Ironsource Unity waterfall integration - pubnative/pubnative-hybid-android-sdk GitHub Wiki
For the integration of Ironsource on Unity, follow their documentation:
https://developers.is.com/ironsource-mobile/unity/levelplay-starter-kit/
Once this is done, and the placements are already existing, the following is required: Add the HyBid SDK and the Ironsource Adapter to your dependencies, within AndroidPackages:
<androidPackages>
<androidPackage spec="net.pubnative:hybid.sdk:3.3.0">
<repositories>
<repository>https://verve.jfrog.io/artifactory/verve-gradle-release</repository>
</repositories>
</androidPackage>
</androidPackages>
<androidPackages>
<androidPackage spec="net.pubnative:hybid.adapters.ironsource:3.3.0">
<repositories>
<repository>https://verve.jfrog.io/artifactory/verve-gradle-release</repository>
</repositories>
</androidPackage>
</androidPackages>
The steps required to be done on the IronSource Dashboard can be found here:

Once this is done, just use the desired ad units in your already set ad placements in Unity.
