Not every smart contract is compatible with **Eth-Bundler**. To use the platform, your contract must include an `enableTrading` function (or a similar functions). For reference, you can download a sample of a compatible contract here:

{% file src="/files/JAiQWRzmaLQH6lPyqH5X" %}

<pre class="language-solidity"><code class="lang-solidity">// solidity

function enableTrading() external onlyOwner()
function openTrading() external onlyOwner()
function startTrading() external onlyOwner()
function openTrade() external onlyOwner()
function startTrade() external onlyOwner()

<strong>/* if you have one of these function or similar one, then all good. */
</strong></code></pre>
