What Lerian SISBAJUD does — and does not — do
- It is the judicial-order fulfilment boundary between the Judiciary and the institution’s ledger. It receives court orders by file, resolves the affected accounts, executes the block or unblock on the Midaz ledger, and reports each outcome back to BACEN.
- It does not accept orders over its API. Orders enter only as remittance files delivered through BACEN’s file-exchange channel; the HTTP surface is administrative and observational, never an order-entry path.
- It freezes funds by moving them, not deleting them. A block moves the court-ordered amount from the customer account into a dedicated, per-order block account on the ledger — a balanced double-entry movement — where the funds are held unavailable until an unblock releases them.
- It is multi-tenant from the ground up: one deployment serves many institutions, each isolated so that
institution_idequals the tenant and no order or file crosses an institution boundary.
Who it serves
Lerian SISBAJUD serves banks and financial institutions that must honour judicial asset orders under the CNJ/BACEN SISBAJUD regime. Each institution is a tenant with its own credentials, its own encrypted data, and its own ledger connection, so a single deployment can serve many institutions at once without any of them seeing another’s orders.
