# Cronos Overview

> Cronos EVM blockchain data on Dune

## What is Cronos?

Cronos is an EVM-compatible Layer 1 blockchain built by Crypto.com. It runs on the Cosmos SDK with Ethermint, giving developers Ethereum-style smart contracts and tooling while connecting to the broader Crypto.com ecosystem. Dune indexes Cronos under the `cronos` schema namespace with standard EVM raw tables and ABI-decoded contract data.

## Key Features

* **EVM compatibility**: Deploy and interact with Solidity contracts using familiar Ethereum tooling (Hardhat, Foundry, etc.).
* **Cosmos interoperability**: Cronos is IBC-enabled and connects to the Crypto.org Chain hub for cross-chain asset flows.
* **DeFi ecosystem**: Home to VVS Finance, CronaSwap, Tectonic, and other Cronos-native protocols.
* **Low fees**: Sub-cent transaction costs make Cronos suitable for high-frequency DeFi and gaming use cases.

## EVM Specifics on Dune

* **Schema namespace**: `cronos` (query as `cronos.blocks`, `cronos.transactions`, etc.).
* **Chain ID**: `25` (mainnet).
* **Native gas token**: CRO (18 decimals).
* **Raw tables**: `blocks`, `transactions`, `logs`, `traces`, `creation_traces`.
* **Decoded infrastructure**: `cronos.contracts`, `cronos.logs_decoded`, `cronos.traces_decoded`.
* **Standard token events**: `erc20_cronos.evt_*`, `erc721_cronos.evt_*` (when materialized).
