Base Fee
Web3 / crypto economics
The base fee is a mandatory component of transaction costs on Ethereum, introduced by the EIP-1559 upgrade in August 2021. It represents the minimum price per unit of gas required to include a transaction in a block, and it is algorithmically adjusted based on network congestion. Unlike traditional gas prices determined purely by supply and demand, the base fee creates a more predictable fee market. Crucially, the base fee is burned (permanently removed from circulation) rather than going to miners or validators, which reduces Ethereum's overall token supply and can create deflationary pressure. Example: During the Ethereum Shanghai upgrade period in April 2023, the base fee fluctuated between 20-100 gwei depending on network activity, while users could add priority tips to expedite their transactions beyond the protocol's baseline requirement. Why it matters for crypto economics: The base fee mechanism improves fee predictability for users and introduces a supply-side economic lever that affects token circulation. By burning fees rather than distributing them, it directly influences Ethereum's monetary policy and long-term scarcity dynamics.
