What is the Linea RPC URL?

The Linea Mainnet RPC URL with BoltRPC is https://eu.endpoints.matrixed.link/rpc/linea?auth=YOUR_API_KEY. Replace YOUR_API_KEY with your API key from trial.boltrpc.io. The chain ID is 59144.

How do I add Linea to MetaMask?

Linea can be added directly inside MetaMask via the network selector. To use BoltRPC as your Linea RPC, go to Settings, then Networks, then Linea, then Edit, and replace the RPC URL with https://eu.endpoints.matrixed.link/rpc/linea?auth=YOUR_API_KEY.

Linea is built by ConsenSys, the company behind MetaMask, Infura, and Truffle. It is a zkEVM L2 settling to Ethereum with zero-knowledge proofs, with native MetaMask wallet support.

A zkEVM is an EVM-compatible blockchain that uses zero-knowledge proofs to verify transaction validity. Unlike Optimistic Rollups, zkEVMs do not require a challenge period - proofs are cryptographically verifiable immediately.

What is the difference between Linea and other zkEVMs?

Linea is ConsenSys' zkEVM. Scroll focuses on bytecode-level EVM equivalence. zkSync Era focuses on native account abstraction. All are zkEVMs settling to Ethereum with different approaches to proof generation.

Does BoltRPC support WebSocket for Linea?

Yes. BoltRPC provides WebSocket endpoints for Linea at wss://eu.endpoints.matrixed.link/ws/linea?auth=YOUR_API_KEY. Use WebSocket for real-time event subscriptions: new blocks, pending transactions, contract events.

How does Linea finality work?

Linea uses ZK proof batches submitted to Ethereum for verification. Once verified, transactions achieve finality in approximately 1 to 2 hours. Before proof finality, sequencer confirmation is reliable for most application purposes.

Why BoltRPC

Built for teams that ship on Linea.

Reliable infrastructure for MetaMask-connected dApps

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.

ConsenSys ecosystem protocols need production-grade RPC

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.

Flat pricing for ZK chain growth

As Linea's ecosystem grows, your RPC usage will grow with it. Flat monthly pricing means your costs do not scale unpredictably as you add more users, more chains, or more features.

Full EVM compatibility

Any Ethereum code works on Linea with a single endpoint change. The same Solidity contracts, ABIs, and tooling all apply.

WebSocket for Linea event subscriptions

Subscribe to new blocks and contract events via WebSocket. Particularly useful for wallet apps that need to update balance displays in real time.

One provider for the ConsenSys ZK stack

BoltRPC supports Linea alongside Scroll and zkSync Era. If you are evaluating or deploying across multiple zkEVM chains, one API key covers all three.

: Linea is built by ConsenSys, the company behind MetaMask, Infura, and Truffle. It is a zkEVM L2 that settles to Ethereum using zero-knowledge proofs. Its deep integration with MetaMask means it has native wallet support out of the box for all MetaMask users.
: A zkEVM (zero-knowledge Ethereum Virtual Machine) is an EVM-compatible blockchain that uses zero-knowledge proofs to verify transaction validity. Unlike Optimistic Rollups, zkEVMs do not require a challenge period, proofs are cryptographically verifiable immediately. Linea is a zkEVM built by ConsenSys.
: Linea is ConsenSys' zkEVM. Scroll is designed for bytecode-level EVM equivalence. zkSync Era focuses on native account abstraction. All are zkEVMs settling to Ethereum, but with different approaches to proof generation and EVM compatibility. BoltRPC supports [Linea](/networks/linea), [Scroll](/networks/scroll), and [zkSync Era](/networks/zksync).
: Yes. BoltRPC provides WebSocket endpoints for Linea at `wss://eu.endpoints.matrixed.link/ws/linea?auth=YOUR_API_KEY`. Use WebSocket for real-time Linea event subscriptions: new blocks, pending transactions, contract events.
: Linea uses ZK proof batches that are submitted to Ethereum for verification. Once the proof is verified on Ethereum, the transactions in that batch achieve finality. This typically takes 1 to 2 hours. Before proof finality, transactions are confirmed by the sequencer, which is reliable for most application purposes but not cryptographically final.
