Trading is the killer application of Web3.
This is the Github repository for Citade-Sashimi EthDubai hackathon project. The project implements non-custodial investable automated trading strategies on the top of Sushi DEX.
The hackathon comes with one example trading strategy, but it's easy to customise the approach for multiple professional-grade quant finance strategies. The strategies can be written in high-elvel Python, using on-chain data sources and 150+ technical indicators out of the box. No Solidity or low level blockchain knowledge is needed.

Citade-Sashimi benefits decentralised finance users and Sushi
- For DeFi users the project offers professional grade investable trading strategies with features like portfolio rebalancing, stop loss alpha signals, position risk sizing and liquidity awareness. The advanced risk management features of the automated strategy make DeFi trading safer for users than what they would likely to be executed manually.
- For cryptocurrency traders non-custodial DeFi is safer than hack prone and opaque centralised services like FTX or 3Commas. No need to share API keys.
- For Sushi and its liquidity providers the project offers high quality market taker volume.
- For strategy developers there is high-level, easy to use, and much more powerful tooling what mere Solidity smart contracts can do. There is also opportunity for profit-sharing as Enzyme Vaults offer on-chain fund management features.
The trading strategies are based on real yield that comes for trading profits. Typical active trading strategies may include strategies like mean reversion, momentum and trend following. Active trading provides more sustainable yield than liquidity mining, as it is based on true profits.
In this hackathon we created
- Sushi adapter smart contract for Enzyme Vaults, so that trading strategies can perform rebalances using Sushi liquidity (see source, see Polygon smart contract)
- Trading Strategy backtesting and strategy development notebook for [creating trading algorithmic on the top of Sushi trading pairs and market data feeds].
- Demo website cidate-sashimi.com which allows you to connect the wallet and invest the Enzyme Finance vault smart contract that is controlled by Trading Strategy oracles
- The trading strategy source code was developed by the hackathon team
- The trading strategy oracles run the the strategy source code offchain
- Oracles send trade instructions to the Enzyme vault smart contract using Sushi adapter
- The vault trades on Sushi DEX
- Users can invest and withdraw to the vault
- The vault automatically calculates profit sharing, shares, etc.
A bit of the example trading strategy Python source code:
We created an example trading strategy based on portfolio construction methodology.
We performed a backtest
- The strategy performance and cash reserves are denonimated in USDC
- Only long positions, spot market
- Trade on Sushi DEX, Polygon only
- Momentum trading
- Rebalance every 4 days
- Choose top three assets based on alpha signals
- Risk management:
- Have min. available liquidity USD 300k for each asset traded
- Take profit triggers at 33%
- Stop loss triggers at 3%
- Use 1/nth portfolio allocation
- Maintain 50% cash buffer
- As a long only strategy, for the capital preservation, don't trade on bear market, indicated by MATIC token 15 days simple moving average (SMA) price
- Strategy performance
- Backtesting 2022-01-01 - 2023-02-01 (396 days)
- Annualised estimated return 60%
- LP fees paid ~$1000
- Max pullback -10%
- An example strategy. Currently the hackathon entry misses some performance calculation elements
- Three leg swaps may have fees calculated incorrectly (MATIC->USDC->base token)
- Price impact is not considered - we assume 300k liquidity is enough for trading
- Token tax tokens are not ignored
The strategy performance vs. buy-and-hold MATIC, BTC and ETH. You can see the equity curve is more beautiful due to tighter risk management
Statistics about the example strategy performance and the risk of individual trades taken:
See the full strategy notebook backtesting results on Github for more statistics, or run the backtest yourself using the instructions below.
Note Because the strategy performs rebalance trades ~once per week, we cannot show any live trading results within the EthDubai hackathon period. We did some initial smoke testing trades using Python scripting to show that the live portfolio rebalance works against Sushi liquidity.
- Polygon blockchain for the underlying chain
- Sushi DEX for the trading venue
- Enzyme Finance vaults smart contracts for managing strategy portfolio, investor shares and profit sharing
- Trading Strategy oracle for market data feeds, strategy development and backtesting
- Foundry for smart contract development
- SvelteKit frontend for the website
For building the project you need
- Foundry
- Python
- Poetry
This repository contains Git submodules.
Include them:
git submodule update --init --recursive We have one in-house adapter contract and then a complex suite of contracts from other protocols.
- Contract compilation and deployment is managed by Forge
- Depends on Enzyme and OpenZeppelin
- Enzyme protocol is used for the investment vault
- Enzyme protocol is already deployed on Polygon
- We deploy a special Enzyme vault that is using custom SushiAdapter for connecting trade instructions to the investment vault and then to Sushi protocol
- Enzyme protocol is already deployed on Polygon, so we do not deploy it
- The Trading Strategy oracle is set up as a fund manager for the vault
Live on Polygon mainnet. See the deployed contracts on PolygonScan
- Sushi adapter for Enzyme Protocol and Trading Strategy oracle
- Deployed Enzymy vault -Deployed Enzyme comptroller
To compile:
cd forge
forge build The vault is deployed and configured using hackathon/deploy.py
- Currently there is only one inhouse smart contract that is Enzyme-Sushi-Trading Strategy adapter
- We depend on web3-ethereum-defi package that contains 600+ precompiled Defi smart contracts
- We deploy Enzyme vault using our deployment script, ABI files from
web3-ethereum-defiand ABI files we compiled using Forge

To install
shell poetry install
To open the backtesting Jupyter notebook for the strategy development locally:
poetry shell
jupyter lab notebookThe automated trading strategies offer the same simplified user experience as yield farming. The end user of DeFi needs only three buttons: Connect wallet, invest, withdraw.
- View the demo website www.citade-sashimi.com
- Frontend is written in SvelteKit.
- Oracle is the server-side process the market feeds and drives strategy
- Run trade-executor Python package to run the oracle
- Oracle is deployed manually using Docker
- Oracle trades once in a week so unfortunately we could not demostrate any live trading in hackathon
- Deployment instructions are in the trade-executor documentation
- Multiple oracles can be deployed and configured to voting to make oracle execution decentralised
