Self-Referential Obligations

Why Self-Referential?

Build complex structures without counterparty risk
Lock the structure by accepting your own obligation
Atomically transfer to actual counterparty via swap
Ensures secure construction and settlement

Create obligations with yourself as both obligor and counterpart, then atomically swap them to the real counterparty. See Workflows for complete examples.
