what's Solana Staking Index?

The Solana Staking Index (SSI) provides a standardized, transparent benchmark for network-wide Solana staking yields. It calculates a baseline rate by combining verifiable on-chain staking inflation rewards and validator fees from active stake, deliberately excluding MEV rewards to ensure fairness, consistency, and comparability across validators and protocols. As core infrastructure, SSI enables stakers to compare performance, protocols to benchmark yields, institutions to assess returns, and builders to develop products like fixed-rate staking and lending markets. Fully open-source and decentralized with no single-party control, it offers real-time data, historical charts, alerts, and breakdowns via solstakingindex.com, supported by leading Solana ecosystem partners.
