these come from trusted sources to avoid malicious endpoints.

Step 4: Save and switch to the selected RPC network. Return to your wallet homepage to verify balances, tokens, and transaction functionality.

How to Choose an RPC Network? Evaluating Performance and Stability

Selecting an RPC network involves assessing availability, latency, throughput, reliability, and geographic coverage. High availability means minimal downtime; low latency enhances user experience; throughput determines concurrent request capacity; reliability covers failover capabilities; geographic coverage affects global access speed.

Evaluation methods include:

• User experience: Is page loading smooth? Do event subscriptions remain stable? Are transactions broadcasted and confirmed promptly?
• Technical metrics: Monitor response times, error rates, and rate limits. For high-traffic DApps, prepare primary and backup RPC networks with automatic failover.

In multi-chain environments, prefer RPC networks provided by official project teams or reputable third-party services. Monitor service status pages and announcements. Exchanges like Gate often use self-hosted or managed nodes to guarantee stability for critical processes.

What Are the Risks of Using RPC Networks? Key Considerations

RPC network risks revolve around trustworthiness and availability. Using unverified RPC URLs can lead to tampered data or blocked transaction submissions. Centralized providers may suffer outages or impose censorship, disrupting your interactions.

Best practices:

• Verify sources: Only use RPC URLs from official documentation or reputable channels.
• Mind privacy: RPC requests reveal your address and usage patterns—choose services with clear privacy policies.
• Prepare for disaster recovery: Set up backup RPC networks and retry mechanisms for essential applications to mitigate single points of failure.
• For financial transactions: Test with small amounts before scaling up; monitor gas fees, network congestion, and manage failed transaction retries appropriately.

How Is an RPC Network Different From an API?

RPC networks focus on “remote method invocation,” enabling direct function calls on target systems. APIs are broader interfaces—these can be implemented using RPC style, RESTful protocols, or other formats. JSON-RPC in blockchain is a type of API that closely aligns with invoking specific methods with parameters.

Thus, RPC networks are tightly integrated with blockchain nodes—their method names and return values map closely to protocol-level functions. Traditional APIs often provide higher-level abstractions or aggregated features suited for business logic.

What’s Next for RPC Networks in the Multi-Chain Era?

As of late 2024, leading wallets commonly support custom RPC URLs. Multi-chain DApps integrate multiple providers with health checks and automated switching. As account abstraction and complex contract interactions grow more common, demand for WebSocket subscriptions and event indexing is rising—driving investment in real-time performance and availability for RPC networks.

Future trends include smarter routing and disaster recovery, improved privacy and censorship resistance (such as self-hosted nodes and decentralized RPC solutions), and standardization of cross-chain unified interfaces—all aimed at enhancing development and user experience.

Summary: Key Takeaways About RPC Networks

An RPC network is the essential communication bridge between wallets and blockchain nodes—handling both data queries and transaction submissions. Understanding its request-response mechanism, mastering how to add or switch networks in your wallet, and selecting services based on availability, latency, and reliability will dramatically improve the stability and security of your DApp or wallet experience. For financial operations, always verify sources, set up backup nodes, test with small amounts first, and avoid risks associated with single points of failure or untrusted services.

FAQ

Why Can’t I Transact After Connecting My Wallet to an RPC Network?

This is usually caused by offline nodes, network congestion, or configuration errors. First check node status; try switching to another provider (such as Gate’s public node); ensure your network ID and chain ID are correct. If issues persist, clear your browser cache before reconnecting.

What’s the Real Difference Between Free and Paid RPC Services?

Free RPCs generally impose rate limits and may be less reliable—suitable for light usage only. Paid RPCs offer higher request limits, faster response times, and priority support. For frequent transactions or development needs, paid options can significantly reduce timeout failures. Platforms like Gate also provide robust RPC services for users.

Does It Matter if My RPC URL Uses “http” vs “https”?

https is encrypted for greater security—always preferred. http may be slightly faster but transmits unencrypted data. For public access the difference is minor; for sensitive operations always use https. Most modern wallets and exchanges default to https endpoints.

Why Do Different RPC Nodes on the Same Chain Show Different Account Balances?

This typically results from node synchronization delays or inconsistent states. Blockchain nodes need time to update with the latest blocks; sync progress can vary across providers. Switch to fully synced nodes or wait for several block confirmations before checking balances. Using mature platforms like Gate can minimize this risk.

Can I Run My Own RPC Node? What Are the Requirements?

Yes—you’ll need a high-performance server, sufficient bandwidth, plus expertise in maintenance and security. It’s costly and performance issues are common; most users opt for public RPCs for convenience. For development needs, try platforms like Gate first before considering self-hosting solutions.
