Indexed CronosBlockchain Data
Cronos is a Cosmos SDK chain with an Ethermint EVM on top, so CRO pays gas against twenty-byte addresses while every account also carries a bech32 form and IBC stays open.
How to query Cronos data with SonarX
Instant Data Share
Available todaySnowflake, and file dumps to your object storage
Query Cronos blockchain data with plain SQL from a live database inside your own Snowflake account, populated with the indexed chain dataset. There is no pipeline to build and no second copy to store. The same dataset ships as file dumps to your own object storage for lakes and warehouses that are not Snowflake.
- Full history as a Snowflake data-share
- File dumps to S3 or your own object storage
- Real-time delivery, current to chain tip — on request
Used for:
- Analytics teams already on Snowflake that want Cronos data beside their existing tables
- Fund accounting and treasury reporting that reconciles against a fixed history
- Cross-chain questions answered in one SQL statement instead of one query per chain
- Loading Cronos history into BigQuery, Databricks, Redshift or a Spark lake
- Replacing a self-hosted indexer and the engineering time that keeps it running
- Serving one governed dataset to several desks without copying it per team
Kafka Streaming
Enabled on requestEvent stream
Consume Cronos activity as a continuous stream of normalized records, produced as the chain is indexed instead of polled for.
Used for:
- Trading and execution systems that act on Cronos activity within seconds
- Fraud and anomaly detection that has to fire before settlement
- Live dashboards and alerting on Cronos wallet or protocol activity
- Feeding a stream processor that already reads from Kafka
- Keeping an internal store hot without waiting for a batch window
- Event-driven services that would otherwise poll on a timer
Balances
Available todayTables and REST
Read what a Cronos address held, either as it stands now or exactly as it stood at a past block or timestamp.
- Point-in-time balance tables, as at any block or timestamp — on request
- Real-time balances API for latest and historical balances
- Batch API for wallets, tokens and balances in bulk
Used for:
- Reconstructing Cronos portfolios and NAV as at a reporting date
- Audit and reconciliation work that has to be repeatable months later
- Wallet and portfolio products that render Cronos balances on page load
- Compliance checks that read one Cronos address at one block height
- Refreshing holdings for a whole book of accounts on a schedule
- Tax and cost-basis workflows that need holdings at each event
Realtime API
Enabled on requestREST over the indexed dataset
Query indexed Cronos records over REST, reading the same dataset the share reads, with no warehouse in the path.
Used for:
- Applications that need one answer rather than a table scan
- Customer-facing screens where query latency is visible to a user
- Services that have no data warehouse and do not want to run one
- Prototyping against production data before committing to a share
- Backend checks that run per request instead of per batch
- Teams that want indexed Cronos data behind their own API layer
Cronos data: frequently asked questions
What is Cronos?
Cronos launched its mainnet on 8 November 2021 as an EVM chain built on the Cosmos SDK, with Ethermint providing the execution layer. Blocks are committed by a BFT validator set, which means a committed block is final and there is no probabilistic settlement to wait out. The native asset is CRO, which pays gas here and also circulates on Cronos POS, a separate Cosmos proof-of-stake chain. The EVM side answers to chain ID 25. Because the chain is Cosmos underneath and Ethereum on top, each account carries two representations: a bech32 address for the SDK modules and a twenty-byte hex address for contracts. IBC is enabled, so assets can enter from other Cosmos networks through a protocol handshake rather than through a contract call.
Cronos data on SonarX
SonarX indexes Cronos blocks and headers, transactions and receipts, decoded event logs, execution traces including internal value transfers, and token transfers and balances, in the normalized model used on every chain SonarX covers.
Full historical coverage is available today as a data-share or a file delivery. Real-time delivery is enabled on request. The real-time balances API and the batch wallets, tokens and balances API are available for Cronos, and the rest can be enabled on request. Kafka streaming can be enabled for Cronos on request.
How SonarX indexes Cronos
Two Cosmos habits break an Ethereum-shaped pipeline here. Addresses come in two encodings of the same account, so any holder-level aggregate has to reconcile bech32 and hex before it counts anything, or it reports one owner as two. And value can move without an event: an IBC transfer or a module-level send is recorded by the chain rather than emitted as an ERC-20 log, so a token view assembled only from decoded logs is missing balance changes that a reconciliation will later find. Instant BFT finality is the compensation, since nothing indexed here has to be withdrawn after a reorg.
What teams build with Cronos data
Retail flow reconstruction is the common request: this chain’s traffic is dominated by consumer-scale swaps, transfers and gaming activity, which means many small records and a strong case for aggregation in a warehouse. Position-level DeFi analytics is the second, and needs decoded events joined to internal transfers. Cross-ecosystem asset tracing is the third and is specific to a chain with IBC: an asset that arrived from Cosmos has provenance outside this chain, and a full origin story is a two-network question that Sei raises in the same way. Treasury and transaction monitoring for businesses holding CRO runs on the same records.
Getting Cronos data from SonarX
Tell us the delivery target, how far back you need and how fresh it has to be, and the share is scoped against that. History from the 2021 launch is available now, and the Cosmos side of an asset’s route can be scoped alongside it. The published coverage matrix for every network SonarX indexes lives in the data documentation, and the rest of the catalogue is at all indexed chains.
Is there a Cronos data API?
Yes. Real-time and batch APIs over indexed Cronos data are available today, covering historical and latest balances and wallet, token and balance lookups in bulk. They read from the same indexed dataset as the Snowflake share and the file delivery, so an API answer and a warehouse query agree.
How do I get Cronos data into Snowflake?
SonarX provisions a data-share into your own Snowflake account. The share appears as a database you query with SQL, so there is no pipeline to build and no second copy to store, and it stays current as SonarX advances the indexing pipeline.
How far back does Cronos coverage go?
The historical data-share and file delivery cover the chain from its mainnet launch on 8 November 2021 forward and are available today. Real-time delivery keeps the same dataset current to chain tip and is enabled on request.
Why does one Cronos account have two addresses?
Because the chain is a Cosmos SDK chain running the EVM. The same key produces a bech32 address for the Cosmos side and a twenty-byte hex address for the EVM side, and the two are different encodings of one account. Any join that treats them as separate holders double counts, so indexed Cronos data reconciles them rather than leaving the reader to convert.
Is this Cronos or the Cronos POS chain?
This page covers the Cronos EVM chain, where Solidity contracts run and gas is paid in CRO. Cronos POS is a separate Cosmos proof-of-stake chain that also uses CRO, with its own blocks and its own records, so activity there is not part of this dataset and is scoped on its own.
