DeFi allows for the possibility of crypto losses through self-custody errors. While “not your keys, not your coins” means your crypto can be safely stored on your personal crypto wallet(s), the flip side of this is “lose your keys, lose your coins.” If you don’t have recovery measures in place (a secondary wallet backup or a recovery phrase) and you lose your wallet or forget its access password, you will lose all the crypto stored on the wallet.
