Omnipool: delist BNC (Asset 1 of 6)

This referendum executes the first delisting from the discussion post "Omnipool liquidity strategy: reducing exposure to underperforming assets, cutting liquidity costs, and preparing for concentrated liquidity" (https://hydration.subsquare.io/posts/264).

Based on the performance review in that post, six assets are set for removal from the Omnipool: BNC, ASTR, vASTR, SUI, vDOT and KSM. BNC is first on the list; subsequent referenda will propose the removal of the remaining five, one asset per referendum, so each can be judged and tracked on its own.

What this referendum does

On enactment, BNC trading in the Omnipool is set to remove-liquidity-only. Over the following ~27 blocks (about 3 minutes), all BNC farm positions are exited with rewards paid out, and every BNC liquidity position (215 positions) is returned in full to its owner — roughly 2.0M BNC (~$29k) back to LPs. LPs do not need to do anything: BNC is credited to wallets automatically. The BNC token is then removed from the Omnipool, and the protocol-owned share of the liquidity — roughly 3.8M BNC (~$54k) — is returned to the Treasury.

This referendum also stops the two remaining Bifrost-funded Omnipool farms (vDOT and vASTR) in preparation for the upcoming vDOT and vASTR delisting referenda. Existing farm positions are not touched and accrued rewards remain claimable — stopping only prevents new entries.

Verification

The full call was executed end-to-end on a fork of mainnet: BNC removed from the Omnipool, all 215 positions and all farm deposits returned to their owners, protocol liquidity returned to the Treasury, and both Bifrost farms confirmed stopped.
