# SAFU Introduction

SAFU is the first protocol in financial history to introduce **self-repaying insurance**, leveraging the synergy of restaking primitives and yield-bearing tokens to create a safer version of any asset. As a **Yield Distribution Protocol**, SAFU functions as on-chain insurance, providing decentralized fallback protection for yield-bearing assets in the event of insolvency, failure, or any other.

**The Untapped Opportunity in DeFi Insurance**

The global insurance market is a [multi-trillion-dollar ](https://www.statista.com/markets/414/topic/461/insurance/)industry in traditional finance, with well-defined use cases and proven profitability. In contrast, DeFi’s insurance sector remains vastly underdeveloped, with inefficiencies in pricing, limited scalability, and a lack of mature infrastructure.

**The Role of Restaking and Yield Composability**

Restaking, a $30 billion industry at the time of writing, promises higher returns in exchange for increased risk. However, the actual real yields of most AVSs (Active Validated Services) are close to 0, as total value locked (TVL) increases without proportional real revenue growth (excluding token emissions).

Simultaneously, the growth of DeFi money legos and yield composability has surged, with the total size of yield-bearing tokens—such as stablecoins, liquid representation tokens (LRTs), and liquid staking tokens (LSTs)—expanding at an unprecedented rate. This trend highlights the immense potential of building scalable financial solutions atop these assets. Protocols like [Balancer](https://medium.com/balancer-protocol/balancer-v3-the-future-of-amm-innovation-f8f856040122) or [Pendle](https://beincrypto-com.webpkgcache.com/doc/-/s/beincrypto.com/pendle-finance-defi-growth/) are building exclusively leveraging the potential of Yield Bearing Tokens.

**Bridging Economic Value and Security**

By integrating with restaking platforms and harnessing yield-bearing tokens, SAFU bridges the gap between restaking’s vast economic value, DeFi’s dynamic composability, and the need for efficient, scalable insurance solutions. 

SAFU aims to deliver **fairly priced, scalable insurance markets** that redefine how risk is managed in DeFi.
