Trust Wallet is a mobile, self-custody crypto wallet that works across many blockchains. It was founded in 2017 by the Ukrainian developer Viktor Radchenko and was bought by Binance in July 2018, the exchange's first acquisition. Since then it has stayed a free app aimed at people who want to hold their own crypto without going through a custodian.
It is a hot wallet, which means it runs on an internet-connected device, usually a phone. That makes it quick to set up and handy for everyday use, swaps, and connecting to apps, with the trade-off that the keys live on a device that is online. The custody model is non-custodial: your private keys and recovery phrase are generated and stored on your own device and are never sent to Trust Wallet's servers. You hold the keys, so you also hold the job of backing up the recovery phrase and keeping it private. Anyone who has that phrase can move the funds, and losing it with no backup means losing access.
Trust Wallet is built around breadth. It supports a wide range of blockchains natively, including Ethereum, BNB Chain, Bitcoin, Solana, Polygon, Avalanche, Tron, and Cosmos, and it can hold a very large number of tokens across them. Because the supported networks and asset counts keep growing, check the current list on the official site rather than trusting a fixed figure. Beyond storing and sending, the app handles NFTs, staking for proof-of-stake assets, token swaps through built-in exchange routing, and a browser for decentralized apps.
On the technical side, Trust Wallet is built on an open-source library called Wallet Core, released under the MIT license, and the company says it runs independent third-party security audits. Open code lets outside developers and researchers inspect how the wallet handles keys and transactions.
Trust Wallet is best understood as a broad, mobile-first hot wallet for active, everyday crypto use across many chains. As with any hot wallet, the protection comes down to the device it runs on and how carefully you guard the recovery phrase. People holding larger amounts often keep the bulk in cold storage and use a phone wallet like this one for the funds they actually move. The app is free to download; for the current feature set and supported networks, check the official Trust Wallet site.
