# CUBEs (Credentials)

### CUBEs Overview

CUBEs are onchain credentials that users mint to complete an Activation and claim the rewards.

Each CUBE is a unique ERC-721 NFT (EVM) and Compressed NFT (Solana) that records data onchain including:

* Information about the Activation and Community
* Proof of activation actions (e.g. transaction hashes)
* When the Activation was completed

CUBEs mean that with every Activation completed, users build their on-chain profiles, the Layer3 identity protocol gets more valuable, and creators can measure distribution success.

69M+ CUBEs have been minted by 3.3M+ users on 50+ EVM chains plus Solana to-date.

### Understanding CUBEs for Activation Creators

Users are required to mint the CUBE credential in order to verify the Activation completion onchain and claim the rewards.

As an Activation Creator CUBEs enable you to:

1. **Build & Own Your Onchain Audience:** Get real-time, onchain data on exactly who completed your Activations. Every CUBE mint represents a verified user who took your desired action.
2. **Power Targeted Campaigns & Retention:** Use your CUBE holder list to:
   * **Allowlist** users for token sales, NFT drops, or exclusive features.
   * **Target** them with follow-up Activations to deepen engagement (e.g., “Complete Activation 2 if you finished Activation 1”).
   * **Reward loyalty** by creating new campaigns exclusively for users who hold specific CUBEs.
3. **Segment High-Value Users:** Analyze which users are completing multiple Activations or high-difficulty tasks. These are your power users—target them for ambassador programs or premium experiences.
4. **Cross-Promote & Collaborate:** Target users who completed *other* relevant Activations (e.g., users who completed a Uniswap Activation) to acquire users already interested in similar protocols.
5. **Measure True Distribution Success:** Your CUBE mint data is your key performance indicator (KPI). Track metrics like total unique mints, completion rate, and user overlap to understand your campaign’s reach and effectiveness.

**In short: CUBEs are your onchain CRM. They transform one-off campaign participants into a valuable, reusable audience you can continuously engage and grow.**

**Remember - you can gate community experiences by your CUBE holders**
