Balancer is a decentralized finance protocol built on Ethereum, utilizing automated market maker technology. Its unique 'Vault' architecture centralizes token management and accounting in a singleton contract, enabling flexible and secure custom pool designs.

The protocol supports various pool types including Weighted, Boosted, and concentrated liquidity models. This provides developers with flexible AMM tools while offering liquidity providers access to yield-bearing opportunities with MEV protection across its expanding decentralized exchange ecosystem.
