Balancer
Liquidity · Pools · BAL
Balancer is a generalized AMM supporting up to 8 assets per pool with arbitrary weights (not just 50/50), used for index-style pools and structured liquidity. V3 (2024+) added hooks.

Weighted Pools
Generalized AMM pools holding up to 8 assets with arbitrary weightings (not limited to the 50/50 of constant-product AMMs), enabling index-fund-like self-rebalancing portfolios.
Composable Stable Pools
Pools optimized for assets expected to trade near parity (e.g. stablecoins, LSTs), using a StableSwap-style invariant and exposing the pool's own BPT for nested/composable pooling.
Boosted Pools
Pools that forward idle liquidity to external lending markets (e.g. Aave, Morpho) so LPs earn yield on the underlying while still providing swap liquidity; in V3 up to 100% of a position can be boosted in yield-bearing tokens.
The Vault
A single contract (introduced in V2) that holds and accounts for all pool assets, separating token accounting from pool math; V3 adds transient accounting via EIP-1153.
Hooks (V3)
A framework letting developers extend pool behavior at lifecycle points (e.g. the StableSurge hook that raises swap fees during volatility to defend stable-asset pegs).
veBAL Governance
Vote-escrow system where users lock the 80/20 BAL/WETH pool token (BPT) for up to 1 year to receive veBAL, granting governance voting power, gauge vote direction, and a share of protocol fees.
Differentiator
Arbitrary-weight, multi-asset pools enable index-style and boosted liquidity; Composable Stable Pools and V3 hooks extend programmability.

Similarity to traditional finance products
How Balancer maps onto established TradFi structures, and where it diverges.
| TradFi product | Similarity to Balancer | Key differences |
|---|---|---|
| Index fund / ETF (e.g. an equal-weight index) | A Balancer weighted pool holds a basket of assets at target weights and continuously rebalances toward them, like a self-rebalancing index fund. | Rebalancing is done by arbitrageurs against market prices rather than a fund manager; instead of charging a management fee the pool earns swap fees, and there is no custodian or redemption gate. |
| Automated market-making / dealer desk | Provides continuous two-sided quotes and earns the spread (swap fee) for supplying liquidity. | Fully on-chain, permissionless, non-custodial, and governed by veBAL holders rather than an institution. |
