Crypto Casino Networks and Memos

A native coin, such as Bitcoin, ETH or TRX, is part of the network it runs on: it pays that network's fees and exists nowhere else in its original form. A token is different. It is a balance recorded by a smart contract on some host chain, and an issuer can deploy the same token on as many chains as it likes. USDT exists on TRON, Ethereum, Solana, TON and several others; USDC on Ethereum, Solana and a long list of Ethereum-compatible chains.

Each of those deployments is its own ledger. USDT on TRON and USDT on Ethereum are both worth a dollar, but a balance on one cannot be read from the other, and moving between them needs an exchange or a bridge. Cashiers label the choice with the token standard of each chain: TRC-20 for TRON, ERC-20 for Ethereum, BEP-20 for BNB Smart Chain.

Not every copy comes from the original issuer. The USDT most wallets send over BNB Smart Chain is a wrapped version issued by a third party, and bridged USDC, often labeled USDC.e, is a different contract from the USDC its issuer mints on the same chain. Issuers also leave networks: USDT lost official support on several older chains on 1 September 2025, and USDC on TRON lost its issuer's support in 2025. A cashier still offering one of those combinations is showing an outdated list.

The prefix is the quickest check that an address belongs to the network you meant to use: a TRON address cannot be mistaken for a Bitcoin one. The check fails in one large family, where every Ethereum-compatible chain uses the same 0x form, so for those coins only the network name printed beside the address separates one copy from another.

Three coins on these pages are usually deposited with a second piece of information: XRP with a destination tag, Stellar with a memo, and Toncoin, renamed Gram in June 2026, with a comment. On these ledgers a casino commonly keeps one shared address for every player, in part because each new account on XRP and Stellar must hold a locked balance, and tells deposits apart by the memo attached to each.

A deposit sent to that shared address without its memo still arrives, but it lands in the casino's wallet with nothing to say whose it is. Getting it credited then depends on support matching the transaction by hand, which some casinos do and others refuse. A wrong memo is worse, because it can credit another player.

The rule: When the cashier shows a memo, tag or comment beside the address, the deposit is not complete without it, and the wallet's own optional note field is where it belongs.

Two formats fold the memo into the address itself. An XRP address beginning with X carries the destination tag inside it, and a Stellar address beginning with M, called a muxed address, carries the account number the same way. When a casino issues one of those, no separate memo is needed. Where a network has no memo, each player is issued a dedicated deposit address instead.

Ethereum and the chains built to run its software, among them BNB Smart Chain, Polygon, Avalanche's C-Chain and the layer-two networks that settle onto Ethereum, derive an address from a private key in exactly the same way. The same key therefore controls the same 0x address on every one of them, and a wallet has no way to know which chain the recipient is watching. It will send USDT on BNB Smart Chain to an address the casino only watches on Ethereum without a single warning.

Coins sent this way are not destroyed. They sit at the same address on the chain they were sent on, and whether they can be recovered depends on the casino: it holds the key, so it can reach them technically, but it has to notice the deposit, agree to recover it, and it may charge for the work. Some casino terms say plainly that a deposit on an unsupported network is lost.

Across families the wallet usually protects you, because a TRON address starting with T will not pass for a 0x one. The traps that remain are format twins: a legacy Bitcoin Cash address has the same shape as a Bitcoin one, an Avalanche X-Chain address is not the C-Chain address a casino expects, and a private Litecoin send through its MWEB extension may not be credited at all. The cashier's network name, matched against the one selected in the wallet, is the check that catches all of them. What this means for ETH itself, layer-two networks included, is set out on the Ethereum casinos page.

No network charges by the amount sent. Each prices something else, and knowing what explains why a small deposit can cost as much as a large one.

• Bitcoin and its relatives (Litecoin, Dogecoin, Bitcoin Cash) charge for the bytes a transaction occupies in a block, at a rate that rises when many senders compete for the same blocks. The Bitcoin casinos page shows what that does to a small withdrawal.
• Ethereum-compatible chains charge gas: the computation a transfer needs, multiplied by a price per unit, with the base part of the fee burned. A token transfer needs more computation than sending the chain's own coin, and the fee is always paid in that coin, so a wallet holding USDT on Ethereum but no ETH cannot send it.
• TRON works with two resources instead of a fee auction. Bandwidth, which every account receives free each day, covers a plain TRX transfer; energy, needed for token transfers such as USDT, is obtained by staking TRX or paid for by burning it. The energy price was cut from 210 to 100 sun in August 2025.
• XRP and Stellar charge a fee too small to notice, but every account must hold a reserve that cannot be sent. On the XRP Ledger it is 1 XRP per account, with a further 0.2 XRP locked per trust line or other object, down from 10 XRP before December 2024; Stellar sets a minimum balance in the same spirit.
• Solana, Cardano and TON each add a rule of their own: Solana a small refundable deposit to open a token account, Cardano a minimum amount of ADA in every output, and TON a storage charge taken from an account's balance over time.

A confirmation is each block added to the chain after the one holding a transaction. On Bitcoin and the chains built like it, blocks are found by miners racing to solve a puzzle, and the moment of the next solution cannot be known in advance. Bitcoin aims for one block every 10 minutes, but that is only the average: one block in ten takes longer than 23 minutes, and one in a hundred longer than 46 minutes.

The key number: On a chain with random blocks the wait is a spread, not a time: one Bitcoin block in 7 takes more than twice its target of 10 minutes.

Asking for more confirmations lengthens the wait but evens it out. Dogecoin has a target block interval of 1 minute, and at the 40 confirmations commonly asked of it a deposit waits 40 minutes on average, with only one wait in ten passing 48 minutes: a long wait, but a predictable one.

Most of the newer chains on these pages settle differently. Validators vote on each block, and once enough of them agree the block is final: it cannot be reversed, and further blocks add nothing. The wait is then close to a fixed figure, from about a second on BNB Smart Chain to 13 minutes on Ethereum, where finality comes in epochs of 32 slots of 12 seconds each. TRON treats a block as settled once 19 more have been added on top of it.

The count a casino waits for is its own policy, not the network's, and the time it then takes to approve a payout comes on top. The withdrawals guide separates the two.

A probabilistic chain never declares a block final, so its row shows the confirmation count exchanges and casinos commonly ask for, as an average and as the wait one deposit in ten exceeds. On the other chains a block is settled once validators agree on it, and the time shown is close to constant. Tokens such as USDT, USDC, DAI, Shiba Inu and Chainlink take the time of the network they are sent on, and any casino may credit sooner or later by its own rule.
