Permissionless

A system that anyone can interact with without seeking approval, creating an account, or meeting eligibility criteria — just a compatible wallet and the required assets. Permissionless is a core DeFi property: anyone on earth with a crypto wallet can supply to Aave, trade on Uniswap, or stake on Lido without identity verification or approval. This contrasts with permissioned systems where participants must be whitelisted or approved.
