[Multi-Chain] Deprecated and Off-boarded Markets — Step 2 of 2 & Oracle Feed Update

1. Deprecated and Off-boarded Markets — Step 2 of 2

This proposal is the second and final step of the two-step wind-down of deprecated and previously off-boarded markets across BNB Chain, opBNB, Optimism, Unichain, Ethereum, Base, Arbitrum, and zkSync Era. Step 1 (Deprecated and Off-boarded Markets — Parameter Update (Step 1 of 2)) made these markets non-economical to borrow and closed outstanding parameter gaps. Step 2 sets the liquidation threshold to 0 on every market covered by Step 1 — the collateral factors are already 0 — at which point any position still using these assets as collateral becomes eligible for liquidation.

Summary

If approved, this VIP will:

  • Set the liquidation threshold to 0 on all markets covered by Step 1, completing the two-step wind-down begun in VIP-634 / VIP-635. The full market list is unchanged from Step 1 and is available in the Step 1 Community Post.
  • Update the main price feed for 15 markets on Ethereum, Arbitrum, and BNB Chain (see below).

Note: one market — PT-sUSDE-JUN2025 — was inadvertently omitted from Step 1. On review, it was already off-boarded in June last year and has been delisted for about a year, so it is included here to complete the wind-down. The market currently holds only two positions, together worth less than $1.

2. Oracle Price Feed Update

Bundled with this proposal, each asset’s main price oracle is repointed to a new feed via the ResilientOracle. On BNB Chain, BNB and WBNB share the same feed.
