web3.gas-calldata-compression Calculator
Calculates calldata compression savings and gas reduction from compressed transaction data for gas fee estimation for blockchain transactions on L2 rollups. Calldata costs 4 gas/byte (zero bytes) or 16 gas/byte (non-zero) — L2 compresses calldata with zlib/zstd before posting to L1, reducing calldata costs 3–5×.
Inputs
Calldata Bytes
Reference formula or conversion factor shown for context.
Zero Bytes Pct
Reference formula or conversion factor shown for context.
Eth Price
Current USD price of 1 ETH. Used to convert gas fees from ETH to dollars. Highly volatile.
Gwei
Price per unit of blockchain computation (gwei). Higher gas price = faster confirmation. 1 gwei = 10⁻⁹ ETH.
Results
calldata gas cost
The total monetary cost computed for the given inputs.
cost (USD)
The total monetary cost computed for the given inputs.
cost (ETH)
The total monetary cost computed for the given inputs.
total bytes
The combined total across all inputs and components.
