Tools for HyperEVM

Every tool below works on HyperEVM and every other EVM chain — read any HyperEVM contract, decode HyperEVM calldata before signing, or convert wei to HYPE with exact math. All client-side — keys and payloads never upload.

EVM Contract Reader

Call view functions on any HyperEVM contract via your own RPC

EVM Calldata Decoder

Decode HyperEVM transaction input — function and arguments, before you sign

Transaction Decoder

Break out a signed HyperEVM transaction: sender, gas, fees, calldata

ABI Encoder & Decoder

Encode calldata for HyperEVM contract interactions

Function Selector Calculator

Compute 4-byte selectors for function signatures

EVM Unit Converter

Convert wei, gwei, and HYPE with BigInt-exact math

Vanity Address Generator

Generate custom addresses — same key works on HyperEVM and every EVM chain

Address Checksum (EIP-55)

Validate and checksum HyperEVM addresses to catch typos

CREATE2 Address Calculator

Derive deterministic contract addresses before deploying to HyperEVM

EIP-1967 Proxy Slot Checker

Read implementation and admin slots of HyperEVM proxies

Storage Slot Calculator

Compute Solidity storage slots for HyperEVM contract state probes

Uniswap Math Calculator

v2/v3/v4 pool math — amounts out, ticks, sqrtPrice

Uniswap v4 Hook Calculator

Map hook addresses to their permission flags

Keccak-256 Hasher

Hash with the exact algorithm used by the EVM

Multi-Chain Wallet Generator

Generate keys and HyperEVM addresses from one mnemonic

ENS Namehash Calculator

Derive EIP-137 namehash values for ENS names

Solidity to Opcodes

Compile Solidity and inspect the EVM assembly
