  • We are envisioning Bella Virtuoso, a permissionless quantitative strategy platform built upon Uniswap v3 to connect strategists and investors.
  • We built the Tuner Simulator for Uniswap v3, the most robust simulator for strategy modeling and backtesting.

What We Accomplished in 2020 and 2021

This year has been fantastic for all of us at Bella.

DeFi Asset Management is Calling for Diverse Product Offerings

2021 has been a significant year for the DeFi industry as decentralized applications and ecosystems continue to boom. The total value locked in DeFi topped $162.25 billion, hitting a new all-time high. DeFi investors have different risk tolerance levels, therefore calling for more diverse and flexible asset management products to meet their demand.

  1. No reference/indicator to guide the LPs when setting up the proper price range,
  2. High gas fee for rebalancing,
  3. Most users have limited understanding of IL between V2 and V3, LPs tend to omit the fact that the concentrated liquidity of V3 will significantly reduce the exposure while only paying attention to the high IL.

Introducing Bella Virtuoso: Next Phase of Bella Protocol

Bella Virtuoso is a permissionless DeFi asset management platform that connects investors with the best LP strategies on Uniswap v3. The idea is to provide an inclusive solution for every type of investor and celebrate the wisdom of quant strategy composers. Bella Virtuoso lets you compose and invest in the strategies you deserve.

Why “Virtuoso”?

Financial instruments are not just about money. They are about a chance to align your investment goals with your financial realities. To reach your goals, it’s better if there’s a Virtuoso, a wizard or expert, of financial instruments to compose for you a fit strategy.

Who did we build Bella Virtuoso for?

Strategy builders


2021 Q4: Tuner Simulator for Uniswap V3

Tuner, a programmatic Uniswap V3 simulator allows strategy builders to backtest their strategies with mainnet data. Tuner simulator runs independently with high-fidelity that completely reproduces the intricate design and implementation of Uniswap V3, on a transaction-by-transaction basis without EVM. Tuner Simulator is fundamentally a state machine, it can fast-forward and rewind transactions and take or recover from a snapshot. The strategists can do advanced statistical analysis in real-time in a flexible way. The purpose of the Tuner Simulator is for the strategists to run near-to-perfect backtesting with on-chain historical data.

2022 Q1: Strategy Bot

Liquidity provision strategy execution bots that utilize statistical models to automatically adjust the price range of concentrated liquidity for maximizing capital efficiencies. This will allow investors to save themselves the time and gas fee of manually changing the price range to maximise the fund’s utilization rate.

2022 Q2-Q3: Bella Virtuoso

We are envisioning Bella Virtuoso as a platform to connect, educate and curate quant strategies. Both investors and quant strategists can benefit from Bella Virtuoso. The platform will also integrate automated backtesting features to facilitate the strategy-building process.

  • Permissionless strategy creation and listing on Bella Virtuoso by any strategy composers
  • Smart contract based fund management system that safeguards user fund
  • Visualization of past performance, backtesting historicals, and metrics such as Sharpe Ratio and Sortino Ratio
  • Elegant user interface and simplified user experience for choosing LP strategy
  • Easy-to-deploy strategy templates and combinations for strategy composers
  • Open source or not? The strategies are usually trade secrets in the traditional finance world, since the performance of a strategy degrades and eventually the strategy becomes obsolete when more and more people are using it. We are still in the design phase to decide how to manage the strategies in a decentralized and permissionless context.
  • How can the centralized strategy bot be permissionless? Since the smart contracts are always passively triggered, an active bot which has the ability to execute strategies based on data analysis and mathematical models can only be deployed and hosted centrally. We are still trying to figure out the best way to provide a neutral platform where the users have the ultimate control over their funds and strategies while making the setup much more intuitive and smooth.
  • More creators and engineers. To present the idea in the form of a product as soon as possible requires a lot of designs and engineering, and we would love to see more collaborators who have deep understanding of/are willing to learn about EVMs, Uniswap v3 and DeFi to join us.
