According to the source, ETHGas raised $12 million in a seed round led by Polychain Capital to develop a real-time Ethereum blockspace trading platform targeting 50-millisecond block times, source: public X post dated Dec 19, 2025. For context, Ethereum’s current slot time is 12 seconds, implying the stated target is roughly 240 times faster, source: Ethereum.org documentation on slots and epochs. Lower block times reduce per-block latency available for arbitrage and MEV, which tends to compress time-sensitive spreads and alter orderflow dynamics, source: Daian et al., Flash Boys 2.0 and Ethereum.org resources on MEV and proposer–builder separation. Traders can monitor forthcoming technical milestones, testnet performance, and any integrations with builders or relays as potential catalysts for ETH liquidity and MEV strategy returns, source: Ethereum.org proposer–builder separation overview and Flashbots research literature.
