unprobed
Crypto categories & sectors ranked by total value locked (USD): each DeFi narrative (e.g. Dexes, Lending, Liquid Staking, Restaking, RWA) with its aggregate TVL, protocol count and share of total DeFi TVL. A map of where capital sits across sectors. Centralised-exchange reserves are excluded.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
