You’ve seen the spreads. You’ve watched the funding rates oscillate between exchanges. But every time you think you’ve spotted the perfect cash and carry trade on Aave, something goes sideways. Maybe the funding flips. Maybe the liquidation cascade hits before you can blink. Here’s the thing — most traders approach this strategy like it’s a simple round-trip ticket. It isn’t. It’s more like threading a needle while the needle’s moving. I’ve been running this playbook for three years now, and I’m about to walk you through the exact framework that separates the traders who consistently pocket the carry from those who get cleaned out when volatility strikes.
What Exactly Is Cash and Carry on Aave?
Let’s get basic definitions out of the way first. Cash and carry is an arbitrage strategy that exploits the price difference between an asset’s spot price and its futures price. You buy the asset in the spot market, simultaneously sell a futures contract at a higher price, and pocket the difference when the contract expires. In the Aave ecosystem, this typically involves depositing collateral into Aave protocols, borrowing stablecoins, and then deploying those stablecoins into futures positions. The funding rate — that periodic payment between long and short position holders — becomes your edge. Currently, funding rates across major perpetuals hover around 0.01% to 0.05% daily, which compounds into serious money if you’re running size.
But here’s the disconnect that trips up even experienced traders: Aave isn’t just one thing. You have Aave V2, Aave V3, and various market implementations across different chains. Each has its own collateral factors, liquidation thresholds, and borrowing costs. The platform data shows that Aave currently manages over $580B in cumulative trading volume across its deployments, which tells you this isn’t a niche play — it’s infrastructure. The leverage available through these protocols can reach 10x depending on your collateral configuration, which sounds attractive until you realize that liquidation rates at those levels can trigger at 12% price movements. That’s not margin for error — that’s barely a heartbeat in crypto markets.
The Setup: Building Your Position Structure
Here’s how I build these trades. First, I deposit high-quality collateral — typically ETH or WBTC — into an Aave market. Then I borrow stablecoins at the current variable rate, which has ranged from 2% to 15% depending on market conditions. Now I take those stablecoins and deploy them into a perpetual futures position that captures the funding rate premium. The goal is simple: earn more from funding payments than you pay in borrowing costs.
The math breaks down like this. If you’re paying 5% annually to borrow and earning 10% annually in funding, you’re looking at a 5% net carry. Run that across a $100,000 position and you’re pocketing $5,000 for doing basically nothing except managing your collateral ratio. But wait — funding rates aren’t static. They swing based on market sentiment, leverage usage across the ecosystem, and macro conditions. I’ve seen funding rates collapse overnight when a major rally exhausts itself and everyone rushes to close shorts simultaneously. That’s when your carry turns into a cost center real fast.
Position Sizing That Actually Works
Most traders screw this up immediately. They go max leverage because the math looks good on paper. Then a volatility spike hits and they’re scrambling to top up collateral before liquidation. Here’s my rule: never size your position so that a 15% adverse move triggers a margin call. I aim for at least 30% buffer between my entry and liquidation price. This sounds conservative, and it is, but conservatism in leverage is what keeps you in the game long enough to actually compound returns.
The historical comparison is instructive here. Back when FTX was operational, the cash and carry plays were almost too easy — funding rates regularly hit 20-30% annualized because of the retail hype machine. Traders who piled in got burned when the exchange imploded. The lesson? Sustainable carry is boring carry. If the funding rate looks too good to be true, there’s usually a reason, and that reason is often hidden risk.
The Execution Playbook
Alright, let’s get into the actual mechanics. I start by checking the funding rate differential between exchanges. My go-to approach is to compare the funding rate on Binance versus Bybit versus dYdX — each has slightly different user bases and therefore slightly different funding dynamics. When Binance shows 0.03% daily funding and Bybit shows 0.08%, there’s often an opportunity to arb that spread or simply capture the higher rate while managing the exchange risk appropriately.
Then I look at the borrowing cost on Aave V3 versus Aave V2. V3’s portal feature sometimes creates temporary rate differentials when large positions move between markets. That’s free optionality if you’re paying attention. I also monitor the Gas costs on Ethereum mainnet versus Arbitrum or Optimism — deploying across chains adds complexity but can improve net returns when Ethereum gas spikes.
Now, the actual execution. I deposit my collateral, initiate the borrow, and immediately open my futures position. Timing matters here. You want to enter the futures position as close as possible to the funding settlement period — typically every 8 hours on most perpetuals. This ensures you start earning funding from hour one rather than missing a partial period.
The monitoring phase is where most retail traders fall apart. They set it and forget it. Then funding rates move, collateral values fluctuate, and they’re caught off-guard. I check my positions at minimum twice daily, and I have alerts set for when my health factor drops below 1.5 — that’s my early warning threshold before getting anywhere near liquidation.
When to Fold and Walk Away
Not every spread is worth capturing. I’ve walked away from trades where the borrowing cost was 12% annually and funding was only 8%. The math doesn’t work, and no amount of rationalization changes that. Also, I exit when funding rates compress below my borrowing cost for more than 48 hours. Market conditions shift, and a strategy that worked last month might be a loser today. Flexibility isn’t optional — it’s survival.
