Start auto-signing.

A minimal Chrome wallet for EVM chains with a feature MetaMask refuses to ship: per-rule whitelist auto-signing. Trust a dApp, a contract, or a single function selector — Auto Wallet signs the rest while you stay in flow.

Whitelist auto-signing

Three knobs. AND logic. One signature‑less life.

Auto Wallet's rule engine combines three independently-toggleable dimensions: domain, contract address, and 4-byte method selector. Toggle any subset — the rest fall back to a gas cap and value cap safety net.

Active rule
Uniswap routine
app.uniswap.org
Domain app.uniswap.org
Match any transaction originating from this exact origin. Strict — no prefix attacks.
Contract 0x68b3…2D45 · UniversalRouter
Restrict to a single contract `to:` address. Useful for locking auto-sign to one router.
Method 0x3593564c · execute()
4-byte function selector. Off = any method on the contract matches.

Everything the daily driver needs. Nothing it doesn't.

Multi-account, one password
Create or import unlimited accounts via private key or mnemonic. Master password unlocks all of them — switch from the header dropdown.

6 chains preloaded. Add unlimited.
Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, Avalanche out of the box. Add any EVM chain — dApps can request via wallet_addEthereumChain with explicit user approval.

Paste a contract address — symbol and decimals auto-fetch. Send tokens, watch balances per-chain, with Trust Wallet CDN icons.
EIP-747AUTO-METADATA
Plays nice with MetaMask
EIP-6963 multi-provider discovery means Auto Wallet appears in the dApp's wallet picker alongside MetaMask, Rabby, and the rest — no fighting over window.ethereum. Run them side-by-side. Auto-injects only if no other wallet is present; force-inject mode available for legacy dApps.

Auto-lock that fits you
5 minutes for the paranoid, 24 hours for the day-trader, never for the brave. Your call — change it in Settings any time.

Convenient.
Not careless.

Auto-signing only works because the foundation is locked down. Keys never leave the encrypted vault. Origins come from Chrome, not the page. Every rule has a gas-and-value safety net you can't disable.
