Security & Trust

DeFiLlama Swap is non‑custodial: funds remain under user control until settlement. The protocol uses audited smart contracts, rate‑limiters on relayers, and multi‑party settlement to reduce front‑running and MEV risks. For high‑value transfers, users can enable guarded mode (hardware wallet + extended confirmation).
