RPC (Remote Procedure Call)
A connection endpoint that lets your wallet or dApp communicate directly with a blockchain node.
An RPC (Remote Procedure Call) is like a bridge
between your crypto wallet and the blockchain.
It allows your wallet or dApp to send and receive data —
for example, to check balances, submit transactions,
or read smart contract information.
Each blockchain has its own RPC URLs,
usually provided by nodes (like Infura, Alchemy, or your own).
Why it matters
- Without an RPC connection, your wallet can’t talk to the blockchain
- Custom RPCs allow you to connect to different networks (like testnets or L2s)
- A bad or fake RPC can steal your transaction data or redirect funds
Using a verified RPC ensures your wallet is communicating securely
with the correct blockchain network.
💡 Lanzo Tip
Only use official or trusted RPC endpoints —
if someone sends you a random one, it’s probably a trap ⚠️
