HIP-4 research

HyperCore L1 · community doc
Full markdown reference

Official 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.

Unofficial documentation

Hyperliquid has published no HIP-4 spec; this site is reverse-engineered from bytecode, txs, and HyperCore API — not official content.

Testnet & two tracks
  • 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.

Bridge L1↔EVM
Architecture, CoreWriter, precompiles, asset indices
