Bitcoin Long-Term vs Short-Term Holding Strategy: Which Is Better?
- 31 Oct 2025
Tether (USDT) is the world’s most widely used stablecoin, facilitating billions in daily volume across decentralized exchanges, payment platforms, and blockchain ecosystems. However, despite its stable 1:1 peg to the US dollar, using Tether in smart contracts introduces several technical risks that crypto users and developers must understand.
In this article, we break down the primary smart contract risks involved in Tether-based transactions, how these risks vary across chains, and the best practices for minimizing exposure.
Tether operates on multiple blockchains, including Ethereum (ERC-20), Tron (TRC-20), Solana, Avalanche, and BNB Smart Chain (BSC). On these platforms, USDT is governed by smart contracts that define token behavior—how it’s transferred, frozen, or integrated into DeFi protocols.

Tether itself is relatively stable from a codebase perspective. However, smart contracts on DeFi protocols that integrate Tether—such as DEXs, lending platforms, or liquidity pools—can be vulnerable. If these platforms are hacked or their code is exploited, users holding USDT within them could lose access to their assets.
To move Tether across chains (e.g., from Ethereum to BSC), users rely on cross-chain bridges—some of the most targeted tools in crypto. A breach in a bridge’s smart contract could result in loss or duplication of USDT. These events have caused millions in damage across the industry.
The Tether smart contract includes administrative privileges that allow freezing or blacklisting addresses. While this can help with compliance and fraud prevention, it also introduces centralization risk. If admin keys are compromised or misused, large amounts of Tether could be affected without user consent.

Anyone can create a smart contract and accept USDT as input. This opens the door for scam contracts that appear legitimate but are programmed to drain wallets or lock tokens. Always verify contract addresses and audit reports before interacting.
Use trusted DeFi protocols only. Check for audits and community reputation.
Avoid bridging USDT via unknown platforms. Stick to established bridges with strong security histories.
Check contract permissions. Understand what access a smart contract has before depositing USDT.
Use wallets with token approval management. Revoke access when it’s no longer needed.
Smart contracts are powerful tools, but they come with inherent risks—especially when integrated with widely used stablecoins like Tether. By understanding these risks and practicing security-first behavior, you can safely leverage Tether in DeFi and beyond.
