Ethereum co-founder Vitalik Buterin has suggested a trustless, onchain futures market for gas to bring greater predictability to Ethereum transaction costs. Key Takeaways: Vitalik Buterin proposes a trustless onchain gas futures market to let users lock in future Ethereum transaction fees. The system would function like traditional futures markets, helping traders and developers hedge against sudden fee spikes. Buterin says a futures market could bring predictable costs for heavy network users. In a post on X over the weekend, Buterin said repeated questions about whether Ethereum’s roadmap can guarantee low fees inspired him to outline how such a market could work. Buterin Says Onchain Gas Futures Could Let Users Lock In Ethereum Fees Buterin argued that an onchain gas futures system would give users the ability to lock in gas prices for future time windows, offering greater certainty as Ethereum scales. The concept mirrors traditional futures markets, such as those for commodities, where buyers and sellers agree on a fixed price for a future date to hedge risk or speculate on price movements. Applied to Ethereum, it would allow users to prepay for a specific amount of gas during a chosen time period, protecting them from unexpected fee spikes. “People would get a clear signal of expectations for future gas fees, and would even be able to hedge against future gas prices,” Buterin wrote. He suggested that a market-built signal for future base fees could help traders, developers, and heavy network users plan with far more confidence, especially those managing large volumes of transactions or operating decentralized applications. We need a good trustless onchain gas futures market. (Like, a prediction market on the BASEFEE) I've heard people ask: "today fees are low, but what about in 2 years? You say they'll stay low because of increasing gaslimit from BAL + ePBS + later ZK-EVM, but do I believe you?"… — vitalik.eth (@VitalikButerin) December 6, 2025 Gas costs have eased this year, with basic Ethereum transfers averaging around 0.474 gwei, roughly one cent, according to Etherscan. However, more complex activity still comes at a higher cost, including token swaps ($0.16), NFT transactions ($0.27), and cross-chain bridging ($0.05). Despite the overall decline, fee volatility remains a challenge. YCharts data shows average Ethereum fees started 2025 near $1 before falling to $0.30, punctuated by swings as high as $2.60 and as low as $0.18. Buterin’s proposal aims to smooth these fluctuations by giving users a mechanism to anticipate and manage costs, particularly ahead of high-demand periods. Ethereum Exchange Balances Hit Record Lows As reported, Ether held on centralized exchanges has dropped to an all-time low , with balances falling to just 8.7% of total supply, the smallest share since Ethereum launched in 2015. The decline marks a 43% drop since July, a shift analysts say is tightening liquid supply and setting the stage for a potential market squeeze. The rapid drawdown is linked to structural changes in how ETH is being used. More tokens are flowing into staking, restaking protocols, layer-2 networks, DeFi collateral loops, digital-asset treasury holdings, and long-term self-custody, all destinations that rarely send ETH back to exchanges. Research outlet Milk Road said ETH is now in its “tightest supply environment ever,” noting that Bitcoin’s exchange balance remains significantly higher.
