The Contract view is packed with contract specific details. See its transactions, messages, events and get a rundown of the ERC20 tokens held in that contract. Since Starknet implements account abstraction by default, all accounts are smart contracts, and the contract view provides deep insight on those properties.
Contract view

In the tab Read contract, you can see and trigger the view functions of the contract, to check its state. With the Write Contract tab, our partnership with ArgentX wallet enables you to start transactions to trigger functions that change the contract's state.
In the Code section, Voyager displays the bytecode of that contract, and can also show the contract’s human-readable source code. In order to show the source code, Voyager provides the Contract Verification Tool, where anyone can upload the source code for a contract deployed to a specific address. Voyager compiles and verifies it against the on-chain bytecode and after that, the source code is available to read in the Code tab, with source code verification status at the top of the page.

The Transaction view provides deep insights into the anatomy of a transaction. Users land on the overview tab which provides essential information. Explore the transaction more in-depth by browsing to its internal calls, the included events or messages!
PS: Voyager comes with a slick dark-mode!
