# Manual Validation

Accelchain offers manual validation capabilities similar to Remix IDE, enabling developers to interact with a blockchain instance of the deployed contract for meticulous testing. By clicking 'run' in the Accelchain IDE, users access a blockchain environment where they can call functions, examine existing storage variable values, and observe changes in values implemented through function calls.

#### **Function Execution:**&#x20;

* Constant/pure functions can be executed without creating new transactions, providing values stored in the contract.&#x20;
* Non-payable functions create transactions without Ether acceptance, incurring gas costs.
* Payable functions enable transactions that accept a specified value.

#### **Input Parameters:**

* String parameters do not require wrapping, and valid inputs are separated by commas.
