Functions

Creator Functions

Function	Description
registerCreator(uint96 price)	Register with monthly USDC price
updatePrice(uint96 newPrice)	Change price (doesn't affect existing subs)
deactivateCreator()	Stop accepting new subscriptions
reactivateCreator()	Resume accepting new subscriptions

Subscriber Functions

Function	Description
subscribe(address creator, uint8 months)	New subscription (reverts if already active)
renew(address creator, uint8 months)	Extend existing/expired subscription

View Functions

Function	Returns
isActive(address creator, address user)	bool
getExpiration(address creator, address user)	uint256 (timestamp)
creators(address)	(uint96 price, bool active)

Owner Functions

Function	Description
pause() / unpause()	Emergency shutdown
setPlatformFeeRecipient(address)	Change fee wallet
setPlatformFeeBps(uint16)	Change fee % (max 10%)
transferOwnership(address)	Initiate ownership transfer
acceptOwnership()	New owner accepts

Events

event CreatorRegistered(address indexed creator, uint96 pricePerMonth);
event PriceUpdated(address indexed creator, uint96 newPrice);
event Subscribed(
    address indexed creator, address indexed subscriber,
    uint256 expiresAt, uint8 months,
    uint256 totalAmount, uint256 creatorPayout, uint256 platformFee
);
event Renewed(
    address indexed creator, address indexed subscriber,
    uint256 expiresAt, uint8 months,
    uint256 totalAmount, uint256 creatorPayout, uint256 platformFee
);
event CreatorDeactivated(address indexed creator);
event CreatorReactivated(address indexed creator);

Fee Structure

Subscriber pays $10
  --> $9.50 (95%) to creator
  --> $0.50 (5%)  to platform

• Fee is set in basis points (500 = 5%)

• Hard cap at 1000 (10%) — owner cannot set higher

• Fee recipient: 0x1E3C58204B930643F8845AAC7B9C5145d01062a7

Security

• Zero-address validation in constructor

• subscribe() reverts if already active (protects remaining time)

• Two-step ownership transfer

• Pausable for emergencies

• Fee hard cap at 10%

• SafeERC20 for USDC transfers

• Non-upgradeable (immutable code)
