Crypto cards and neobanks

TRON energy for crypto cards and neobanks

A crypto card or neobank holds user balances in USDT and moves funds between its own wallets and users. Those internal moves are ordinary transfers, and each one needs energy.

  1. 1

    A balance is topped up or spent

    A user funds their account in USDT, or a card payment is settled, and the service moves USDT between wallets.

  2. 2

    Energy for the movement

    Each transfer between the service's wallets is sent from one of them, so energy has to be delivered to that sender.

  3. 3

    The destination holds USDT

    Moving funds between the service's own funded wallets is the cheaper case, 65,000 Energy per transfer.

A trade-off, not a recommendation. More settlements cost more energy but tie up less USDT waiting; fewer do the reverse. Settlement wallets are your own and hold USDT, so each transfer is the cheaper case.

Where energy is spent

Funding and settlement
Consolidating user top-ups and settling card volume are both plain USDT transfers between known wallets.
A set of wallets to keep ready
Each sending wallet needs energy. Rules keep several of them topped up instead of one by hand.
Known recipients
Because the service controls the destination wallets, it knows their balance and can plan the energy figure.

Card issuing, licensing and settlement with card networks are outside this page. It covers only the USDT transfers on TRON.

Questions

Why are transfers between our own wallets cheaper?

Because the destination already holds USDT. Sending to an address with a non-zero balance takes about half the energy of sending to one with none.

Can several wallets be kept ready?

Yes. Each address you watch is topped up on its own rule, so several hot wallets stay ready together.
