Deliverable Preview

The attestation package.

Three documents. Two audiences. This is what lands with your CPA every reporting period. Populated with January 2024 USDC sandbox data: the same period used in TCB's proof-of-process validation.

The L1 Executive Summary and L2 Reconciliation Exhibit show what the issuer and CPA receive each cycle. Part E is the permanent reference document your CPA uses to make the attestation defensible.
