Smarty top-up — FAQ
How do I top up a Smarty number with Bitcoin?
Open the Smarty page on Neloxi, enter the destination phone number, pick an amount between £5 and £50, choose Bitcoin or Lightning, and pay the invoice. Lightning settles in seconds. On-chain Bitcoin takes 10–60 minutes for 1 confirmation. Credit lands on the line right after the payment confirms.
Can I top up Smarty with Monero?
Yes. Monero confirmation takes about 1 minute. Once confirmed, the recharge is forwarded to Smarty via a wholesale aggregator. Monero is the recommended option if you want the top-up to be unlinkable to your other crypto activity.
Does Smarty need any account or ID for the recharge?
No. From the Smarty side, the recharge looks identical to a kiosk scratch card sale. They only see the phone number and the amount. Neloxi never collects buyer data, and Smarty never receives any.
What if I send a top-up to a number that doesn't exist on Smarty?
Smarty's API rejects the recharge, and Neloxi automatically refunds the full amount in the same cryptocurrency to the refund address you provided at checkout. No support ticket required.
What are the available Smarty denominations?
Smarty accepts top-ups between £5 and £50. Neloxi mirrors the operator's denomination set — we don't add or remove amounts.
How long does the Smarty recharge take?
End-to-end: under 60 seconds with Lightning, Solana, or Monero; about 1 minute with USDT-TRC20; 10–60 minutes with on-chain Bitcoin (1 confirmation required). The operator side itself is near-instant once we forward the order.
