How to use different blockchain networks?

Blockchain networks are digital ledgers that store data in blocks linked in a chain. Each blockchain operates independently with its own set of rules and features. Examples include Bitcoin, Ethereum, and Binance Smart Chain. These networks support various applications, from simple transactions to complex smart contracts.

Interacting with Different Networks

Adding Networks

To interact with different networks, your wallet must be compatible with them. Some wallets allow you to add networks manually.

Switching Networks

In multi-currency wallets, you can switch between networks, usually via a dropdown menu. This changes the environment in which your transactions occur.

Importance of RPCs in Blockchain Interaction

Definition of RPC

Remote Procedure Call (RPC) is a protocol that one program can use to request a service from a program located on another computer in a network.

Role in Blockchains

RPCs are crucial for blockchain interactions. They are used to:

  • Send transactions.

  • Query network data.

  • Retrieve user balances.

  • Call smart contract functions.

Blockchain Nodes and RPC URLs

  • Each blockchain network has nodes, computers connected to the network, maintaining its ledger.

  • To interact with a blockchain, your wallet communicates with these nodes.

  • This communication often occurs through RPC URLs, which are endpoints allowing your wallet to connect to a node on the blockchain.

Custom RPCs

For some networks, especially smaller or private ones, you might need to configure custom RPC settings in your wallet to connect.

Secure Interaction Tips

  1. Use Reputable Wallets: Choose wallets with a strong security record.

  2. Keep Software Updated: Regular updates offer protection against vulnerabilities.

  3. Beware of Phishing: Be cautious about links or requests for your keys.

  4. Secure Your Keys: Never share your private keys or seed phrases.


Interacting with different blockchain networks through a wallet involves understanding the types of wallets, adding and switching networks, and the crucial role of RPCs in facilitating these interactions. Always prioritize security in all blockchain activities.
