## Requirements for Base Bidding

{% hint style="info" %}
In order to create and run Base Bidding task each User will need the Butler Basic Access ([Subscription or Lifetime NFT](https://docs.nftbutler.io/nft-butler/nft-butler/getting-started/get-access)) as well as the [PRO Access](https://docs.nftbutler.io/nft-butler/products-and-services/pro-access) on top.

Further you're wallet needs to hold [WETH on Base](#convert-eth-weth-to-base) L2 chain.
{% endhint %}

## How does Base Bidding work?

Bidding on Base Collections via OpenSea is pretty much the same as Bidding on Ethereum Collection. However there are still a few points to note which will also very likely change soon:

* Wallets overview will not show Base ETH / WETH balances.
* Bidding tasks cannot check how much funds are available in your bidding wallet. Therefore it will always try to bid up to your max bid price. Bids will fail if bidding funds are insufficient.
* Approvals for Listing automation have to be done manually on each Collection first. Otherwise Auto Listing tasks will fail to send listing orders.

All other Features are supported same as on Ethereum Collections:

* Adding collections to Search engine
* [Instant Counter Bidding](https://docs.nftbutler.io/nft-butler/features/instant-counter-bidding)
* Collection Trait Offer Tasks
* Token bidding Tasks / Manual bidding tasks
* Performance Overview / Flips / Notifications and Inventory
* [Security Features](https://docs.nftbutler.io/nft-butler/setup/security-features)
* [Auto Listing ](https://docs.nftbutler.io/nft-butler/features/bidding-and-autolisting)configuration on Bidding Task
* [Auto Listing Engine](https://docs.nftbutler.io/nft-butler/features/auto-listing-engine)

## Convert ETH / WETH to Base

In order to be able to bid with WETH on Base you'll have to birdge some of your WETH to the Layer 2 Base Blockchain.

* Metamask is offering a direct Briding Service between different L2 Chains and Base is one of the supported Chains here. Simply use it with the following link:\
  <https://portfolio.metamask.io/bridge>

After briding your ETH / WETH from Ethereum mainnet to Base L2 you'll also have to perform a **manual bid on OpenSea**. Otherwise tasks with Butler will fail due to missing WETH approvals.

{% hint style="info" %}
Infura does currently not support Base L2 Chain via their free RPC servers. This is why Butler will **not show your Base ETH / WETH Balance** on the Dashboard or Wallets Overview.

Also Tasks will not be able to check in advance how much WETH is available in your Wallet. Butler will simply fire your bids and if your balance is not high enough the Bid will be rejected.
{% endhint %}

## Create Search Engine Task

{% hint style="info" %}
If you don't find your favorite Base collection on the Butler search engine, feel free to [add](https://docs.nftbutler.io/nft-butler/setup/add-collection-to-butler) it with the Button on top of the search engine.

With the Blockchain Filtering option you can filter the collections based on Blockchain as shown below.
{% endhint %}

<figure><img src="https://156458129-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FUpGMSshbhuSUXHzoKrTn%2Fuploads%2FjwIFsEmHiHxmNKi4yT1O%2Fimage.png?alt=media&#x26;token=1a081aae-b0e6-4040-8022-2957a7f75cc2" alt=""><figcaption><p>Filtering for Base collections</p></figcaption></figure>

The above screenshot shows available Base collections filtered by Blockchain on the left. The highlighted buttons will provide the following features:

* 1st Button "Show all Traits": Drilldown into the Traits view of the collection to create trait based bidding tasks
* 2nd Button "Check Collection Stats": Will provide a collection floor price graph for OpenSea and Blur (up to 2 months) as well as top Collection Bids and the last Sales events.
* 3rd Button "Create Collection CTO": With this button you can create a [Collection Bidding Task](https://docs.nftbutler.io/nft-butler/task-types/collection-trait-bidding-cto)
* 4th Button "Create Token Task": Here you can create a [Token Bidding Task](https://docs.nftbutler.io/nft-butler/task-types/token-bidding)

## Create Manual bidding Task

Base bidding tasks can also be created as[ Manual Task](https://docs.nftbutler.io/nft-butler/task-types/manual-token-id-bidding) providing the collection link, smart contract and a list of token ids:

<figure><img src="https://156458129-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FUpGMSshbhuSUXHzoKrTn%2Fuploads%2F7lUXg4fE8ezIdjWPmFXo%2Fimage.png?alt=media&#x26;token=bb56a3f8-2ded-424e-9c51-f14316760de1" alt=""><figcaption><p>Create Manual Token Bidding Task</p></figcaption></figure>

### Marketplace & Blockchain

With the required[ PRO Access](https://docs.nftbutler.io/nft-butler/products-and-services/pro-access) you can choose the target Blockchain to "Base" with OpenSea as the Marketplace:

<figure><img src="https://156458129-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FUpGMSshbhuSUXHzoKrTn%2Fuploads%2FsMYUpyQ2AoScORvyjI2b%2Fimage.png?alt=media&#x26;token=a6ca52fb-668b-41a2-bfd6-80ac44f6efbb" alt=""><figcaption><p>Choosing Base as Bidding Blockchain</p></figcaption></figure>

* Now to create your first Base Bidding Task you'll basically have to copy & past the Link to the Base Collection in Butler and fill the "Token IDs range" field with a list of Token IDs you'd like to bid on
* To support finding all Token IDs of a specific Trait we have two very usefull Community Bot features availbe for Members in our Discord:\
  [/traits](https://docs.nftbutler.io/nft-butler/products-and-services/discord-bot/traits)\
  [/tokenscan](https://docs.nftbutler.io/nft-butler/products-and-services/discord-bot/tokenscan)

{% hint style="info" %}
Make sure to "Fetch Data" once you've copied the Link to the collection. It will fetch Collection Stats and Last Sales information on the left side.
{% endhint %}

* For all the Manual token task configuration options please refer to [Manual Token Bidding Page](https://docs.nftbutler.io/nft-butler/task-types/manual-token-id-bidding)

## Dashboard & Wallt Details

* Base Bidding Tasks will be part of the Live Bidding Activity Feed on the [Dashboard Overview](https://docs.nftbutler.io/nft-butler/features/dashboard)
* Target link will link to OpenSea as usual
* However the wallet percentage for the WETH limits are not taking Base bids into account
* Wallet Details will show active bids on Base

{% hint style="info" %}
Infura does currently not support Base L2 Chain via their free RPC servers. This is why Butler will **not show your Base ETH / WETH Balance** on the Dashboard or Wallet Details here.

Also Tasks will not be able to check in advance how much WETH is available in your Wallet. Butler will simply fire your bids and if your balance is not high enough the bids will be rejected.
