hyper-evm-lib

hyper-evm-lib

The all-in-one developer toolkit for building and testing smart contracts on HyperEVM.

Key Features

CoreWriterLib and PrecompileLib

Libraries to simplify the process of writing EVM contracts which interact with HyperCore

These securely abstract away the low-level mechanics of Hyperliquid's EVM ↔ Core interactions so developers can focus on building your protocol's core business logic.

HyperCore foundry simulation

A robust testing framework to simulate HyperCore interactions (bridging, precompile-reads, and CoreWriter actions) in foundry tests.

This enables developers to seamlessly test their contract's HyperCore interactions -- all locally in a foundry test environment, in seconds -- instead of spending hours in testnet.
