# IDO Rules

<figure><img src="/files/aSZou5vqNxNQEnR16kyp" alt=""><figcaption></figcaption></figure>

**The BSCS IDO Rule System** is crafted to safeguard investors while optimizing their experience through three distinct rules:

**💎** [**Riskless**](/defi-1/ido-rules/riskless.md) **IDO Rule:** Offers a simple, all-or-nothing refund mechanism for all participants.

**💎** [**Vanguard**](/defi-1/ido-rules/vanguard.md) **IDO Rule:** Provides flexible refund options, including partial refunds, for strategic flexibility.

{% hint style="info" %}
We will apply the specific IDO rule depending on each IDO project status.

These rules leverage a unified [Tier System](/defi-1/tier-system-and-allocation.md), where higher tiers (Unicorn and Decacorn) unlock extended refund windows and exclusive perks.
