USDT ERC-20 QR Code Generator

Create a payment QR code for Tether (USDT) on Ethereum. With an amount, the code becomes an EIP-681 token transfer request that pre-fills the payer's wallet; without one, it is a reusable code for any amount.

What is a USDT ERC-20 QR code?

A USDT ERC-20 QR code encodes either your Ethereum address or an EIP-681 token transfer request against the Tether contract (0xdAC17F958D2ee523a2206206994597C13D831ec7) as a scannable image. With an amount, a compatible wallet opens a USDT send screen pre-filled with your address and the amount in the token's 6-decimal units; without one, the code is a reusable receiving address.

How to create a USDT ERC-20 QR code

Copy your Ethereum address (0x..., 42 characters). The same address receives ETH, USDT and every other ERC-20 token.
Select "USDT (ERC-20)" and paste it.
Enter the amount in USDT for an invoice, or leave it blank for a general receiving code.
Download the image or copy the link. The link opens directly in wallets that register the ethereum: scheme.

What is inside the code

With an amount, the QR code encodes an EIP-681 transfer request: ethereum:0xdAC17F958D2ee523a2206206994597C13D831ec7@1/transfer?address=0xYourAddress&uint256=25000000. The first address is the USDT contract, @1 selects Ethereum mainnet, address is you, and uint256 is the amount in the token's smallest unit. Wallets that understand EIP-681 open a USDT send screen with everything filled in.

USDT networks compared

Network	Address format	Decimals	Payment-link standard
Ethereum (ERC-20)	0x… 42 characters	6	EIP-681 transfer request
Tron (TRC-20)	T… 34 characters	6	none widely adopted; plain address
Solana (SPL)	32–44 Base58 characters	6	Solana Pay transfer request

Worked example: a 25 USDT invoice becomes uint256=25000000 in the ERC-20 link (25 × 10⁶), and 0.5 USDT becomes 500000. Amounts with more than 6 decimal places cannot be represented by the contract, so round to 6 before you invoice.

Gas reminder for payers

Sending USDT on Ethereum requires ETH for gas in the sender's wallet, typically a few dollars. If your customers are new to crypto, mention this, or offer a TRC-20 or Solana code as a cheaper alternative.

Safety checklist

Verify the address. Compare the first 6 and last 6 characters on the card with your wallet's receive screen before you print or share.
Test with a small amount from another wallet before relying on the code.
Never put a seed phrase or private key into any website, including this one. A QR code for receiving only needs the public address.
Replace the code if you rotate addresses. Old codes keep working, so retire printed copies you no longer want to receive to.

USDT ERC-20 QR FAQ

What contract address is used?

The official Tether USDT contract on Ethereum mainnet, 0xdAC17F958D2ee523a2206206994597C13D831ec7, with 6 decimals. You can verify it under "Show encoded content".

Why does the amount look multiplied in the code?

USDT has 6 decimals, so 25 USDT is stored as 25000000 in the uint256 field, exactly as the token contract expects.

Which wallets support EIP-681 token transfers?

MetaMask Mobile, Trust Wallet, Rainbow, imToken and several others. Wallets without support still recognise the address inside the link; if a customer has trouble, switch to the plain-address option.

What about USDC?

Choose USDC (ERC-20) in the coin selector. It uses the Circle contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, also 6 decimals.

Can I receive USDT on Polygon or Arbitrum with this code?

The address is the same on every EVM chain, but the EIP-681 link declares chain ID 1 and the Ethereum mainnet contract, so wallets will send on Ethereum. For another chain, use the plain-address option and tell the payer which network to select.

Is ERC-20 or TRC-20 better for receiving USDT?

ERC-20 is the most widely held version and integrates with Ethereum DeFi, but transfers cost more. TRC-20 is cheaper for small payments. Many merchants offer both; see the TRC-20 generator.