87% of traders who run leverage strategies don’t have predetermined exit criteria. That’s insane. You’re basically driving blindfolded and hoping for the best. Don’t be that person.
Common Pitfalls and How to Dodge Them
The biggest mistake I see is ignoring liquidation cascades. When a major position gets liquidated, it creates selling pressure that can cascade through the market. If your collateral is in the path of that cascade, you might face liquidation even if your position was technically sound. My workaround? I avoid using assets that are highly correlated with the asset I’m shorting in my futures position. If I’m short ETH perpetuals, I might use stETH or rETH as collateral instead of plain ETH, since the lending protocol positions can sometimes provide a buffer against cascading spot selling.
Another pitfall is underestimating gas costs when moving positions or adjusting collateral. In bull markets, Ethereum gas can eat into your returns significantly. During peak congestion, a single collateral top-up might cost $50-100 in gas fees. That’s fine if you’re running a $500,000 position, but it’s devastating if you’re running $20,000. Size accordingly or move to L2s where gas is cheaper.
And here’s something most people don’t know: the timing of your collateral deposits can affect your borrowing rate. Aave’s interest rates are algorithmically set based on utilization. If you deposit during a low-utilization period, you lock in a lower borrow rate before other traders drive utilization up. It’s not a huge edge, but over time, these small edges compound. Speaking of which, that reminds me of the time I caught a 2% better borrow rate just by checking at 3 AM versus peak hours — but back to the point, timing matters more than most people realize.
Tools and Platforms Worth Using
I use a combination of DefiLlama for tracking TVL and rate comparisons, Aave’s native dashboard for position management, and a spreadsheet where I track my net carry in real-time. The key is having a single source of truth for your P&L. When you’re running multiple positions across different chains, it’s easy to lose track of your actual returns after accounting for gas, slippage, and borrowing costs.
For the futures leg, I’ve tested Binance, Bybit, OKX, and dYdX. Each has pros and cons. Binance offers the deepest liquidity but has regulatory concerns in some jurisdictions. Bybit has competitive funding rates and a solid mobile app. dYdX gives you the decentralized experience with full custody, which matters if you’re philosophically opposed to centralized exchanges. Honestly, here’s the thing — the best exchange is the one you trust and can access reliably during high-volatility periods. Don’t sacrifice reliability for a slightly better funding rate.
The Mental Game
Let me be straight with you. The technical side is the easy part. The mental side is what kills most traders. Watching your collateral value fluctuate while you hold a leveraged position is genuinely stressful. The urge to panic-close when you see red numbers is overwhelming, especially for new traders. I’ve been there. I’ve made the mistake of closing positions right before a funding payment that would have turned a losing trade into a breakeven. I’m serious. Really.
My advice? Define your thesis before you enter. Write it down. Know exactly under what conditions you’ll add, reduce, or close your position. When the market moves against you, revisit that thesis. Did the fundamentals change, or are you just feeling emotional? If fundamentals haven’t changed, holding is often the right call. If they’ve shifted, admit it and adjust. Ego is expensive in this business.
Building a Sustainable Edge
Cash and carry isn’t a get-rich-quick scheme. It’s a yield enhancement strategy that compounds slowly but steadily when executed properly. The traders who excel at this aren’t the ones with the most sophisticated tools — they’re the ones with the discipline to size correctly, monitor actively, and exit gracefully when conditions change.
If you’re running this strategy, treat it like a business. Track your returns. Analyze your drawdowns. Identify what went wrong and fix it. Over time, you’ll develop instincts that no tutorial can teach you. But you only get there if you survive long enough to learn. Protect your capital first. The returns will follow.

Frequently Asked Questions
What is the minimum capital needed to run an Aave cash and carry strategy?
I’d recommend at least $10,000 to make the math work after accounting for gas costs, trading fees, and maintaining adequate buffer collateral. Below that, transaction costs eat too much into your returns. If you’re starting smaller, consider using Arbitrum or Optimism where gas is significantly cheaper than Ethereum mainnet.
Can I run this strategy across multiple chains simultaneously?
Yes, and many experienced traders do exactly this to capture rate differentials between markets. However, it adds operational complexity. Make sure you have robust tracking systems before attempting multi-chain execution. The upside is diversification of execution risk across different protocols and networks.
What happens if funding rates go negative?
Negative funding means short position holders pay long holders. In this scenario, if you’re shorting futures, you actually earn funding while still paying your borrowing cost on Aave. This can improve your net carry significantly, but it often signals bearish market sentiment that might increase liquidation risk on your collateral.
How do I handle liquidation risk during high volatility events?
The best defense is position sizing with adequate buffer, as mentioned earlier. Additionally, you can monitor market fear indicators and proactively reduce exposure before major events like macro announcements or protocol upgrades. Some traders also use put options as cheap insurance during particularly risky periods.
Is this strategy suitable for beginners?
I’d suggest starting with paper trading or very small position sizes before committing significant capital. Understanding how Aave’s health factor works, how funding payments settle, and how to monitor positions across interfaces takes time. The learning curve isn’t steep, but the consequences of mistakes are real.
