Top 10 crypto wallet extensions for 2027

The browser wallets worth installing next year, compared on what decides whether your funds stay yours: where the private key lives, which chains and dApps work, Ledger support and fees.

Who wrote this list

Locker Protocol Wallet is our product, and it is first here. We put it first for one reason, stated openly: it is the only extension on this list that never stores a private key on the computer, by design rather than as an option. The nine others are compared on the same criteria, and each entry says what it does better than we do. Facts were checked against each wallet's official site, documentation and store listing in September 2026.

How the list was made

Where the private key lives

In the browser, even encrypted, a key is one malicious extension or one infected machine away from being drained. On a separate offline device, there is nothing to steal from the computer.

Chains and dApps

Which blockchains the extension holds, and whether the apps you already use find it when you press Connect.

Hardware and offline signing

Whether you can keep the key off the computer: a Ledger or another hardware wallet, or an air-gapped device that signs by QR code.

Fees

Installing a wallet is free. Built-in swaps and bridges usually are not: we note the fee the wallet itself adds when it publishes one.

Transparency and track record

Whether the code is public, and how the extension has held up: incidents are part of a wallet's history, and so is how they were handled.

Everyday use

How much the extension asks of you to send, swap or sign, and on which browsers it installs from an official store.

The ranking, one by one

1

Locker Protocol Wallet Our product

Best for keeping the key off the computer entirely

A browser extension that works with the dApps you already use, while the private key stays on a separate offline phone running the free Locker Vault app. Each transaction appears as a QR code: you check it on the phone, approve it there, and the phone shows the signature back as another QR code. Nine chain families come from one recovery phrase, and the connect buttons built for MetaMask, Keplr, TronLink or Freighter find it on their own.

Strengths

  • No private key in the browser: malware or a malicious extension on the computer has nothing to steal.
  • One extension for EVM chains, Solana, Bitcoin, Cosmos, Tron, Sui, Aptos, Stellar and the XRP Ledger, with swaps, bridges and Hyperliquid perpetuals built in.

Limits

  • Every signature takes a scan on the second device, slower than one click, and the wallet's source code is not published.

2

MetaMask

Best for the widest dApp support

The extension most dApps are built around, published by Consensys. Next to every EVM network it has held Solana natively since May 2025 and Bitcoin since December 2025, and it signs with more hardware wallets than any other extension here, from Ledger and Trezor to Keystone and GridPlus.

Strengths

  • EVM dApps support it first, and the Solana and Bitcoin accounts live in the same extension.
  • The longest hardware list: Ledger, Trezor, GridPlus Lattice, Keystone and other QR wallets.

Limits

  • The key sits in the browser unless you pair a hardware wallet, and built-in swaps carry a 0.875% MetaMask fee.

3

Phantom

Best for Solana

The reference wallet of the Solana ecosystem, with swaps, tokens and NFTs in one polished extension. It also holds Ethereum, Base, Polygon, HyperEVM and Bitcoin, and signs with a Ledger connected by cable. Its support for Sui ended on September 24, 2026.

Strengths

  • The smoothest Solana experience, and the wallet Solana dApps list first.
  • Ledger signing from the extension, for Nano S Plus, Stax and Flex.

Limits

  • No Trezor, no more Firefox updates, and no Arbitrum, Optimism or BNB Chain. Most swaps carry a 0.85% fee.

4

Rabby Wallet

Best for safer signing on EVM networks

Built by DeBank for Ethereum and EVM networks, Rabby shows how a transaction will change your balances before you sign it and flags risky approvals. Its code is public under the MIT license.

Strengths

  • Balance changes and risk warnings appear before each signature.
  • Open source under MIT, with hardware wallets such as Ledger and Trezor supported.

Limits

  • Focused on Ethereum and EVM networks, and its built-in swap carries a 0.25% fee.

5

Keplr

Best for Cosmos and IBC

The wallet of the Cosmos ecosystem: more than forty Cosmos SDK chains with IBC transfers and staking, plus Bitcoin and Starknet in the same extension. Its code is public under Apache 2.0, and its documentation still labels EVM support as beta.

Strengths

  • Staking and IBC transfers across Cosmos chains, built in.
  • Signs with a Ledger or a Keystone, and installs on Chrome, Firefox and Edge.

Limits

  • EVM support is still in beta, and the fee on its built-in swap is not published.

