Sanctum

Sanctum is the unified liquidity layer for Solana liquid staking. Most major Solana LSTs run on Sanctum infrastructure, including Bybit's bbSOL, Jupiter's JupSOL, DoubleZero's dzSOL, and Bonk's. With $2.5B+ in TVL it's the 4th largest protocol on Solana, and the INF and CLOUD tokens both live within its ecosystem.
