What is the MegaETH RPC URL?

The MegaETH RPC URL with BoltRPC is https://endpoints.boltrpc.io/rpc/YOUR_API_KEY/megaeth. Replace YOUR_API_KEY with your API key from dashboard.boltrpc.io. The chain ID is 4326.

How do I add MegaETH to MetaMask?

Open MetaMask, go to Settings, then Networks, then Add Network, and enter: Network Name: BoltRPC MegaETH, RPC URL: https://endpoints.boltrpc.io/rpc/YOUR_API_KEY/megaeth, Chain ID: 4326, Currency Symbol: ETH.

Is MegaETH EVM compatible?

Yes. MegaETH runs the EVM: Solidity contracts deploy without modification and standard tooling works out of the box. Only the RPC URL and Chain ID (4326) change.

What makes MegaETH different from other L2s?

Speed, by architecture. MegaETH separates node roles and produces mini-block state updates in milliseconds instead of full blocks every one or two seconds.

What gas token does MegaETH use?

MegaETH uses ETH for gas, like Ethereum and most of its Layer 2 ecosystem.

Does BoltRPC provide MegaETH archive and trace access?

Yes. MegaETH is served with full archive depth plus trace_* and debug_* methods, historical state, full transaction traces and debugging on the standard endpoint.

Does BoltRPC support WebSocket for MegaETH?

Yes. BoltRPC provides WebSocket endpoints for MegaETH at wss://endpoints.boltrpc.io/ws/YOUR_API_KEY/megaeth. On a real-time chain, WebSocket subscriptions are the recommended default.

What MegaETH is Built For

MegaETH’s premise is that blockchains should feel like servers: state updates in milliseconds, not seconds. It reaches that with a specialized node architecture: a high-performance sequencer executes transactions in real time and streams mini-block updates, while replica nodes serve reads. That pushes the EVM toward the latency of a conventional backend. That makes it the natural home for applications that were previously impossible on-chain: order-book exchanges, real-time games, streaming payments and anything where a one-second block time is nine hundred milliseconds too slow. It stays EVM compatible, so Solidity contracts and standard tooling carry over. The catch for infrastructure: a chain that updates every few milliseconds produces state faster than any polling loop can follow, so WebSocket streaming stops being an optimization and becomes the integration model.

Common Use Cases on MegaETH

On-chain order books and trading Millisecond state updates make central-limit-order-book exchanges viable on-chain. Their market makers and takers read book state continuously, a latency-sensitive workload where the RPC round-trip is part of the spread.

Real-time games and interactive apps Games that settle every action on-chain need reads that keep up with gameplay. WebSocket streams push state to game servers the moment it changes.

High-frequency DeFi Liquidations, arbitrage and rebalancing compress from seconds to milliseconds. Bots on MegaETH compete on infrastructure quality more than on strategy.

Simulation and debugging pipelines Full trace and debug support means CI pipelines and risk systems can replay transactions step by step against real chain state without running an archive node.

Built for teams that ship on MegaETH.

Full archive plus trace and debug

BoltRPC serves MegaETH with full historical state and both trace_* and debug_* method families, the deepest capability tier we measure. Query any state at any block, trace any transaction, all on the standard endpoint.

Built for real-time workloads

On a chain with millisecond mini-blocks, your RPC layer is the bottleneck if it isn't engineered for it. BoltRPC's infrastructure sustains the concurrent, high-frequency read patterns that real-time apps generate.

WebSocket-first integration

Subscribe to blocks, transactions and events over WebSocket at no extra charge. At MegaETH's cadence, streaming beats polling on freshness and on request volume, often by orders of magnitude on both.

EVM compatibility, zero migration friction

MegaETH is EVM compatible. Contracts, scripts and infrastructure written for Ethereum work with the usual changes only: RPC URL and Chain ID 4326.

Predictable pricing at high frequency

Real-time applications make a lot of calls. Every method has a fixed, published RU weight, so a high-frequency workload has a predictable monthly cost instead of a surprise invoice.
