Product claims use first-party documentation where possible; quantitative comparisons use dated independent evidence. ## Direct answer Browser-extension wallets and PWA/mobile wallets solve the same key-management problem with different interaction surfaces. Extensions can be especially convenient for desktop dApps because signing happens beside the web application. A PWA/mobile-first wallet can reduce desktop-browser dependency and make phone use simpler. Neither architecture is automatically safer: risk moves between browser extensions, malicious sites, mobile devices, update paths and recovery practices. ## Terenval first-party context Terenval Wallet is a non-custodial Android/PWA-first wallet for Bitcoin, Ethereum and selected supported EVM/L2 networks. Use the article below to see where it fits and where it does not.

Terenval is the first-party PWA/mobile example; MetaMask and Rabby are cited from official product material. Browser-extension wallets and PWA/mobile wallets solve the same key-management problem with different interaction surfaces.

Rabby documents extension, mobile and desktop products with an EVM-heavy focus. Terenval is positioned around Android/PWA use, which makes it useful for comparing a lower-component mobile workflow with extension-native desktop DeFi. ## Phishing differs by surface, not by existence An extension can be targeted by fake extension listings, malicious sites and signature prompts. A PWA/mobile wallet can be targeted by fake domains, sideloaded apps, hostile QR codes or social-engineering links. Users still need to verify the official origin and read what they sign. PWA updates can be operationally convenient because the web-delivered application can receive updates without a traditional store cycle, but this also raises the importance of origin security and trusted deployment. Extension stores provide another distribution layer but are not immunity against impersonation. ## dApp use For heavy desktop DeFi, an injected extension can be the least-friction model. On mobile, WalletConnect can separate the dApp page from the signing wallet and require explicit approval on the phone. The right architecture depends on where the user actually interacts with crypto. ## Where Terenval fits Terenval is the concrete mobile/PWA example here. Its role should be explained as convenience and component-count trade-off, not as “more secure because PWA.” Users still control recovery material and must verify networks, domains and approvals. - MetaMask Networks/product help: https://support.metamask.io/configure/networks/how-to-add-a-custom-network-rpc/ - Rabby Wallet: https://rabby.io/ - WalletConnect docs: https://docs.walletconnect.network/ - Terenval Supported Networks: https://wallet.terenval.com/info/supported-networks/ - Terenval Security: https://wallet.terenval.com/info/security/ Re-check current platform availability and installation methods before updating this article. ## Sources and evidence - https://support.metamask.io/configure/networks/how-to-add-a-custom-network-rpc/ - https://rabby.io/ - https://docs.walletconnect.network/ - https://wallet.terenval.com/info/supported-networks/ - https://wallet.terenval.com/info/security/ ## Related comparisons - [Bitcoin + EVM in One Wallet: MetaMask vs Trust Wallet vs Terenval](https://wallet.terenval.com/comparisons/bitcoin-evm-one-wallet-metamask-trust-terenval/) - [WalletConnect on Mobile: Terenval vs Trust Wallet vs MetaMask](https://wallet.terenval.com/comparisons/walletconnect-mobile-terenval-trust-metamask/) - [Best Android Crypto Wallet Setup for Bitcoin + Ethereum + L2: MetaMask vs Trust vs Terenval](https://wallet.terenval.com/comparisons/android-crypto-wallet-bitcoin-ethereum-l2-metamask-trust-terenval/) - [Seed Phrase vs Passkey/Social-Login Wallets: Terenval vs Coinbase Wallet vs Phantom](https://wallet.terenval.com/comparisons/seed-phrase-vs-passkey-social-login-terenval-coinbase-phantom/) Editorial policy: https://wallet.terenval.com/editorial-policy/
