Coinbase publishes Q1 Solana validator report: Staked 40.48 million SOL and advances multi-client architecture

Coinbase has published its Q1 2026 Solana validator report, disclosing its staking scale, infrastructure upgrades, and network optimization progress. The report reveals that Coinbase has staked approximately 40.48 million SOL on the Solana network, accounting for 9.52% of the total staked supply on the network.

The report also notes that Coinbase has implemented a near-zero-downtime (ZDD) upgrade mechanism. By utilizing hot-swapping and dual-signature protection, it ensures that validator updates do not affect network security and stability. Coinbase supports multi-client systems including Harmonic, Jito, JitoBAM, Firedancer, and Rakurai to enhance the diversity and resilience of the Solana validator ecosystem, while avoiding the risks associated with a single scheduling strategy.
