TRON public chain is a decentralized blockchain network implemented based on TRON protocol, performs as the core of TRON ecosystem, launched on Jun 25th 2018. Many things can be done through TRON public chain, including token assets issuing, DAPP deployment and running, stake and vote for gains, assets transferring, Etc.
TRON public chain is one of the most secure public chain systems at present. The reason it is outstanding is that the blockchain runs in a decentralized network environment, in which creation and storage of the data do not rely on specific individuals or organizations, and the data is ensured to be never changed by cryptography.
TRON public chain has better operational efficiency and stability than most public chains due to a well-designed architecture and code.
TRX is the primary currency used in the TRON network. TRX can be used to vote for super representatives and obtain bandwidth. Staking the TRX balance in a wallet gives the user TRON Power (TP), which is used to vote for Super Representatives (SRs).

Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
