Collaterals
RAI Dollar runs 8 independent collateral branches on mainnet. Each branch is its own CDP market — its own trove list, Stability Pool, interest rate, and risk parameters — so stress on one branch is contained and can't cascade into another. This is the at-a-glance table of what you can borrow against and on what terms.

Reading the columns
- MCR — minimum collateral ratio to keep a trove open; fall below it and you're liquidatable. CCR and SCR are the critical-system and shutdown ratios.
- Liquidation penalty — the collateral premium taken when a Stability-Pool offset liquidates your trove. Redistribution liquidations carry a higher penalty — see the full parameters.
- Redemption fee — the base fee charged when RD is redeemed against the branch.
- Bootstrap ceiling — the branch's RD debt cap during the 14-day bootstrap period;
maxBorrowis fixed at this value until bootstrap ends. - Util. target — the branch's target share of total system debt. The rate controller steers each branch toward its target via the delta-rate offset; the eight targets sum to 100%.
- Blacklistable — the collateral token can freeze addresses or is upgradeable (issuer-controlled tokens). On these branches, BorrowerOperations runs a zero-transfer probe on debt-increase paths to shutdown the branch, in order to isolate this collateral failure from the system.