6

OKX Wallet

Best for the most networks in one extension

The self-custody wallet of the OKX exchange, announced for more than 140 networks, EVM, Bitcoin, Solana, Sui, Tron and Cosmos chains among them. Its built-in DEX publishes a fee schedule from 0% to 0.5% depending on the tokens.

Strengths

  • The widest list of networks here, from one recovery phrase.
  • A published swap fee schedule, from 0% to 0.5% depending on the pair.

Limits

  • Closed source, and its site does not document hardware wallet support.

7

Coinbase Wallet

Best for Coinbase users

Coinbase's self-custody extension for EVM networks and Solana, separate from the exchange account. The mobile app was renamed Base App in July 2025 and went back to Coinbase Wallet on September 10, 2026, while the extension kept its name throughout.

Strengths

  • A familiar brand for newcomers, and a short path from a Coinbase account.
  • Ledger signing from the extension.

Limits

  • No Firefox version, and a Chrome Web Store rating of 2.7 out of 5 in September 2026.

8

Backpack

Best for swaps and bridges without a wallet fee

A multichain wallet from the team behind Backpack Exchange, covering Solana, the main EVM networks, Sui, Aptos and more than a dozen others. Since March 2026 it charges no wallet fee on swaps and bridges, and it signs with Ledger, Trezor or Keystone.

Strengths

  • No wallet fee on swaps and bridges, on every network it supports.
  • Ledger, Trezor and Keystone are all supported.

Limits

  • A far smaller user base than the leaders, and a product closely tied to the Backpack exchange.

9

Zerion

Best for tracking a DeFi portfolio

A wallet built around portfolio tracking: positions, DeFi and history across Ethereum, Solana and more than fifty networks in one view. Its extension code is public under GPL-3.0 and was audited by Cure53, SlowMist, Zokyo and Secfault Security.

Strengths

  • The clearest view of DeFi positions across chains.
  • Open source, with four published security audits and a bug bounty.

Limits

  • A 0.67% fee on swaps and bridges, 0.25% with the paid Premium plan.
Official site Locker vs Zerion →
10

Xverse

Best for Bitcoin, Ordinals and Runes

The Bitcoin specialist: native bitcoin, Ordinals and Runes, Bitcoin layer 2s such as Stacks and Spark, and Starknet. It signs with a Ledger or a Keystone.

Strengths

  • Full support for Ordinals and Runes, which general-purpose wallets handle poorly or not at all.
  • Ledger and Keystone signing, with the key kept on the device.

Limits

  • Built around Bitcoin: for Ethereum or Solana you need a second wallet.

Questions people ask

What is the safest crypto wallet extension?

The one that keeps the private key off the computer. A browser extension that stores the key, even encrypted, can be emptied by malware, a malicious extension or a phishing signature. Pairing an extension with a hardware wallet, or using one whose key lives on an air-gapped device, removes that risk: the computer only ever sees public addresses and signed transactions.

Is MetaMask still the best wallet extension in 2027?

It is still the extension most EVM dApps are built around, and many others answer to the same interface. Whether it is the best depends on what you hold: MetaMask keeps its key in the browser unless you pair a hardware wallet, and other extensions cover chains, fees or a security model it does not.

Which wallet extensions work with a Ledger?

Most of the extensions in this list can sign with a Ledger device, as the table shows. A Ledger keeps the key on a USB or Bluetooth device you plug in. An air-gapped wallet goes one step further: the signing device never connects to the computer at all and exchanges data only through QR codes.

What is an air-gapped wallet?

A wallet whose private key sits on a device that never connects to any network: no Wi-Fi, no USB, no Bluetooth. Transactions travel to it and back as QR codes, so nothing on the internet can reach the key. Locker Vault turns a spare phone into one, for free.

Can one extension replace MetaMask, Phantom and Keplr?

Increasingly, yes. Multichain extensions now cover EVM chains, Solana and Cosmos from one recovery phrase. What matters is whether your dApps detect them: Locker Protocol Wallet answers the connect flows built for MetaMask, Keplr, TronLink and Freighter, and appears in the Wallet Standard list on Solana, Sui and Aptos.

Are crypto wallet extensions free?

Installing and holding is free with every wallet here. Built-in swaps and bridges usually carry a fee added by the wallet on top of network costs, and it varies from one wallet to another. Locker Protocol Wallet adds at most 0.25% to swaps and bridges and 0.05% to Hyperliquid orders, shown before you sign.

Try the extension that never holds your key

Install Locker Protocol Wallet on Chrome or Brave, set up the free Locker Vault on a spare phone, and keep using the dApps you already know.
