EIP-1559 · interactive mechanism simulation

Wallets submit typed transactions with a max fee and a tip. Each block's protocol-computed base fee is burned; the tip goes to the proposer; the base fee then adjusts by at most the capped step for the next block. Edit the parameters and watch the fee market respond.

Illustrative simulation. Base fee, gas-used ratio, and adjustment math follow EIP-1559's real formula (target = gas limit ÷ 2, capped ±12.5% step by default), but demand, transaction sizes, and timing are simplified and randomized for visualization — not live onchain data. Drag the sliders to explore how the fee market responds. Part of The Onchain Experiment Atlas.
