SolVoid brings programmable, account-level privacy to Solana. Unlike mixers or private wallets that only hide transactions, SolVoid hides account ownership, balance logic, and behavioral patterns while remaining fully composable with existing Solana programs. Built using stateless, compressed account design, it avoids heavy zk provers and isolated pools, delivering low fees, high performance, and production-ready privacy as core infrastructure, not a bolt-on feature.
