Questions, answered
How does pay-per-solve work?
You pay only when a solve succeeds. Failed solves never hit your balance. Your balance never expires and is non-refundable.
Are there any subscriptions or monthly fees?
No. NSLSolver is fully pay-as-you-go. You add funds with crypto, and we deduct per successful solve at the published per-1,000 rate.
What payment methods do you accept?
USDT (ERC20 and TRC20), USDC, ETH, BTC, LTC, TRX, and SOL via OxaPay. Minimum deposit is $10.
Do volume bonuses apply automatically?
Yes. Add $25+ in a single deposit and the matching bonus credit is added immediately. Bonuses do not stack across smaller deposits.
Can I get a refund if I don't use my balance?
All deposits are final and non-refundable. Balance remains in your account indefinitely until you use it.
