TRC-20, ERC-20 and BEP-20: the three networks compared

USDT is not one token. It is a separate contract on every chain it lives on, and Tether’s integration guidelines ask platforms to treat them as equal in value (“1 TETHER token on Blockchain X = 1 TETHER token on Blockchain Y”) and to make “explicitly clear” which protocols they support. A casino does that with the network selector in its cashier. The last column counts the reviewed casinos whose documents name each network for USDT; twenty name the coin, and fifteen of those say on which networks.

Address formats as casinos and wallets show them: Stake’s USDT withdrawal guide gives the 0x prefix for ERC-20, BEP-20 and Polygon and T for TRC-20. Fee mechanisms from each chain’s own documentation, and Tether status from its Supported Protocols page (13 Nov 2026), all listed under Sources.

Which reviewed casinos list which USDT network

The matrix covers the fifteen reviewed casinos that publish their USDT networks. Five more name USDT without a network: 500 Casino, BetFury, FortuneJack, Jack.com and RealBet. For those, and for any casino on a day its list may have changed, the deposit page is the only authority.

Sources per casino are in the table on our USDT casinos page. No reviewed casino lists USDT on Arbitrum, Base or Optimism. Arbitrum appears for USDC at Roobet, Shuffle, Rainbet and Thrill, and Stake names Arbitrum, Optimism, Base and Cronos among the networks it does not support.

TRC-20 (TRON): cheap only with staked Energy

TRON meters two resources. Bandwidth pays for the bytes of a transaction, and each activated account has 600 free units, which is why a plain TRX send usually costs nothing. Energy pays for smart-contract execution, and a USDT transfer is a contract call. TRON’s developer documentation (updated 20 October 2026) is direct about the difference: “Energy has no free quota — accounts must either stake (or receive delegated) TRX to obtain it, or rely on the TRX-burn fallback.” The burn rate is a chain parameter, 100 sun (0.0001 TRX) per unit of Energy, and it was the same on both sample dates.

In the 29 October sample a USDT transfer consumed 64,285 Energy when the recipient already held USDT and 130,285 when it did not. Burned at 100 sun, that is 6.43 or 13.03 TRX: $2.13 or $4.31 at that day’s TRX price, $2.03 or $4.11 at the 13 November price. Most senders in the sample paid far less, because exchanges and wallet services stake TRX and cover Energy for their users: 311 of the 589 transfers paid no TRX at all, and only 51 paid 6 TRX or more.

TRC-20 is therefore cheap for a casino and for an exchange and can be the dearest route for a self-custody wallet. Casino fee tables reflect that unevenly. Cloudbet’s Tron row was its most expensive USDT withdrawal on both dates (3.84 USDT on 29 October, 2.95 USDT on 11 November, with a 5 USDT minimum), while Stake, Thrill and Wild.io charge the same 1 USDT they charge on any chain. Roobet adds a warning for wallets in which a relayer pays the Energy: gasless wallets “are not supported on our platform at this time”, and depositing from one “may result in loss of funds” (article dated 14 July 2025). TRON schedules a block slot every 3 seconds; Thrill’s help centre gives 1 to 2 minutes as the usual arrival time on the network.

ERC-20 (Ethereum): the widest acceptance

Ethereum prices a transaction in gas. ethereum.org gives the cost as units of gas used multiplied by the base fee plus a priority fee. The base fee is set by the protocol from how full recent blocks were, “will increase or decrease by a maximum of 12.5% per block”, and is burned; the priority fee is a tip to the validator. A plain ETH transfer uses 21,000 gas. The 25 USDT transfers sampled on 29 October used 41,300 to 63,200, the higher figure when the recipient had never held USDT. The sender needs ETH in the wallet for this: USDT cannot pay its own gas.

At each sample’s median base fee (0.257 gwei on 29 October, 0.068 gwei on 13 November) those transfers cost about four to six cents, then about one cent. The older rule of thumb of several dollars per ERC-20 transfer described neither date. It can describe a busy hour, because the 12.5% steps compound: twenty consecutive full blocks, four minutes of chain time, multiply the base fee about tenfold (1.125 to the power of 20 is 10.5).

ERC-20 is the network most reviewed casinos accept for USDT: 14 of the 15 that publish a list. mBit lists USDT as “ERC-20 only”, and Rollbit’s deposit guide takes “An array of ERC-20 Tokens including USDT + USDC”. Cloudbet’s Ethereum row carried a 0.0319 USDT fee and a 0.1 USDT minimum on 11 November, the lowest USDT minimum on its page. Ethereum’s slots are 12 seconds long and a block is finalised after two 32-slot epochs, about 12.8 minutes, but casinos credit well before finality: Roobet after 3 confirmations, BC.Game after 6. Wild.io’s own table puts an ERC-20 USDT withdrawal at 15 to 20 minutes in total, against about 10 on its other three networks.

