Create Tasks

Overview

The Othentic CLI allows you to define different Tasks to be performed by Operators. This guide covers the commands needed to define these tasks via Task Definitions.

Prerequisites

• Othentic CLI installed

• Access to AVS Governance multisig owner account

• Attestation Center contract address of the AVS

1

Create Tasks

Run the following command:

otcli network create-task-definition

Pass --browser-sign flag to connect your wallet and sign using a web browser UI.

Follow these steps when prompted:

• Provide the private key of the multi-sig address.

• Enter the Attestation Center contract address.

• Enter all the Task details

  • Task Name

  • Base Rewards (e.g. 0.001 ether; default: 0)

    • Attester rewards

    • Performer rewards

    • Aggregator rewards

  • Minimum voting power

  • Restricted attester IDs

  • Max number of Attesters

  • Expiry block – When the task expires (leave blank for never)

2

Implement Task Execution Service Logic

Write the logic that the Performer will execute.

In your implementation, make sure to execute the task based on the appropriate Task Definition ID.

curl -X POST http://localhost:4003/task/execute \
  -H "Content-Type: application/json" \
  -d '{
        "taskDefinitionId": 123
      }'

3

Implement Task Validation Service Logic

Write the logic that the Attester will execute.

In your implementation, make sure to validate the task based on the appropriate Task Definition ID received as part of the `sendTask` RPC request.

{
  "taskDefinitionId": 123,
  "proofOfTask": "abcs",
  "data": "0x1232",
  "performer": "0x1234567890abcdef1234567890abcdef12345678"
}

Verify Tasks creation

Refer to the following Task specific methods in the Attestation center to get details about the tasks created. These methods allow you to query Task specific data like Minimum Voting Power, Restricted Operator Set etc.

Using scripts

New Task Definitions are created on-chain via the AttestationCenter smart contract. To create a task definition, call createNewTaskDefinition as shown in the example below:

Ethers

const attestationCenter = new ethers.Contract(
  ATTESTATION_CENTER_ADDRESS,
  ['function createNewTaskDefinition(string,(uint256,uint256,uint256,uint256,uint256,uint256,uint256[])) external']
);

const tx = await attestationCenter.createNewTaskDefinition(
  "Example Task",             // Human-readable name
  {             
  ethers.MaxUint256,          // Never expires
  ethers.parseEther('0.01'),  // Reward for attestation
  ethers.parseEther('0.1'),   // Reward for performer
  ethers.parseEther('0.005'), // Reward for aggregation
  0,                          // Disable disputes
  0,                          // Minimum Voting Power
  []                          // Restricted Operator Set 
  }                          
);

await tx.wait();
