Enclave Smart Contracts

Importing the contracts, interfaces or types

To install, run

pnpm add @enclave-e3/contracts

If writing a new E3 program, you can import the necessary interfaces by writing something similar to:

import {
    IE3Program,
} from "@enclave-e3/contracts/contracts/interfaces/IE3Program.sol";

contract MockE3Program is IE3Program {...}

Check out the E3 mock for an example

To deploy

pnpm deploy --network [network]

This will add the deployment information to the ./ignition/deployments directory, as well as to the deployed_contracts.json file.

Be sure to configure your desired network in hardhat.config.ts before deploying.

Localhost deployment

If you are running Enclave locally, you can first start a local hardhat (or Anvil) node, then deploy the contracts using the following commands:

pnpm hardhat node
pnpm clean:deployments
pnpm deploy:mocks --network localhost

This will ensure that you are a local node running, as well as that there are no conflicting deployments stored in localhost.

Configuration

Using Environment Variables (Development)

For development, you can set your private key in a .env file:

# .env
PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Using Hardhat Configuration Variables (Production)

For production, it's recommended to use Hardhat's configuration variables system:

# Set your configuration variable (securely stored)
npx hardhat vars set PRIVATE_KEY

Then update hardhat.config.ts to use configuration variables:

import { vars } from "hardhat/config";

const privateKey = vars.get("PRIVATE_KEY", "");

Registering a Ciphernode

The tasks use the first signer configured in your Hardhat network configuration.

To add a ciphernode to the registry:

pnpm ciphernode:add --network [network]

Options:

• --license-bond-amount: Amount of ENCL to bond (default: 1000 ENCL)
• --ticket-amount: Amount of USDC for tickets (default: 1000 USDC)

For testing/development, you can also use the admin task to register any ciphernode address:

pnpm ciphernode:admin-add --network localhost --ciphernode-address [address]

To request a new committee, run

pnpm run hardhat committee:new --network [network]

To publish the public key of a committee, run

pnpm run hardhat --network [network] committee:publish --e3-id [e3-id] --nodes [node address],
[node address] --public-key [publickey]

To activate an E3, run

pnpm run hardhat --network [network] e3:activate --e3-id [e3-id]

To publish an input for an active E3, run

pnpm run hardhat --network [network] e3:publishInput --e3-id [e3-id] --data [input data]
