I The console

Every household, one quiet screen.

Positions, mandates and signatures across every custodian you use, reconciled overnight and readable in the morning without a spreadsheet in sight.

Control 01 of 24Quorum signing, 3 of 5 named officers

II Custody

Twenty-four bolts. Twenty-four controls.

Every asset on Aurum Ledger sits behind a door with more locks than it strictly needs. Keep scrolling to turn the wheel.

II Quorum

It opens for a quorum, never for a person.

Three of five named officers sign on hardware keys that never leave the building. Our own engineers cannot move a penny, and we would not want them to.

III The ledger

Written once. Witnessed three times. Never erased.

Every movement is double-entry, chained to the one before it and countersigned by two custodians you did not choose. An auditor can walk a decade of books in an afternoon.

IV Mandates

Priced by the month, never by the basis point.

“We moved two hundred years of books over a weekend. On Monday, the only thing anyone noticed was the silence.”

Constance Aldermere, Chief Operating Officer, Harrow & Vale Private Office

Most of our clients found us the quiet way.

No sales team and no conference stands. A custody officer calls you back within one working day, from a number you can verify.
