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

Gemstone walleta fully open source self-managed wallet, today announced a comprehensive USDT infrastructure spanning over 10 blockchains, addressing the fragmented stablecoin experience that has plagued crypto users. With USDT now exceeding $140 billion in market cap, users face increasing 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 between chains remains costly, complex, and increasingly dangerous. Users must navigate:

• Multiple packaged versions of USDT in different chains
• High gas fees on Ethereum (ERC20) vs cheaper alternatives like Tron (TRC20)
• Increasing 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-management interface:

Safety approach

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

True multi-chain USDT support

• Native support for more than 10 blockchains, including Tron, Ethereum, Solana, BNB Chain and TON
• Smart asset search automatically locates USDT balances across all supported chains
• Uniform interface eliminates circuit complexity

Cost-optimized transfers and trading

• Integration with more than 10 decentralized swap providers (THORChain, Near Intents, Uniswap, Across Protocol)
• User-managed network cost settings
• Automatic routing to lowest cost swap options
• USDT Bridging with Transparent Rate Comparison

Worldwide Fiat access

• Seamless entry and exit via MoonPay, Paybis and Transak
• 120+ countries supported
• 30+ payment methods, including Apple Pay and Google Pay
• Instant USDT purchases without any intermediate steps

Why this matters now

“USDT has become the backbone of crypto liquidity, but users are being forced to become on-chain experts just to move their stablecoins,” said Max Costa, Chief Marketing Officer at Gem Wallet. “We see hundreds of millions lost due to poisoning attacks as users pay unnecessary fees swinging back and forth between bridges and exchanges. Gem Wallet brings enterprise-level USDT management to regular users while maintaining full self-control.”

Address poisoning protection alone addresses a threat that will cost users more than $100 million by 2024, with attackers sending small amounts of money from similar addresses to poison transaction history.
