Run the Service

For Non-Stakers

Clone this repository locally and execute:

chmod +x run_service.sh
./run_service.sh

Answer 'No' when prompted:

Do you want to use staking in this service? (yes/no): n

For Stakers

Each staking program has different OLAS requirements. The script will check that your owner address meets the minimum required OLAS on the Gnosis Chain.

Clone this repository locally and execute:

chmod +x run_service.sh
./run_service.sh

Select your preferred staking program when prompted:

Please, select your staking program preference
----------------------------------------------
1) No staking
   Your Olas Predict agent will still actively participate in prediction
   markets, but it will not be staked within any staking program.

2) Quickstart Beta - Hobbyist
   The Quickstart Beta - Hobbyist staking contract offers 100 slots for
   operators running Olas Predict agents with the quickstart. It is designed as
   a step up from Coastal Staker Expeditions, requiring 100 OLAS for staking.
   The rewards are also more attractive than with Coastal Staker Expeditions.

3) Quickstart Beta - Expert
   The Quickstart Beta - Expert staking contract offers 20 slots for operators
   running Olas Predict agents with the quickstart. It is designed for
   professional agent operators, requiring 1000 OLAS for staking. The rewards
   are proportional to the Quickstart Beta - Hobbyist.

Find below a diagram of the possible status a service can be in the staking program:

Services can become staked by invoking the stake() contract method, where service parameters and deposit amounts are verified. Staked services can call the checkpoint() method at regular intervals, ensuring liveness checks and calculating staking rewards. In case a service remains inactive beyond the specified maxAllowedInactivity time, it faces eviction from the staking program, ceasing to accrue additional rewards. Staked or evicted services can be unstaked by calling the unstake() contract method. They can do so after minStakingDuration has passed or if no more staking rewards are available.

Notes:

• Staking is currently in a testing phase, so the number of trader agents that can be staked might be limited.

• Services are evicted after accumulating 2 consecutive checkpoints without meeting the activity threshold.

• Currently, the minimum staking time is approximately 3 days. In particular, a service cannot be unstaked during the minimum staking period.

• Once a staking program is selected, you can reset your preference by stopping your agent by running ./stop_service.sh and then running the command

  ./reset_staking.sh

  Keep in mind that your service must stay for minStakingDuration in a staking program (typically 3 days) before you can change to a new program.

Service is Running

Once the command has completed, i.e. the service is running, you can see the live logs with:

docker logs trader_abci_0 --follow

To stop your agent, use:

./stop_service.sh

Backups

Agent runners are recommended to create a backup of the relevant secret key material.

Observe your agents

1. Use the trades command to display information about placed trades by a given address:

   cd trader; poetry run python ../trades.py --creator YOUR_SAFE_ADDRESS; cd ..

   Or restrict the search to specific dates by defining the "from" and "to" dates:

   cd trader; poetry run python ../trades.py --creator YOUR_SAFE_ADDRESS --from-date 2023-08-15:03:50:00 --to-date 2023-08-20:13:45:00; cd ..

2. Use the report command to display a summary of the service status:

   cd trader; poetry run python ../report.py; cd ..

3. Use this command to investigate your agent's logs:

   cd trader; poetry run autonomy analyse logs --from-dir trader_service/abci_build/persistent_data/logs/ --agent aea_0 --reset-db; cd ..

   For example, inspect the state transitions using this command:

   cd trader; poetry run autonomy analyse logs --from-dir trader_service/abci_build/persistent_data/logs/ --agent aea_0 --fsm --reset-db; cd ..

   This will output the different state transitions of your agent per period, for example:

   

   For more options on the above command run:

   cd trader; poetry run autonomy analyse logs --help; cd ..

   or take a look at the command documentation.

Update between versions

Simply pull the latest script:

git pull origin

Remove the existing trader folder:

rm -rf trader

Then continue above with "Run the script".

Change the password of your key files

⚠️ Warning
The code within this repository is provided without any warranties. It is important to note that the code has not been audited for potential security vulnerabilities.

If you are updating the password for your key files, it is strongly advised to create a backup of the old configuration (located in the ./trader_runner folder) before proceeding. This backup should be retained until you can verify that the changes are functioning as expected. For instance, run the service multiple times to ensure there are no issues with the new password before discarding the backup.

If you have started you script specifying a password to protect your key files, you can change it by running the following command:

cd trader; poetry run python ../scripts/change_keys_json_password.py ../.trader_runner --current_password <current_password> --new_password <new_password>; cd ..

This will change the password in the following files:

• .trader_runner/keys.json
• .trader_runner/operator_keys.json
• .trader_runner/agent_pkey.txt
• .trader_runner/operator_pkey.txt

If your key files are not encrypted, you must not use the --current-password argument. If you want to remove the password protection of your key files, you must not specify the --new-password argument.