BEP-20 (BNB Smart Chain): low gas, and not on Tether’s list

BNB Smart Chain uses Ethereum’s address format and gas model, with BNB as the gas coin. BNB Chain’s documentation describes “the network-wide adoption of a 0.05 Gwei standard gas price”, typical fees “around $0.005 or less” and a block time of “approximately 0.45 seconds”. A public node returned 0.05 gwei on both sample dates, which puts a token transfer well under one cent.

Two cautions come with it. First, Tether’s Supported Protocols page names BNB Smart Chain only with a Tether Gold (XAU₮) address, and Tether’s transparency data shows no USDT in circulation there. The token a cashier credits as BEP-20 USDT is therefore not one Tether says it issues or redeems; a casino can still accept it, since each casino decides which contracts it watches. Second, the address is a 0x address. A BEP-20 transfer to a deposit address the casino watches only on Ethereum looks valid in the wallet and arrives where the cashier is not looking. Eleven reviewed casinos list BEP-20 for USDT; BitStarz, BC.Game, mBit and Rollbit do not.

On this chain the casino’s fee, where there is one, is nearly the whole cost. Cloudbet listed 0.00326 USDT on 11 November; Stake and Thrill charge 1 USDT, several hundred times the gas.

Solana, Polygon, TON and Avalanche

Solana is listed for USDT by ten reviewed casinos. The Agave validator documentation bases the fee on “the number of signatures in the transaction”, plus an optional prioritisation fee equal to compute units times a price the sender chooses; every one of 1,709 single-signature transactions sampled on 29 October paid 5,000 lamports, a small fraction of a cent. The cost that surprises people is the token account. In the SPL Token documentation’s words, “If the receiver does not yet have an associated token account, the sender may choose to fund the receiver’s account”, and the network’s rent query priced that deposit at 1,488,440 lamports (0.00148844 SOL) on both dates, about $0.15 and then $0.12. Thrill halves its USDT fee to 0.5 on Solana. Cloudbet’s Solana row cost 0.436 USDT with a 20 USDT minimum, the highest USDT minimum on its page. Gamdom takes USDC and USD1 on Solana but not USDT, and BitStarz lists SOL itself while keeping USDT to TRC-20 and ERC-20.

Polygon is listed by six: Stake, Shuffle, Cloudbet, BetPanda, Duel and Thrill. Gas is paid in POL, which Polygon’s documentation calls “the gas and staking token on Polygon Chain”, and a transfer cost about a fifth of a cent on both sample dates. Polygon does not appear on Tether’s Supported Protocols page, so the same caveat applies as on BNB Smart Chain. Cloudbet’s fee was 0.00171 USDT; Thrill’s is 1 USDT.

TON and Avalanche C-Chain are both on Tether’s list, and among reviewed casinos only Cloudbet names them for USDT, at 0.00141 and 0.00297 USDT with a 1 USDT minimum (11 November). Shuffle’s help centre, which lists Toncoin under the name GRAM, treats a missing memo on such a deposit as a mistake that support has to investigate, so check whether a TON deposit page shows a memo field.

Does the casino or the blockchain charge the fee?

Both, at different moments. On a deposit the chain charges the sender, which is you or your exchange; among reviewed casinos Cloudbet prints a deposit fee of 0 on every row of its fee page and Rollbit states “We charge no fees on deposits.” On a withdrawal the casino is the sender, pays the chain, and passes on a figure of its own choosing. The table shows how far apart those figures are for one coin.

Fees in USDT per withdrawal, as each operator publishes them. On a 50 USDT withdrawal that is 5.9% at Cloudbet on Tron and 0.06% on Ethereum, 2% at Stake, Thrill and Wild.io, and 1% at Thrill on Solana (arithmetic from the table). RealBet, which does not state its USDT network, charges 1% of the amount up to a cap of 20.02 USDT, with a 5 USDT minimum.

A casino that says it charges nothing of its own still deducts the network fee, and the amount is shown before you confirm. A flat fee, by contrast, is a price: at 1 USDT it was a few hundred times the gas on BNB Smart Chain or Polygon on both sample dates. The cheapest network for the sender on the way in is often not the cheapest on the way out, so read the withdrawal row before choosing where to deposit. Costs across other coins are in our cheapest crypto to deposit guide.

Choosing a network: four checks

1. Is it in the cashier today? A help article can lag the deposit page. Cloudbet’s fee page and its supported-coins article disagree on one USDC network, for example.
2. What does sending cost you? From an exchange, compare the exchange’s own withdrawal fee per network. From your own wallet, check live gas, and on TRON check whether you hold staked Energy.
3. What does the casino charge on the way back? Read the fee and the minimum for that network: 20 USDT on Solana at Cloudbet, 10 USDT at mBit, $20 at Winna.
4. Can your wallet receive it? A withdrawal goes out on the network you select, and a wallet that does not watch that chain will not show it.

The network never changes how the games behave. Results of provably fair games can be recomputed with our free Provably Fair Verifier whatever coin funded the account, and the casino’s verification rules apply to USDT on every chain.
