# Sub coins

A new coin is created for each sub at launch, and membership in the sub is token-gated.

* 1 billion total fixed supply for each sub coin
* 10,000 sub coins required for membership

### At launch

* A coin is created for the sub with a total fixed supply of 1 billion coins.
* 10M sub coins are sent to the sub creator.
* 20% of the coin supply is sent to the sub's Rewards Pool (200M coins).
* 490M coins are deployed in a Meteora DBC pool as single-sided liquidity with a starting price of 0.000000015 SOL per coin (\~$0.000002).
* After the pool is deployed, anyone can trade sub coins and the price steadily increases with buys.

### Graduation

* When the market cap reaches \~$30,000 in the bonding curve, the coin [graduates](https://docs.subs.fun/core-features/graduation).
* 75 SOL from the bonding curve is migrated and paired against the remaining 300M sub coins in a Meteora Dynamic AMM V2; a constant product pool that supports price discovery up to infinity.
* This liquidity position is locked forever, guaranteeing that there will always be a tradable market.
* 20% of the trading fees generated by the liquidity position are added to the sub's Rewards Pool to be distributed to members based on their contributions (see [Rewards](https://docs.subs.fun/core-features/rewards)).

### Trading

* Sub coins are instantly discoverable by aggregators both pre and post-graduation.
* You can buy and sell any amount of sub coins through the Subs app and DEX aggregators.
* Trades made through the Subs app incur a 1% platform fee.

### Membership

* When you own at least 10,000 sub coins, you are granted membership to the sub.
* Members are awarded sub coins for posting good content from the sub's [Reward Pool](https://docs.subs.fun/core-features/rewards). This incentivizes high quality, relevant content that the subagent can learn from, creating value.

## Why do subs need coins?

Subs have coins so members of online communities can be rewarded for the value they create by posting high-quality content, engaging meaningfully, or simply being early to a topic.

Use cases (to be launched):

* Sub coins can be burned to start a private chat with the subagent
* Revenue generated by the subagent (e.g. paid newsletter) can be directed back to coin holders
* Sub coins can be tipped to the subagent or between users
* Sub coins can be used to vote on sub governance and subagent functionality
* Sub coins can be burned to host AMAs, giveaways, or rent banner space
