Requests
Any request, read as a shape.
Send anything to the info, exchange or explorer endpoint, on mainnet or testnet, from presets like outcomeMeta and settleOutcome or by hand. The response comes back shaped rather than raw.

studio.hip4.devThe protocol surface, callable.
A browser playground for Hyperliquid's protocol surface - requests, precompiles, CoreWriter, validators and signing - for builders, with no backend.

- Request, precompiles, CoreWriter, validators, signing
- Precompile source
- Hyperliquid's L1Read.sol
HyperEVM
Precompiles and CoreWriter, decoded both ways.
Every HyperCore read precompile is a typed form built from Hyperliquid's own L1Read.sol. The live CoreWriter stream is decoded by action id, and an encoder builds calldata without sending it.
Signing lab
Why the exchange thinks you are someone else.
The signing page lays out msgpack bytes, action hash, EIP-712 payload and signer recovery for L1 actions. No backend - every call goes out from the browser you opened it in.
