Verified USDT and USDC contracts on every blockchain: official developer reference

This document is the canonical reference for any developer, merchant, or auditor who needs to verify the real smart contract address of USDT or USDC on the blockchains that TronDealer supports. We consolidate in one place the contracts officially issued by Tether and Circle, with a direct link to each network's block explorer and a note on decimals, so you never fall for a clone token or a scam.

Attackers publish tokens with the same ticker (USDT, USDC) but a different address, hoping someone will send real funds or accept payments in a token with no backing. The only way to prevent that is to confirm the contract address before signing a transaction, wiring up a webhook, or showing a QR code to a customer.

Why verify before integrating#

A crypto payment gateway is only as secure as its token allowlist. If you accept transfers to an address without validating it matches the official contract, you're opening the door to:

• Fake tokens with the same symbol. Anyone can deploy an ERC-20 called "USDT". Only the contract issued by Tether is backed 1:1.
• Bridged tokens mistaken for native ones. On Polygon, Arbitrum, and Optimism, two USDCs coexist: the bridged version (USDC.e, issued by the official bridge) and Native USDC (issued directly by Circle). TronDealer works with Native USDC on these networks.
• Addresses cloned with homoglyphs. Copying an address from a screenshot or Telegram chat is a classic vector. Always verify against an official source.

The canonical list below is exactly what our gateway uses internally to scan deposits. Use it as the allowlist in your own system.

USDT — Tether USD#

Official issuer: Tether Holdings Limited. On-chain symbol: USDT. 1:1 backing with reserves reported quarterly.

EVM networks#

TRON (TRC20)#

USDT on TRON (TRC20) moves the highest daily volume of any Tether deployment. It's the go-to for Hispanic and LatAm markets thanks to its very low fees, which is why TronDealer integrates energy renting to make transfers even cheaper.

Solana (SPL)#

TON (Jetton)#

On TON, USDT is implemented as a Jetton: there's a master contract (the issuer) and each holder has their own jetton wallet derived from it. TronDealer resolves the jetton wallet from the owner address using @ton/ton.

USDC — USD Coin#

Official issuer: Circle Internet Financial. On-chain symbol: USDC. Fully backed and audited monthly.

EVM networks — Circle Native USDC#

TRON (TRC20)#

Solana (SPL)#

Stellar#

On Stellar, an asset is identified by the (code, issuer) pair. Any Stellar address can issue an asset with code "USDC" — that's why the issuer is the real identifier. Only the one issued by GA5ZSEJY... is backed by Circle.

Other stablecoins supported by TronDealer#

Beyond USDT and USDC, TronDealer supports regional and EUR-denominated stablecoins on specific networks.

EURC — Euro Coin (Circle)#

DoC — Dollar on Chain (Money on Chain, Rootstock)#

DoC (Dollar on Chain) is a 1:1 USD-collateralized stablecoin backed by rBTC, the native currency of Rootstock (the EVM network secured by Bitcoin miners).

How to verify a contract programmatically#

The canonical way to check that an address is a live ERC-20 is to call its view methods (symbol, decimals, totalSupply) and compare them to the expected values.

If symbol returns anything other than USDT or USDC, or the call fails because there's no ABI at that address, that's a clear signal the address is not the official contract.

Recommended allowlist for integrators#

If you're building your own deposit scanner or wallet, we recommend hardcoding the allowlist instead of relying on dynamic config. It's one less attack surface:

export const STABLECOINS = {
  bsc: {
    USDT: { address: '0x55d398326f99059fF775485246999027B3197955', decimals: 18 },
    USDC: { address: '0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d', decimals: 18 },
  },
  eth: {
    USDT: { address: '0xdAC17F958D2ee523a2206206994597C13D831ec7', decimals: 6 },
    USDC: { address: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48', decimals: 6 },
  },
  pol: {
    USDT: { address: '0xc2132D05D31c914a87C6611C10748AEb04B58e8F', decimals: 6 },
    USDC: { address: '0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359', decimals: 6 },
  },
  arb: {
    USDT: { address: '0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9', decimals: 6 },
    USDC: { address: '0xaf88d065e77c8cC2239327C5EDb3A432268e5831', decimals: 

This structure is exactly what TronDealer uses internally (CHAINS in app/utils/v2-config.js) to filter Transfer logs in its deposit scanner.

Frequently asked questions#

Next step#

If your goal is to accept payments in any of these stablecoins without writing your own on-chain scanner, configuring RPCs, or managing gas, the fastest path is to use the TronDealer API directly. The full flow — registration, wallet assignment, HMAC webhooks, and automatic sweep — is covered in the 6-step integration guide.

If you just need to validate contracts in your dApp or wallet, this page is your source of truth. Bookmark it, keep the allowlist up to date, and never accept an address that isn't listed here without cross-checking against Tether Transparency or Circle.
