# Problem - Solution

### The Problem

#### 1. Idle Bitcoin

More than **$1 trillion** worth of BTC sits in wallets earning 0 % yield. For long-term holders, the only way to unlock liquidity today is to **sell** or **wrap** their coins—both break Bitcoin’s native security guarantees.

#### 2. Risky Work-arounds

Ethereum-style lending apps (e.g., Aave) let you borrow against BTC only after it is converted into *Wrapped BTC (WBTC)* and moved across a **cross-chain bridge**. Bridges have been the single biggest point of failure in crypto security, with **$2 billion lost to bridge hacks in 2022 alone**.

#### 3. Institutional Friction

Regulated funds and treasuries cannot justify bridge or wrapping risk, nor can they tolerate opaque risk models. As a result, most BTC capital remains sidelined—an untapped pool that limits Bitcoin’s role in modern finance.

### How It Works (Plain English)

1. **Deposit BTC**\
   Send Bitcoin to a Helios vault address secured by a decentralized validator network.
2. **Smart-Contract Logic Executes**\
   The smart contract reads your deposit and updates the lending pool instantly—no token wrapping required.
3. **Borrow or Earn Yield**
   * **Lenders** accrue yield in BTC every block.
   * **Borrowers** draw liquidity in stablecoins or BTC, backed by their collateral.
4. **Risk Managed in Real Time**\
   The protocol continually adjusts collateral requirements using on-chain price feeds and mempool data, keeping lenders safe without manual intervention.
