    • What is TronCastle?

      TronCastle is a project developed in two phases. Phase #1 features the Telegram bot @TronCastleBot, allowing users to quickly purchase Tron energy by sending TRX. This bot is already operational and has successfully sold millions of Tron energy units. Phase #2, called TronCastle for Sellers, is already in Beta and allows anyone to join TronCastle for automated energy selling.

    • How do I purchase energy via the bot?

      TronCastle offers two payment options:

      1. Pay-per-invoice: Generate an invoice in @TronCastleBot, send TRX to the provided wallet address, and wait for transaction confirmation (typically 3-5 seconds).

      2. Deposit balance: Use /deposit [AMOUNT] to fund your account balance. This allows instant energy purchases using /buy command and via API without waiting for blockchain confirmations.

    • How can I optimize my energy purchase time?

      Default @TronCastleBot ordering process checks for your wallet balance and recipient wallet balance to calculate the amount of energy you need to complete the USDT transfer without burning TRX. This is very useful for people who use TronCastle bot from time to time, but it can be too time consuming for people who use TronCastle bot every day. For experienced customers, the bot provides a shortcut to purchase energy. To optimize your energy purchase time, use the /buy command. This command allows you to purchase energy for your wallet address without going throug the multiple steps of the default ordering process.

    • What is the TronCastle for Sellers?

      TronCastle for Sellers (Phase #2) connects energy providers (people who have staked their TRX) with energy consumers, via TronCastle platform. Become energy seller and boost your staking APY here.

    • What are the benefits of purchasing energy?

      In the Tron blockchain, you can send USDT either by burning TRX or by using energy. Purchasing energy is significantly more cost-effective. Energy purchases help you save on:

      • USDT transfers
      • Smart contract deployments
      • Token transfers
      • NFT minting
      • DeFi operations

      Energy can be obtained by staking TRX in Tron or by purchasing it from others who have staked their TRX. TronCastleBot provides a quick and easy way to purchase energy from such providers.

    • How is the energy price calculated?

      Energy prices are determined by market demand and TRX staking rewards. We offer competitive rates through our network of verified providers. Also, we provide multiple discount tiers for our customers:

      🪩 Basic
      🥉 Bronze
      🥈 Silver
      🥇 Gold
      💎 Platinum

      Use our Telegram bot to see real-time prices.

    • Is there a minimum purchase amount?

      Yes, the minimum energy purchase is 10,000 Tron energy units to ensure efficient processing.

    • How fast is energy delivered?

      Energy transfers are processed within 3–10 seconds after TRX payment confirmation. We continuously optimize our system to reduce transfer times.

    • How much time do I have to use rented energy?

      Energy is provided to your wallet for 1 hour after purchase. After 1 hour, energy will be removed from your wallet.

    • How can I verify that energy is provided to my wallet?

      Go to tronscan.org and check your wallet status. Tronscan shows "energy" and "bandwidth" balances. If you see the energy, you can spend it instead of burning TRX. Additionally, in the operations section, you should see one or more operations of the "Delegate Resources" type.

    • Is bulk purchasing available?

      Yes, we support large energy purchases and offer special rates for bulk orders. Please contact us for more details.
