On February 6th 2024, we posted [details about Starknet v0.13.1](https://community.starknet.io/t/starknet-v0-13-1-eip4844-support-more-fee-reductions-stability-quality-of-life/112951). But every cake needs cherry on top: in addition to the features outlined in the linked post, the gas cost of a Cairo step (and of every builtin) will reduced by a factor of 2! This brings a computation down to 0.0025 gas/step.

But how? In a nutshell, SHARP will soon support larger trains, leading to improved amortization of various operation costs, consequently justifying a reduction in the amount of gas charged per step/builtin. Some subtler optimizations are also chipping in, but we’ll omit details here for the sake of brevity.

At any rate, this cherry replicates the [2x reduction of v0.13.0](https://community.starknet.io/t/starknet-v0-13-0-support-for-fee-payment-in-strk-reduced-transaction-fees/109608), continuing the fee reduction effort that will be outlined in much more detail in the upcoming weeks.

Stay tuned!
