Balancer allows users to add to liquidity pools to earn $BAL, which is automatically awarded to the users weekly. Top exchanges that support $BAL include Binance, ZenGo, Global, HBTC, Kraken, OKEx, Huobi, etc. To learn how to exchange your fiat currencies for $BAL, here is a detailed [guide](https://coinmarketcap.com/how-to-buy-bitcoin/) on how to go about that.

For Balancer, security is a top priority and that is why the protocol has been fully audited three times by Trail of Bits, ConsenSys and OpenZeppelin. There are no admin keys or backdoors, hence, making it trustless, and the balancer pools are not upgradeable. Balancer does not support tokens that do not conform to the [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) standard, even though they may be in use on some pools. The tokens held on Balancer pools are not controlled by Balancer, but are smart contracts. Nevertheless, that does not remove the inherent risks of smart contracts. The configurable rights pools (CRPs) ensure that tokens with known issues are barred from being used in pools. It further ensures that all other tokens safely interact with the protocol

Balancer is similar to [Uniswap](https://uniswap.org/) and [Curve](https://www.curve.fi/), in that it enables anyone to create pools of tokens. The pool adjusts itself to keep the tokens equally weighted regardless of changes in their price. However, [one unique feature](https://coinmarketcap.com/alexandria/article/what-is-decentralized-finance) of Balancer is that more than one token can be added and ETH isn’t required. Although, Balancer isn’t the first DeFi protocol to make use of AMMs, however, it has brought a new face and approach to liquidity. The unique feature of the protocol is that it allows Liquidity providers to have up to eight assets per market which are weighted by percentage and rebalanced automatically. With Balancer, users don’t have to deposit 50% of the desired asset, but are allowed to decide how much of a supported asset they wish to deposit. Another unique feature of Balancer Lab is that users can make a high return on assets that are in low demand through arbitrage opportunities and slippage-reduction.

Balancer wasn’t launched with a native token. However, in June 2020, they launched a governance token, $BAL, following the success of Compound’s token COMP. The purpose of the token is to allow for more decentralization and as an incentive for LP. Of the total 100M tokens that were created, 25M were reserved for the team, core developers, investors and advisors. 5M tokens were allocated for the Balancer Ecosystem Fund, which would be used as incentives for strategic partners. Another 5M were allocated for the fundraising fund. This fund will be used by Balancer to support its operation and growth at future fundraisings. The remaining tokens are to be mined by liquidity providers on the platform and are released at a rate of 145K per week. Provided the distribution rate is kept constant, it would take approx. 8.6 years to finish distributing the tokens.

Balancer Lab was founded by Fernando Martinelli and Mike McDonald, but it began as a research program at a software firm “BlockScience” in 2018. The Balancer project features intelligent, like-minded fellows with an acute understanding of the DeFi space.

Balancer is an automated market maker ([AMM](https://coinmarketcap.com/alexandria/glossary/automated-market-maker-amm)) that was developed on the Ethereum blockchain and launched in March 2020. It was able to raise a $3M seed round by Placeholder and Accomplice. [Balancer protocol](https://coinmarketcap.com/alexandria/article/what-is-balancer) functions as a self-balancing weighted portfolio, price sensor and liquidity provider. It allows users to earn profits through its recently introduced token ($BAL) by contributing to customizable liquidity pools. To learn more about this project, check out our deep dive of [Balancer](https://coinmarketcap.com/alexandria/article/what-is-balancer. The protocol operates a few types of pools: * Private pools give the owner governance over the pool, and make the person the sole contributor of liquidity to the pool. Also, all the parameters are mutable by the owner. * Shared pools are for those who want to become [liquidity providers](https://coinmarketcap.com/alexandria/glossary/liquidity-provider) (LPs). The LPs are rewarded with the Balancer Pool Tokens (BPTs). * Smart pools are similar to private pools but are controlled by a smart contract. They also reward using BPTs and allow anyone to contribute liquidity to the pool.
