  1. Wallet Transaction History API tracks all asset transfer events within the Arbitrum blockchain.
  2. Contract Transaction history API gives the entire transaction history for a particular token, given its contract address.
  3. Decoded Transaction API provides an in-depth description of a particular transaction.
  4. Wallet Balance API to track users’ asset balances.
  5. 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.
  6. Token Store API searched by token contract address, this endpoint fetches exhaustive information about a given token.
  7. Block Details API this endpoint returns all the block details of a specified chain when a block number is provided.


Arbitrum 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 Arbitrum, 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.

Smart 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.


Unmarshal has also integrated the Arbitrum 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 Arbitrum.
