 ## Overview
 
-QuantaPool enables QRL holders to participate in Proof-of-Stake validation without running their own validator nodes. Users deposit QRL and receive stQRL, a rebasing token whose balance automatically adjusts as validators earn rewards or experience slashing.
+QuantaPool enables QRL holders to participate in Proof-of-Stake validation without running their own validator nodes. Users deposit QRL and receive stQRL, a fixed-balance token where `balanceOf()` returns stable shares and `getQRLValue()` returns the current QRL equivalent (which grows with rewards).
 
 ### Key Features
 
 - **Liquid Staking**: Receive stQRL tokens that can be transferred while underlying QRL earns rewards
-- **Rebasing Token**: Balance increases automatically as validators earn rewards (Lido-style)
-- **Slashing-Safe**: Rebasing design handles slashing events by proportionally reducing all holders' balances
+- **Fixed-Balance Token**: Share balance stays constant (tax-friendly), QRL value grows with rewards
+- **Slashing-Safe**: Fixed-balance design handles slashing by proportionally reducing all holders' QRL value
 - **Trustless Sync**: No oracle needed - rewards detected via EIP-4895 balance increases
 - **Post-Quantum Secure**: Built on QRL's Dilithium signature scheme

-## How Rebasing Works
+## How Fixed-Balance Model Works
 
 1. User deposits 100 QRL when pool has 1000 QRL and 1000 shares
-2. User receives 100 shares, balance shows 100 QRL
+2. User receives 100 shares, `balanceOf()` = 100 shares
 3. Validators earn 50 QRL rewards (pool now has 1050 QRL)
-4. User's balance = 100 × 1050 / 1000 = **105 QRL**
-5. User's shares unchanged, but balance "rebased" upward
+4. User's `balanceOf()` still = **100 shares** (unchanged, tax-friendly)
+5. User's `getQRLValue()` = 100 × 1050 / 1000 = **105 QRL**
 
 If slashing occurs (pool drops to 950 QRL):
-- User's balance = 100 × 950 / 1000 = **95 QRL**
+- User's `balanceOf()` still = **100 shares**
+- User's `getQRLValue()` = 100 × 950 / 1000 = **95 QRL**
 - Loss distributed proportionally to all holders

- *   - Externally exposes "balance" in QRL (changes with rewards/slashing)
- *   - balanceOf(user) = shares[user] * totalPooledQRL / totalShares
+ *   - balanceOf() returns raw shares (stable, tax-friendly)
+ *   - getQRLValue() returns QRL equivalent (changes with rewards/slashing)
+ *   - Exchange rate: totalPooledQRL / totalShares
  *
- * This is similar to Lido's stETH rebasing model.
+ * This is a fixed-balance model (like wstETH) rather than rebasing (like stETH).
+ * Chosen for cleaner tax implications - balance only changes on deposit/withdraw.
  *
  * Example:
  *   1. User deposits 100 QRL when pool has 1000 QRL and 1000 shares
- *   2. User receives 100 shares
+ *   2. User receives 100 shares, balanceOf() = 100
  *   3. Validators earn 50 QRL rewards (pool now has 1050 QRL)
- *   4. User's balance = 100 * 1050 / 1000 = 105 QRL
- *   5. User's shares unchanged, but balance "rebased" upward
+ *   4. User's balanceOf() still = 100 shares (unchanged)
+ *   5. User's getQRLValue() = 100 * 1050 / 1000 = 105 QRL
  *
  * If slashing occurs (pool drops to 950 QRL):
- *   - User's balance = 100 * 950 / 1000 = 95 QRL
- *   - Loss distributed proportionally to all holders
+ *   - User's balanceOf() still = 100 shares
+ *   - User's getQRLValue() = 100 * 950 / 1000 = 95 QRL

+# QuantaPool v2 Architecture
+
+## Overview
+
+QuantaPool is a decentralized liquid staking protocol for QRL Zond. Users deposit QRL and receive stQRL tokens representing their stake. The protocol uses a **fixed-balance token model** (like Lido's wstETH) where share balances remain constant and QRL value grows with rewards.

