SWITZERLAND (MarketsXplora) Tangem, the Swiss-based hardware wallet maker, will release a significant update to its mobile app on Monday, introducing a redesigned WalletConnect interface, new security layers, and support for tokens on the Stellar and XRP ledgers. The upgrade is being billed by the company as its most feature-packed release in recent months, with more improvements than the last four updates combined.
The changes are aimed at making decentralized finance (DeFi) and Web3 platforms easier and safer to access, while extending the range of digital assets users can manage directly from their Tangem cards or rings.
Tangem Combats Crypto Fraud with “Transaction Simulation”
Version 5.27 represents what the company calls a “black hole defense system” against fraudulent dApps, combining real-time transaction simulation with artificial intelligence-powered threat detection through a partnership with blockchain security firm Blockaid.
The timing couldn’t be more critical, as reports of fake wallet synchronization schemes and malicious smart contracts continue flooding Tangem’s support channels.
“We’re putting behind us the days of connecting to a dApp and signing transactions without knowing what will happen next,” the company stated in its release announcement, positioning the update as the crypto industry’s answer to blind signing vulnerabilities that have enabled countless rug pulls and exit scams.
The centerpiece of the update transforms how users interact with decentralized applications across Solana, Ethereum, and other EVM-compatible networks. Instead of the traditional approach where users approve transactions based on limited information, Tangem’s new WalletConnect interface now “dry-runs” every transaction off-chain before any signature occurs.
This transaction simulation technology computes exact balance changes, uncovers potential smart-contract errors, and flags hidden operations, delivering what Tangem describes as a “human-readable preview” of on-chain effects. The system bundles the original transaction, simulation output, and validation report into a cryptographically signed payload called VTX (transaction verification), ensuring no tampering occurs between preview and execution.
Tangem Wallet Update 2025 Adds Blockaid Scam Detection
The update’s most aggressive anti-fraud measure comes through its Know Your dApps (KYDA) feature, which automatically vets every dApp before connection attempts. When users scan QR codes or tap deep links, Tangem immediately sends the target dApp’s URL and smart-contract addresses to Blockaid’s threat intelligence database.
Blockaid’s analysis extends beyond simple blacklists, conducting real-time behavioral analysis on smart-contract code through pattern recognition algorithms. The system scans bytecode for known scam constructs including rug-pull hooks, multi-signature bypasses, and hidden fee mechanisms, while parsing exposed methods to identify suspicious functions like unauthorized token minting or concealed admin privileges.
High-risk contracts trigger double-confirmation flows requiring users to acknowledge dangers before proceeding. Even newly spawned or low-reputation dApps prompt security alerts, though users retain override capabilities after risk acknowledgment.
“Although KYDA doesn’t eliminate all scam risks, it significantly reduces them by analyzing dApps and warning users not to connect to these scam domains,” Tangem explained, noting that all security checks complete in under one second to maintain seamless user experience.
The enhanced WalletConnect interface now supports connections to multiple networks during single sessions, spanning popular platforms including OpenSea, Uniswap, 1inch, Raydium, and PancakeSwap across Ethereum, BNB Smart Chain, Polygon, Avalanche, zkSync, Base, Arbitrum, and Optimism networks.
Version 5.27 Release Expands Token Coverage
Beyond security enhancements, version 5.27 significantly expands Tangem’s token support through integration with Stellar and XRP Ledger networks, both designed as high-speed, low-cost payment rails for cross-border transactions.
The Stellar network integration enables direct storage, sending, and receiving of XLM tokens plus various stablecoins including USDC and EURC, alongside project tokens such as SHX, RIO, WXT, MOBI, NWC, and TFT. Similarly, XRP Ledger support allows management of XRPL tokens including RLUSD, positioning Tangem to capitalize on institutional adoption of these enterprise-focused blockchain networks.
The update requires only app installation without wallet reconnection or dApp reauthorization, maintaining existing user sessions while immediately activating new security protocols. Tangem emphasizes that while their security measures significantly reduce risk exposure, no system guarantees complete protection, urging continued user vigilance.
The company recommends users verify dApp domains before connecting, avoid official URL lookalikes particularly those ending in “.io,” never ignore warning prompts, maintain updated app versions, disconnect after dApp usage, read transaction details carefully, and periodically revoke unused token permissions through services like revoke.cash.
