Short answer

"Better" depends on the use case. Both keep private keys on-device, both are open source (Trust Wallet partially), both support EVM chains. MetaMask is the desktop dApp standard — almost every Ethereum dApp tests against MetaMask first. Trust Wallet is the mobile multi-chain default — easier for managing Bitcoin, Solana, Cosmos, TRON, and EVM chains all in one place. For US holders in 2026, the better question is whether to use Rabby instead of either.

Seven dimensions of comparison

Desktop dApp compatibility. MetaMask wins. Virtually every Web3 site has tested against MetaMask; some dApps still detect and refuse other wallets.

Mobile UX. Trust Wallet wins. Native mobile design, better swap aggregation, easier multi-chain switching.

Multi-chain breadth. Trust Wallet wins. Supports 100+ chains natively including Bitcoin, Solana, Cosmos. MetaMask focuses on EVM (Ethereum, Polygon, Arbitrum, Optimism, Base, BNB Chain).

Open source. MetaMask is fully open source. Trust Wallet is partially — core wallet code open, UI and some integrations closed.

Phishing protection. Both have basic transaction warnings, but neither pre-simulates transactions like Rabby does. Both routinely fail to flag malicious approval transactions.

Hardware-wallet integration. MetaMask supports Ledger, Trezor, Lattice. Trust Wallet recently added Ledger support but the integration is rougher.

Owner ownership. MetaMask is owned by ConsenSys (Joseph Lubin, an Ethereum co-founder). Trust Wallet is owned by Binance.

The Rabby alternative

For a US holder building a hot-wallet routine in 2026, Rabby (acquired by DeBank in 2022) has surfaced as the safer default. Pre-simulates transactions, flags suspicious approvals, supports more EVM chains natively, cleaner hardware-wallet integration. Same private-key-on-device model as MetaMask.

The recommendation

Desktop, ETH-only, frequent dApp interaction: MetaMask or Rabby (Rabby preferred for safety). Mobile, multi-chain casual: Trust Wallet. Anything serious: hardware wallet, software wallet only as the "trading float."
