Scenario Tests

# Test: User attempts to withdraw below minimum
# Expected: Transaction reverts with "below minimum" error

# Test: Withdrawal at minimum amount succeeds
# Expected: Withdrawal completes

# Test: Admin updates minimum, existing deposits above new minimum allowed
# Expected: Existing deposits unaffected

# Test: Admin updates minimum upward, new deposits validate against new minimum
# Expected: Deposits below new minimum revert

# Expected: Capacity alert events emitted at thresholds

# Test: Query remaining capacity at various fill levels
# Expected: Accurate remaining count at each level

Integration Tests

# Test: Circuit verifies attestation not in revocation set
# Expected: Valid proof for non-revoked attestation

# Test: Circuit rejects attestation in revocation set
# Expected: Invalid proof after revocation

# Test: Revocation root updates trigger circuit refresh
# Expected: New proofs use updated root

Manual Testing Checklist

• Deploy to Soroban sandbox
• Test all slashing offense types
• Verify minimum withdrawal prevents dust
• Confirm capacity alerts at 85% and 95%
• Test revocation in production circuit
• Verify events are properly indexed
• Audit gas costs for each operation
• Load test with concurrent operations
• Verify state consistency across operations
