Parameters

Risk numbers live in RiskRegistry. Accounting logic does not. This page is generated at build. Do not type these values by hand.

If an RPC is configured, values come from the live RiskRegistry. Otherwise they come from mock parameters and LaunchParams.sol.

Corporate-action window	3600s	Pause around a split or other corporate action.

IRM slope above kink	8e10 / s	Rate added per unit of utilization above the kink.
Timelock delay	172800s	Wait between scheduling and executing a registry change.
Issuer cap (id 1)	1,000,000,000 USDG (testnet)	Total USDG that can be borrowed against one issuer’s stocks.

How a value changes

Every row above except the timelock delay and the reserve target is a RiskRegistry write. The registry owner is the Timelock. A change is scheduled by the proposer, waits for the delay, and is executed by anyone. Nothing here changes the accounting in Stockline; the core reads the registry at the moment of each call. The timelock delay is immutable on the deployed Timelock. The reserve target is a constant in FeeCollector. Changing either means a new contract and a new registry write.

Timelock queue

The timelock queue is not reachable in this build. Configure ROBINHOOD_TESTNET_RPC or ROBINHOOD_MAINNET_RPC to list scheduled operations from logs. Per-book values are on Books and tiers. Who can call each setter is on Access controls.
