[Hyperliquid Announces Testnet HIP-4 for Binary Markets Included in Mainnet-Level Bug Bounty Program] BlockBeats News, April 3: Hyperliquid officially announced that the testnet result trading for binary markets has now been immediately included in the mainnet-level bug bounty program. The current bug bounty scope does not include multi-result markets. Front-end feedback is welcome but is not eligible for rewards under the bug bounty program. Previously reported, Hyperliquid announced that HyperCore would support result trading (HIP-4). It is reported that results are fully collateralized contracts with settlement prices confined within a fixed range. This is a general-purpose foundational trading component applicable to scenarios such as prediction markets and bounded options tools.
