Transfer Edge

Transfer Edge is an infrastructure service that simplifies transaction processing on blockchains. With Transfer Edge, you no longer need to hold the native currency in your wallet. Just create a transaction, sign it, and broadcast it — we handle the rest.

From a technical standpoint, Transfer Edge functions as a standard blockchain RPC, making integration seamless. All you need to do is update the RPC endpoint in your application and top up your Transatron account. Currently, it supports the Tron blockchain only, but additional chains — starting with Ethereum — will be added soon.

On Tron specifically, Transfer Edge not only processes transactions without requiring TRX, it also makes transacting cheaper. Instead of burning TRX for bandwidth or energy, Transfer Edge supplies the necessary resources to the transaction’s origin address before it reaches the mempool. When the transaction is processed by a validator, it consumes the resources provided by Transatron instead of burning TRX. Unlike other Tron energy providers that require users to pre-order resources for their addresses, Transatron automatically allocates resources when a transaction is broadcast. No pre-ordering, no TRX for bandwidth, and no prior account activation are required.

“Broadcast and forget” — that’s our credo.

Accounts in Transatron​

Transatron operates two types of accounts:

  • Business accounts:

    Best for

    Exchanges, payment gateways, custodial services, and any business operating Transatron at scale.

    Register to obtain a dedicated deposit address (similar to exchanges).
    Check balances and account details either through the Transfer Edge Dashboard or via the GET /api/v1/config endpoint, which returns current TFN/TFU balances, the deposit address, resource pricing, and active-coupon summary in a single response.

  • Address-based accounts:

    Best for

    Individual users transacting via non-custody wallets.

    Auto-created the first time you top up — send TRX or USDT from any Tron address to: TFPzL92nmSxLVVNHoL5cbZ6tjSxfuKUBeD.
    Check balances by adding the TFN and TFU TRC-20 tokens to your wallet and querying them through the Transatron node.

Paying transaction fees with Transatron​

Transatron supports several fee-payment modes:

  1. Internal account payment — requires a registered business account; prepay it (TRX/USDT) and fees are auto-deducted from your TFN/TFU internal balance.
  • Charge in TFN — deposit TRX → credited as TFN; each tx deducts TFN automatically.
  • Charge in TFU — deposit USDT → credited as TFU; each tx deducts TFU automatically.
  1. Instant fee payment — pay the fee right before the main transaction by sending a small fee transaction first.
  • Instant TRX fee payment — send a TRX transfer, then the main transaction.
  • Instant USDT fee payment — send a USDT transfer, then the main transaction.
  1. Coupon payment — requires a registered business account; pay for any transaction with a coupon issued by the business account.
  • The business issues a coupon for a set TFN amount; user includes the coupon code when broadcasting.
  • Required TFN is reserved from the business’s internal account until the coupon is spent or expires.
  1. Bypass mode
    If no Transatron payment method applies, Transatron simply forwards the transaction on-chain; TRON charges fees per its normal rules (staked resources or TRX burn).
info

All payment methods require broadcasting via the Transatron node. Broadcasting through other TRON nodes will not trigger Transatron’s resource delegation/charging logic.

Internal account payments​

This is the cheapest option, but it requires a registered business account and a prepaid balance, plus some operational workflows:

  1. Register a business account in the Transfer Edge Dashboard and obtain its dedicated deposit address.
  2. Deposit TRX or USDT to that address to receive TFN or TFU on your Transatron internal account.
  3. Broadcast your transaction as usual (via the Transatron node’s /wallet/broadcasttransaction).
  • If sufficient TFN/TFU is available, Transatron deducts the fee automatically.
  • If not, Transatron bypasses the fee logic and forwards the transaction (TRON will then charge per normal).
  1. Monitor & top up your TFN/TFU balance as needed.

Instant fee payments​

Create two transactions:

  1. The fee payment transaction (TRX or USDT transfer).
  2. The main user transaction.

Broadcast them sequentially to /wallet/broadcasttransaction via the Transatron node. Transatron detects the first as an instant fee payment, waits for the second, allocates resources to the user’s address, and then broadcasts both together.

warning

If the instant fee payment transaction fails, the main transaction will not be broadcast to the TRON node, so you can safely retry the entire sequence.

Coupon payments (business)​

Designed for businesses that want to sponsor user fees:

  1. The business tops up its internal account (TFN/TFU) via its dedicated deposit address.
  2. The business generates a coupon with a spending limit in TFN (e.g., 15 TFN ≈ one USDT transfer).
  3. The business gives the coupon code to the user.
  4. The user includes the coupon code when broadcasting the transaction.
  5. Transatron covers the transaction resources—the user pays nothing.
  6. After spending, any unspent TFN is refunded to the business.
  • Example: If a USDT transfer costs 6.5 TFN and the coupon is 15 TFN, then 8.5 TFN is refunded.

Bypass mode​

If no fee mode applies (no instant payment, no internal balance, no coupon), Transatron forwards the transaction to the blockchain as is. The TRON protocol then charges fees per its own logic (staked resources or TRX burn). Transatron does not return errors for this case.
