Required things for DTV-VISA from the Thai embassy site.
"Evidence of sufficient financial assets (at least 500,000 THB) which can take the form of:
-6-month official bank statement (crypto or other investment statements are not accepted)
-Payslips
-Sponsorship letters"
I'm curious about the last two. 
Can a sponsorship letter be from the (homeland) company that you work for? 
"Payslips"; I understand that they could be used as support for the fact that you are employed, but they are listed under "evidence of sufficient financial assets". Or this is perhaps at a later stage, similar to the 65k thing for non-O?
TLDR : Answer Summary
The requirements for a DTV visa include evidence of sufficient financial assets, specifically at least 500,000 THB. Acceptable documentation includes a 6-month official bank statement, payslips, and sponsorship letters. Clarification is needed regarding the use of sponsorship letters, as they can typically only be provided by family members for dependents applying under a DTV visa. Payslips serve as proof of employment but also contribute to demonstrating sufficient financial support while staying in Thailand.
