09:00 CET: how we prove reserves every morning
Proof of reserve is two numbers from two parties that must agree, signed by a third, and published even when they don't.
Every morning at 09:00 CET we take the custodian’s statement of what it holds for each issue and the token supply of that issue at the same cut-off. For Corran T-Bill Fund this morning, that was $412,600,000 held at Larkfield Depositary and 412,600,000 CTB outstanding on Stellar.
Aldane Fund Services, the administrator, signs the comparison, not us. The signed attestation is published on the issue page with the statement reference, the block of the supply reading and the difference, which is usually Δ 0.00%.
The day it wasn’t
On 14 August 2026 a custody movement was booked a day late and the two numbers differed. The attestation said so that morning, with a note; the restatement was published the next day. Both lines are still on the record, the one rust point among the last 90. A record with no exceptions in it is usually a record nobody checks.
