Combining transactions in front-end

DevFracca's question

Based on this response I'm assuming there's no way to get an optin prompt to occur from the Reach code in an atomc txn with a pay and delete? In the system I'm building the user has to first optin using await this.reach.transfer(this.acc, this.acc, this.reach.bigNumberify(0), assetID); from the frontend, then they have to sign a separate txn for the pay and delete actions.

I'm getting some complaints that this process is very slow compared to the non smart contract solutions that other have built. Combining all of these txns into one would save a lot of time.

const ctcInfo = JSON.parse(chosenAppID);
      const ctc = this.acc.contract(backend, ctcInfo);
      const interact = {
        showBuyInfo: async (assetID, price) => {
          console.log(`AssetID: ${assetID} and Price: ${price}`);
          this.modalMsg = "Awaiting optin to asset..."
          await this.GetAssetURL(assetID);
          await this.reach.transfer(this.acc, this.acc, this.reach.bigNumberify(0), assetID); // optin
          this.modalMsg = "Awaiting payment and smart contract deletion..."
        }
      };
      await backend.Buyer(ctc, interact);

Trying something like this which doesn't seem to be allowed in the rsh

Buyer.pay(0, NFT).to(Buyer);

Correct, we do not currently have a way of exposing direct atomic group construction to frontends.
