Espresso demonstrated at the Digital Assets Summit (DAS) by deploying 5 independent chains on the Espresso network to simulate cross-chain collateral management processes. The demonstration showed that the engine can reprice over one million collateral positions in a market crash scenario and trigger cross-chain transactions when thresholds are reached: automatically replenishing collateral when additional collateral is available, and freezing risk exposure when insufficient; the complete disposal process is completed within 10 seconds.
