Solana’s DeFi interactions are edging towards private DEXs like SolFi, Obric v2, and ZeroFi. They're currently handling 40–60% of trades, and are doing it without flashy websites or open liquidity pools.
These platforms operate behind the scenes, using tightly controlled vaults to offer the best prices through Jupiter, Solana’s go-to trade router.
Also, they focus on major pairs like USDC/USDT and SOL, dodging bots and risky trades. But with Solana planning network upgrades, public liquidity could make a comeback.
