BTCS Recognizes ETHGas Mainnet Launch and Its Priority Builder Role on ETHGas

Silver Spring, Maryland--(Newsfile Corp. - June 18, 2025) - BTCS Inc. (NASDAQ: BTCS) ("BTCS" or the "Company"), a leader in blockchain infrastructure and technology, is proud to recognize the mainnet launch of ETHGas, a low-latency Ethereum infrastructure protocol designed to unlock real-time transaction execution. BTCS is currently the only live Priority Builder on the ETHGas network-a position that underscores BTCS's growing role in helping scale Ethereum and drive scalable revenue growth.

BTCS's participation in the ETHGas mainnet launch aligns with our ongoing strategy to expand market share and deliver scalable revenue growth by advancing core infrastructure across the Ethereum ecosystem. Over the last month, blocks built by BTCS are estimated to have included approximately 2.4% of all transactions on Ethereum-demonstrating our infrastructure's critical role in supporting the network.

"We're pleased to see ETHGas officially live on mainnet and to be actively participating as the sole live priority builder at launch," said Charles Allen, CEO of BTCS. "This first mover advantage positions us to drive scalable revenue growth by increasing orderflow and blockspace and helping ETHGas redefine how blockspace is accessed and monetized."

The ETHGas mainnet introduces sub-3 millisecond block pre-confirmations--up to 100x faster than Solana--and enables deterministic access to blockspace by allowing validators to pre-sell block slots. As a priority builder, BTCS is uniquely positioned to maximize early-stage exposure, optimize block construction economics, and contribute to a more efficient Ethereum.

"BTCS's active role for the ETHGas mainnet launch signals the growing demand for reliable, high-performance builders," said Kevin Lepsoe, Founder of ETHGas. "We're excited to collaborate with BTCS as we institutionalize Ethereum's gas markets and bring real-time execution and predictable blockspace to the forefront of Ethereum scalability."
