On the 7th, China Southern Power Grid Corporation announced that the Shenzhen Power Supply Bureau of Southern Power Grid has automatically completed the rental payment to Southern Power Grid Industry and Finance Group's financing leasing company in the form of digital RMB during non working hours through smart contract technology, with a total transaction amount exceeding 57 million yuan (RMB, the same below). This marks the official launch of the first "digital RMB+smart contract" rental payment service in the Guangdong Hong Kong Macao Greater Bay Area. Smart contracts are digital protocols that automatically execute based on preset rules, enabling precise payment in a fully closed-loop system with "timed, fixed, and targeted" features. This business integration of digital RMB's core advantages of security, controllability, efficiency, convenience, and low cost, combined with the automation and tamper proof technical features of smart contracts, has achieved unmanned and automatic execution of the entire non working period fund settlement process, greatly improving the efficiency of enterprise fund payment and further strengthening the security control level of the entire fund process. In the past, during the peak period of rent payments at the end of each season, financial personnel had to manually initiate payment applications and go through multiple levels of approval before settlement could be completed. ”According to Zhong Liyun, a financial staff member of Shenzhen Power Supply Bureau, now by pre setting core elements such as payment time, amount, and receiving account through smart contracts, the system can automatically complete the entire process settlement at the agreed time, effectively freeing financial personnel from high-frequency repetitive transactions. Wang Ruoxuan, a business personnel of Southern Power Grid Financial Leasing Company, said that the financial leasing business has multiple links and entities, which is highly compatible with the "digital RMB+smart contract" model. This model not only streamlines the settlement process and improves business efficiency, but also strengthens the financial security defense line through the rigid constraints of technology. It is reported that as of now, China Southern Power Grid Corporation has promoted the pilot of digital RMB in 24 scenarios, with a cumulative transaction scale exceeding 65 billion yuan. In the future, Southern Power Grid Corporation will promote the application of "digital RMB+smart contracts" in the system and upstream and downstream enterprises, promoting the deep integration of financial intelligence and industrial digitization.
