EVM Tools

Polygon PoS Developer Tools

High-throughput sidechain with its own validator set. Polygon uses the same EVM instruction set and address format — every tool here works out of the box.

Tools for Polygon PoS

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

EVM Contract Reader

Call view functions on any Polygon PoS contract via your own RPC

EVM Calldata Decoder

Decode Polygon PoS transaction input — function and arguments, before you sign

Transaction Decoder

Break out a signed Polygon PoS transaction: sender, gas, fees, calldata

ABI Encoder & Decoder

Encode calldata for Polygon PoS contract interactions

Function Selector Calculator

Compute 4-byte selectors for function signatures

EVM Unit Converter

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

Vanity Address Generator

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

Address Checksum (EIP-55)

Validate and checksum Polygon PoS addresses to catch typos

CREATE2 Address Calculator

Derive deterministic contract addresses before deploying to Polygon PoS

EIP-1967 Proxy Slot Checker

Read implementation and admin slots of Polygon PoS proxies

Storage Slot Calculator

Compute Solidity storage slots for Polygon PoS 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 Polygon PoS 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
