Bank guarantee (v1)
Bank guarantee is one of Demiton's published registers for Australian civil construction. Bank guarantees and other security instruments given or held under a contract. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.
Part of Counterparties in the register catalog.
