6. The company's legal secretary can be provided by the agency

the advantages of registering Singapore Foundation:

(2) as long as there is no cash and surplus at the end of the year, the foundation does not need to pay tax. It's a zero tax return

therefore, the Singapore foundation is the preferred entity for issuing tokens for financing. It is also an organization with credibility in the world. The supporting legal documents issued by Singapore lawyers guarantee the non securities nature of the token issued by the project, and file the project with the government in the name of lawyers

2. Legal compliance: Singapore lawyers shall issue supporting legal documents to guarantee the non securities nature of the token issued by the project (audit white paper), and file the project with the government in the name of lawyers

If you plan to operate the project for a long time or prepare to issue currency, you must register a compliant foundation. Of course, the fee is a little higher, However, it has laid a good foundation for the later operation, and the most direct impact is the price of the legal opinion issued by the lawyer. The price difference of one of the items is enough for you to re register a foundation, so you must ask clearly when you register. Don't be greedy for cheap, so as not to cause trouble in the future
