What is ERC20?
ERC20 is the token standard of the Ethereum blockchain — the rulebook a token's smart contract follows so wallets, exchanges and desks can recognise and move it. USDT exists on Ethereum as an ERC20 token, which makes ERC20 the second network, after Tron, that UAE sellers use to deliver USDT to a desk.

How ERC20 works
ERC20 is a fixed set of functions, dating from 2015, that a smart contract on Ethereum implements: transfers, balance checks and spending approvals. Ethereum produces a block roughly every 12 seconds, so a transfer normally confirms within about a minute, with finality around 13 minutes. Every transfer pays gas in ETH, and the gas price floats with congestion: a USDT send cost under a cent at September 2026 gas prices and ran past US$50 at the May 2021 peak. That floating fee is the practical difference from Tron's flat model, covered in the TRC20 entry.
Ethereum addresses start with "0x", Tron addresses with "T". The official USDT contract on Ethereum is 0xdAC17F958D2ee523a2206206994597C13D831ec7, verifiable on Etherscan; a USDT balance under any other contract is a different token. Tether's data shows Tron carrying about half of all USDT and Ethereum most of the rest, as of September 2026.
Why it matters when selling USDT in the UAE
ERC20 changes only the transfer leg of a sale; the quote, spread and bank settlement are identical whether you send ERC20 or TRC20. Choose ERC20 when the USDT already sits on Ethereum or the counterparty only supports Ethereum addresses; otherwise TRC20's flat fee is cheaper. On settlement-size tickets the fee rarely decides it: even US$25 of gas is 0.01% of a 250,000 USDT sale.
Illustrative example
Selling 250,000 USDT on ERC20 at the 0.08% band costs 200 USDT (about AED 735) in desk spread, fixed in the written quote, plus roughly US$2 to 20 of gas to the network, under 0.01% of the ticket. The full bands, 0.08% to 0.40% by size, are in the pricing section, as of September 2026.
FAQ
Is ERC20 the same as Ethereum?
No. Ethereum is the blockchain; ERC20 is the standard that tokens follow on it. ETH is Ethereum's native coin and pays the gas; USDT on Ethereum is an ERC20 token issued by Tether.
How much does an ERC20 USDT transfer cost?
The fee is gas paid in ETH, and it floats with congestion — from under US$1 in quiet periods to tens of dollars at peak, as of September 2026. The fee goes to the network, not to any desk or wallet.
How long does an ERC20 transfer take?
Ethereum produces a block roughly every 12 seconds, so an ERC20 transfer normally confirms within about a minute. Full finality — the point where reversal is practically impossible — takes around 13 minutes.
Can I send ERC20 USDT to a TRC20 address?
No — the networks are incompatible and the tokens will not appear where you expected. Recovery is sometimes possible only if the recipient controls the same key on Ethereum. Confirm the network in writing and test a small amount first.
