Our Mission

Balancer Fi's mission is to accelerate the development of decentralized finance by providing the most powerful and flexible AMM infrastructure available. We believe that open, composable, and permissionless financial primitives are the foundation of a fairer global economy.

Since our inception, Balancer Fi has pioneered innovations like weighted pools, boosted pools, yield-bearing LP tokens, and hooks — tools that allow anyone to build novel financial products on top of a trusted, audited foundation.

With the launch of Balancer Fi v3, we've made it simpler than ever to create custom AMMs, integrate liquidity hooks, and prototype entirely new invariant designs — democratizing access to sophisticated DeFi primitives.

"AMMs made easy." Balancer Fi is a battle-tested toolkit for true AMM experimentation and innovation — designed so builders can ship faster, LPs can earn more, and traders can get better prices.

What Balancer Fi Builds

Flexible Liquidity Pools

Balancer Fi supports weighted pools, stable pools, boosted pools, CoW AMM pools, Gyroscope concentrated liquidity, and QuantAMM auto-rebalancing — all under one unified protocol with shared security guarantees.

Yield Optimization

Through boosted pool architecture, liquidity providers on Balancer Fi can earn swap fees while idle capital is simultaneously deployed to external yield protocols like Aave, Fluid, and Morpho, maximizing returns without extra steps.

Builder Toolkit

With Balancer Fi v3, developers can build entirely custom AMMs with novel invariants, attach hooks to pools for custom logic, and use the Scaffold Balancer starter kit to prototype and ship DeFi applications in record time.

Battle-Tested Security

Balancer Fi has been rigorously audited by multiple leading security firms and has an active bug bounty program on Immunefi. Our smart contracts have secured billions of dollars in liquidity since 2020.

Protocol Governance

Balancer Fi is governed by veBAL holders — community members who lock BAL tokens to gain voting rights over protocol parameters, liquidity incentive allocations, and strategic initiatives across all supported networks.

Multi-Chain Deployment

Balancer Fi is deployed on Ethereum, Arbitrum, Base, Polygon, Avalanche, Gnosis, and Optimism, as well as emerging networks like Monad and HyperEVM — ensuring deep liquidity wherever DeFi users transact.

Supported Networks

Balancer Fi is a truly multi-chain protocol. Our liquidity infrastructure is live on more than ten blockchain networks, providing consistent DeFi services to users regardless of which chain they prefer.

Whether you're providing liquidity on Ethereum mainnet, using gas-efficient pools on Arbitrum, or exploring next-generation networks like Monad, Balancer Fi brings the same powerful, audited pool infrastructure to every chain.

Token & Governance

BAL is the native governance token of Balancer Fi. Token holders can lock BAL to receive veBAL (vote-escrowed BAL), granting them voting power over protocol governance and the ability to direct liquidity incentives.

The veBAL system aligns long-term incentives between the protocol and its most committed stakeholders. Gauge voting allows the community to direct BAL emissions toward liquidity pools, fostering deep, sustainable DeFi liquidity across the ecosystem.

Protocol History

2020

Balancer Fi v1 Launches

The first version of Balancer Fi introduces the concept of customizable weighted pools, allowing any combination of up to 8 tokens with arbitrary weight ratios — a major leap beyond 50/50 AMMs.

2021

Balancer Fi v2 & BAL Governance

v2 introduces the unified Vault architecture for gas-efficient swaps across multiple pools, along with the BAL token governance model and the launch of veBAL for protocol voting.

2022

Boosted Pools & Multi-Chain Expansion

Balancer Fi introduces boosted pools that integrate with Aave, maximizing yields for LPs while maintaining deep liquidity. Deployment expands to Arbitrum, Polygon, Avalanche, Gnosis, and Optimism.

2023

CoW AMM & Partner Integrations

Partnership with CoW Protocol brings MEV-capturing AMM pools to Balancer Fi, offering LPs LVR protection. Gyroscope concentrated liquidity pools and QuantAMM auto-rebalancing pools further expand the pool type ecosystem.

2024–2025

Balancer Fi v3 & Next-Gen Networks

v3 reimagines the developer experience with modular pool hooks, simplified custom AMM creation, and expanded multi-chain deployments including Monad, HyperEVM, and Base — powering the next wave of DeFi innovation.

Why Balancer Fi?

Balancer Fi stands apart from other AMM protocols through its unmatched flexibility. While many protocols offer a single pool type, Balancer Fi provides a growing library of pool architectures — each optimized for specific use cases — all sharing the same security-reviewed Vault infrastructure.

Open Source & Transparent

All Balancer Fi smart contracts are open source and publicly verifiable on GitHub. On-chain governance ensures that protocol changes are transparently proposed, debated, and voted on by the community before implementation.

Ecosystem Partnerships

Balancer Fi has deep integrations with Aave, CoW Protocol, Gyroscope, QuantAMM, Fluid, Morpho, and dozens of other DeFi protocols — creating a rich ecosystem of composable financial infrastructure built on top of our shared liquidity layer.

Our Core Values

Openness

We believe DeFi infrastructure should be permissionless and open to everyone. Balancer Fi allows any developer or liquidity provider to participate without gatekeeping or approvals.

Security First

Security is never an afterthought at Balancer Fi. Every protocol upgrade undergoes rigorous auditing, formal verification where applicable, and a phased rollout to minimize risk to user funds.

Innovation

Balancer Fi has a long history of pioneering DeFi primitives — from weighted pools to boosted yield strategies to modular hooks. We continuously push the boundaries of what's possible in on-chain finance.

Community

The Balancer Fi community of over 326,000 liquidity providers, developers, and governance participants is the protocol's greatest strength. Every voice matters in shaping the future of Balancer Fi.

Sustainability

Long-term protocol health matters as much as short-term growth. Balancer Fi's fee model, veBAL incentive structure, and treasury management are designed to sustain the protocol for decades.

Composability

Every component of Balancer Fi is designed to integrate seamlessly with the rest of DeFi. LP tokens, hooks, routers, and price oracles are all designed to be used by other protocols in the ecosystem.
