Base Vibenet RPC and Chain Settings: How Do You Connect?
Base Vibenet is a Base-based network that developers reference when they need RPC endpoints and chain settings for wallet or app configuration. This page explains how to identify t...
What is the Base chain ID, and where can you get a free Base RPC endpoint?
Base mainnet uses chain ID 8453, and Base Sepolia uses chain ID 84532. You need the correct chain ID plus an RPC URL whenever you add Base to a wallet or point a client at the netw...
What is a public Base RPC URL and when should you use one?
A public Base RPC URL is a shared, no-signup HTTP endpoint that lets your app read Base chain data and broadcast transactions. It is the fastest way to connect a wallet, script, or...
Base RPC Example: Endpoint Settings, curl Calls, and Debugging
This page shows concrete Base RPC examples you can copy: the public endpoint, chain settings for wallets, curl JSON-RPC calls, and a JavaScript snippet using viem. It also covers h...
Base public RPC endpoints and independent performance metrics: what should you evaluate?
Base public RPC endpoints are convenient for prototyping and light reads, but they are shared infrastructure with no guarantees on throughput, rate limits, or availability. Indepen...
Base RPC API: Endpoint Settings, Marketplace Alternatives, and Production Setup
Base RPC is the JSON-RPC interface to the Base L2 network, used to read state, send transactions, and subscribe to events. This page covers the public endpoint, chain settings, and...
What is the Base public RPC URL and which dev tools should you use with it?
The Base public RPC URL is a shared, no-key HTTP endpoint that lets you read chain data and send transactions to Base mainnet. OnFinality publishes a public endpoint at https://bas...
Base Sepolia public RPC endpoint: chain settings, faucet, and debugging
Base Sepolia is the testnet for Base, an OP Stack L2 that settles to Ethereum Sepolia. To connect, point your wallet or app at a Base Sepolia RPC endpoint and set chain ID 84532, c...
Base Node RPC: Endpoint Settings, Chain IDs, and Debugging
Base is an Ethereum L2 built on the OP Stack, so its RPC surface looks familiar to any Ethereum developer: JSON-RPC over HTTP, the same eth_* methods, and chain ID 8453 for mainnet...
Base L2 on Ethereum: How to Connect and When to Use It
Base is an Ethereum Layer 2 network that settles transactions on Ethereum while executing them on its own chain. Developers interact with it through an EVM-compatible JSON-RPC endp...
What is a Base NFT API and how do you query NFT data on Base?
A Base NFT API is the set of RPC methods and indexed data services you use to read NFT ownership, metadata, and transfer history on the Base network. Standard JSON-RPC calls like e...
What is Base Sepolia and when should you use it?
Base Sepolia is the testnet for Base, an Ethereum Layer 2 built on the OP Stack. It mirrors Base mainnet's EVM behaviour with chain ID 84532 and test ETH, so you can deploy contrac...
