DeFi Development Corp. Partners with Harmonic to Optimize Solana Validator Revenue and Network Participation
BOCA RATON, FL, Dec. 01, 2025 (GLOBE NEWSWIRE) -- DeFi Development Corp. (Nasdaq: DFDV) (the “Company”), the first public company with a treasury strategy built to accumulate and compound Solana (“SOL”), today announced it has begun integrating and running the open block-building infrastructure provided by Harmonic across its Solana validator operations.
Harmonic introduces competition and choice into Solana’s block-building pipeline. Instead of relying on a single builder, validators can select from multiple block candidates each slot. This improves revenue potential, strengthens decentralization, and gives operators more control over the types of order flow they accept.
For DFDV, integrating Harmonic provides three clear benefits:
- Higher validator revenue: Harmonic allows DFDV to automatically choose the most valuable block each slot, improving staking and validator efficiency.
- Greater transparency and control: DFDV can set builder preferences that align with its standards as a public company.
- Enhanced network contribution: Participating in a multi-builder system diversifies block production and helps strengthen Solana’s resilience, which directly supports long-term SOL accumulation and SOL-per-Share growth.
The company has already integrated Harmonic into its validator stack and expects to see measurable improvements in validator performance and revenue capture in the coming weeks. The Company will monitor results and provide updates through future investor communications.
