Gas Fee Checker

loading… · 12 NETWORKS · 60-SECOND REFRESH

Compare estimated fees in dollars and the network’s own token. Choose a transaction preset, then check the cost and observation time for each chain. A dated daily USD reference keeps the conversion consistent as gas readings refresh.

The scenario sets EVM gas, Solana compute units and Cardano size. Bitcoin and Tron have their own presets below.

Modelled fees use fixed gas, compute-unit and size presets. L2 figures cover execution; rollup data and operator fees are additional. Confirm the complete quote in your wallet.
About fees & how we estimate
  • Ethereum (L1): Base from eth_feeHistory, tip from eth_maxPriorityFeePerGas. Scenario cost = (base+tip) × gasUnits, converted to USD.
  • BNB Chain / Polygon / Avalanche C-Chain: The node’s suggested eth_gasPrice multiplied by the scenario gas preset. Gas is paid in BNB, POL and AVAX respectively. Polygon network · Avalanche network.
  • Arbitrum / Base / Optimism (L2): Execution estimate = eth_gasPrice × gas preset. A complete quote also requires transaction-specific rollup data charges and any operator fee. These execution figures cover part of the transaction cost. OP fee components.
  • Solana: One signature at 5,000 lamports plus the priority fee rounded up to whole lamports. Priority uses the 60th percentile of recent node observations and the chosen compute-unit budget. Account creation and rent deposits are additional. Solana fee formula.
  • Cardano: Minimum size-based fee = b + a·size from current Koios protocol parameters. Script execution charges and minimum output deposits are additional; swap and NFT presets are illustrative transaction sizes.
  • Robinhood Chain: Mainnet 4663 uses ETH for gas. The estimate covers execution using the selected EVM gas preset. Transaction-specific Ethereum data charges are additional. Network details.
  • Bitcoin: The selected virtual size multiplied by mempool.space’s medium-priority rate, rounded up to a whole satoshi. Actual size depends on inputs, outputs and script types; confirmation timing varies. Fee-rate guide.
  • Tron: Modelled TRX burn assumes all selected Bandwidth and Energy must be purchased at the current chain-parameter rates. The TRX-transfer preset uses 300 bytes and zero Energy. The illustrative contract preset uses 350 bytes and 65,000 Energy; actual contract usage varies. Available free, staked or delegated resources reduce the burn, potentially to zero. Account activation and multi-signature charges are additional. Resource charges.
  • USD reference: Each token’s first available daily conversion price is saved on this device for the UTC day, using CoinGecko with Coinbase as a fallback. Each quote has its own observation time and source. A missing token price affects only that token’s USD conversion. Fees refresh separately every minute while this page is open.
  • Local history: The last 60 modelled USD costs per chain are saved in this browser.

These estimates use fixed transaction presets. Wallet quotes depend on the actual transaction, network conditions and additional data or script fees. Each calculation is explained in “About fees & how we estimate” inside the checker.
