# Referral Program
Every player is a gateway. Invite codes are the only way in.
Cash City is **permanently invite-only**. There is no public signup, no open registration, and no way to bypass the invite system. Every new player enters through someone else's invite code — and the person who shared that code earns rewards.
***
## How It Works
Every player in Cash City has a unique invite code visible in their profile. Share it anywhere — X, Discord, DMs, group chats — and when someone uses your code to enter the game, you're linked as their Referrer.
### Multi-Tier Rewards
Cash City uses a two-tier Referral system:
| Tier | Relationship | Reward |
| ------ | ----------------------------------------- | ---------------------------- |
| Tier 1 | Direct invite (you → them) | 5% of all $CASH they claim |
| Tier 2 | Their invites (you → them → someone else) | 2.5% of all $CASH they claim |
When someone you invited brings in another player, you earn a second-tier reward from that downstream player's activity as well. This creates a compounding incentive to invite active players who will themselves invite others.

## Maximising Your Referral Earnings
Your Referral code is most valuable when it reaches people who will be **active, long-term players** — not one-time visitors.
* **Share on X with context.** Don't just post your code. Show your earnings, your Intern collection, or your Firm setup. Give people a reason to want in.
* **Target crypto communities.** Players who already have Solana wallets and understand on-chain gaming will convert at a much higher rate.
* **Build a network.** Your Tier 2 earnings mean the best Referral is someone who will also actively invite others. Inviting one crypto influencer can be worth more than inviting 100 casual players.

## Viewing Your Referrals
Your referral dashboard in the Office shows your total invites, active referred players, and accumulated referral rewards across both tiers.
