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