Gem Wallet Adds Cross-Chain USDT Support with Integrated Swaps, Bridges, and Scam Protection

[PRESS RELEASE – San Francisco, United States, December 21st, 2025]

Self-Custody Wallet Eliminates Cross-Chain USDT Friction with Integrated Swaps, Bridges, and Anti-Scam Protection

Gem Wallet, a fully open-source self-custody wallet, today announced a comprehensive USDT infrastructure spanning 10+ blockchains, addressing the fragmented stablecoin experience that has plagued crypto users. With USDT now exceeding $140B in market capitalization, users face mounting challenges moving value across Tron (TRC20), Ethereum (ERC20), Solana, BNB Chain, TON, and other networks.

The Challenge: Cross-Chain USDT Functionality Remains Fragmented

Despite USDT’s ubiquity, sending stablecoins across chains remains costly, complex, and increasingly dangerous. Users must navigate:

• Multiple wrapped versions of USDT across different chains
• High gas fees on Ethereum (ERC20) vs. cheaper alternatives like Tron (TRC20)
• Growing address poisoning attacks targeting USDT holders
• Fragmented bridge and swap solutions
• Complex fiat on/off-ramps with limited geographic coverage

The Solution: Unified USDT Infrastructure

Gem Wallet consolidates the entire USDT lifecycle into a single self-custody interface:

Security-First Approach

• Address poisoning protection automatically flags suspicious transactions
• Fully open-source codebase for complete transparency (https://github.com/gemwalletcom/)
• Biometric authentication on mobile devices
• User-controlled private keys (true self-custody)

True Multi-Chain USDT Support

• Native support across 10+ blockchains including Tron, Ethereum, Solana, BNB Chain, and TON
• Smart asset search automatically locates USDT balances across all supported chains
• Unified interface eliminates chain-switching complexity

Cost-Optimized Transfers & Trading

• Integration with 10+ decentralized swap providers (THORChain, Near Intents, Uniswap, Across Protocol)
• User-controlled network fee settings
• Automatic routing to lowest-cost swap options
• USDT bridging with transparent fee comparison

Global Fiat Access

• Seamless on/off-ramp through MoonPay, Paybis, and Transak
• 120+ countries supported
• 30+ payment methods including Apple Pay and Google Pay
• Direct USDT purchases without intermediate steps

Why This Matters Now

The address poisoning protection alone addresses a threat that has cost users over $100M in 2024, with attackers sending small amounts from similar-looking addresses to poison transaction histories.
