Your project should be technically feasible and include a clear integration plan for STON.fi's SDK and APIs. You should also be able to demonstrate the skills or resources needed for execution.
For reference:
- Developer documentation: docs.ston.fi
- SDK reference: docs.ston.fi/developer-section/dex/sdk
In practice, reviewers look for: a clear technical plan, a realistic scope for the milestones you propose, and evidence that you understand STON.fi's mechanics well enough to build on them.
