let result = await mcbuild.tx(params);

example

// donation build tx 
app.route('/donate-build').post(async function(req,res){
    let err={};if(typeof req.body.account=="undefined"){err.transaction="error";err.message="action did not receive an account";res.send(JSON.stringify(err));}
    
    // verify amount param was passed
    if(typeof req.query.amount=="undefined"){err.transaction="error";
      err.message = "action did not receive an amount to send";
      res.send(JSON.stringify(err));
    }

    // create instructions
    let lamports = req.query.amount * 1000000000;
    let from = new PublicKey(req.body.account);
    let to = new PublicKey("GUFxwDrsLzSQ27xxTVe4y9BARZ6cENWmjzwe8XPy7AKu");
    let donateIx = SystemProgram.transfer({fromPubkey:from, lamports:lamports, toPubkey:to});

    // build transaction
    let _tx_ = {};
    _tx_.rpc = rpc;                     // string : required
