ETHGas, a developer focused on Ethereum blockspace infrastructure, has raised $12 million in a funding round led by Polychain Capital. Other participants in the round include Stake Capital, BlueYard Capital, SIG DT, and Amber Group. The investment aims to transform blockspace into a programmable financial market, enabling instant, invisible, and budgetable transactions. In addition to the funding, ETHGas has launched Ethereum's blockspace market, securing $800 million in commitments from validators and builders. The introduction of funding rates is expected to significantly influence the dynamics of this emerging market.
