The Covalent API Extends Support to Avalanche Bringing Unparalleled Data Accessibility to the Platform

VANCOUVER, March 16th, 2021 - Covalent is happy to announce a technical integration with Avalanche, an open-source platform for launching decentralized applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem.

Avalanche is the first smart contracts platform that confirms transactions instantly, supports the entirety of the Ethereum development toolkit, and enables millions of independent validators to participate as full block producers.

The Avalanche protocol employs a novel approach to consensus to achieve its strong safety guarantees, quick finality, and high-throughput, without compromising decentralization. As a result, developers have been drawn to Avalanche to build powerful, reliable, and secure applications and custom blockchain networks.

Since the launch of the Avalanche-Ethereum Bridge (AEB) on February 8, 2021, smart contract activity on Avalanche has boomed, with transactions increasing by 972% to over 580,000, and unique wallets increasing by 1,681% to top 38,000.

As with all blockchain networks, data accessibility remains an issue given the nature of the data created with each transaction.

However, through this integration, Avalanche is expanding the availability of data on the platform and simplifying the experience for developers who need reliable, high-quality data. Using the Covalent API, developers can pull Avalanche mainnet and Fuji testnest data. You can query either network via the unified API by changing the chainId parameter. This seamless experience significantly enhances the Avalanche developer experience.

Similar to Avalanche, Covalent places significant emphasis on developer experience. Covalent offers a single API that allows you to pull detailed, granular blockchain transaction data from multiple blockchains with no code. This means no complicated SQL queries, no subgraph development and maintenance, and no need to invest in highly-skilled developers to simply retrieve blockchain data. And not to mention, the blockchain data is extensive covering:

  • Token balances per address
  • Historical transactions per address
  • Historical prices by address and ticker symbol
  • Decoded log events

Quote from Ganesh, Covalent's CEO

" Avalanche is building an excellent platform with developers at the heart of it. This integration with Covalent significantly enhances the developer toolkit on Avalanche. The breadth and depth of Avalanche data now available will undoubtedly lead to even more powerful applications being built across the network.

Quote from John Wu, President at Ava Labs

" Reliable, high-quality data is vital to building performant DeFi applications. With Covalent's data on Avalanche, developers building on the platform will be able to build and launch applications faster than ever.
