Deposit validation

Deposit field rejects negatives, more than 2 decimal places, and amounts above the per-tx cap.

User story

As an account holder, I want the deposit form to refuse invalid amounts before submission so I avoid card failures.

Acceptance criteria

  • Negative amounts are blocked
  • More than 2 decimal places are blocked
  • Amounts above $10,000 require approval
  • Valid amount shows the projected new balance

Manual test steps

  1. 1.Open /wallet
  2. 2.Enter -10
  3. 3.Enter 250.123
  4. 4.Enter 12000
  5. 5.Enter 250 and submit

Expected result

Successful 250 deposit increases the balance and posts a 'Deposit posted' toast.

Possible bug risks

  • Floating point: 0.1 + 0.2 ≠ 0.3 in totals
  • Negative sign hidden by CSS but accepted server-side
  • Approval threshold off by one, blocking valid 10,000 deposits
