# Balance and top-ups

> How the prepaid balance works: coins and networks accepted, minimum and maximum, confirmations, what happens when a payment is short or late, and refunds.

Servers are paid from a balance in US dollars that you fund in cryptocurrency. Nothing is charged automatically to anything outside that balance: no card on file, no invoice sent, no debt.

## Coins and networks

| Coin | Network | Note |
| --- | --- | --- |
| Bitcoin | Bitcoin | on-chain only, no Lightning |
| Monero | Monero | private by default |
| Ethereum | ERC-20 | mainnet only, no L2 |
| Tether | ERC-20 · TRC-20 | ERC-20 or TRC-20; TRC-20 is cheaper and faster |
| Litecoin | Litecoin | native network |
| TRON | TRON | native network |
| Solana | Solana | native network |

The top-up page tags the cheapest, fastest and most private option for the amount you enter. Send on the network the invoice names: a token sent on another network is not seen by our processor and cannot be recovered by us.

## Minimum, maximum, rate

Minimum $40 per top-up (the processor's floor, not ours), maximum $20,000 per invoice; several invoices may be open at once. The exchange rate is fixed when the invoice is created and holds for the validity window printed on it. After the window, a payment is credited at the rate of the moment it is seen.

## Confirmations

The invoice page shows when the transaction is seen on the network, then how many confirmations remain, then the credit. Typical times are printed on the top-up page next to each coin; TRON and Solana usually settle in a minute or two, Bitcoin in about an hour. You can close the page: the balance updates without it.

## Short, late or wrong

- **Short.** An amount below the invoice is credited at its value once confirmed. Top up the difference with a new invoice.
- **Late.** Credited at the rate of the day it arrives.
- **Wrong network or wrong coin.** Not seen by the processor; open a ticket with the transaction hash and we will look, without promising.

## Ledger

[Billing](https://dedigpu.com/app/billing) lists every top-up, every term charged, every credit, with the balance after each line. The same data is in `/api/v1/me`.

## Refunds

Unused balance is refundable to the address it came from, in the same coin, less network fees, within seven days of the request from a ticket. Rent already charged for a term is not refundable except as the [SLA](https://dedigpu.com/legal/sla) provides.
