WHAT IT DOES

What wrap_trx does on Justlend

AI agents use wrap_trx to commit financial operations through Justlend, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why wrap_trx is rated Critical

This tool moves native TRX tokens into a wrapped contract, committing real financial assets (TRX) to a smart contract operation. While it is a 1:1 wrap and not a trade, it involves transferring/locking cryptocurrency assets, which constitutes a financial transaction. Misuse could result in loss of funds if sent to wrong contract or in unintended amounts.
