Hyperliquid adds optional wallet allowlists for builder-run perps
The testnet-only HIP-3* framework lets market deployers proxy actions that are limited to reduce-only trades and can cancel specific resting orders.
Hyperliquid is introducing an optional testnet extension, HIP-3*, that lets independent builders create perpetual markets with venue-specific wallet allowlists, according to a Sept. 3 developer update covered by CryptoSlate.
HIP-3* is designed to be strictly additive, so existing Hyperliquid markets remain unchanged. The API reference says a new venue can be designated HIP-3* when created, enabling an onchain allowlist and proxied user actions within that venue boundary.
The specification lists five operator powers available to a HIP-3* deployer, or to approved sub-deployers they delegate to. Those actions include adding or removing allowlist approvals, canceling specified resting orders, bulk canceling resting orders and time-weighted average price orders on the venue, placing reduce-only orders, and moving collateral to another account on the same venue.
CryptoSlate notes the proxy mechanism is constrained so it can only reduce a position, not increase one, and it does not act like a protocol-wide wallet freeze or a regulatory check. Hyperliquid described HIP-3* as access control and operator powers for a newly created venue, with no announced mainnet date since the extension is currently testnet-only.
