DeFi Derivatives & Perpetuals

Spot trading swaps one asset for another, here and now. Derivatives are contracts whose value is derived from something else — a price, a rate, an index — and they let you take a position far larger than your cash, bet on direction without owning the asset, and hedge risk you already hold. In traditional finance, derivatives notional dwarfs the spot market. On-chain, the same gravity took hold, and one instrument ran away with the crowd: the perpetual future.

This course builds the on-chain derivatives machine from the ground up:

• What a perpetual future is — a futures contract with no expiry date, and the puzzle that creates: with nothing forcing settlement, what keeps its price glued to spot?
• The funding-rate mechanism — the elegant answer: a periodic payment between longs and shorts that makes holding the “wrong” side expensive, dragging the perp back to the index every few hours.
• Leverage & liquidation engines — how a small margin controls a large position, the exact liquidation price that follows, and the keeper bots and engines that close you out before your loss turns into the protocol’s loss.
• Insurance funds & ADL — the backstops for when liquidation isn’t fast enough: a shared insurance fund absorbs bad debt, and auto-deleveraging socializes the rest to the most-profitable traders on the other side.
• Perp-DEX designs — the three architectures that answer “where does the price come from?”: on-chain order books, virtual AMMs (vAMMs), and oracle/pool-based designs, each with its own decentralization-vs-oracle-risk trade-off.
• On-chain options & power perps — convex payoffs on-chain, and the exotic “everlasting” instruments (power perpetuals) that package gamma without an expiry.
• Basis trades & cash-and-carry — how the funding premium that powers the whole system becomes a market-neutral yield: long spot, short the perp, harvest the carry.

This sits at the top of the ladder, where the DeFi branch meets the derivatives branch. It assumes you already know how an AMM walks a constant-product curve, how a classic future and its basis work, and what an option’s payoff and the Greeks mean. By the end, a “perp” stops being a casino chip and becomes a precise, fundable, hedgeable instrument you can price, risk-manage, and arbitrage.
