Oracle Dynamic Protection Mode

Summary

Deploys the new DeviationBoundedOracle (DBO) on BNB Chain mainnet and upgrades the Core Pool Comptroller (Diamond), VAIController, and ComptrollerLens to integrate it. The DBO wraps the existing ResilientOracle with a per-market rolling 15-minute min/max price window, returning protected (min(spot, windowMin), max(spot, windowMax)) pricing on the borrow path when spot deviates beyond the per-market threshold. Phase 1 ships DBO inactive for 23 of 24 assets and active only for TRX as a low-liquidity pilot — Phase 2 (separate future VIP) will activate the remaining assets after the keeper and parameters are validated.

Description

This VIP performs a one-shot deployment of the DBO infrastructure plus the Comptroller and VAIController upgrades required to integrate it. The Comptroller upgrade routes borrow-path pricing through DBO; the liquidation path is unchanged and continues to use the existing ResilientOracle spot price. ACM permissions are granted in a single batch via ACMCommandsAggregator (42 grants total), adding a Keeper role and Guardian-callable governance setters on top of the existing permission set. Per-asset configs are seeded in step 13: 23 assets with isBoundedPricingEnabled = false (DBO returns (spot, spot) → no behavioural change), TRX with isBoundedPricingEnabled = true (live protection active).

Actions

This VIP performs the following 13 actions on BNB Chain:

  1. ACMCommandsAggregator: push permission batch — load the 42 grants for the Keeper role and Guardian-callable governance setters.
  2. Grant aggregator DEFAULT_ADMIN_ROLE on the AccessControlManager so it can execute the grants in step 3.
  3. Execute the batched permission grants via ACMCommandsAggregator.
  4. Revoke DEFAULT_ADMIN_ROLE from the aggregator after execution.
  5. Upgrade Unitroller implementation to the new Diamond-based implementation (0x82cA18785BBbacBeD1C4f482921E2B2E989D8C08).
  6. Set the new Unitroller implementation on the Comptroller proxy.
  7. diamondCut — apply the facet cut from vips/vip-665/utils/cut-params-bscmainnet.json.
  8. Wire new ComptrollerLens (0x75A71Ad878f6f24616A2AE21d046C0C8E72f67F8) on the Comptroller.
  9. Upgrade VAIController implementation to 0x8A7d8589A597619A7842d3BC284b9a5a276FaE56.
  10. Set the new VAIController implementation on the VAIUnitroller.
  11. Accept ownership of the deployed DeviationBoundedOracle (0xc79Cb7efEBd121DC4B39eA141C214606595D665A) by calling acceptOwnership().
  12. Wire DBO into Comptroller — set the DBO address as the borrow-path price source.
  13. Seed per-asset configs via setTokenConfigs on DBO with 24 entries from vips/vip-665/utils/asset-configs-bscmainnet.json — 23 with isBoundedPricingEnabled = false, TRX with isBoundedPricingEnabled = true.
