Balancer is a protocol for programmable liquidity. A Balancer Pool is an automated market maker with certain key properties that cause it to function as a self-balancing weighted portfolio and price sensor. Balancer turns the concept of an index fund on its head: instead of paying fees to portfolio managers to rebalance your portfolio, you collect fees from traders, who rebalance your portfolio by following arbitrage opportunities.
