treasury reconciliation: chain, custodian and ledger
Treasury reconciliation in a business has one more source than in any other business: the chain itself, which is authoritative about what happened and silent about why. This page sets out the method EOS applies, which a finance team can follow with or without the platform.

11. Take every source on the same cut-off
A chain balance is a balance at a block. A custodian statement is a balance at a time. A ledger entry is a balance at a posting date. Reconciliation starts by naming one cut-off and reading each source as of that moment, with the block height or timestamp recorded beside the figure. Most "discrepancies" are differences of cut-off, and they disappear here.
22. Bring the records to one shape
A position on the chain, a holding at the custodian and a line in the ledger describe the same thing in three vocabularies. The mapping is recorded, so it can be checked.
33. Keep the disagreement
Where the three still differ after the cut-off is aligned, the difference is the finding, not a problem to hide. It is shown with all sides and their dates. The usual causes: a transfer in flight at the cut-off, a fee booked on one side only, a token the ledger prices differently from the venue, a custodian sub-account the ledger does not model.
44. Settle with authority, on the record
A named person with authority under a recorded policy decides which figure counts and why. The decision, the person, the policy version and the evidence they saw are recorded together. Nothing is overwritten; the losing figure stays in the record as the figure that lost.
55. Produce evidence an auditor can verify alone
The month's reconciliation becomes an evidence pack: the figures, their sources, the mappings, the disagreements and the decisions, sealed so that an auditor can verify it offline without asking anyone. What the evidence pack holds.
66. Measure the next month against this one
The gap between the expected and the measured outcome is recorded, so the next reconciliation starts from a known baseline rather than a fresh export.
7What EOS adds to the method
EOS does the reading, the normalizing and the keeping of disagreement, and it routes the settlement to the person with authority with the evidence attached; the person still decides. Chain data comes from the providers you configure. Digital asset operations for enterprises describes the wider operating picture.
