Radial is a Solana DEX with a star topology where every token pairs only with SOL, and cross-token swaps execute as a 2-hop through SOL via virtual netting — a pure ledger update, no physical capital movement. Its core innovation: 73–99% of each hub's SOL is deployed to internal native staking, with only a small on-chain buffer sized by a deterministic worst-case bound on single-slot demand.
