Balancer V2 is a next-generation automated market maker (AMM) protocol on Ethereum and other EVM-compatible chains. It builds on the innovation of Balancer V1 to deliver greater capital efficiency, flexibility, and gas optimization — making it one of the most powerful DeFi tools for liquidity providers, traders, and developers.

🔍 What Makes Balancer V2 Unique?

1. Protocol Vault Architecture

• Single Vault for all assets: Instead of each pool holding its own tokens, all assets are stored in one central vault.
• Separation of logic and assets: Pool logic and token accounting are handled separately, improving gas efficiency and security.

2. Customizable AMMs

• Developers can create custom pool types (e.g., weighted pools, stable pools, managed pools).
• Allows experimentation and advanced use cases, such as:
  • Smart order routing
  • Dynamic fees
  • Composable DeFi strategies

3. Multi-Token Pools

• Supports up to 8 tokens per pool with custom weightings.
• Useful for index-like products, diversified yield farming, and advanced trading pairs.

4. Gas Efficiency

• By storing all tokens in a single vault, Balancer V2 reduces redundant approvals and transfers, lowering gas fees significantly.

💰 Use Cases

• Liquidity Providers (LPs): Provide liquidity to any custom pool and earn trading fees and BAL incentives.
• Traders: Swap tokens efficiently with low slippage, especially in stable or low-volatility pools.
• DeFi Projects: Build innovative AMMs or structured products on top of the Balancer Vault.

🌐 Supported Pool Types

• Weighted Pools (e.g., 80/20 or 50/50 BAL/ETH)
• Stable Pools (optimized for assets with similar prices like USDC/DAI)
• Boosted Pools (integrate with protocols like Aave for yield on idle assets)
• Composable Stable Pools (like Curve-style nested assets)

🛡️ Governance and Token (BAL)

• BAL is the governance token for the Balancer DAO
• Used for voting on protocol parameters, incentives, and pool approvals
• Can be staked for veBAL to boost yield and participate in governance
