| To prove a stablecoin was backed you'd probably do the following: 1) review the processes and controls which operate the business to check they were operating correctly for the period under review 2) interview the various key stakeholders to assess competence and get representations 3) perform substantive testing over the collateral balance for the whole period. Eg daily bank reconciliations. Get third party confirmations for EVERYTHING. 4) perform a contingent liabilities review and a legal review. 5) see if there are any related party transactions 6) do a going concern assessment The key thing would be to check existence, completeness and valuation of collateral and existence and completeness of liabilities (issued tokens). Depending on what the assets are that would entail different procedures. For tether I would want to see their whole CP portfolio to perform a thorough credit risk and systemic risk assessment. Do some modelling to understand valuation implications under various scenarios. Is worth noting that it's not feasible to do this on a monthly basis because it's so onerous. Hence why probably they just do monthly attestations. I would expect that the legal entity which issues the tokens and holds the collateral is audited at least once a year. Never knew my audit knowledge would ever be useful/interesting :) Cheers |
