Free Monad & Web3 Tools
A growing suite of free, no-signup tools for Monad and EVM builders — unit and hex converters, a Keccak-256 hasher, address checksums, a gas fee calculator, and token-launch helpers. Everything runs in your browser.
Monmint's free tools are browser-based calculators and converters for building on Monad and other EVM chains — convert wei, gwei, and ether, decode hex and timestamps, hash with Keccak-256, validate addresses, estimate gas, and plan a token launch. No signup, no cost, and they run entirely client-side.
Token launch
- Tokenomics & FDV CalculatorPlan a token's supply allocation and see its fully-diluted valuation — split supply across team, liquidity, and community buckets.
- Vesting Schedule GeneratorModel a TGE unlock, cliff, and linear vesting — see exactly how many tokens unlock each month.
- Launch Price CalculatorWork out your token's starting price, liquidity value, and FDV from the tokens and MON you add to the pool.
- Token Burn CalculatorSee how burning a number of tokens changes total supply — the new supply and the percentage removed.
Converters & dev utilities
- Wei · Gwei · Ether ConverterConvert between every Ethereum and Monad denomination — wei, gwei, and ether — with exact, big-integer precision.
- Hex ⇄ Decimal ConverterConvert hexadecimal and decimal integers in both directions — exact for full uint256 values from calldata and block payloads.
- Unix Timestamp ConverterConvert a Unix timestamp to a human date and back — in seconds (on-chain block.timestamp) or milliseconds.
- Keccak-256 HasherHash any string with Keccak-256 and get the 4-byte function selector and 32-byte event topic the EVM uses.
- Address Checksum ValidatorValidate an address and convert it to its EIP-55 checksummed form to catch typos before you send.
- Gas Fee CalculatorEstimate a transaction's fee from its gas limit and gas price — in MON and USD, with a live price.
DeFi & trading
- Impermanent Loss CalculatorSee how much a liquidity position loses versus holding when the paired assets' prices diverge.
- Crypto Profit CalculatorCalculate profit, ROI, and return multiple from your entry and exit prices, including trading fees.
