Counterparty Discovery

  • • An address alone does not name a VASP
  • • Resolution returns a reachable Travel Rule endpoint
  • • Self-hosted and unattributed cases branch to policy

Pre-Transfer Gate

  • • IVMS101 identity data is exchanged before signing
  • • Only an ACCEPTED decision unlocks the signer
  • • A timeout parks the transfer, never an implicit yes

Irreversible Settlement

  • • The broadcast is the point of no return
  • • Safety lives entirely in the ordering
  • • The exchange is linked to the final tx hash
