✦ Key Insight
It removes custodial and withdrawal risk from leveraged trading, and replaces it with contract risk, oracle risk and typically thinner liquidity.
✕ Common Misconceptions
Assuming self-custody removes counterparty risk entirely. If the pool taking the other side of your trade becomes insolvent, or the oracle is manipulated, your position is affected regardless of who holds the margin.
Detailed Explanation
Perpetual DEXs replicate the leveraged products of centralised venues while keeping custody with the user. Some use on-chain order books; others quote against a shared liquidity pool where providers take the other side of traders' positions. Funding rates and liquidations work much as they do on centralised venues.
In Practice
“A trader opens a leveraged position directly from a wallet, monitors the funding rate, and closes it without ever depositing into a custodial account.”
