Policy Engine

The Policy Engine is what makes Stash credit configurable. Rather than one-size-fits-all credit, every credit line is governed by a policy that defines exactly who can use it, what they can do with it, and under what conditions.

The tighter the constraints, the less collateral is needed — because the protocol's downside risk is bounded. This is how Stash can offer favourable or even undercollateralised credit terms: not because the risk disappears, but because it is constrained.

Components

Credit Operators

Credit operators enable Stash users to grant access to their Stash credit line to other users or agents. Furthermore it allows to define fine-grained policy on the credit access provided such as:

• Actions — which Stash actions such as draw, repay and withdraw collateral are allowed
• Amount caps — per-transaction and per-period limits
• Co-sign requirements — actions above a value threshold require an additional approval

Guardrailed Credit Accounts

Stash supports the creation of guardrailed credit accounts that grant Stash permissions on the issued funds.
