Arbitrum Network

Introduction

Arbitrum Arbitrum is an L2 scaling solution for Ethereum. It is a suite of Ethereum scaling solutions that enables high-throughput, low cost smart contracts while remaining trustlessly secure.Abitrum possesses the following features:

  • Trustless security: security rooted in Ethereum, with any one party able to ensure correct Layer 2 results
  • Compatibility with Ethereum: able to run unmodified EVM contracts and unmodified Ethereum transactions
  • Scalability: moving contracts’ computation and storage off of the main Ethereum chain, allowing much higher throughput
  • Minimum cost: designed and engineered to minimize the L1 gas footprint of the system, minimizing per-transaction cost.

Supported endpoints

  • api.covalenthq.com/v1/{chainId}/address/{address}/balances_v2/

    • Get token balances for address. Return a list of all ERC20 and NFT token balances including ERC721 and ERC1155 along with their current spot prices.
  • api.covalenthq.com/v1/{chainId}/address/{address}/transactions_v2/

    • Retrieve all transactions for address including their decoded log events. This endpoint does a deep-crawl of the blockchain to retrieve all kinds of transactions that references the address.
  • api.covalenthq.com/v1/{chainId}/address/{address}/transfers_v2/

    • Get ERC20 token transfers for address along with historical token prices.
  • api.covalenthq.com/v1/{chainId}/tokens/{contract_address}/token_holders/

    • Return a paginated list of token holders contract_address as of any historical block height.
  • api.covalenthq.com/v1/{chainId}/events/address/{contract_address}/

    • Return a paginated list of decoded log events emitted by a particular smart contract.
  • api.covalenthq.com/v1/{chainId}/events/topics/{topic}/

    • Return a paginated list of decoded log events with one or more topic hashes separated by a comma.
