Balancer protocol
Overview
Balancer is a decentralized automated market maker (AMM) protocol on Ethereum that enables multi-token pools with customizable weights. It is used for decentralized trading, liquidity provision, and portfolio management, allowing pools of up to eight tokens with arbitrary weight distributions. Balancer also introduced Liquidity Bootstrapping Pools (LBPs) for fair token launches.
Within the DeFi Intel graph, Balancer connects to 18 tracked entities, most strongly to Ethereum, Hidden Hand, Stake DAO.
Incident (2025-11-03): Balancer V2 Composable Stable Pools (CSPv5) were exploited for approximately $128M across Ethereum, Base, Arbitrum, Polygon, Optimism and Sonic, caused by a rounding error in the pool invariant calculation. Balancer V3, which uses a different architecture, was not affected. (as of 2026-07-15)

Frequently asked questions
What is Balancer?
Balancer is an AMM protocol that allows users to create liquidity pools with up to eight tokens and customizable weights, enabling automated portfolio rebalancing and decentralized trading.
How are Balancer pools different from Uniswap pools?
Unlike Uniswap's constant product formula for two tokens with 50/50 weights, Balancer pools can hold multiple tokens with arbitrary weight ratios, offering more flexibility for portfolio management and reducing impermanent loss for certain strategies.
What are Liquidity Bootstrapping Pools (LBPs) on Balancer?
LBPs are a specialized pool type designed for fair token launches, where the weight of the project token starts high and decreases over time, discouraging early large buys and allowing gradual price discovery.
What is Balancer connected to?
In the DeFi Intel knowledge graph, Balancer is linked to 18 other tracked entities, most strongly to Ethereum, Hidden Hand, Stake DAO.
