# Supply & Circulation

How $SPIN reaches circulation from a fixed supply: scheduled releases from the Player Rewards pool, offset by the weekly buyback.

The total supply of $SPIN is fixed at 1,000,000,000. The contract has no mint function after the token generation event, so no new tokens are ever created. What changes over time is not the total supply but how much of it is in circulation.

Tokens reach the community from the Player Rewards & Airdrops allocation, 125,000,000 $SPIN or 12.5% of supply, which is set aside at launch and released on a published schedule. Release categories include:

* Player rewards
* Seasonal competitions
* Staking incentives
* Ecosystem growth grants

The release schedule is designed to decline over time, so the rate at which tokens enter circulation slows as the platform matures and the weekly buyback takes over as the engine.

Working in the other direction, the buyback permanently removes tokens from circulation every week. See [Buyback & Burn](/spin-token/buyback-and-burn.md) for how that works, and [Vesting](/spin-token/vesting.md) for the full unlock timeline.
