Smart contracts include an event listener that listens for transaction events between the main account and sub-accounts. Once a transaction event is detected, the smart contract judges whether a balance transfer between sub-accounts is needed according to pre-set rules. If the conditions are met, the smart contract will transfer the corresponding balance from the source sub-account to the target sub-account. Additionally, to ensure the security and traceability of the transaction, the smart contract will also record the transfer process on the blockchain. This enables automation of balance transfers between sub-accounts through event handling."}]}],"pr":"dcab565b5260f48d0b1f3fae19e1f2988c85a2bc64b4fd9b5a1029e6bcfd80c1"}
