BTCS Inc.

BTCS Inc. is a U.S.-based, Nasdaq-listed blockchain technology company that generates revenue through blockchain infrastructure and decentralized finance (DeFi) activities, primarily on the Ethereum network. The company actively participates in the Ethereum ecosystem, earning digital asset-denominated revenues from its operations. BTCS focuses on providing core blockchain infrastructure services, participating in transaction validation and block construction, and engaging in decentralized finance activities. While BTCS holds significant Ethereum (ETH), it uses ETH as an operating asset to support revenue generation across its business lines rather than as a passive holder. BTCS operates through three primary business lines. First, Validator Node Operations (NodeOps) involves operating validator nodes on the Ethereum network. As a validator, BTCS performs validation, consensus-related activities (attestation), and block proposal functions, contributing to network security and block finalization. In return, BTCS earns ETH-denominated staking revenue, which includes protocol-defined rewards and execution layer transaction fees. Second, Block Building (Builder+) involves operating proprietary block builders that construct optimized transaction blocks for submission to validators. Builder+ revenues come from fees earned when BTCS-constructed blocks are successfully proposed on-chain. The company makes digital asset payments to external validators (Validator Payments) as a direct cost to secure block inclusion. Builder+ has grown in revenue contribution due to expanded private order flow integrations, enhanced infrastructure efficiency, and increased participation in Ethereum blockspace markets. Third, Decentralized Finance Operations (Imperium), launched in 2025, focuses on deploying digital assets into decentralized finance protocols as a liquidity provider and market participant.
