Is my business opportunity legal?

In a previous job, I made a lot of connections with international business owners. Many of them own/operate large fintech, development, or crypto companies that find it difficult to obtain access to US banking services & dollars (many US banks deem these industries as ‘high-risk’, but reserve accounts for only major corporations - not impossible to get an account, but very hard).

Many of my clients will ask if I can provide US Dollar settlement to support their business operations. With the opportunity, I’ve filed a DE entity, registered as an MSB via FinCEN, and crafted a very stringent KYC/AML policies to govern who my business will settle transactions for (only ones who meet proper US compliance) and when.

Aside from my MSB registration, assuming all proper KYC/AML is conducted, is there anything more I should look into to protect the business legally?

*The major US banking partners I am using to support the settlement business are comfortable with the flow of funds & my current entity structure.
