Simplify single contract deployment

[kanej]

Ignition modules provide significant features (e.g. restartable deploys) but for the simplest case of deploying a single contract, it adds the boilerplate of declaring a module. Can we reduce/eliminate the boiler plate?

This is a design task to answer that question.

We need to support both script/test usage and command line usage.

Questions

• How does this interact with module parameters?
• Should we ignore the from field (and just rely on --default-sender)
• How is the moduleId generated?
• Can we rely on the default future id generation for the contract?
• How are libraries to be supported? At the command line?
• How are constructor args to be handled at the command line?
• How does this work with create2?
• How do we handle the tracking, from the user perspective of which contracts have been deployed?

Use Cases

• Deploy a single Hardhat contract with no constructions args from a script/test by name and get back an ethers contract instance
• Deploy a single Hardhat contract with no constructions args from a script/test by name and get back a viem contract instance
• Deploy a single Hardhat contract with constructions args from a script/test by name and get back an ethers contract instance
• Deploy a single Hardhat contract with constructions args from a script/test by name and get back a viem contract instance
• Deploy a single Hardhat contract without constructor args by name from the cli
• Deploy a single Hardhat contract with constructor args by name from the cli
• Deploy a single contract with no constructor via create2 from script/test
• Deploy a single contract resetting the deployment

Approach

From a scripts perspective maybe we enhance the ignition-helpers with a deployContract method:

const myToken = await hre.ignition.deployContract("Token", ["COIN", 10_000], { deploymentId: "my-sepolia-deploy-1" });
console.log(await myToken.getAddress())

This would be the equivalent of:

const { token: myToken } = await hre.ignition.deploy(buildModule("Contract-Token", (m) => m.contract("Token", ["COIN", 10_000])), { deploymentId: "my-sepolia-deploy-1" });
console.log(await myToken.getAddress())

In terms of the command line, perhaps we can leverage module parameters with a required property of constructor-args or something:

npx hardhat ignition deploy-contract MyToken --module-parameters "{\"constructor-args\": [\"COIN\", 10_000]}"
