    permission: felt252,
    user: ContractAddress,
    contract: ContractAddress
) -> bool

Checks if a user has a specific permission.

Parameter	Type	Description
`permission`	`felt252`	Permission to check
`user`	`ContractAddress`	User address
`contract`	`ContractAddress`	Contract to check permission for

Returns: Whether the user has the permission

Session Keys

Session keys provide temporary limited permissions for specific functions.

Session Key Structure

struct SessionKey {
    public_key: felt252,
    expiry: u64,
    permitted_calls: Array<PermittedCall>
}
 
struct PermittedCall {
    to: ContractAddress,
    selector: felt252,
    calldata_len_range: (u32, u32)
}

Methods

Validate Session Transaction

fn validate_session_transaction(
    session_key_id: felt252,
    calls: Array<Call>,
    signature: Array<felt252>
) -> bool

Validates a transaction signed with a session key.

Parameter	Type	Description
`session_key_id`	`felt252`	ID of the session key
`calls`	`Array<Call>`	Calls to validate
`signature`	`Array<felt252>`	Signature to verify

Returns: Whether the transaction is valid

Policy Enforcement

Policy enforcement implements business rules and constraints for tokens and accounts.

Policy Types

Policy	Description
`TransferPolicy`	Controls when and how tokens can be transferred
`RedemptionPolicy`	Rules for redeeming tokens
`IssuancePolicy`	Rules for issuing tokens
`ExpiryPolicy`	Handles token expiration rules

Methods

Check Transfer Policy

fn check_transfer_policy(
    token: ContractAddress,
    from: ContractAddress,
    to: ContractAddress,
    amount: u256
) -> bool

Checks if a transfer complies with the policy.

Parameter	Type	Description
`token`	`ContractAddress`	Token contract address
`from`	`ContractAddress`	Sender address
`to`	`ContractAddress`	Recipient address
`amount`	`u256`	Amount to transfer
