What are the limits and in what order is validation applied?

Validation runs in this order. If a step fails, processing stops and you are shown the failed step.

1. File structure — column names, file size, row count, mandatory columns present.
2. Row symbols — characters, format, decimal precision.
3. Currency — single payout currency across all rows.
4. Network codes — valid for the currency where applicable.
5. Minimum withdrawal amount per row.
6. Balance, withdrawal limits, and any active restrictions (for example, a post-fiat-deposit hold).
