What the Freelancer needs to start the work
Is this a new build or modernization of an existing system?
If existing: what is the current stack and Java version, and how large is the codebase?
What does the product do and who are the end users (retail, institutional, internal)?
Which blockchain, protocols, and external systems does it need to work with (custody, exchanges, payment rails, core banking APIs)?
What regulatory and compliance requirements apply (licensing, KYC/AML, jurisdiction), and what is the expected timeline?
