## Historical Contracts

{% hint style="danger" %}
These contracts have been deprecated and should not be used. They are listed here for data analysis and tracking purposes only.
{% endhint %}

{% hint style="info" %}
From 10/23/2022 until 1/15/2022, the AssistingAuction contract on Harmony also contained the `summonCrystal` and `open` functions and related events for the summoning of all Heroes, including those summoned through an Assisting Auction. On 1/15/2022, these were migrated to the [Hero Summoning](https://devs.defikingdoms.com/contracts/summoning/hero-summoning) contract.
