HIP-4 documentation
Testnet · Exploratory documentation — not official Hyperliquid documentation.
HIP-4 research
HyperCore L1 · community docOfficial HIP-4 flow is native HyperCore: market creation, CLOB trading, and VoteGlobalAction settlement.
HyperEVM parimutuel contracts (V1/V2) are documented separately as third-party / unconfirmed — use the Third-party EVM group in the sidebar.
Hyperliquid has published no HIP-4 spec; this site is reverse-engineered from bytecode, txs, and HyperCore API — not official content.
- Testnet only. Chain 998 for HyperEVM examples — mainnet addresses are not validated here.
- HyperCore L1 = confirmed prediction flow. HyperEVM (V1/V2) = separate third-party parimutuel docs — see sidebar labels.
Research & HyperCore
Narrative, native lifecycle, API shapes, and market context — start with any item below.
What to open first
- Timeline — how the research unfolded (X archive).
- HyperCore (L1) — architecture, lifecycle, pair minting.
- Trading fees (L1) — spot-like fees,
SetOutcomeFeeScale, fill normalization. - Info endpoint — full
POST /info+ WS blocks (GitBook-style). - API & data — one-page tables (URLs, wallets, S3).
- Industry compare — HIP-4 vs Polymarket vs Kalshi.
L1 ↔ HyperEVM
How HyperCore and the embedded EVM relate: EvmRawTx, bridge mechanics, precompiles.
Third-party EVM (unconfirmed)
V1 from bytecode · V2 aligned with Solidity in repo. Not the official L1 settlement path.
