Unmarshal Integrates Data Infrastructure Layer for Cronos Network
Unmarshal received funding through the Cronos Ecosystem Grants Program and has now completed integration of a data infrastructure layer for the Cronos blockchain. Unmarshal will provide dApp developers access to its entire product suite and will be a one-stop solution for on-chain data access & notification services along with its data analytics tool, the Parser.
About Cronos
Cronos is the first Ethereum-compatible blockchain network powered by Ethermint and built with the Cosmos SDK, supported by Crypto.com, Crypto.org, and more than 300+ app developers and partners. This effectively allows the chain to exist in the intersection of the Cosmos and Ethereum ecosystems, while enjoying benefits from both ecosystems.
It is an open-source, permission-less layer-1 network aimed at massively scaling the DeFi, GameFi, and overall Web3 user communities. Cronos accomplishes this by enabling developers to instantly port DApps and crypto assets from other chains with low transaction fees (from one cent to a few dimes), high transaction throughput (from hundreds to thousands of transactions per second), and quick transaction finality (5–6 seconds).
Unmarshal’s Tech Stack for Cronos
As part of the integration, Unmarshal has indexed all 5 Million+ blocks created on the chain and continues to live sync the data. A total of 59.7 Million transactions have been executed on the network.
Post indexing and decoding of the data, Unmarshal built frameworks for its API, Parser, and notification services. Let us now explore these in detail, and for the complete list of endpoints, please visit docs.unmarshal.io.
DeFi APIs
- Wallet Transaction History API tracks all asset transfer events within the Cronos blockchain.
- Contract Transaction history API gives the entire transaction history for a particular token, given its contract address.
- Decoded Transaction API provides an in-depth description of a particular transaction.
- Wallet Balance API to track users’ asset balances.
- Price Store API contains endpoints that provide the latest price of a token as well as historical price of the tokens. These can also be LP tokens.
- Token Store API searched by token contract address, this endpoint fetches exhaustive information about a given token.
- Block Details API this endpoint returns all the block details of a specified chain when a block number is provided.
NFT APIs
- NFT Assets API to fetch all NFT assets held by address
- NFT Transactions API gives all transaction details being made on a given wallet
Parser
Cronos support is also enabled on Unmarshal Parser. Parser is a tool which allows developers to index events and functions relating to any smart contract deployed on Cronos, along with other EVM-based chains, onto a relational database. Once decoded and indexed, the data is made accessible through Metabase Dashboards and GraphQL APIs. Users can get started and set up their own indexers on console.unmarshal.io.
Notifications
Unmarshal Smart Notification feature gives instant, at-a-glance alerts for smart contract events that have been triggered. Check out our guide below on how to easily integrate Web3 notifications onto your dApp and send alerts across multiple devices through Firebase.

Upcoming Integration: XScan
Unmarshal will also be integrating Cronos chain with Xscan, a universal aggregated blockchain explorer developed in-house and powered by our very own APIs. Wallet explorers will be able to track their asset portfolios across multiple chains including Cronos.
