TL;DR : You can get a summary of this article on its last section
Balancer is an automated market maker (AMM) platform based on an N-dimensional invariant surface , a variation in design to the formula used by Uniswap , that allows for multi-asset pools that balance , like an index fund. This has many implications for mitigating impermanent loss , asset management, and certain trading strategies.
In this article, we will provide a review of Balancer where we will dive into the team behind the protocol, its design, and the ecosystem supporting it. By doing this, we hope to better assess the impact of Balancer to the rest of decentralized finance (DeFi) and Crypto at large.
In this analysis of Balancer, we will cover 5 different sections, as follows:
- summary .
Balancer was founded by Fernando Martinelli
, a Brazilian serial entrepreneur and longtime Maker
community member, as a project of Balancer Labs. Since early 2018, the fundamental design of Balancer was being tested as a project on BlockScience
. Martinelli and former Maker
technical partner Nikolai Mushegian published the Balancer Whitepaper
in late 2019. The team then brought Mike McDonald, creator of
, to build the platform. In it, they detailed how a Balancer pool would build on the constant product market maker of Uniswap with a constant value market maker capable of functioning as a self-balancing weighted portfolio and a price sensor .
Balancer did not do an ICO. They simply launched their product in early 2020. In March 2020, they raised a $3M seed round by Placeholder and Accomplice . In June 2020, Balancer followed Compound in launching a governance token, $ BAL , becoming the second-ever DeFi project to do so. Before the launch of $ BAL , Balancer had $40M in total value locked (TVL) . Today, Balancer is the fourth-largest DEX after Curve , Uniswap , and SushiSwap and over $600B in TVL.
The goal of Balancer is to provide a flexible platform for programmable liquidity. In Balancer, anyone can create a pool with several assets, potentially simulating their whole portfolio. Instead of paying fees for portfolio managers to use rebalancing strategies and actively manage the fund, the pool balances itself. At the choice of liquidity providers (LPs) , they can set up a pool with up to 8 tokens and specify any custom percentage-distribution to maintain, or add their liquidity to an existing pool. Moreover, LPs can also set their own fees for their pools. LPs can even set a fully private pool, where only they are allowed add liquidity. At this point, it helps to compare Balancer with Uniswap , a very straight-forward DEX that’s also based on the AMM model.
|Max no. of supported tokens per pool||2||8|
|Relative weight of assets in pool||1:1||custom|
|LP token||for bookkeeping||functional ERC-20|
|Pricing mechanism, internal||trade-based||trade-based|
|Pricing mechanism, adjustments||relies on arbitrageurs||relies on arbitrageurs|
|Trading fees||0.30%||set by LPs, per pool|
|Governance token||$ UNI||$ BAL|
The core differentiating feature of Balancer is its multi-asset pools with custom percentage-weighing. The benefits of this approach are two-fold. First, swapping orders from the DEX side can be optimized to offer better prices and lower slippage, since an asset can be in many pools at once. Second, the LP may optimize the weight-distribution of his pool depending on his view of the market i.e. if the LP is long on one asset over others in the same pool, then the pool can be set with the favored asset having a greater weight. These advantages in slippage, pricing, and pool dynamics create a flywheel effect for Balancer.
Just like many other core DeFi applications, anyone — a user, a smart contract, or a DAO — can create a Balancer pool. Balancer thus represents a new DeFi primitive to provide novel use cases and experiences in DeFi tools and applications. Based on this architecture, interesting use cases like smart pools can be created which are controlled by a smart contract. One example of a private smart pool is the liquidity bootstrapping pool (LBP) template by the Balancer team which serves to create deep liquidity for a new token issue without having to resort to expensive market making.
The Balancer Protocol was launched without a native token. LPs received fees that traders paid when using the DEX. No other intermediate steps were needed. This is an optimal tokenomics design, without the need for adding an additional token for “internal payments” when none is needed.
