Validator vote to delist FXS

Validators will vote on whether to delist FXS around 7:30 UTC on 6 January. FXS is being rebranded to FRAX. This permissionless stake-based vote weighting primitive is built natively into HyperCore and technically requires no offchain coordination. If validators vote to delist an asset, the perps will settle to the 1 hour time weighted spot oracle price before delisting, and open orders will be canceled. Close any positions beforehand to avoid automatic settlement. After settlement, no new orders will be accepted.