+## Core Contracts
+
+### stQRL-v2.sol - Liquid Staking Token
+
+**Fixed-balance model** where `balanceOf()` returns shares (stable) and `getQRLValue()` returns QRL equivalent (fluctuates with rewards/slashing).
+
+| Function | Returns | Changes When |
+|----------|---------|--------------|
+| `balanceOf(user)` | Shares | Only on deposit/withdraw/transfer |
+| `getQRLValue(user)` | QRL equivalent | Rewards accrue or slashing occurs |
+| `getExchangeRate()` | QRL per share (1e18 scaled) | Rewards/slashing |
+
+**Key Features:**
+- Virtual shares/assets (1e3) prevent first-depositor inflation attacks
+- All ERC-20 operations work with shares, not QRL amounts
+- Tax-friendly: balance only changes on explicit user actions
+
+**Example:**
+```
+1. User deposits 100 QRL when pool has 1000 QRL / 1000 shares
+2. User receives 100 shares, balanceOf() = 100
+3. Validators earn 50 QRL rewards (pool now 1050 QRL)
+4. User's balanceOf() still = 100 shares (unchanged)
+5. User's getQRLValue() = 100 × 1050 / 1000 = 105 QRL
+```
+
+### DepositPool-v2.sol - User Entry Point
+
+Handles deposits, withdrawals, and reward synchronization.
+
+**Deposit Flow:**
+1. User calls `deposit()` with QRL
+2. Contract syncs rewards via `_syncRewards()` (trustless balance check)
+3. Shares calculated at current exchange rate
+4. `stQRL.mintShares()` called, shares minted to user
+5. `totalPooledQRL` updated
+
+**Withdrawal Flow:**
+1. User calls `requestWithdrawal(shares)`
+2. Shares burned, QRL amount calculated
+3. Request queued with 128-block delay (~2 hours)
+4. User calls `claimWithdrawal(requestId)` after delay
+5. QRL transferred from withdrawal reserve
+
+**Trustless Reward Sync:**
+- No oracle needed for reward detection
+- `_syncRewards()` compares contract balance to expected
+- Balance increase = rewards, decrease = slashing
+- EIP-4895 withdrawals automatically credit the contract
+
+**Key Parameters:**
+- `WITHDRAWAL_DELAY`: 128 blocks (~2 hours)
+- `MIN_DEPOSIT`: 1 ether (configurable)
+- `VALIDATOR_STAKE`: 10,000 ether
+
+### ValidatorManager.sol - Validator Lifecycle
+
+Tracks validators through their lifecycle:
+
+```
+None → Pending → Active → Exiting → Exited
+                    ↓
+                 Slashed
+```
+
+**State Transitions:**
+- `registerValidator(pubkey)` → Pending
+- `activateValidator(id)` → Active (confirmed on beacon chain)
+- `requestValidatorExit(id)` → Exiting
+- `markValidatorExited(id)` → Exited
+- `markValidatorSlashed(id)` → Slashed (from Active or Exiting)
+
+**Access Control:**
+- Owner can perform all operations (trusted operator MVP)
+- DepositPool can register validators
+
+## Security Model
+
+### Access Control
+
+| Contract | Role | Capabilities |
+|----------|------|--------------|
+| stQRL | Owner | Set depositPool (once), pause/unpause |
+| stQRL | DepositPool | Mint/burn shares, update totalPooledQRL |
+| DepositPool | Owner | Pause, set parameters, emergency withdraw excess |
+| ValidatorManager | Owner | All validator state transitions |
+
+### Attack Mitigations
+
+| Attack | Mitigation |
+|--------|------------|
+| First depositor inflation | Virtual shares/assets (1e3 offset) |
+| Reentrancy | CEI pattern, no external calls before state changes |
+| Withdrawal front-running | 128-block delay, FIFO queue |
+| Emergency fund drain | emergencyWithdraw limited to excess balance only |
+
+### Slashing Protection
+
+When slashing occurs:
+1. `_syncRewards()` detects balance decrease
+2. `totalPooledQRL` reduced proportionally
+3. All stQRL holders share the loss via reduced `getQRLValue()`
+4. Share balances unchanged (loss is implicit)
+
+## Zond-Specific Adaptations
+
+| Parameter | Ethereum | QRL Zond |
+|-----------|----------|----------|
+| Validator stake | 32 ETH | 40,000 QRL |
+| Block time | ~12s | ~60s |
+| Signature scheme | ECDSA | Dilithium (ML-DSA-87) |
+| Pubkey size | 48 bytes | 2,592 bytes |
+| Signature size | 96 bytes | ~2,420 bytes |
+
+## Test Coverage
+
+- **173 tests** across 3 test suites
+- stQRL-v2: 55 tests (shares, conversions, rewards, slashing)
+- DepositPool-v2: 63 tests (deposits, withdrawals, sync, access control)
+- ValidatorManager: 55 tests (lifecycle, slashing, batch operations)
+
+## Deployment Checklist
+
+1. Deploy stQRL-v2
+2. Deploy ValidatorManager
+3. Deploy DepositPool-v2
+4. Call `stQRL.setDepositPool(depositPool)` (one-time)
+5. Call `depositPool.setStQRL(stQRL)` (one-time)
+6. Call `validatorManager.setDepositPool(depositPool)`
+7. Transfer ownership to multisig (optional for mainnet)
+
+## Future Improvements
+
+- [ ] Multi-operator support (permissionless registration)
+- [ ] Two-step ownership transfer pattern
+- [ ] Pagination for `getValidatorsByStatus()`
+- [ ] On-chain integration between DepositPool and ValidatorManager
