TRC20 Transfer Energy: Why 64,400 Energy?

You often see "64,400 energy per USDT transfer"—where does that number come from, and why does it sometimes become 130,500?

Where 64,400 comes from

USDT is a TRC20 contract on TRON. Calling its transfer method executes contract logic, which the chain converts into energy cost. For a recipient that already holds USDT, a standard transfer costs ~64,400 energy.

Why 130,500 sometimes

When the recipient has never held USDT, the contract must initialize a balance record—extra state writes push the cost to ~130,500 energy. That's why "first transfer is more expensive".

How to prepare energy

Budget 64,400 energy per transfer, and leave headroom for recipients without USDT (or use a platform's one-click estimation). For batch transfers, estimate total = transfers × per-transfer energy.
