Quick answer
Pay for a gift card with USDT ERC-20: send the exact USDT amount on Ethereum within the 30-minute invoice; 12 confirmations (about 2.4 minutes); typical gas 0.0000073–0.0000088 ETH, about US$0.02 (checked 21 Oct 2026); code delivered within 24 hours of confirmation; no KYC up to US$1,000. On that date ERC-20 was the least expensive way to send USDT, ahead of TRC-20.

How much gas does a USDT ERC-20 payment use?
A USDT transfer used 54,128 gas on Etherscan's list, about US$0.018 at 0.135 gwei on 21 Oct 2026. Etherscan prices a generic ERC-20 transfer at 65,000 gas, or US$0.022. Ethereum.org gives the formula: gas used × (base fee + priority fee).
At 18:34 UTC the base fee was 0.135 gwei and the Standard tip was 0. Your wallet sets a gas limit above the gas used, but you pay only for gas used. Hold about 0.00002 ETH for gas; that covered one USDT transfer more than twice over.
Why is ERC-20 the cheaper USDT network right now?
Ethereum gas was very low at 0.135 gwei, while Tron energy kept its set price of 100 sun. A USDT TRC-20 transfer without staked energy burned 6.4285 TRX (US$2.14), about 100 times the ERC-20 gas bill.
Exchanges priced it the same way: OKX charged 0.46 USDT on ERC-20 against 1.5 on TRC-20, Binance 0.6 against 1.5, Kraken 0.7404 against 1. Gas can spike, so check the network fee table before a large order.
How do I avoid sending USDT on the wrong 0x network?
Pick "Ethereum (ERC20)" by name, because many networks share the 0x address format. Binance offers USDT on BNB Smart Chain (BEP20), Arbitrum One, Optimism, Polygon POS, Scroll and opBNB, all with 0x addresses. Kraken and OKX also list USDT0 on Optimism, Plasma, Unichain and X Layer.
USDT sent on BEP20 or Arbitrum lands on another chain and cannot match an Ethereum invoice.
What else trips up ERC-20 payments?
- No ETH for gas: a wallet holding only USDT cannot send it on Ethereum.
- Fee deducted: OKX takes 0.46 USDT, Binance 0.6 and Kraken 0.7404 from the amount typed. Add it on top.
- Minimums: OKX 2 USDT, Binance 3, Kraken 0.88848.
- USDC mix-up: USDT and USDC share 0x addresses, but a USDT invoice needs USDT. For USDC, open a USDC invoice.

USDT ERC-20 questions
Do I need ETH to send USDT ERC-20?
Yes, from your own wallet: Ethereum gas is paid in ETH, never in USDT. On 21 Oct 2026 a USDT transfer needed about 0.0000073 ETH (US$0.018). From an exchange you need no ETH; it deducts a flat USDT fee instead.
How many confirmations does Gifts With Crypto need for USDT ERC-20?
Twelve. Ethereum slots last 12 seconds, so 12 confirmations take about 2.4 minutes when no slot is missed. Delivery within 24 hours starts after the 12th block.
Can I pay with USDT on Arbitrum, Polygon or BNB Smart Chain?
No. Gifts With Crypto accepts USDT on Ethereum (ERC-20) and Tron (TRC-20) only. Arbitrum, Polygon and BEP20 share the 0x address format but are separate networks.
What gas price should I set for USDT ERC-20?
Use your wallet's standard setting. On 21 Oct 2026 Etherscan showed 0.135 gwei Standard and 0.145 gwei Rapid, both confirming in about 30 seconds. A high manual tip only raises the cost.
