-### Enabling Hardhat Node
-If you need to interact with a local Hardhat node for transaction processing, make sure to add the following to your `.env` file:
+### Hardhat protocol tests
 
-```
-HARDHAT_URL=http://hardhat
-HARDHAT_PORT=8545
-COMPOSE_PROFILES=hardhat
-```
-
-This will enable the Hardhat service when running `genlayer up`.
-
-### Disabling Hardhat Node
-If you need to disable the Hardhat node, make sure to remove the following from your `.env` file:
-
-```
-HARDHAT_URL=
-HARDHAT_PORT=
-COMPOSE_PROFILES=
-```
-
-This will disable the Hardhat service when running `genlayer up`.
+Studio transaction processing no longer depends on a separate Hardhat node.
+The contracts under `hardhat/` remain a protocol-parity test harness and can
+be tested directly from that directory.
 
 ## 🚀 Key Features
 * 🖥️ **Test Locally:** Developers can test Intelligent Contracts in a local environment, replicating the GenLayer network without the need for deployment. This speeds up the development cycle and reduces the risk of errors in the live environment.
