Sender Review 2026: Multi-Chain Web3 Wallet With SlowMist Audit

Sender is a Web3 wallet from Sender Tech Limited. It is available as a Chrome extension, an iOS app and an Android app, with the Android version also offered as an APK download.

The homepage positions it as an all-in-one tool: manage assets across 20+ blockchains, exchange them in the app, connect to decentralised apps and show off NFT collections. App store descriptions focus on Ethereum and NEAR compatibility, and the supported-network list also includes BNB Smart Chain, Avalanche, Polygon, Optimism, Arbitrum One, TON and zkSync Era.

Security is the main selling point. The project cites a SlowMist audit, a bug bounty of up to 50,000 USDT, a malicious-address blacklist and Ledger support. It mentions world-class investors but does not name them. Public reporting also show a Sender Network with an ASI token that describes itself as an AI protocol and says it began as a wallet.

Sender is a self-custody wallet. When you create an account, the app generates a recovery phrase, which controls your private keys. Those keys sign transactions on your device, so the project does not hold your funds.

The wallet talks to many blockchains. You pick a network, see your balances and NFTs, and send or receive tokens. For dapps, it connects the same way as a browser wallet: a site asks to connect, and you approve or reject each signature.

The homepage also lists an exchange feature for buying and selling assets in the app, and a Ledger integration. With a hardware wallet, the private keys stay on the Ledger device and the wallet only builds the transactions for you to approve.

Sender does not publish a fee schedule on its homepage. It promotes instant buying and selling in the app, but the rates and any spreads or service fees are not stated.

As with any wallet, you pay the network gas fee for each on-chain transaction, and that depends on the chain. Check the quote shown in the wallet before you confirm any swap or purchase.

Sender states that you control your private keys, so custody risk sits with you: lose the recovery phrase and the funds are gone, and if it leaks they can be stolen. The homepage cites an audit by SlowMist and a bug bounty of up to 50,000 USDT. It does not say when the audit took place or what it covered, so read the linked report. The project does not publish incident history on its homepage.

Hot wallets are exposed to phishing, malicious dapps and fake downloads. Install only from official store listings, check every signature request, and keep larger holdings on a Ledger or other hardware device. No licence or regulatory registration is stated, which is typical for non-custodial wallets, but exchange and purchase features may involve third-party providers with their own rules.

Sender fits crypto users who want one wallet for several chains, especially NEAR, Aurora and EVM networks, and who are comfortable managing their own recovery phrase. It also suits people who plan to pair the wallet with a Ledger device. Anyone who wants published fee tables or named backers will need to look elsewhere.
