We recommend using pnpm as a package manager (but you can of course use a package manager of your choice):

pnpm install

This project supports both hardhat and forge compilation. By default, the compile command will execute both:

pnpm compile

If you prefer one over the other, you can use the tooling-specific commands:

pnpm compile:forge
pnpm compile:hardhat

Or adjust the package.json to for example remove forge build:

- "compile": "$npm_execpath run compile:forge && $npm_execpath run compile:hardhat",
- "compile:forge": "forge build",
- "compile:hardhat": "hardhat compile",
+ "compile": "hardhat compile"

Similarly to the contract compilation, we support both hardhat and forge tests. By default, the test command will execute both:

pnpm test

If you prefer one over the other, you can use the tooling-specific commands:

pnpm test:forge
pnpm test:hardhat

Or adjust the package.json to for example remove hardhat tests:

- "test": "$npm_execpath test:forge && $npm_execpath test:hardhat",
- "test:forge": "forge test",
- "test:hardhat": "$npm_execpath hardhat test"
+ "test": "forge test"

Set up deployer wallet/account:

• Rename .env.example -> .env
• Choose your preferred means of setting up your deployer wallet/account:

MNEMONIC="test test test test test test test test test test test junk"
or...
PRIVATE_KEY="0xabc...def"

• Fund this address with the corresponding chain's native tokens you want to deploy to.

To deploy your contracts to your desired blockchains, run the following command in your project's folder:

npx hardhat run deploy/DEPLOY_SCRIPT.ts

To deploy Layer Zero contracts, run the following command:

npx hardhat lz:deploy

More information about available CLI arguments can be found using the --help flag:

npx hardhat lz:deploy --help
