Prediction Markets

This is a demo that allows a user to run a market creator service and a trader service via a script.

To get started, the user must mint the services on-chain and populate two .env files as follows:

1. .creator.env: this environment file should contain the variables for the market creator service
2. .trader.env: this environment file should contain the variables for the trader service

System requirements

• Python == 3.10
• Pipenv >=2021.x.xx
• Tendermint ==v0.34.19

The script automatically installs Tendermint v0.34.19 if it is not present in your system.

Instructions

Two Gnosis addresses, and corresponding secret keys, are recommended to be created for this demo:

• Gnosis address #1 is associated with the trader agent, and you need to associate the TRADER_AGENT_ADDRESS env variable in the file .trader.env with that address. The corresponding private key needs to be set as the value of the env variable TRADER_P_KEY in the same file

• Another Gnosis address #2 is associated with the market creator agent, and you need to associate the CREATOR_AGENT_ADDRESS env variable in the file .creator.env with that address). The corresponding private key needs to be set as the value of the env variable CREATOR_P_KEY in the same file

Other variables that need to be filled in with your own values are:

• OPENAI_API_KEY and RPC in the file .creator.env
• OMEN_CREATORS and RPC in the file .trader.env

Finally, the agents run as part of autonomous services that are represented on-chain in the Autonolas protocol by Safe multisigs, corresponding to the variables SAFE_CONTRACT_ADDRESS in the files .trader.env and .creator.env. For both of the services, follow the next steps to compute the Safe address corresponding to your agent addresses:

• Visit https://registry.olas.network/services/mint and connect to the Gnosis network. For this demo, we recommend connecting using a wallet with a Gnosis EOA account that you own.
• In the field "Owner address" input a Gnosis address for which you will be able to sign later using a supported wallet. If you want to use the address you're connected to click on "Prefill Address".
• Click on "Generate Hash & File" and enter the value bafybeicgjqgkf2wv54rows3lw4qxnaqnxannumuonh6vahb3ldlzu7cyhi
• In the field "Canonical agent Ids" enter the number 12
• In the field "No. of slots to canonical agent Ids" enter the number 1
• In the field "Cost of agent instance bond (wei)" enter the number 10000000000000000
• In the field "Threshold" enter the number 1
• Press the "Submit" button. Your wallet will ask you to approve the transaction. Once the transaction is settled, you should see a message indicating that the service NFT has been minted successfully. You should also see that the service is in Pre-Registration state.

• Next, you can navigate to https://registry.olas.network/services#my-services, select your service and go through the steps:
  1. Activate registration
  2. Register agents: here, you must use the value that you set previously for TRADER_AGENT_ADDRESS.
  3. This is the last step. A transaction for the safe's deployment is already prepared and needs to be executed.
• After completing the process you will be able to retrieve the value for the variable SAFE_CONTRACT_ADDRESS from the field "Safe contract address" as shown in an example below

Finally, run the demo script:

./demo.sh

Two folders will be generated, one for each service. Among other contents, the logs are accessible within the folders. For example, creator_service/abci_build/persistent_data/logs contains the creator service's logs.

Keep in ming that the script runs some docker containers in the background. In order to stop all the containers, please run on a separate terminal:

docker rm -f -v marketmaker_abci_0 marketmaker_tm_0 trader_abci_0 trader_tm_0

When you run the script for a second time, it reuses the existing build, recreating the previous state. In case you want to re-create your build, then before running the script execute:

sudo rm -rf creator_service/abci_build && sudo rm -rf trader_service/abci_build