Advice for Mac users

In Docker Desktop make sure that in Settings -> Advanced the following boxes are ticked

Advice for Windows users using Git BASH

We provide some hints to have your Windows system ready to run the agent. The instructions below have been tested in Windows 11.

Execute the following steps in a PowerShell terminal:

1. Install Git and Git Bash:

   winget install --id Git.Git -e --source winget

2. Install Python 3.10:

   winget install Python.Python.3.10

3. Close and re-open the PowerShell terminal.

4. Install Poetry:

   curl.exe -sSL https://install.python-poetry.org | python -

5. Add Poetry to your user's path:

   $existingUserPath = (Get-Item -Path HKCU:\Environment).GetValue("PATH", $null, "DoNotExpandEnvironmentNames")
   
   $newUserPath = "$existingUserPath;$Env:APPDATA\Python\Scripts"
   
   [System.Environment]::SetEnvironmentVariable("Path", $newUserPath, "User")

6. Install Docker Desktop:

   winget install -e --id Docker.DockerDesktop

7. Log out of your Windows session and then log back in.

8. Open Docker Desktop and leave it opened in the background.

Now, open a Git Bash terminal and follow the instructions in the "Run the script" section as well as the subsequent sections. You might need to install Microsoft Visual C++ 14.0 or greater.

Advanced usage

This chapter is for advanced users who want to further customize the trader agent's behaviour without changing the underlying trading logic.

Policy weights

This script automatically sets some default weights to the agent's policy as a warm start. to help convergence and improve tool selection. These data were obtained after many days of running the service and are set here. As a result, the current weights are always deleted and replaced by this strategy which is considered to boost the initial performance of the service.

However, you may have found better performing policy weights and would like to remove this logic. It can easily be done, by removing this method call, here, in order to set your own custom warm start. Setting your own custom weights can be done by editing the corresponding files in .trader_runner. Moreover, you may store your current policy as a backup before editing those files, using the following set of commands:

cp ".trader_runner/available_tools_store.json" ".trader_runner/available_tools_store_$(date +"%d-%m-%Y")".json
cp ".trader_runner/policy_store.json" ".trader_runner/policy_store_$(date +"%d-%m-%Y")".json
cp ".trader_runner/utilized_tools.json" ".trader_runner/utilized_tools_$(date +"%d-%m-%Y")".json

Tool selection

Sometimes, a mech tool might temporarily return invalid results. As a result, the service would end up performing mech calls without being able to use the response. Assuming that this tool has a large reward rate in the policy weights, the service might end up spending a considerable amount of xDAI before adjusting the tool's reward rate, without making any progress. If a tool is temporarily misbehaving, you could use an environment variable in order to exclude it. This environment variable is defined here and can be overriden by setting it anywhere in the run_service.sh script with a new value, e.g.:

IRRELEVANT_TOOLS=["some-misbehaving-tool", "openai-text-davinci-002", "openai-text-davinci-003", "openai-gpt-3.5-turbo", "openai-gpt-4", "stabilityai-stable-diffusion-v1-5", "stabilityai-stable-diffusion-xl-beta-v2-2-2", "stabilityai-stable-diffusion-512-v2-1", "stabilityai-stable-diffusion-768-v2-1"]

Backup and Recovery

When executed for the first time, the run_service.sh script creates a number of Gnosis chain accounts:

• one EOA account will be used as the service owner and agent operator,
• one EOA account will be used for the trading agent, and
• one smart contract account corresponds to a Safe wallet with a single owner (the agent account).

The addresses and private keys of the EOA accounts (plus some additional configuration) are stored within the folder .trader_runner. In order to avoid losing your assets, back up this folder in a safe place, and do not publish or share its contents with unauthorized parties.

You can gain access to the assets of your service as follows:

1. Ensure that your service is stopped by running stop_service.sh.

2. Ensure that you have a hot wallet (e.g., MetaMask) installed and set up in your browser.

3. Import the two EOAs accounts using the private keys. In MetaMask, select "Add account or hardware wallet" → "Import account" → "Select Type: Private Key", and enter the private key of the owner/operator EOA account (located in .trader_runner/operator_pkey.txt):

4. Repeat the same process with the agent EOA account (private key located in .trader_runner/agent_pkey.json).

Now, you have full access through the hot wallet to the EOAs addresses associated to your service and you can transfer their assets to any other address. You can also manage the assets of the service Safe through the DApp https://app.safe.global/, using the address located in the file .trader_runner/service_safe_address.txt.

Terminate your on-chain service

If you wish to terminate your on-chain service (and receive back the staking/bonding funds to your owner/operator address in case your service is staked) execute:

./stop_service.sh
./terminate_on_chain_service.sh

RPC-related Error Messages

When updating the service, you may need to re-run the script if you obtain any of the following error messages:

Error: Service unbonding failed with following error; ChainTimeoutError(Timed out when waiting for transaction to go through)

Error: Component mint failed with following error; ChainTimeoutError(Timed out when waiting for transaction to go through)
