Balancer DEX

Overview

Balancer is a next-generation automated portfolio manager and decentralized exchange (DEX) built on the Ethereum and other EVM-compatible blockchains. It allows users to create or invest in customizable liquidity pools that automatically rebalance portfolios while earning swap fees.

Unlike traditional DEXs with fixed 50/50 token ratios, Balancer enables pools with up to 8 tokens and custom weightings. This makes it a powerful tool for traders, liquidity providers, and developers seeking programmable liquidity and efficient on-chain trading.

How It Works

Balancer works by using mathematical formulas to maintain token balances and execute swaps. When a user swaps one token for another, the pool’s token ratios are adjusted while charging a small fee. Liquidity providers earn a portion of these fees based on their share of the pool.

1. Users provide liquidity to pools with custom token ratios (e.g. 80% WETH / 20% BAL).
2. Traders swap tokens through these pools with minimal slippage.
3. The protocol auto-rebalances weights and distributes fees to LPs.
4. Smart order routing finds the best price across all Balancer pools.
