Avalanche is 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 processes 4,500+ transactions/second and instantly confirms transactions. Ethereum developers can quickly build on Avalanche as Solidity works out-of-the-box.
A key difference between Avalanche and other decentralized networks is the consensus protocol. Over time, people have come to a false understanding that blockchains have to be slow and not scalable. The Avalanche protocol employs a novel approach to consensus to achieve its strong safety guarantees, quick finality, and high-throughput, without compromising decentralization.

address, return current token balances along with their spot prices. This endpoint supports a variety of token standards like ERC20, ERC721 and ERC1155. As a special case, network native tokens like ETH on Ethereum are also returned even though it’s not a token contract.
address, return all transactions along with their decoded log events. This endpoint does a deep-crawl of the blockchain to retrieve all kinds of transactions that references the
addressincluding indexed topics within the event logs.
AVAX Gas token
The AVAX token is the native token of Avalanche. This is similar to Ether in Ethereum. To interact with Avalanche, AVAX tokens are required to pay gas fees. The Covalent API response returns
gas_* fields in fiat units.
Covalent maintains an on-chain real-time mapping of token addresses between Ethereum mainnet and the Avalanche C-chain. These addresses are used to reverse-lookup prices on Avalanche and also to return the right token logo urls.
Some example of mapped tokens:
|Token||Ethereum mainnet||Avalanche mainnet|
For the current token mapping list, see: https://github.com/ava-labs/bridge-tokens/blob/main/data/eth_token_mapping.csv
For tokens that have a mapping back to Ethereum mainnet, Covalent is able to return the mapped prices.
The following provide infrastructure for this blockchain network:
