-# ENS Bulk Registration
+# Grails Contracts
 
-A smart contract for batch-registering ENS `.eth` names in a single transaction. Targets the current wrapped [ETHRegistrarController](https://etherscan.io/address/0x253553366Da8546fC250F225fe3d25d0C782303b) and supports mixed-length names (3, 4, 5+ chars) with different prices.
+Solidity contracts for [Grails](https://grails.wtf): batch ENS `.eth` name registration and Grails PRO subscriptions. Built with [Foundry](https://book.getfoundry.sh/).
 
 ## Features
 
+### Bulk Registration
 - **Batch registration** — register multiple `.eth` names in one transaction
 - **Mixed-length support** — no same-price restriction; each name is priced individually
 - **Referral tracking** — emits `NameRegistered` events with an immutable referrer
 - **Automatic refunds** — excess ETH is returned in the same transaction
 - **Batch utilities** — bulk availability checks, price quotes, commitment generation
 
+### Subscriptions
+- **Pay-per-day subscription** — subscribe to Grails PRO for any number of days
+- **Extend active subscriptions** — additional days stack on current expiry
+- **Owner-controlled pricing** — contract owner can update the daily rate
+- **Owner withdrawal** — owner can withdraw collected funds
+- **Ownable2Step** — safe two-step ownership transfers
+

+
+## Bulk Registration Flow
 
 1. **Check availability** — call `available(names)` to verify names are open
 2. **Get pricing** — call `totalPrice(names, duration)` for the required ETH
 3. **Commit** — call `makeCommitments(...)` then `multiCommit(commitments)`
 4. **Wait** — wait at least 60 seconds for the commitment to mature
 5. **Register** — call `multiRegister{value: totalPrice}(...)` with sufficient ETH; excess is refunded automatically
+
+## Subscription Flow
+
+1. **Check price** — read `pricePerDay()` for the current daily rate
+2. **Subscribe** — call `subscribe{value: pricePerDay * days}(durationDays)`
+3. **Check status** — call `getSubscription(address)` to view expiry timestamp
+4. **Extend** — call `subscribe()` again; additional days extend from current expiry if still active
