1/ Address Page Overview
Transactions (txs) - table of all txs to/from the address
Internal txs - contract interactions
ERC-20/ERC-721/ERC-1155 txs - latest token txs
Contract - source code
Events - latest emitted contract events
Analytics - wallet stats
Comments - chat

2/ Transaction History
Shows you all txs from/to an address. You can find answers to common questions like:
„How many txs does the address have?“ or "How did the address get funded?"
For instance, exchanges typically have a high number of txs.

3/ Transactions Filter
Looking for something specific? Filter the tx history to/from addresses, block, age, or smart contract calls.
For instance, filtering by age allows you to zoom into all txs that happened before/after a project made an announcement.

4/ Transaction Decoder
Allows you to view the Emitted Events, State Difference, and Execution Trace of any transaction.
Here's the cool part! You can jump directly to the referenced contracts, traces, and functions in the contract code by clicking on them.

5/ Input Data Decoder
Input data of a tx can be useful for info on contract deployments, call parameters, or reading messages on the Ethereum blockchain.
For a tx with input data, hit "Decode Input Data" or view as UTF-8. This will convert it to a human-readable format.

6/ Smart Contract Search
A handy search tool for finding contracts that share similarities. For instance, you can search for contract source codes that have the same deployer address.

7/ Ethereum Code Viewer
When you view a smart contract address on Etherscan you can change the URL from “.io” to “.deth.net”. That will open the code viewer, a very handy tool in VS Code style to view the smart contract code. 👀

8/ Contract Diff(erence) Checker
Lets you compare the code differences between two smart contracts.
An exemplary use case is diffing implementations of delegatecall proxies.

9/ Token Tracker
These pages are available for token contracts. They are useful to get an idea of the largest holders, overall distributions, and in-depth analytics.
Can be useful for identifying addresses based on the tokenomics of a token.

10/ Comments
People may complain about problems or want their ETH refunded. In this process, they often reveal the entity they have interacted with.
