+# TGrade Trusted Circle Payments
+
+This contract makes regular payments to the Oversight Community and Arbiter Pool members.
+
+## Init
+
+To create it, you must pass the Trusted Circle and the Arbiter pool contract addresses.
+As well as an optional `admin`, if you wish it to be mutable.
+
+```rust
+pub struct InstantiateMsg {
+  /// Admin (if set) can change the payment amount and period
+  pub admin: Option<String>,
+  /// Trusted Circle / OC contract address
+  pub oc_addr: String,
+  /// Arbiter pool contract address
+  pub ap_addr: String,
+  /// The required payment amount, in the payments denom
+  pub denom: String,
+  /// The required payment amount, in the TC denom
+  pub payment_amount: u128,
+  /// Payment period
+  pub payment_period: Period,
+}
+
+pub enum Period {
+  Daily,
+  Monthly,
+  Yearly
+}
+```
+
+## Messages
+
+#### Notes
+  - This contract is to be funded from block rewards, i.e. its address and distribution percentage must be in the `distribution_contracts` tgrade_valset list.
+  - If there are not enough funds to make a `payment_amount` to all OC + AP members, the existing funds are distributed to the engagement point holders.
+  - Funds are distributed directly to members through `Bank::Send`. This assumes the total number of members is small (less than thirty).
+  - If both OC and AP addresses are of the same contract, they are treated as different addresses, i.e. each member will be paid "twice".
+  - The contract would need an `EndBlocker` privilege, to check the payment time, and execute it if appropriate.
+    Alternatively, a cron contract could call the payment entry point with a frequency greater or equal than that of `payment_period`.
