I tried to reach out to buyanylight team but they aren't ready to disclose the exchange they have in mind, right now what matters the most is the exchange a token or coin wants to list on because liquidity is very important, i think PGpay is the best on OP list
The reason being most of the dealings you are doing with these exchanges (until it is made public) are covered by a Non Disclosure Agreement. Considering which, it is both illegal and unethical to share some information. We hope you understand our stance.
Thank You
