SignedQuoteRiskModule
This is an implementation of the RiskModule that relays fully on trusted accounts to price and resolve the policies. The pricing of the policy is done off-chain and provided as a cryptographically signed quote. This signature has to be later provided by the user creating the policy.
Roles
The specific roles and functions of the contract are as follows:
( * ) Global means that the role can be delegated to a user at the protocol level (for all components) or only for a specific component. Non-global roles can only be granted for a specific component.
Note on risk module roles
The PRICER_ROLE is normally granted to a Service EOA (i.e., an account used by a service as opposed to a human user) that produces signed quotes for a risk partner. Given that these are services exposed to the internet, they may require regular or emergency private key rotation for security reasons.
Usually, the role admin for the PRICER_ROLE is globally changed from the DEFAULT_ADMIN_ROLE to a specific PRICER_ROLE_ADMIN role that's granted to an operational Multisig with no timelocks, or to a timelock with a lower delay.
The same applies to the role admin for RESOLVER_ROLE and POLICY_CREATOR_ROL.
