Indexing EVM Chains with The Neighborhood

Ethereum and its expanding family of EVM-compatible chains have become the backbone of Web3. From Ethereum Mainnet to Base, Arbitrum, Optimism, Polygon, Avalanche, and many others, each chain carries its own developer community and data-rich ecosystem. For product teams and data engineers, this growth means one thing: how do you reliably index and unify data across all these chains without the burden of maintaining custom infrastructure for each one?

The Indexing Company built The Neighborhood, a distributed compute network for high-performance indexing. It supports all major EVM chains today and makes it possible to create pipelines that span multiple chains, combining real-time streams and historical backfills into one coherent dataset.

Why Indexing EVM Chains Is Hard

EVM chains share the same virtual machine, but in practice they differ in RPC implementations, throughput, and ecosystem activity. Data engineers often face: Fragmented datasets across multiple RPCs and providers

• High costs of running custom indexers for every chain

• Rigid APIs or subgraphs that require reindexing when contracts change

• Latency issues for applications that need real-time data

The Neighborhood solves this by ingesting raw block data from any EVM RPC, applying programmable JavaScript transformations, and streaming the results directly into databases, warehouses, or webhooks. Developers stay in full control of the schema and transformations while skipping the overhead of building their own infrastructure.

EVM Chains Supported

The Neighborhood is live across all major EVM chains. The full, always-updated list of supported networks can be found at: docs.indexing.co/networks.

Some of the most popular chains include: Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Linea, ZkSync, and Scroll.

This breadth of coverage allows teams to unify data across the EVM ecosystem with a single pipeline approach.

And while The Neighborhood also supports non-EVM ecosystems such as Solana, Aptos, and Sui, we’ll cover those in a separate article.

Examples of EVM Data You Can Index

Here are some practical pipelines developers build with The Neighborhood:

• Token transfers: ERC20 transfers across Ethereum, Base, Optimism, and others for balance tracking and portfolio tools.

• DEX activity: Swaps and liquidity events from Uniswap, Curve, Balancer, and chain-native DEXs.

• Lending and borrowing: Events from Aave, Compound, Morpho, and other money markets.

• NFT activity: Transfers, mints, and marketplace sales across EVM chains.

• Wallet analytics: Transaction history, token balances, and activity classification for specific addresses.

• Custom contracts: Protocol-specific contracts on any EVM chain, decoded into your own data model.

Low-Latency and Local Indexing for High-Performance Chains

Not all EVM chains are equal when it comes to speed. New high-performance networks like RISE, MegaETH, and Base are pushing the limits of block production and transaction throughput. For these chains, latency becomes critical: traders, DeFi protocols, and real-time dApps cannot afford multi-second delays.

The Neighborhood addresses this with local indexing. Nodes can run close to validators or inside your own infrastructure, processing data directly at the source. This setup provides:

• Sub-second latency for real-time trading and MEV strategies

• Local control over uptime and data quality, reducing reliance on third-party APIs

• Programmable pipelines to decode events and normalize them for immediate downstream use

For developers building on RISE or MegaETH, where performance is the differentiator, local indexing ensures your data pipelines keep up with the chain itself. On Base, where scale and consumer apps drive adoption, local indexing helps wallets and DeFi platforms deliver faster UX without sacrificing accuracy.

Benefits for Builders

Programmable pipelines

Customize exactly what you index and transform, without rigid schemas.

Cross-chain unification

Combine Ethereum Mainnet activity with Base, Optimism, Arbitrum, and more into one dataset.

Real-time and historical coverage

Stream new blocks in sub-second latency while also backfilling history from genesis.

Cost and efficiency

Leverage a horizontally scalable compute network that processes workloads faster and cheaper than centralized cloud setups.

Local deployment options

Run Neighborhood nodes alongside validators or within your own infra for maximum control and performance.

Why This Matters for the EVM Ecosystem

As Ethereum expands through its rollup-centric roadmap and more L2s and sidechains launch, indexing becomes the hidden infrastructure problem that every product team eventually faces. Building and maintaining your own indexers is costly and brittle. The Neighborhood provides a unified solution that scales with the ecosystem and lets teams focus on product, not pipelines.

Getting Started

The Neighborhood supports all major EVMs today and can onboard new ones rapidly. Developers can configure pipelines through our console and APIs, stream data into Postgres, BigQuery, Kafka, or webhooks, and unify analytics across chains.

For product managers, CTOs, and data engineers building on EVM chains, The Neighborhood is the fastest way to go from raw chain data to production-ready pipelines.
