# The Low-latency Infra Ethereum Builders Trust

BlockRazor provides low-latency Ethereum data and transaction paths for trading bots, searchers, wallets, DEXs, quantitative teams, and node operators.

## Services

- **Public Mempool:** receive publicly propagating pending Ethereum transactions through regional gRPC streams for monitoring, Smart Money tracking, backrun discovery, copy trading, and sniping strategies.
- **NewBlocks:** receive the latest Ethereum block headers, confirmed transactions, and withdrawal data through regional relays.
- **CL/EL Client Sync:** connect Ethereum consensus-layer and execution-layer clients to BlockRazor relays so local nodes can synchronize blocks and world state through an optimized path.
- **Broadcast Tx:** submit a signed Ethereum transaction through regional gRPC relays for fast public propagation. Broadcast Tx does not provide MEV protection.
- **Ethereum RPC:** use standard JSON-RPC methods, private transaction routing, MEV protection, refund workflows, `eth_sendRawTransaction`, and `eth_sendBundle` interfaces.
- **Gas Sponsor:** the supported-chain index also lists Ethereum support for BlockRazor Gas Sponsor. Check the current product documentation before integration.

The official documentation currently lists regional Ethereum relay locations in Frankfurt, Tokyo, and Virginia for Public Mempool, NewBlocks, CL/EL Client Sync, and Broadcast Tx. Select the closest available region and validate it with the production workload.

## Choosing a service

- Use Public Mempool when a strategy depends on pending public transaction signals.
- Use NewBlocks when an application needs structured, confirmed block data.
- Use CL/EL Client Sync when a locally operated Ethereum node needs fresher blocks and world state.
- Use Broadcast Tx when public propagation speed is the priority and MEV protection is not required.
- Use Ethereum RPC when standard JSON-RPC access or a private, protected submission path is required.

Service availability, pricing, limits, interfaces, and regional endpoints can change. Verify current details in BlockRazor Docs before integrating.

## Frequently asked questions

### Which Ethereum service should a trading bot start with?

Start with Public Mempool when the strategy depends on pending signals. Add NewBlocks for confirmed data, CL/EL Client Sync for fresher local state, and Broadcast Tx or Ethereum RPC for submission.

### How is CL/EL Client Sync different from NewBlocks?

NewBlocks pushes structured block data to an application. CL/EL Client Sync connects your own Ethereum clients to BlockRazor relays so the local node can update blocks and world state earlier.

### Does Ethereum Broadcast Tx provide MEV protection?

No. Broadcast Tx enters public propagation and prioritizes lower-latency sending. Use BlockRazor Ethereum RPC when a private, protected path is required.

### Where are the Ethereum regional relays?

Current documentation lists Frankfurt, Tokyo, and Virginia. Choose the relay closest to the application or node deployment and validate it with production traffic.
