With "What is a wallet address?" in mind, one rule covers most of it: every detail must line up before coins are sent. A coin deposit travels on a public network, and the casino only sees it once that network has confirmed the transfer. The coin, the network it runs on, the address and sometimes a memo all have to match what the payment page shows. Most failed crypto payments come from a mismatch in a single one of those details, and very few can be undone once sent.
Withdrawals run the same route in reverse: the player supplies an address, and the casino sends coins on the network it supports. An address from a wallet or exchange that does not support that network can lose the payment, so the receiving side deserves the same care as the sending one. A small test transfer before a large one costs one extra fee and confirms the whole route, including any tag the receiving account needs.
A transfer is credited after the network has confirmed it a set number of times, and the casino decides how many confirmations it waits for. On a fast network that takes seconds; on a busy or slower one it can take an hour or more. A deposit that shows as sent in the wallet but not yet in the account is usually still collecting confirmations, and the transaction hash lets anyone follow its progress on a public block explorer.
Many coins exist on more than one network, and a casino usually accepts each coin on only one or two of them. The payment page names the network next to the deposit address, and a wallet must send on exactly that network. Coins sent on a different network can arrive at an address the casino does not watch, and recovering them depends entirely on the goodwill and tools of its payment team, when recovery is possible at all.
Common questions
Should a deposit address be typed by hand?
No. Addresses are long and unforgiving, so pasting the full address fresh from the cashier for every deposit is far safer.
Why does the network matter for a coin deposit?
Many coins run on several networks, and a casino accepts each on only one or two; coins sent on another network may reach an address nobody watches.
What is a memo or destination tag for?
Some networks need it to tell the casino which account the coins belong to; without it, the transfer waits for support to match it manually.
Who pays the network fee on a coin transfer?
The sender pays it at the moment of sending, and its size depends on how much demand the network faces right then.
Is a small test transfer worth the extra fee?
Sending a small amount first costs one more fee but confirms the whole route, address and tag included, before a larger sum moves.
