BOT fulfills its social responsibility as a state-owned bank, actively investing in the development of various social public welfare trust products with its professional and rich experience, demonstrating its commitment to current affairs issues by providing special trusts to address the needs of socially vulnerable people and constructing a social security net.

BOT is committed to cross-industry cooperation with government agencies and social welfare organizations, helping childless elderly people transform through the "Seedless Watermelon Trust Service Project", enabling them to enjoy their senior years with support. The Taichung City Trust Service Program for Persons with Disabilities is collaboration between the government, social welfare institutions, and BOT. The program uses trust planning to care for individuals with disabilities and provides trust services that meet the needs of vulnerable groups in society, such as those with disabilities, elderly individuals living alone, families with significant changes, or those with insufficient economic capacity. The program actively collaborates with county and city governments to serve cases of socially disadvantaged individuals and plays a stabilizing role in society as BOT implements social welfare and fulfills its corporate social responsibility through trusts.

To protect investor and consumer rights of the young and the elderly, and to truly understand customer needs, BOT adds a task reminder to ask fraud prevention questions and control mechanism for young customers aged 18-20 (excluding 20) at the counter; sets a requirement to complete "Notice and questions to be asked in order to understand the needs of elderly customers aged 65 and above" when handling care trusts; asks questions to customers aged 85 and above at the counter before they trade investment funds and other commodities; and implements a control mechanism for elderly customers who trade investment funds at the counter or online. In addition, to increase the protection of vulnerable investors' rights and interests when they purchase financial products, customers aged 65 and above, with an education level of junior high school or below, or with a National Health Insurance major illness certificate, are required to sign a declaration on the channel reward disclosure document when handling fund subscription transactions so as to truly understand the potential risks of their investments, which also ensures that trust fees and the following risks are clearly delivered, allowing BOT to strengthen protection of consumer rights.

BOT is committed to providing trust planning services in innovative and integrated ways that benefit public welfare. For example, by combining elderly care trusts with public welfare in innovative promotion methods, we aim to create public welfare in elderly care trusts; we have launched the "Donating Invoices for Public Welfare" campaign, working together with customers and social welfare groups to create a win-win. Furthermore, the bank collaborates with local governments and social welfare organizations to take care of vulnerable groups who have long been overlooked but urgently need help through projects such as "Bravely move forward in life without hindrance. A BOT Trust is your companion with love". The promotional goals of such campaigns are "caring for public welfare", "protecting vulnerable groups", and "meeting customer needs" to put the spirit of inclusive finance into practice.
