]About this contract
overview
StdToken is the TRC20 contract behind STD Token (STD) on Tron, deployed from TQtrATsofeZfB1WDrD7zpL37Vita3B7Kcm on Mar 4, 2022. It has been called 28.62K times.
This contract is not source-verified, so only its on-chain bytecode and ABI are available. Read calls still run live against the node. Write calls require a signed wallet transaction — wallet support is coming soon.
