web3.gas-l2-settlement Calculator
Calculates L2-to-L1 settlement cost, batch size optimisation, and finality time for gas fee estimation for blockchain transactions on rollup networks. Optimistic rollup settlements have a 7-day fraud proof window — zkEVM rollups achieve faster L1 finality (minutes) by submitting validity proofs instead.
Inputs
Tx Count
Reference formula or conversion factor shown for context.
Batch Size
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
settlement cost
The total monetary cost computed for the given inputs.
cost per tx
The total monetary cost computed for the given inputs.
batches needed
The value at the specified point or condition.
total gas
The combined total across all inputs and components.
