mcbuild

builds, optimizes, serializes, and encodes a solana transaction for both apps and actions

note

this tx builder requires a Helius RPC as it utilizes the getPriorityFeeEstimate method

import

import mcbuild from './mcbuild.js';

example

// create your instructions and then:

// optimize transaction
const _tx_ = {};
_tx_.rpc = rpc;                       // string : required
_tx_.account = payer;                 // string : required
_tx_.instructions = [instruction];    // array  : required
_tx_.signers = false;                 // array  : default false
_tx_.serialize = false;               // bool   : default false
_tx_.encode = false;                  // bool   : default false
_tx_.table = false;                   // array  : default false
_tx_.tolerance = 1.1;                 // float  : default 1.1    
_tx_.compute = true;                  // bool   : default true
_tx_.fees = true;                     // bool   : default true
_tx_.priority = "Medium";             // string : VeryHigh,High,Medium,Low,Min
const tx = await mcbuild.tx(_tx_);    // mcbuild

// stop for errors
if(typeof tx.logs != "undefined"){
  console.log("error", tx);
  return;
}

try{

  // sign, serialize, and send transaction
  const signed = await provider.signTransaction(tx);
  const signature = await connection.sendRawTransaction(
    signed.serialize(),
    {skipPreflight:true,maxRetries:0}
  );     
  
  // track the status
  // default: 10 checks max for tx confirmation, check in 4 second intervals
  const status = await mcbuild.status(rpc,signature,10,4); 
  console.log("status", status);

}
catch(err){
  console.log("err", err);
