WalletChan

Sign smarter. Move faster.

A self-custodial web3 browser wallet for serious Ethereum and EVM use.

Website · Chrome Web Store · Firefox · Releases

WalletChan brings Ledger and Trezor hardware wallet support, existing Safe multisigs, Privacy Pools ETH shielding, and supported-token network fees into one redesigned extension. Readable transaction review runs across the experience so you can understand what will happen before approving.

It also supports private-key, seed-phrase, view-only, and Bankr API accounts, along with swaps, bridges, batching, custom networks, and decentralized website browsing.

One wallet for every EVM chain

Use the right account for the job

• Connect Ledger accounts through Chromium WebHID or Trezor accounts through the official Trezor Connect popup, then approve transactions and messages on the device.
• Discover or import existing Safe multisigs, review their configuration, propose transactions, collect approvals, and execute at quorum.
• Add private-key, seed-phrase, view-only, and Bankr API accounts.
• Assign accounts and networks to connected dapps without repeatedly changing one global wallet context.

Understand what happens before approving

• Review plain-language transaction intent and signer identity.
• Preview simulated asset changes.
• Decode calldata and supported clear-signing descriptors.
• Inspect signature domains, messages, and technical details.
• Batch compatible approvals and actions into fewer confirmations.

Shield ETH inside the wallet

Shield Ethereum ETH into a Privacy Pools balance and unshield through supported private-relay, recipient-paid, or public-recovery paths.

Privacy Pools uses ASP/compliance processing and has minimums and fees. It currently supports Ethereum ETH Shield/Unshield, not private in-pool transfers. Public recovery can link the original deposit and exit.

Pay network fees with supported tokens

Eligible accounts and requests can pay network fees with supported ERC-20 tokens, including USDC on supported chains. Availability depends on the account, chain, token, request, and transaction. Ledger accounts use native gas.

Move across the EVM ecosystem

• Swap and bridge supported assets without leaving the wallet.
• Use built-in EVM networks or add custom RPC endpoints.
• Browse ENS, IPFS, and other supported decentralized names in an ordinary browser, with optional local IPFS support.
• Use WalletConnect and injected dapp connections.
• Keep WalletChan open as a popup, side panel, compact view, or full window.

Privacy and control

• Private keys and seed phrases are encrypted locally.
• Ledger and Trezor keys remain on the hardware device.
• WalletChan does not add behavioral analytics or advertising trackers to the extension.
• User-invoked features still connect to blockchain RPCs and required service providers.
• The extension and its build system are open source.
