IPolicyRegistry.isAuthorized

Generated B20 reference for isAuthorized(uint64,address).

Signature

function isAuthorized(uint64 policyId, address account) external view returns (bool);

Field	Value
Selector	0x55a1179e
Canonical signature	isAuthorized(uint64,address)

Description

Returns whether account is authorized under policyId. Never reverts.

The evaluation logic depends on the policy type:

isAuthorized(policyId, account):
    if policy is ALLOWLIST:
        return account is in the policy

    if policy is BLOCKLIST:
        return account is not in the policy

    if policy is UNION:
        for each child policy:
            if isAuthorized(child, account):
                return true
        return false

    if policy is INTERSECT:
        for each child policy:
            if not isAuthorized(child, account):
                return false
        return true

For composite policies (UNION and INTERSECT), evaluation is live — each call reads the current membership of every evaluated child. Short-circuiting applies: UNION stops at the first authorizing child, and INTERSECT stops at the first non-authorizing child. Child order can therefore affect gas cost but never the authorization result.

Unknown or never-created policy IDs collapse to empty-member-set semantics:

• ALLOWLIST → false
• BLOCKLIST → true
• UNION with no children → false
• INTERSECT with no children → true

A never-created INTERSECT ID returns true for every account, behaving like ALWAYS_ALLOW. Callers that store policy IDs MUST call policyExists(policyId) before storing them.

Parameters

Name	Type	Description
policyId	uint64	Policy to query.
account	address	Account to check.

Returns

Type	Description
bool	true if account is authorized under policyId, false otherwise.

Access control

Read-only. No caller restrictions.

Policy interaction

This is part of the singleton PolicyRegistry surface used by B20 policy scopes. A composite policy ID is passed to a B20 policy slot exactly like a simple policy ID; B20 stores policy IDs as an opaque uint64 and calls isAuthorized generically.

Example

bool ok = StdPrecompiles.POLICY_REGISTRY.isAuthorized(policyId, account);
