ETHGas has announced the establishment of a futures market for “block space” on the Ethereum 
$3,139 network, raising $12 million in a token round, along with securing about $800 million in liquidity commitments from validators and block builders. Led by Polychain Capital, the round included Stake Capital, BlueYard Capital, Lafayette Macro Advisors, SIG DT, and Amber Group. The initiative, according to founder Kevin Lepsoe, focuses on providing block space liquidity instead of direct cash investment, aiming to make gas costs predictable while boosting validator returns. The project also plans to test its “real-time Ethereum” approach, aiming for full-scale deployment by the first quarter of 2026.
Token Round and $800 Million Liquidity Commitment
ETHGas revealed that it raised $12 million in a seed round that began in July and concluded last month, structured as a token round through a Simple Agreement for Future Tokens (SAFT). While Lepsoe did not disclose the project’s valuation, he mentioned that no board or advisory positions were offered during the round. Additionally, an undisclosed pre-seed round of about $5 million was conducted mid-2024.
In parallel with the funding, Ethereum validators, block builders, and relays committed roughly $800 million in total, providing liquidity to the ETHGas marketplace as “block space” rather than cash investment. Lepsoe noted that participants aim for higher and more predictable returns in exchange for their contributions.
On the revenue model, ETHGas charges a 5% transaction fee on block space futures and plans additional fees for real-time settlement-required applications.
How Ethereum Block Space Futures Operate and Their Objectives
ETHGas designs a market where block space can be pre-purchased and sold, rather than relying solely on instantaneous auction dynamics for block production. Block space is defined as the capacity determining which transactions enter Ethereum blocks, in what order, and at what cost. Lepsoe highlighted that the system is positioned “above” the current proposer-builder separation (PBS) production line, adding to rather than altering the existing setup.
Validators in the market can sell block space up to 64 blocks ahead, about 12.8 minutes in advance. Participants engage in various commitment types like full block sales, guaranteed inclusion in specific blocks, execution guarantees at predefined prices or chain states, and consecutive multi-block packages. Lepsoe emphasized that this motivates validators to capture more MEV, boosting staker returns.
The target for users is to hedge gas costs, make prepayments for execution, and avoid gas price surges for traders, applications, and institutions. Lepsoe noted interest from traditional finance and sovereign funds in understanding and acquiring block space, with larger commitments from digital asset treasury companies also anticipated, with new disclosures planned for January. Furthermore, Ethereum’s speed could increase 100–200 times by dividing blocks into hundreds of 50–100 millisecond segments, significantly reducing MEV while enhancing AMM arbitrage revenues, targeting full deployment by the first quarter of 2026.
