Dear Crypto Natives,
I love simple tools that make everything else in the DeFi ecosystem better.
Zaps from DeFiZap are one of those tools and it’s time we did a tactic on them.
Does anyone remember how painful it was to buy something on Amazon in when it looked like this? A ten-step process only suffered by the uber geeks brave enough to submit their credit card online.
Back then one-click eCommerce was considered a major innovation! Amazon had to license a one-click patent from Apple to even attempt it.
That’s where we are today in crypto. Simple transactions are still painful. And it’ll take a thousand tiny UX innovations like Zap to get us to mainstream.
I have hope. Because as we’re leveling up…so is DeFi.
Let’s learn about Zaps.
Tactic #25: How to use a Zap
DeFiZap is a system of smart contracts—Zaps—that deploys ETH (and now other ERC20s!) across multiple DeFi protocols in one transaction. It’s the Amazon one-click of DeFi. Use Zaps to get instant access to DeFi opportunities directly from your Ethereum wallet including 💸Lending, 🦄Pooling, ⛽️Staking, and 🚀Leveraged Liquidity.
Goal: Pick a Zap based on a DeFi position you want to take
Effort: 30 minutes
ROI: Hours of time & $100s in gas for frequent DeFi users
Why use a zap?
Zaps allow you get into a DeFi position in one transaction—it’s called zapping in.
Say you have ETH and want a position in the Uniswap ETH-DAI pool. This yielded 4% over the last 90 days but you think ETH to USD price will stay flat (important due to impermanent loss) and Uniswap fees will increase yield above the Dai Savings Rate.
Well, it’s a painful process to get into that position. You need to supply half ETH and half DAI. Takes 4 transactions. 10 minutes. Ugh. Ugly as eCommmerce in the 90s.
Zap allows you to do it in one click.
Now say you zapped into the Uniswap ETH-DAI position above. You made profit, now you want out. You can zap out the same way you zapped in. One transaction. Easy.
There are dozens of Zaps now. Each Zap is a recipe for getting into and getting out of a DeFi position—in one click.
Which Zap should I pick?
This is like asking which DeFi positions should I take? It depends what you’re trying to accomplish. DeFiZap has a simple survey you can take that recommends a few based on your tolerances. I expect we’ll see Zaps integrated directly in more wallets too.
Today Zaps provide more benefit to power users—people who already know the position they’re trying to take and the risks of each protocol and want to execute it with less time, effort, and money. Almost like an automated OTC desk.
Zaps are generally practical—they don’t shotgun your capital across the 'top 10 on coinmarketcap'—they inject into DeFi protocols built on Ethereum. Easy interactions in and out of protocols can supercharge user adoption. Though users should be aware of the risks of each underlying protocol.
Flavors of Zaps
There are many flavors of Zap today and more are added all the time. We’ll focus on Unipool Zaps for this tactic.
Unipool Zaps 🦄
Unipool Zaps auto swaps half of your input into appropriate ETH/ERC20 portions required to match for the pool, effectively allowing you to start earning liquidity fees without having to go out of your way to supply both sides of the pool. This is especially useful to help liquidity providers measure their returns.
Some popular Unipool Zaps include:
⚡️sETH Unipool: Bullish on ETH
⚡️MKR Unipool: Expect ETH to MKR rate to remain flat
⚡️DAI Unipool: Expect ETH to DAI rate to remain flat
⚡️CHAI Unipool: Expect ETH to CHAI rate to remain flat
⚡️General Unipool: Pick your own ETH-Token pool
The sETH pool keeps your ETH Exposure
If you want to keep your exposure in ETH the sETH Unipool Zap allows for one-click liquidity to sETH Pool on Uniswap using just ETH. This way you remain exposed to ETH price while generating fees from people trading ETH/sETH on Uniswap Pool plus extra SNX staking rewards. (⚠️RSA note—sETH does expose you to the risks of the Synthetix platform—make sure you understand those thoroughly before proceeding)
The cDAI and CHAI provide lending interest while you earn trading fees
You probably know a bit about DAI from our recent cDAI and CHAI articles. When holding cDAI users accrue interest based on the lending rate at any given time—8.5% as of today. CHAI works the same way, less risky than cDAI and earning 8% now.
The CHAI Unipool Zap and cDAI Unipool Zap allow you to enter these respective liquidity pools with just ETH—you earn Uniswap trading fees on top of the cDAI interest rate!
Other Zaps for lending and leverage are also available. Though again, users should assess the risks of each lending and leverage protocol before using them. For example, some of the Zaps are configured to use the Fulcrum protocol which was recently attacked. (RSA—I’m looking forward to Zaps that automate insurance on these protocols!)
Here’s a quick cheatsheet on popular Zaps available and the positions they provide:
*Please note Double Bull, Moderate Bull, Lender and Leveraged Liquidity Pools are not currently available.*
Zap into the sETH Unipool
Zap into the sETH Unipool in a two steps and one transaction.
Intermediate level: Zap in via website
Go to the sETH Zap and click ⚡️ZAP IN
Select your desired input amount and confirm.
Advanced level: Zap in via ENS
You can also Zap in via ENS! Since the sETH Unipool Zap was registered with the Ethereum Name Service under sETHUnipool.DeFiZap.eth adding liquidity is as easy as sending an Ethereum transaction. (Note: make sure your gas limit is set to 1,500,000.)
(Above: adding liquidity to sETH Unipool by sendiing ETH to ENS name)
Zaps are an awesome tool to make it faster, easier, and cheaper to get into popular DeFi positions. You can zap into positions and zap out of them in one transaction.
While Zaps make it easier to enter and exit positions, it’s still up to you to assess the ROI and risks of the underlying positions you’re entering. These are powertools, not a short-cuts. Before zapping into a Unipool you need to know how Uniswap works, before zapping into sETH learn the risks of Snythetix. Don’t zap into positions without doing your due diligence. Level up first. That’s why we do the program.
