## Reward Mechanics

* Rewards accrue automatically via a cumulative index.
* No claim transaction is required.
* Users receive XCN when calling `unstake()`.

## User Flow

1. Connect wallet on Goliath Testnet
2. Open `/#/yield`
3. Enter XCN amount and submit stake action
4. Hold stXCN while rewards accrue automatically
5. Call `unstake()` when exiting to receive XCN

## Developer Notes

* Start from the explorer-verified ABI for the stXCN proxy.
* Index-based accounting means apparent yield is reflected through conversion math, not claim loops.
* Track staking lifecycle via on-chain events plus `balanceOf`/supply state.
