Free DeFi Tools
Interactive calculators and comparators built for DeFi users. No signup required, no data collected, runs entirely in your browser. Use these tools to make better decisions about providing liquidity, staking, bridging, and managing risk in DeFi.
Impermanent Loss Calculator
Calculate IL for any liquidity pool. Compare LP returns vs holding, factor in fees, and visualize across price ranges.
Open tool ->Staking Rewards Calculator
Estimate staking rewards for ETH, SOL, ATOM and more. Compare validators and protocols.
Open tool ->Gas Fee Estimator
Estimate transaction costs across Ethereum, L2s, and alt-L1s. Find the cheapest chain for your transaction.

Open tool ->Why We Build These
DeFi is powerful but complex. Most tools are buried inside protocol apps or locked behind paywalls. We build free, standalone tools that help you understand the math before you commit capital. Every calculator uses the real formulas from the actual smart contracts - no black boxes.
