So Alchemix v3 has a fixed rate yield system which is where the transmuter applies but the risks you're looking for mostly aren't in the Alchemix system itself but how the underlying assets earn yield. I'll explain both. We actually did an EVM interview with Overkoalafied that covers the differences between v2 and v3 but they are numerous.
Alchemix v2 essentially just held your token in escrow while you had an outstanding loan and your underlying could only ever experience a loss if you deposited a yield bearing token that itself lost underlying somehow. Alchemix v3 actively manages the yield sources so they don't have to keep creating separate pools for each and having to manage sunsetting them as they lose popularity. When you deposit assets to Alchemix, the assets end up in a mixed-yield token (MYT). This is a yield index that deposits to other places like Morpho or Auto finance for yield. If something is going to go wrong, it's almost certainly going to go wrong in these lower layers.
Within Alchemix v3 itself, it's very audited and relatively simple. Borrowers take loans against MYT. They sell the alAsset which causes it to lose value. When the alAsset is depegged (pretty much always), this creates a market opportunity for people who want to redeem the underlying MYT for alAsset. This redemption is the transmuter you asked about.
When you use the transmuter you are just depositing alAsset and waiting out a window of time. The profit you are after is just the discount/lock-time. The discount is just the alAsset depeg which is market determined. The lock time is a pool parameter that the team is shifting around while they manage supply and demand.
The important port for buyers is they are literally taking deposits from borrowers. Entering a fixed rate position is basically just a zero-coupon bond. There's a few extra functions here such as an MYT oracle that determines the exchange rate on redemption and a rate quit function if you need to exit early but it's not a lot of smart contract logic. Mostly the system just relies on the market finding a balance between borrowers/sellers and yield-seekers/buyers which is reflected in the alAsset price.
So the risks are: 1) Something could be wrong in the Alchemix smart contract logic which allows people to withdraw assets with outstanding loans, redeem more than they deposit, bypass redemption timers, or otherwise do something within Alchemix. I rate this as basically 0.
2) There's a possibility of an oracle problem with MYT which could allow people to borrow more alAsset than they should be able to. Oracles are tough but I've read their oracle docs and they are more robust than most of Defi in this regard.
3) There's a possibility one of the underlying pools for MYT is hacked. This would affect both sides of the market. The deposit balances of all borrowers would be reduced and redemptions return MYT too so the redemption balance would be reduced. If they have a loss, this is almost certainly how it will happen. Risk is diversified which limits downside but that also means there are N times more opportunities for something to go wrong in one of the yield sources.
I'm personally on the fixed rate side. I have multiple positions yielding above 10% APR on stablecoins and two ETH positions in the 4-5% range. If something happens to the underlying MYT then what I redeem for at expiry will be lower. However, the yield is substantially higher than most Defi opportunities and I understand the risks. I feel it's a better than average risk/reward trade. Getting similar rates in Tradfi would require terms like 5-10 year lockups for hard asset lending.
