Crypto token analytics and on-chain data tools
Cover live prices, gas fees, multi-chain wallets, address checks, unit converters, and developer utilities. Private keys and seed phrases are computed locally in your browser for verification and research.

Wallet tools
Bulk Wallet Generator
Bulk Wallet Generator derives multi-chain addresses and private keys in your local browser for ETH, BTC, Solana and TRX. Seed phrase or keys; CSV export.
Vanity Address Generator
Vanity Address Generator searches locally for EVM addresses with a custom hex prefix or suffix on ETH, BSC, Arbitrum. Multi-threaded; keys stay on-device.
Address QR Code
Wallet Address QR Code turns an EVM receive address into a PNG in your local browser. Plain or EIP-681, EIP-55 checksum, custom size; nothing uploaded.
Chain data
Gas Tracker
Gas Tracker reads live gas via read-only RPC on Ethereum, BNB Chain, Base, Arbitrum and Polygon. Slow, standard and fast tiers with USD transfer estimates.
Bulk Balance Checker
Bulk Balance Checker queries native and ERC-20 balances for up to 50 addresses on ETH, BSC, Solana and TRX via read-only RPC. Format checks; CSV export.
Converters
ETH Unit Converter
ETH Unit Converter converts Wei, Gwei and Ether with exact integer math in your local browser. For gas quotes, uint256 checks and 18-decimal EVM amounts.
BTC Unit Converter
BTC Unit Converter converts BTC, mBTC, bits and satoshis with exact integer math and a live USD reference. For transfers, sat/vB fees and Lightning checks.
Token Decimals Converter
Token Decimals Converter converts ERC-20 human amounts to raw on-chain integers and hex by decimals. Presets for 18, 8 and 6; exact integer math locally.
Calculators
Gas Fee Calculator
Gas Fee Calculator estimates EVM fees from gas used and Gwei on Ethereum, BNB Chain, Base and Polygon, with USD at live rates. Transfer and swap presets.
Profit Calculator
Crypto Profit Calculator estimates spot P&L from buy price, sell price, invested amount and fee rate: coins, proceeds, net profit, ROI and break-even.
Impermanent Loss Calculator
Impermanent Loss Calculator estimates Uniswap V2 50/50 constant-product IL from two token price moves versus holding. Fee income excluded; not for V3.
Developer tools
Hex Converter
Hex Converter converts hex to UTF-8 text and decimal big integers, plus Keccak256 and function selectors. For input data and logs; local browser only.
ABI Encoder & Decoder
ABI Encoder Decoder builds calldata from a function signature and JSON args, or decodes input data into readable parameters. Runs in your local browser.
Contract Address Calculator
Contract Address Calculator predicts EVM deploy addresses via CREATE (deployer, nonce) or CREATE2 (factory, salt, init code). For ETH, BSC, Base and more.
Hash Calculator
Hash Calculator computes Keccak-256, SHA3-256, SHA-256, SHA-512, RIPEMD-160 and Bitcoin Hash160 from text or hex locally. Distinguishes Keccak from SHA3.
Base64 / Base58
Base64 Base58 Encoder Decoder converts text and hex across Base64, Base58 and Base58Check with checksum checks. For BTC, WIF and Solana; runs locally.
Timestamp Converter
Unix Timestamp Converter converts second or millisecond stamps to local time, UTC and ISO 8601, and back. Live clock for block times, unlocks and API data.
Security
Password Generator
Password Generator creates strong random passwords with crypto.getRandomValues in your local browser. Set length, character sets and entropy; not uploaded.
Address Checksum
Address Checksum validates EVM length, charset and EIP-55 checksum in bulk, then converts to checksum form. Up to 1,000 addresses; catch typos early.
Signature Verifier
Signature Verifier recovers the signer from an Ethereum personal_sign (EIP-191) message and 65-byte signature, then checks an expected address. Local only.
