Web3 Function Task created from Smart Contract

There are three ways to create Web3 Function Tasks:

1. Using the UI
2. Using the Automate-SDK
3. Using a smart contract

This project demonstrates creating a Web3 Function task directly from a Smart Contract (3rd option).
This behaviour is ideal for factory contracts as everything takes place on-chain.

There are three ways to handle fee payment:

1. Using 1Balance
   • This will fund all tasks you create on any network
2. Sync fee payment with native tokens in the target contract
   • This will only fund tasks interacting with that one contract
3. Sync fee payment with native tokens in the dedicated message sender
   • This will fund all your tasks on that network

Contracts and tests

• Oracle1Balance
  fee payment using 1Balance
• OracleSyncFee
  fee payment using native tokens in the contract

Implementation

Implementation is as simple as inheriting from AutomateTaskCreator and calling _createTask with the appropriate arguments. If you'd like to use sync fee payment, ensure the contract is funded and then, in your automated function, transfer the fee using _getFeeDetails and _transfer.

Warning

Ensure this function is using the onlyDedicatedMsgSender modifier, otherwise anyone will be able to call it and maliciously transfer a fee to themselves.

Note

Ensure the contract itself is whitelisted and not the deployer (EOA)

Quick Start

1. Install dependencies

   yarn install
