What is a Base RPC node?

A Base RPC node provides API access to the Base network, enabling applications to interact with this Coinbase-incubated Ethereum Layer 2 for scalable Web3 applications.

How does Base improve Ethereum scalability?

Base keeps full EVM compatibility while offering faster, cheaper transactions as an optimistic rollup on the OP Stack: it executes transactions off-chain and posts their data to Ethereum.

What is GetBlock's Base RPC service?

GetBlock provides managed Base RPC nodes, delivering reliable API endpoints for Base mainnet and Sepolia without requiring personal infrastructure management or maintenance.

What are Flashblocks?

Flashblocks are sub-block preconfirmations Base streams every ~200 ms, ten times faster than its 2-second blocks. On GetBlock they work through standard JSON-RPC and WebSocket endpoints: pending-tag reads reflect preconfirmed transactions, and WebSocket subscriptions stream them as they land.

Which wallets support Base RPC connections?

MetaMask, Coinbase Wallet, and other Ethereum-compatible wallets support Base, either built in or by adding a custom RPC endpoint with chain ID 8453.

How do I connect to Base RPC?

Base RPC connections require the network RPC URL, chain ID 8453, and standard Ethereum JSON-RPC client libraries such as ethers.js, viem or web3.py.

What are common Base RPC methods?

Base supports the standard Ethereum methods, including eth_getBalance, eth_sendRawTransaction, eth_call, eth_getBlockByNumber and eth_estimateGas, plus OP Stack fee fields on transaction receipts.

Does Base RPC support real-time notifications?

Yes. Base RPC provides WebSocket connections for real-time block updates, transaction confirmations, and smart contract event logs.

What is the Base Chain ID?

The Base chain ID is 8453 for mainnet and 84532 for Base Sepolia. Use it when adding Base to a wallet or configuring a client.

Does Base have a block explorer?

Yes. BaseScan and other explorers let you track transactions, view blocks, examine wallet addresses, and monitor smart contracts deployed on Base.

Base is an EVM Layer 2 incubated by Coinbase, which runs its single sequencer. It settles to Ethereum, posts data as blobs and holds a Stage 1 rating from L2BEAT. Blocks land every 2 seconds, while Flashblocks stream preconfirmed state every 200 ms. Base left the Optimism Superchain in March 2026 and moved to multiproofs in May, so each state proposal is backed by a TEE attestation or an SP1 ZK proof. Throughput averages about 125 TPS, and the average fee stays under a cent.

GetBlock serves Base mainnet and Sepolia from Frankfurt, New York and Singapore, with Flashblocks methods on every Shared and Dedicated endpoint at no extra cost. Dedicated Nodes run the Base node or Reth with op-node and add MEV Protection, RPC failover and IP allowlists. Webhooks push wallet and contract events, and wallet risk checks screen counterparties. In October 2026, OpenChainBench ranked GetBlock first among paid Base providers on cold-start latency.
