EVM Tools
Monad Developer Tools
Monad is a high-performance L1 with parallel EVM execution — up to 10,000 TPS with 1-second block times. Same EVM compatibility, 100x throughput.

Every tool below works on Monad and every other EVM chain — read any Monad contract, decode Monad calldata before signing, or convert wei to MON with exact math. All client-side — keys and payloads never upload.
EVM Contract Reader
Call view functions on any Monad contract via your own RPC
EVM Calldata Decoder
Decode Monad transaction input — function and arguments, before you sign
Transaction Decoder
Break out a signed Monad transaction: sender, gas, fees, calldata
ABI Encoder & Decoder
Encode calldata for Monad contract interactions
Function Selector Calculator
Compute 4-byte selectors for function signatures
EVM Unit Converter
Convert wei, gwei, and MON with BigInt-exact math
Vanity Address Generator
Generate custom addresses — same key works on Monad and every EVM chain
Address Checksum (EIP-55)
Validate and checksum Monad addresses to catch typos
CREATE2 Address Calculator
Derive deterministic contract addresses before deploying to Monad
EIP-1967 Proxy Slot Checker
Read implementation and admin slots of Monad proxies
Storage Slot Calculator
Compute Solidity storage slots for Monad 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 Monad addresses from one mnemonic
ENS Namehash Calculator
Derive EIP-137 namehash values for ENS names
