Digital asset reconciliation is the control that proves a firm's books agree with what actually exists on the blockchain and at its service providers. It is a form of reconciliation with three sides rather than two: the firm's internal ledger of client and house balances, the balances of the wallet addresses it controls as shown by on-chain data, and statements from any outside custodian, exchange or broker. Because many platforms pool client assets in shared wallets, the internal ledger is the only record of who owns what, and it must sum to the on-chain total.
The work has features that traditional securities do not. Markets run continuously, so there is no natural end of day and firms choose a cut-off time. Network fees, staking rewards, airdrops and failed transactions create entries with no trade behind them. Results support wallet reconciliation, client asset rules, audits and any reserve attestation the firm publishes.
