Turn EVM calldata into queryable

One indexer, every source — decoded in real time. Add or remove what you index live, with no YAML and no redeploys.

Why Parseon is different

Change what you index without touching code

Every other indexer makes you edit YAML, rewrite mappings and redeploy just to track a new event. Parseon turns that into a live action — add or remove indexed values on the fly and they apply in seconds.

The old wayRedeploy required

# subgraph.yaml

entities:

- Transfer

+ - Swap # new field

# mapping.ts

export function handleSwap(e) { … }

Edit YAML + rewrite mappings by hand
Rebuild and redeploy the whole indexer
Re-sync from genesis — hours of downtime

With ParseonLive

Live monitors

Changes apply instantly. No redeploy, no downtime.

What Parseon does

Indexing infrastructure that gets out of your way

Point Parseon at any EVM chain and get decoded, queryable data in real time — without building or maintaining the pipeline yourself.

Dynamic, no-code schema

Add or remove indexed events and fields from a live dashboard. No YAML, no redeploys — changes apply in seconds.

Decode everything

Raw calldata and event logs become typed, human-readable functions and parameters — automatically, using on-chain ABIs.

Every source, unified

RPC nodes, Etherscan, Alchemy, Infura and more merge into one consistent stream. No adapters. No glue code.

Real-time & backfill

Stream new blocks the moment they finalize, and replay full history at speed to hydrate your database.

Failsafe routing

Health-scored upstreams with auto-failover, hedged reads and circuit breakers keep data flowing under load.

Query-ready output

Decoded data lands in a schema you can query directly — no post-processing, no lossy transforms.

Multi-chain native

Ethereum, Arbitrum, Optimism, Base, Polygon, BNB, Avalanche — one API surface across every EVM network.

The pipeline

From raw bytes to queryable data

Ingest

Connect any set of EVM sources. Parseon streams blocks, receipts and logs from all of them at once.

Decode

Calldata and events are resolved against ABIs into typed, structured records — instantly.

Route

A health-scored multiplexer deduplicates, hedges and fails over so the stream never stalls.

Query

Decoded data lands query-ready. Read it from your backend, dapp or analytics in real time.
