TrustfulRiskModule

This is an implementation of the RiskModule that relays fully on trusted accounts to price and resolve the policies.

Roles

The specific functions of the contract are as follows:

Role	Global*	Description	Methods Accessible
PRICER_ROLE		Creates new policies.	newPolicy: Creates a new policy. newPolicyFull: Creates a new policy with all its details and returns the created policy data.
RESOLVER_ROLE		Resolves policies.	resolvePolicy: Resolves a policy by executing the necessary actions within the contract. resolvePolicyFullPayout: Resolves a policy with full payout.

( * ) 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.

External Methods

newPolicy

function newPolicy(uint256 payout, uint256 premium, uint256 lossProb, uint40 expiration, address onBehalfOf, uint96 internalId) external returns (uint256)

Creates a new Policy

Requirements:

• The caller has been granted componentRole(PRICER_ROLE)

Emits:

• {PolicyPool.NewPolicy}

Name	Type	Description
payout	uint256	The exposure (maximum payout) of the policy
premium	uint256	The premium that will be paid by the policyHolder
lossProb	uint256	The probability of having to pay the maximum payout (wad)
expiration	uint40	The expiration of the policy (timestamp)
onBehalfOf	address	The policy holder
internalId	uint96	An id that's unique within this module and it will be used to identify the policy

Name	Type	Description
[0]	uint256	Returns the id of the created policy

resolvePolicy

function resolvePolicy(struct Policy.PolicyData policy, uint256 payout) external

Resolves a policy, if payout > 0, it pays to the policy holder.

Requirements:

• The caller has been granted componentRole(RESOLVER_ROLE)

• payout <= policy.payout

• block.timestamp >= policy.expiration

Emits:

• {PolicyPool.PolicyResolved}

Name	Type	Description
policy	struct Policy.PolicyData	The policy previously created (from {NewPolicy} event)
payout	uint256	The payout to transfer to the policy holder

resolvePolicyFullPayout

function resolvePolicyFullPayout(struct Policy.PolicyData policy, bool customerWon) external

Resolves a policy with full payout (policy.payout) if customerWon == true

Requirements:

• The caller has been granted componentRole(RESOLVER_ROLE)

• block.timestamp >= policy.expiration

Emits:

• {PolicyPool.PolicyResolved}

Name	Type	Description
policy	struct Policy.PolicyData	The policy previously created (from {NewPolicy} event)
customerWon	bool	If true, policy.payout is transferred to the policy holder. If false, the policy is resolved without payout and can't be longer claimed.
