About

In the decentralized economy, timing is financial strategy. Network fees (Gas) fluctuate wildly based on global demand, moving from cents to hundreds of dollars in minutes. This tool is engineered for high-volume traders, DeFi users, and casual holders who demand precision. It replaces guesswork with algorithmic cost prediction.

We solve the "Blind Sign" problem: users approving transactions without understanding the fiat impact or alternative network options. By aggregating real-time data from Layer-1 (Bitcoin, Ethereum) and scaling solutions (Arbitrum, Polygon, Optimism), we provide a comprehensive landscape of block space liquidity. Use this to optimize your entry points, avoid overpaying during congestion spikes, and discover cheaper execution paths.

Formulas

Cost estimation requires normalizing distinct fee markets into a unified fiat value. For EVM chains (Ethereum, L2s), we utilize the EIP-1559 fee model.

Cost_fiat ≈ {

GasLimit × (BaseFee + PriorityFee) × Price_tokenSize_vB × Rate_sat/vB × Price_BTC × 10⁻⁸

Where GasLimit represents the computational complexity (e.g., 21,000 for ETH transfer, 180,000 for Swap). Layer 2 costs include an additional L1 Data Availability scalar: Fee_L2 = Execution + L1_Call_Data.

Frequently Asked Questions

This is our comparative analytics engine. If you calculate the cost of a "Swap" on Ethereum Mainnet ($15.00), the tool simultaneously checks Layer-2 networks (like Arbitrum or Optimism) to show you that the exact same transaction might cost only $0.15 there. This empowers you to route your capital efficiently.

The Priority Fee (or 'Miner Tip') is the bribe you pay to block producers to process your transaction faster. During "Red" traffic light periods, standard fees get ignored. Our "High/Fast" estimate includes a dynamic buffer (typically +10-20%) to ensure near-instant inclusion.

Yes. Following the Dencun upgrade (EIP-4844), Layer 2 networks use "blobs" for cheaper data storage. Our algorithms account for the reduced L1 data posting costs, which is why you see significantly lower fees for Arbitrum, Base, and Optimism compared to legacy models.

If you used a "Low" fee setting during a traffic spike, your transaction is in the mempool. You have two options: 1) Wait (risky, could take days), or 2) Perform a "Speed Up" (Replace-By-Fee) in your wallet. Use the "Fast" rate shown in this tool as your new gas price to unstick it immediately.

We aggregate price feeds from multiple oracles. However, crypto volatility is high. The fiat value is a snapshot at the moment of calculation. For large transactions, always leave a buffer of at least 10-15% in your wallet to cover sudden price slips.
