Local pooling contracts appear, but bridge-assisted Ethereum mixer inheritance is the larger practical issue.
Privacy tools that matter on Polygon
A wallet that bridged from an Ethereum Tornado withdrawal carries inherited exposure on Polygon when the bridge link is proven.
Direct use versus inherited outputs
Micro-fee hop chains are cheap here; demand entity attribution before calling them mixers.
When batching is not mixing
Escalate attributed pool or bridged Tornado-class routes under policy. This information is not legal or financial advice.
