Video walkthrough

The below walkthrough provides an overview of a number of its key features.

A tour of Chainlens

Chainlens provides an intuitive user experience, driven by the menu on the left-hand side of the screen. Clicking on the relevant menu item will take you to the associated page.

Dashboard

When you browse to a Chainlens instance, you are presented with a dashboard. The Chainlens dashboard provides a summary of key metrics of the blockchain contracts, including:

Total transactions, token contracts and peers
Graphical transaction count broken down by transaction type (contract creation, contract transaction, currency transfer)
Most active contracts
Fungible (ERC20 and ERC777) versus non-fungible token contracts (ERC721)

NFTs

The NFTs view provides a view of all NFTs deployed on the network. These are tokens that adhere to the ERC-721 and ERC-1155 Ethereum standards respectively.

When you click on a specific NFT, you are taken to the collection view for that NFT.

You can refer to the dedicated section in the docs on NFTs for more information.

Tokens

The tokens view provides a view of all fungible, ERC-20 tokens deployed in the network.

If we click on one of our tokens, we get more information about it (as in the Contracts view).

Here you can see the attributes of the token.

You can also see details of the transfer events that have taken place for that token and who the top holders are.

Accounts

The accounts view displays all active accounts on your network.

Accounts are arranged by their balance in the tokens native currency, with the largest balance accounts first. Its also possible to sort accounts based on the:

Tokens
NFTs
Transactions

Click on an account will take you to the account-specific view for it.

This contains details of the transactions, tokens and NFTs associated with the account.

Contracts

The contracts view displays all contracts that have been deployed to your network.

Here you can see details of all contracts deployed to the network. Those contracts that comply with well-defined interfaces are automatically tagged with a type in the Type column to reflect this. For example, ERC20, ERC777 for fungible token contracts, ERC721 for non-fungible token contracts, ERC1155 for hybrid tokens (which defines both fungible and non-fungible tokens) and Custom for those that have not been registered in the contract registry.

The Name column provides the contract name if the contract is registered in the Chainlens contract registry. To learn more about the contract registry, head here.

When you click on a contract, you are taken into the contract details page which has various information about the contract.

Here you can see details of all transactions associated with the contract and events emitted by these transactions. If the contract is registered in the registry, events and their parameter names and values will be decoded.

Private transactions are labelled with a Private label. They will only be decipherable if the node that the Chainlens instance is connected to is privy to the transaction.

Events

The events view provides details of all events taking place on the blockchain.

When you click on the Address or Transaction Hash associated with an entry it will take you to the relevant smart contract address or transaction view in Chainlens.

Transactions

The Transactions view provides the details of individual transactions, including private transactions when supported by your blockchain.

Clicking on a transaction will take you to the transaction details view.

When you view transaction details you'll find view lower-level details, such as the input byte code.

Blocks

The blocks view provides details of all blocks being generated on the network.

Clicking on a block will take you to the block details view, which displays the transactions in the block and other details.

As with the transactions view, technical details are available here too under the Additional Details menu. Here you can see details such as the block difficulty and gas consumed.

Accounts

Clicking on an address that is not associated with a smart contract, i.e. it holds Ether, will bring up the account view, which displays the current balance and transactions associated with the account.

Search

The search box in the top-right corner of the screen allows you to search by various criteria, including:

Contract address
Account address
Transaction hash
Block hash

If a match is found the associated contract, account, transaction or block details will be displayed.

Advanced sorting and filters

Another key feature is the addition of sorting and filters in Chainlens. This enables users to find very active tokens or contracts by sorting or filtering by key attributes. For instance, contracts can be sorted by transaction count, creation date or last execution.

Each of the different views in Chainlens provides relevant sorting functionality.

The filters provided also allow you to view subsets of the available data, such as only displaying ERC-721 or ERC-1155 tokens in the Tokens view.

As with the sorting functionality, all of the different views in Chainlens have various filters you can apply.
