);About Linea
Connect your dApp, bot, or protocol to Linea Mainnet with BoltRPC. For MetaMask-connected dApps and ConsenSys ecosystem protocols, reliable Linea RPC is the infrastructure layer that keeps user-facing applications responsive.

Linea is ConsenSys’s ZK rollup, backed by the same company that built MetaMask and Infura. Its deep MetaMask integration means Linea has native wallet support for all MetaMask users out of the box, giving it immediate distribution to one of the largest wallet audiences in Web3. Linea’s developer grants program and institutional backing attract production-grade teams. The chain’s growing DeFi TVL is driven by protocols that benefit from ConsenSys’s developer network. Teams already using Infura or MetaMask infrastructure often migrate to Linea as a natural extension of their existing stack.
Linea’s MetaMask integration creates a distinct traffic signature compared to other zkEVM chains. A large portion of Linea users arrive through the MetaMask mobile and extension wallet, where wallet UX operations generate dense short-burst RPC traffic: balance reads, pending transaction checks, gas estimation and token approval status queries all fire in rapid succession when a user opens their wallet or initiates a transaction. This consumer wallet traffic pattern is read-heavy and bursty, peaking at moments of user activity rather than running at a flat background rate.
For DeFi protocols deployed on Linea, the dominant RPC workload is eth_call for price and position reads combined with eth_getLogs for event tracking. Protocols migrating from Ethereum mainnet to Linea often retain their existing event monitoring architecture, which means transferring the same log-scanning logic to Linea. The ZK proof batching cadence on Linea means that while sequencer confirmations are fast, log indexers that track ZK proof submissions to Ethereum will see batch events at a lower frequency than standard block events. Both workloads need to be handled efficiently in production.
Linea’s 2-second blocks are fast enough that polling-based architectures accumulate significant request volume over time. A service polling every block for a single monitored address generates 43,200 calls per day from block number checks alone. WebSocket subscriptions to contract events are the most efficient architecture for Linea applications that need real-time state.
Why BoltRPC
Linea's native MetaMask support means it sees traffic patterns from consumer wallets alongside DeFi protocols. Volume spikes during market events and new feature launches are common. For teams building dApps that MetaMask users land on, RPC reliability is directly visible to end users. A failed or slow request means a broken transaction for a real user.
Linea connects to the broader ConsenSys developer ecosystem. Protocols migrating from or integrating with MetaMask, Truffle, or Infura infrastructure land on Linea naturally. These are often production-grade teams with volume requirements that public endpoints cannot serve.
As Linea's ecosystem grows, your RPC usage will grow with it. Fixed monthly plans priced in request units mean your costs scale predictably as you add more users, more chains, or more features.
Any Ethereum code works on Linea with a single endpoint change. The same Solidity contracts, ABIs, and tooling all apply.
Subscribe to new blocks and contract events via WebSocket. Particularly useful for wallet apps that need to update balance displays in real time.
BoltRPC supports Linea alongside Scroll and zkSync Era. If you are evaluating or deploying across multiple zkEVM chains, one API key covers all three.
