Errors
Exact TRON error codes explained in plain language — what OUT_OF_ENERGY, REVERT and the others actually mean.
Why USDT TRC20 Transfers Fail With "Out of Energy"
OUT_OF_ENERGY is the single most common reason a USDT transfer fails on TRON, and it has nothing to do with your USDT balance.
USDT TRC20 Transaction Status: REVERT
A REVERT means the transaction reached the network and was executed, but the USDT smart contract itself rejected it mid-call.
USDT TRC20 Transaction Status: OUT_OF_TIME
OUT_OF_TIME is a rarer failure state than OUT_OF_ENERGY or REVERT, tied to how long the network took to execute the call rather than resources or contract logic.
USDT TRC20 Error: Bandwidth Limit Reached
Bandwidth is TRON's second resource, separate from Energy, and running out of it produces a different failure than an Energy shortage.
USDT TRC20 Transaction Status: Expired
Every TRON transaction carries a built-in expiration timestamp, and missing that window produces a distinct failure from a simple pending state.
USDT TRC20 Error: Duplicate Transaction
A duplicate transaction error means the network already has this exact transaction recorded — which is usually good news, not bad news.
USDT TRC20 Error: Contract Validate Error
This error happens earlier than OUT_OF_ENERGY or REVERT — the network rejects the transaction before it even attempts to execute the contract call.
