Ethereum’s blockspace trading platform, ETHGas, has successfully raised $12 million in a seed funding round led by Polychain Capital. This development follows Ethereum co-founder Vitalik Buterin’s recent discussions on the potential of an onchain “gas futures” market, which could provide users with clearer fee expectations and allow them to hedge future costs.
ETHGas is advocating for a reimagined allocation of blockspace on the Ethereum network. The platform launched with substantial commitments totaling $800 million from various validators, builders, and other participants. The company aims to make blockspace a tradable commodity while significantly enhancing Ethereum’s speed through an initiative dubbed “Real-Time Ethereum.” This involves purchasable blockspace commitments, known as “pre-confirmations,” that ensure execution at specific times.
Founder Kevin Lepsoe explained that this system functions upstream of current block production services often used by maximum extractable value (MEV) bots. The approach divides blocks into 240 segments of 50 milliseconds each, resulting in almost zero MEV and a rapid Ethereum experience with effective block times of 50 milliseconds. However, Lepsoe acknowledged potential centralization risks, as ETHGas could increase validator rewards significantly, incentivizing centralization. To mitigate these risks, ETHGas plans to establish multiple nodes with a leader-election process, requiring community engagement.
ETHGas claims its system can handle over 10,000 transactions per second, with users able to define block placement. Pre-confirmations allow for whole block acquisition, top-of-block reservations, or guaranteed inclusion in a block. Execution guarantees ensure not only inclusion but also specific pricing or positioning within a block. Although execution guarantees have been tested on the mainnet, broader deployment is expected by early 2026.
Validators back the pre-confirmations and can post collateral in Ether or restaked Ether. If agreements are not honored, validators may face slashing, with collateral transferred to the buyer. To date, validators have honored 99.96% of pre-confirmations, though this claim remains unverified independently. Trust in ETHGas’s ability to manage and evaluate slashing is essential, but no issues have arisen so far.
