+# DEPLOYER_PRIVATE_KEY is used while deploying contract.
+# On anvil chain the value of it can be empty since we use the prefunded account
+# which comes with anvil chain to deploy contract.
+# NOTE: You don't need to manually change the value of DEPLOYER_PRIVATE_KEY, it should
+# be auto filled when run `yarn generate`.
+# Although `.env` is ignored by git, it's still important that you don't paste your
+# actual account private key and use the generated one.
+# Alchemy rpc URL is used while deploying the contracts to some testnets/mainnets, checkout `foundry.toml` for it's use.
