# C-Chain

C-Chain is one of the three chain in the Avalanche network, a short for “Contract Chain”. It is the chain dedicated to the creation of Ethereum-compatible smart contract. It is currently the most populated and complex.

The C-Chain page on Avascan is divided in three sections:

* **Transactions**
* **Blocks**
* **Tokens**

## Transactions

Top left of the page you can see the current total number of transactions on the chain.

You can filter results by:

* **TX type:** Import (TXs bridging in from X-Chain) , Export (TXs bridging out to [X-Chain](https://docs.avascan.info/how-to-use-avascan/x-chain)), ERC20 (TXs involving the trasfer of ERC20 tokens), ERC721 (TXs involving the trasfer of NFTs)
* **Time span:** it is possible to only show txs occurred during a certain time span

The following columns are displayed as results:

* **Hash:** here you can see the TransactionID and the TX sender and receiver
* **Block Age:** how long ago the TX happened and the date and hour of the event
* **Avax Amount:** the amount of $AVAX involved in the TX
* **Status:** represented with three icons Success, Failed or Reverted

## Blocks

Top left of the page you can see the current total number of blocks on the chain

You can filter results by **time span** (already explained above)

The results are displayed in few columns:

* **Height:** the number of blocks before the one involved in the TX
* **Age:** how long ago the block has been accepted onto the chain, with date and hour as well
* **Transactions:** the number of TX in the block
* **Gas used:** gas used in the block
* **Total burned:** the amount of $AVAX burned in the block
* **Volume:** the amount of $AVAX transferred in the block
* **Size:** the width of the block expressed in bytes

## Tokens

In this page you can switch between **ERC20** and **ERC721**; visiting the relative page you can see the total number of tokens present on the Avalanche chain.

You can also filter results switching on and off the **Bridged** button in the ERC20 page in order to show the bridged one only.

The results are displayed in the following columns:

* **Name:** smart contract name
* **Contract address**
* **Created at**: the date and time of the token creation
* **Total supply**: for bridged or multichain tokens, this number only refers to the supply in the Avalanche network
