# Compound V3 (Comet) Integration

## Architecture

Compound V3 (Comet) is a fundamentally different design from V2. Each Comet deployment is a single-asset market — one base asset (e.g., USDC) with multiple collateral assets. There are no cTokens; the Comet contract itself tracks balances.

| Component | Description |
|-----------|-------------|
| `Comet` | Core market contract (one per base asset) |
| `CometRewards` | Claims COMP rewards for suppliers/borrowers |
| `Configurator` | Governance-controlled parameter updates |
| `BulkerV2` | Batch operations including native ETH wrapping |

## Supply / Withdraw Base Asset
