Your dashboard, your payment provider and your accountant hold three numbers that are each correct on their own terms, and none of them is the balance. I find where they stop agreeing, and I name the failure mode behind each gap.
What you get
- A written report naming every place your reconciliation can drift, with the mechanism behind each one, not a list of symptoms.
- For each: what it looks like from outside, what proves it, and what it costs to fix.
- A ranking by what it costs when it fires, so you fix in the right order.
- A working check where one is cheap to add.
Where this comes from
Custodial systems across four chains, double-entry ledger cores, and pipelines that turn bank statements into posted entries. A reconciliation loop I built compares obligations to users against on-chain balances every five minutes and freezes withdrawals automatically when the solvency invariant breaks.
What I need from you
Read access to the ledger schema and one export from each side that should agree. No production credentials.
Delivery: five working days.
