# Risk Defined & Protected Yield Aggregator

Perhaps the simplest instantiation, an **Instrument** can represent any yield-generating strategy in DeFi, where the instrument contract can be as simple as supplying to the relevant DeFi protocol. 

Passive LPs would by default be exposed to a senior tranche to a wide set of complex strategies assessed by the managers in a single click. They would however are also able to granularly customize their risk profiles for each individual instrument.

RAMM could be a one-stop area for all complex yield sources out on the risk curve, powered by a decentralized risk assessment and insurance tech. 

LPs would be able to gain

1. set and forget yield for a number of complex strategies
2. higher yields
3. insurance
4. strategies assessed by key Defi opinion leaders whose incentives are forcibly aligned with LPs via code

with a single click, and 

5. the ability to customize risk exposures for each instrument if desired

Simple Example

A RAMM USDC vault invests in the following strategies, approved by the managers. 

1. Strategy 1, yielding 10% APR 
2. Strategy 2, yielding 13% APR
3. Strategy 3, yielding 8% APR

For managers who participate in each instrument, their `longZCB` APR is as follows(rough number, specific would depend on individual vault parameters) 

1. Strategy 1, junior tranche yielding 20 % APR
2. Strategy 2, junior tranche yielding 21% APR
3. Strategy 3, junior tranche yielding 13% APR

Note that a manager need not buy into every instrument `longZCB.` 

For LPs who invest in this RAMM USDC vault, their APR is as follows 

1. Strategy 1, senior tranche yielding 7% APR
2. Strategy 2, senior tranche yielding 8% APR
3. Strategy 3, senior tranche yielding 5 % APR

Yielding an average of 6.66% for the vault. However, an LP could also customize his instrument exposures. For an LP who is especially bullish on strategy 1 but bearish on strategy 3, he can create a custom vault as the following

1. Strategy 1, senior tranche yielding 20 % APR
2. Strategy 2, senior tranche yielding 8% APR
3. Strategy 3, senior tranche yielding 0% APR
