Chain of custody

Declare → transfer → transform → prove Continuous custody for yarn to garments

RankinSoft Tracer™ keeps documents on every handoff — feedstock declaration through finished goods, with honest gaps when a stage is missing.

  • Feedstock declaration
  • Wallet sends
  • Mining / Update Token
  • Traceability report
