SBTs Transform Web3 Beyond Memes: Reputation Becomes Revenue Stream
**Soulbound Tokens (SBTs)** are emerging as Web3's answer to moving beyond speculation and memes. These non-transferable NFTs represent identity, achievements, and credentials - but Envelop's upgradable version makes them dynamic.
**Key Applications:**
- **Gaming**: Players buy ERC-20 "power" or "armor" tokens to upgrade NFT assets, creating new revenue streams
- **Reputation Systems**: Drop reputation tokens into SBTs for completed quests or contributions, leveling from "Junior" to "Legend"
- **Event Access**: Fan badges that brighten with attendance, providing tokenized loyalty rewards
Unlike static credentials, these **upgradable SBTs** can be enhanced with ERC-20 tokens, making them living representations of user progress. In DAOs, they track actual contributions across skills like development and marketing.
The model enables **free NFT launches** with monetized skill sales, combining user growth with revenue generation through transparent, provable achievements.
