answers 402

Shared risk exposure across declared positions: pass ?positions=aave:200000,morpho:150000 and get, per factor, how much capital sits behind the same collateral, oracle or curator, and via which venues. Morpho is attributed per isolated market, Compound by its real posted-collateral basket; Aave is unattributed because a v3 supplier is exposed to the whole pool, never split across assets. Verified
