Using Osmosis with Hummingbot

cover

Introduction

These instructions help users navigate the installation, configuration, and operation of (OSS) Hummingbot high-frequency trading bot running Automated Market Making Arbitrage or Range Automated Market Making strategies on Osmosis DEX over the Hummingbot Gateway.

Prerequisites

Create an Osmosis (Cosmos) Wallet

The Cosmos ecosystem is powered by the Inter-Blockchain Communication protocol (IBC) which functions like an internet of blockchains. Most Cosmos wallets support all IBC chains natively, including Osmosis - though specific networks may need to be manually added.

Stay up to date with Osmosis-specific wallet information on the Osmosis website and/or Docs:

To ensure the ability to easily export the wallet private key, use Leap. Remember that the private key exported from Leap will include a ‘0x’ prefix which must be removed.

Fund the Wallet

There are multiple bridges to Cosmos available, but the easiest way is to directly deposit to Osmosis using the Osmosis DEX front end.

Note

Please ensure your wallet has sufficient balance, including OSMO for gas fees


Install Hummingbot

There are two main methods to install Hummingbot:

Docker

The recommended method for installing Hummingbot is using Docker.

Source

For advanced users who are comfortable using command line interface, installing from source allows for customization and private changes.

Guides for various environments:


Add Osmosis Wallet to Hummingbot

You will need to export the private key for your designated trading wallet. It is highly advised to have a dedicated account for this purpose.

Warning

Be aware an exported private key may have an 0x at the start, which may need to be removed to fit the private key format check.

→ Before: 0x1234567890...

→ After: 1234567890...

Export Private Key from Keplr

Keplr is the most popular Cosmos-based wallet. However, when creating a Keplr wallet, only users who link a Google Account are able to export their private key directly from Keplr.

Note

For a linked Keplr-Google wallet, find instructions to export the private key here.

To get around this, export the seed instead and then restore with a different Osmosis wallet which allows exporting private key.

To get a Keplr private key without a linked Google Account:

  1. Export Keplr seed phrase. image

  2. Restore the wallet using the seed phrase, in a different Cosmos-based wallet (such as Leap wallet) which allows exporting the private key. image

  3. Export the private key from the newly restored wallet.

Warning

Your wallet seed phrase is extremely sensitive. Keep it confidential and never share it online or with anyone you don't trust. Always ensure you're in a secure and private environment when handling your seed phrase.


Export Private Key from Leap

To export a private key from Leap wallet:

  1. Open Leap wallet and then open the wallet menu.

  2. Scroll down to the ‘Security’ section and select ‘Export Private Key’. image

  3. Enter the wallet password and proceed to view the private key by hovering the cursor over the blurred area.

  4. Copy down the private key and be sure to discard the ‘0x’ at the beginning of the displayed key. image

Note

Images made with Leap version 0.10.7 and Keplr version 0.12.70; in Chrome.

Add Private Key to Hummingbot

Run gateway connect osmosis and follow the prompts to add a trading wallet to the Osmosis DEX connector.

Note

Hummingbot stores both API keys and private keys on the local machine in encrypted form, with the Hummingbot client password as the key.

Gateway Connect

  • To connect to Osmosis mainnet run the command below
>>> gateway connect osmosis

  • To connect to the Osmosis testnet, select 'testnet' instead of 'mainnet' when prompted.

  • You will be prompted to enter your Osmosis private key. If valid, you should get a message saying The connector osmosis_osmosis_mainnet is now using wallet osmo

  • To confirm the connection, you can run the balance command below to see if Hummingbot is able to pull the available balance from the exchange

>>> gateway balance

Run a Strategy

To begin trading, a strategy must be configured. The two strategies supported natively by the Osmosis connector are amm_arb and amm_v3_lp.

Prepare

  1. If you haven’t already, connect a wallet to Osmosis Mainnet with gateway connect osmosis. Afterwards, you should be able to see your osmosis_osmosis_mainnet wallet when you run gateway balance.

  2. To display the balance of specific tokens in the trading wallet balance, run gateway approve-tokens osmosis_osmosis_mainnet <TOKEN_SYMBOL_HERE>. The token balance will be displayed the next time gateway balance is run.

  3. Ensure the added trading wallet has at least 1 OSMO to cover trading gas costs.

Create New Strategy

Use the create command to set up an amm_arb or amm_v3_lp strategy. Answer the question prompts presented so that you to generate your own version of the following example configurations.

>>> create

Example AMM_ARB Config

strategy: amm_arb
connector_1: osmosis_osmosis_mainnet
market_1: OSMO-USDC
connector_2: uniswap_polygon_mainnet
market_2: USDC-WOSMO
min_profitability: 1.0
market_1_slippage_buffer: 1.0
market_2_slippage_buffer: 1.0
concurrent_orders_submission: false
debug_price_shim: false
gateway_transaction_cancel_interval: 600

Example AMM_V3_LP Config

strategy: range_amm
connector: osmosis_osmosis_mainnet
market: OSMO-USDC
fee_tier: MEDIUM
price_spread: 1.0
amount: 1.0
min_profitability: 1.0

Import a Strategy

Run import to get a list of locally stored files, use the arrow keys or tab to scroll and select one. Or, you can also skip the prompt by running import <file_name.yml> directly.

>>> import

image

If successful, you will see:

image

Start a Strategy

To run a trading strategy:

  1. Ensure a strategy is loaded and Preliminary checks are confirmed.

  2. Run start.

Note

The amm_arb strategy will first request confirmation of selected wallets.

image

Use a Script

Scripts can be created similar to strategies, by using the create --script command.

>>> create --script

Modify Strategy or Script Config

Modifications can be made to strategies and scripts by manually editing the file:

  1. Locate the hummingbot/scripts folder and open the relevant file using any text editor or an IDE like Visual Studio Code.

  2. Make the desired changes and save.

  3. Restart Hummingbot and run the command below to start the bot again:

>>> start <strategy_name.yml>

Or, if using scripts:

start --script <script_name.py>


Useful Commands

You can run the status command shown below or press CTRL + S to check the bot status:

status

Note

The status command currently has a issue with amm_v3_lp strategy.

Known Issues

  • V1 Strategy compatibility for amm_arb and amm_v3_lp are in development.
  • The fee tier ‘LOWEST’ is not supported and will result in an error.
  • In some cases, the token pair must be in alphabetical order.
  • PoolPrice RPC may time out intermittently which results in an error 500.

Potential Improvements
