DeFi Development Corp. (DFDV) has begun integrating Harmonic’s open block‑building marketplace into its Solana validator operations, allowing the company to select from multiple block candidates each slot. The move is designed to increase revenue capture and enhance decentralization of the Solana network by giving DFDV greater control over which block it publishes.
Harmonic aggregates block candidates from a network of independent builders, enabling validators to choose the most valuable block for each slot. By doing so, DFDV can capture a larger share of MEV and transaction‑fee revenue. Management expects measurable improvements in staking rewards and fee income in the coming weeks as the platform goes live.
DFDV’s long‑term goal of 1.0 SOL per share by 2028 is a key performance metric for the company. Improving validator efficiency through Harmonic’s platform accelerates progress toward that target, potentially increasing investor exposure to Solana’s growth prospects and strengthening DFDV’s competitive position against other public companies that stake SOL.
The integration follows a strong Q3 2025 earnings season, during which DFDV reported robust performance and raised $125 million in equity to fund its Solana treasury strategy. The move represents a major operational milestone that could materially affect future revenue streams and the company’s ability to meet its SOL‑per‑share objectives.
DFDV competes with other public companies that stake SOL, such as the Solana Foundation and other validator operators. Harmonic’s open marketplace introduces competition and choice into block production, potentially reducing concentration of block control and increasing network decentralization, which benefits all validators in the ecosystem.
While specific financial targets for the integration are not disclosed, DFDV’s management emphasized that the platform will enhance revenue capture and validator performance. The upgrade positions the company to better meet its SOL‑per‑share goals and strengthen its competitive stance within the Solana ecosystem.
