Why SChain Validation Deserves More Attention in Programmatic

This article from IAB Tech Lab discusses the importance of the SupplyChain object (schain) in programmatic advertising for ensuring supply path transparency. It explains how schain records every entity that handled a bid request, but emphasizes that declaring a chain is not the same as validating it. Validation involves cross-checking each node against the public ads.txt and sellers.json files. The article highlights common issues like fabricated hops, duplicate seller IDs, and obfuscated bundle IDs. It urges exchanges, SSPs, and DSPs to implement and continuously validate schain to combat ad fraud, build trust, and protect revenue. The piece also mentions IAB Tech Lab's automated validation service and a proposed 1.1 update to the spec.

• The SupplyChain object (schain) records every entity that handled a bid request, starting from the original publisher.
• Validation of schain involves checking each node against public ads.txt and sellers.json files.
• A reseller must insert their own node into the chain when taking custody of a bid request, or the object becomes invalid.