Balancer decided to launch $ BAL
, given the success of Compound
’s $ COMP
token as a model for further decentralization and as an incentive to attract liquidity with the novel liquidity mining phenomenon. As a governance token, it does not add an extra step to using the DEX either as a trader or an LP. Instead, it can be “mined” or “farmed” by LPs. There is a total supply of 100M tokens, where the team, future investors, and the ecosystem fund have reserved 35M with different conditions. The remaining 65M are being distributed at a rate of 145k per week, which if unchanged would mean 8.6 years to finish the distribution. To earn some of the distribution, add liquidity to any Balancer pool, the rewards are distributed weekly, automatically. To be eligible, at least two tokens in your pool must be priced in CoinGecko. The lower the pool fees, the more is awarded, according to a multiplier called
feeFactor . More is also awarded to “useful liquidity”, using another multiplier called
wrapFactor , to penalise pairs which are “soft-pegged” like USDC
. These incentives may evolve, as the liquidity mining program
is under the direction of Balancer governance.
$ BAL can be found with most liquidity in Balancer, unsurprisingly. Check the exchanges where you can find with most volume and liquidity.
|Balancer||BAL / wETH , BAL / wBTC|
|Binance||BAL / USDT , BAL / BTC , BAL / BNB , BAL / BUSD|
|OKEx||BAL / USDT , BAL / BTC|
|Uniswap||BAL / wETH|
|Huobi||BAL / USDT , BAL / ETH|
Here is an snapshot of the most popular pools on Balancer, according to
|(50%) DAI / (50%) wETH||$58.5M||$11.1M|
|(50%) wBTC /(50%) wETH||$55.6M||$6.62M|
|(80%) BAL /(20%) wETH||$52.7M||$9.09M|
|(50%) USDC /(50%) wETH||$47.3M||$8.65M|
|(50%) YFI /(50%) wETH||$36.6M||$2.39M|
Balancer has an vibrant and engaged ecosystem. As a DEX, its classical ecosystem players are traders who use the service and liquidity providers (LPs) who make the market. However Balancer is also an increasingly more decentralized protocol so $BAL holders are an important constituency. Finally, Blockchain devs , DeFi architects , and others who
#buidl </code> are important to the rest of the Balancer community as the protocol is also a DeFi primitive, a permissionless component whose functions can be composable or made to work together with other DeFi apps.
Balancer Ecosystem Fund
A total of 5M tokens have been set aside for strategic partnerships. This fund is currently valued at over $100M. At the moment, no grants or withdrawals have been made from it and there hasn’t been announcements as to its future use. Given the background of the founding team with Maker , we can probably expect a cohort-like approach to grant-making.
There is a detailed explanation in the Balancer docs of core concepts, as well as coding examples and instructions for working with the Balancer protocol, whether through smart contracts or its DEX trading interface via API. The mathematics behind Balancer pools, and the smart order routing of the Balancer DEX are also described therein, as are the functions of Balancer pool tokens and the security of the protocol.
Partnerships Community | Governance | Roadmap
Balancer considers its current version its Bronze release . The Silver release with optimised gas usage and a few architectural improvements for more flexible use cases is planned for the end of the year. It is unclear what the Golden release will entail since the design is ongoing and the DeFi landscape is continuously evolving.
The Balancer team is trying hard to decentralize as many decisions on governance as possible. Albeit the share of controlled by the community at the moment is not significant, the level of involvement is high.
Balancer has developed a gasless governance tool in
. The tool works off-chain by tracking blockchain blocks to conduct polling, and integrating with the Web3 stack. This allows for the pool to see who held which tokens during the voting process. Both proposals and votes are stored on IPFS as signed messages. The tool has been made open-source and it is free to create proposals and vote. The Snapshot docs
contain all the information you need to set up a space. Aragon
even developed a plug-in for on-chain execution
. Many projects are using snapshot-based voting: yEarn
, and SushiSwap
, to name a few. The project has taken a life of its own.
Balancer provides a new substrate for DeFi pools with varied and unique use cases. For your run-off-the-mill LP, it gives the option to adjust his exposure to the market while he makes fees. For the average user, it provides a way to make a self-balancing Crypto index of sorts, and invest in it while earning fees. Its DEX also provides a different way of price discovery and thus affordability and low-slippage. That’s a lot of programmability, in a protocol that’s only been live for a few months. Expect more from the talented team at Balancer.
