We’re excited to announce a new partnership between Spire and BTCS, focused on improving Ethereum block building through higher quality inclusion and more efficient transaction delivery. This collaboration integrates Spire’s DA Builder into BTCS’s Builder+ operations, aligning transaction aggregation with robust block building infrastructure on Ethereum. BTCS Inc. is a publicly traded blockchain company focused on Ethereum, building and operating scalable, revenue-generating infrastructure across the Ethereum network. Anchored by expertise in block building, validator operations, and decentralized finance, BTCS supports growth within the Ethereum ecosystem through consistent execution and long-term focus. This new integration with Spire creates a tighter path from transaction execution to Ethereum settlement. For BTCS, it expands and diversifies order flow while strengthening its Builder+ operations.Improving transaction delivery on EthereumAs Ethereum evolves, with account abstraction, smart wallets, and increasingly complex application flows, reliable and cost efficient transaction delivery has become essential. Spire’s DA Builder is designed to meet this need by optimizing how transactions reach Ethereum blocks. DA Builder aggregates transactions to:Reduce gas costs at scaleEnsure fast and reliable inclusionImprove execution qualityDeliver MEV protectionDA Builder is already used by leading relayers, wallet providers, and L2 networks, reflecting growing adoption across the Ethereum ecosystem.Building Ethereum infrastructure togetherThis partnership reflects a shared belief that Ethereum infrastructure works best when aggregation, execution, and block building are designed together. By combining Spire’s DA Builder with BTCS’s block building expertise, we’re advancing more efficient and predictable transaction delivery on Ethereum. We look forward to working closely together to expand this integration and strengthen Ethereum’s transaction and block building pipeline. Together with BTCS, we’re helping shape the future of how applications execute and settle on Ethereum.
