# IDO Pools

TinyBlock IDOs are split into two main pools to balance fair access and exclusive opportunities for all participants: Guaranteed Pool & FCFS Pool (First come, first served).

**Allocation & Join Rules**

* Allocation sizes (min/max per user) are set by each project.
* If a pool is oversubscribed, the system will automatically recalculate final allocations and users can claim back the remaining funds.
* Join timeline varies per pool and project - sometimes sequential, sometimes simultaneous.
